At INFOFLEX 2019, TRESU will show flexographic ink supply and machine system solutions, including integrated printing units for converting lines as well as the Flexo Innovator press, meeting the quality, efficiency, and high output demands in labeling, packaging and industrial manufacturing (booth 738, 6th – 7th May, New Orleans Morial Convention Center, New Orleans, Louisiana).
 

Ancillary program optimizes flexo ink supply

TRESU’s ancillary program of ink supply systems and chamber doctor blades automatically regulates the supply of ink and coating media to the press, enabling clean, consistent print results, with improved uptime, reduced waste, faster printing speeds, and minimal manual input. The F10 iCon ink supply system provides stable and controlled ink circulation, by maintaining precise flow, pressure and viscosity levels at predetermined values. The system provides significant material and time savings by automatically returning remaining ink back to the bucket at the end of the production run, and thorough, simultaneous chamber cleaning in a matter of minutes. 

TRESU’s chamber doctor blades, engineered for optimal performance, ink consumption and ink preservation in an enclosed environment, are available with carbon fiber or ceramic surfaces for corrosion resistance and effective automatic cleaning. Patented seals prevent foaming, ink contamination and leakage, while enabling uniform, accurate ink transfer at high printing speeds. For wide web applications (1600mm to 6000mm / 63in to 236.22in) the carbon fiber MaxiPrint Concept features an integrated nozzle with a water-shot mechanism for efficient chamber and anilox roll cleaning. Other TRESU chamber doctor blades include the  SAVEink chamber for narrow web, and FlexiPrint Easy chamber for flexible packaging applications. 

Information about TRESU’s chilling systems for sustainable, efficient heat extraction from flexo presses will also be available. The intelligent iSeries offers an innovative control platform that interfaces directly with the TRESU Internal Diagnostic Monitoring System (IDMS). IDMS is a state-of-the-art, proactive system that monitors the chiller and alerts the TRESU service department of any performance issues, facilitating remote diagnostics and enabling swift remedial action. This system can also be run with offset and digital presses.
 

Flexo Innovator press for lean, high-output, value-added paperboard packaging

TRESU’s Flexo Innovator press, for high-value paperboard packaging applications combines outstanding print quality, high output, fast job changes, sustainable printing and ergonomic design. Available in several widths between 670mm and 1700mm (26.38in to 66.92in), the Flexo Innovator is a custom-configured multi-process, inline printing and converting press for folding carton board, paper, laminates and metallic substrates. Thanks to its modular design, the Flexo Innovator may incorporate multiple processes and ink sets, enabling complex and distinctive packaging designs to be printed and converted in a single pass. Options include water-based, solvent and UV-curable inks, as well as high-end complementary processes such as reverse printing, gravure, inkjet, cold-foil lamination and converting. 

With high-speed unit-to-unit air drying, automated ink supply and sleeve systems, the press provides a stable, efficient printing platform at speeds of up to 800 meters per minute (2625ft/min). It includes features that reduce waste, energy usage and emissions, reflecting TRESU’s commitment to minimising the environmental footprint of flexographic print. 

Efficient energy consumption is achieved with a unique gas heating solution and a software design where servo motors runs with relatively low power. Drying units recycle high proportion of both air inside the dryer and exhaust by means of heat exchange. Chilling systems safely extract heat from the press to external condensers that could return the energy to the incoming cold fresh air.
 

Customized flexo units for integration with manufacturing lines

TRESU will also showcase custom-designed retrofittable flexographic units, for integrated coating, printing and gluing on manufacturing and converting lines. Designed to apply coating media, ink, silicone and glue to a wide range of papers, plastics and nonwoven substrates, the units may be integrated with converting machines for numerous manufacturing applications. They optimize manufacturing processes in markets as diverse as household chemicals, feminine hygiene products, wallpapers, direct mail publishing, cigarettes and food. 

The printing units comprise between one and six flexo stations and are available in widths ranging from 185mm to 4.8 meters (7.28in to 189in) . They include TRESU’s automated ancillary equipment, for controlled printing at speeds ranging from 10m/min to 1000m/min (32.8fpm – 328fpm). The units may be adapted for UV, water-based, solvent or solventless media. 

TRESU has installed over 300 printing units on manufacturing lines. They are being used for a variety of purposes, including applying fire-retardant barriers to cigarette paper, anti-slip coating to baking paper, logos and patterns to detergent pouches and nonwoven sanitary napkins, high-quality graphics to wallpaper and glue for direct-mail newspapers. 

“INFOFLEX 2019 provides an ideal opportunity for packaging printers and industrial manufacturers to learn how TRESU’s flexo ancillary and machine systems can add value to their processes and operations,” comments Scott Hibbs, president, TRESU Americas. “North American customers can be assured of optimized performance thanks to TRESU’s manufacturing and service facility in Dallas, providing rapid-response to queries, 24/7 remote diagnostics, and a quick parts and consumables delivery.”

Flexography is the ideal process for applying these features because of its accuracy, speed and versatility. Using a flexible polymer relief plate that can be imaged relatively cheaply, it applies a wide range of media including ink, varnish, silicone and glue to a variety of substrates including plastic, metallic film, paper, cellophane and non-woven substrates. 

Moreover, units are available that can be customised to integrate seamlessly and perform with stability with manufacturing lines for many industries at speeds of between 10m/min and 1000m/min.  Flexo is capable of achieving precise and uniform laydown at speeds between 10m/min and 1000m/min, thanks to ancillary equipment including a supply system and chamber doctor blade, to automatically control flow and viscosity. controlled ink supply and the design features of the printing unit that facilitate stable printing. 

Custom-designed flexo units can be retrofitted with virtually any converting machine, optimisin manufacturing processes in markets as diverse as household chemicals, feminine hygiene products, wallpapers, direct mail publishing, cigarettes and food.

 

Application examples 

For some industries, an integrated unit leads to the development of new products. One example is baking paper with anti-slip properties. A 1.4-metre unit features a rotary screen system to apply silicone dots of between 5 and 8µm thickness to the back of the paper, providing a grip for the baked products. The paper is then slit to approximately 300mm-widths. 

Because flexo provides a positive (relief) print, the process is capable of high resolutions for printing high-quality wallpaper designs. Furthermore, plate and imaging costs are lower than those for screen, and printing speeds are faster. TRESU has designed a twin-station unit with air dryers for printing the design and wallpaper edge used for accurate positioning on the wall. Carbon fibre chambers with corrosion-resistant surfaces are used as the inks have high pH values. 

A fire-retardant water-based coating applied to cigarette paper ensures the cigarette extinguishes after burning for a maximum of 9mm if smoke is not inhaled. Flexo is a more reliable alternative to the conventional method of applying the coat with spray nozzles, which have a relatively high risk of clogging, and low assurance of consistent coverage. The flexo unit’s circulator assures viscosity control and uniform coverage across the web. TRESU custom-built the coating unit together with an unwinder, slitter and rewinder for a German customer. The rolls of coated papers are then supplied to the cigarettes manufacturing facility.

Perhaps the fastest flexo application, of up to 1000m/min, is the application of glue in direct mail production. TRESU has built a unit for gluing the webs together during the production of a superstore’s weekly brochure for promoting bargains. The unit applies glue to the front and back sides of four webs just after they converge. Stability is achieved with rollers that function without gears and at a high rotation. Working with a co-supplier TRESU supplied an anilox roll with cells in a wave-formation to transfer the glue stably at high-speed, as well as chilling units to maintain temperature below 30°C.

 

Custom-designed unit integration

Including the printing process within the production line, with a flexographic printing unit between the converting and unwinding operations reduces setup times and waste, shortens lead-times, and allows more frequent design change with greater flexibility. There is also no need to rely on a third-party print supplier, simplifying logistics and reducing materials costs.

TRESU, a global manufacturer of flexo units and ancillary equipment, has decades of experience providing a ‘total-system’ approach to integrate the printing process smoothly within existing manufacturing lines. It also provides installation management, training and technical support, so the user gains optimum value from the investment.

Given the breadth of possible applications, there is no ‘standard’ printing or coating unit for integration with a manufacturing line: almost every situation is unique. The first stage in the retrofitting project is a consultation with the customer to understand the many parameters that affect the design.

The application itself is has implications for the viscosity of the coating medium and thus, type of supply system used. Other considerations are width, production speed, available floor space, and the design of the manufacturing line.

The units may be in widths ranging from 185mm to 4.8 metres, comprising one to six printing or coating stations as required. Machines can be adapted for UV, water-based, solvent or solventless media, as well as roll-to-roll, roll-to sheet, and multi-web paths.

Units come with drying and curing systems, as well as complementary equipment such as  rewinders, unwinders, turn bars and bridging equipment to ensure smooth integration.

 

There are four design variations:

  • Direct inline - the unit is integrated into the manufacturing line directly after the unwinder, before the web undergoes the converting process. The manufacturing line is extended to accommodate the printing unit by moving the first segment of the line.
  • 90° Inline Printing Unit - the printing unit is positioned about next to the converting line from a right angle.  After printing, the web passes over a bridge with a 3m drying unit. before descending to the converting line with the aid of a turn bar. 
  • Parallel – where the unwinder and printing unit are configured so the web runs parallel to the converting line.
  • Mezzanine - the printing unit may be integrated directly into the main frame and guarding of the converting machine. 

High-performance air drying

Air drying or curing units are included between each station, with ventilation to ensure all moisture is extracted from the material before conversion. Sensors monitor and automatically control ventilator temperature and humidity. Efficiency is optimised by using a relatively high air velocity and a relatively low heat, and recycling of approximately 85 per cent of the air with an extractor. For some applications, a relatively low drying temperature avoids the risk of tension loss due to loosening fibres.  

 

Automated Ink Supply

Clean, uniform and accurate delivery of the coating media to the material is assured, without manual intervention, thanks to the supply system and chamber doctor blade.  Extensive automation and fast-change features into the unit, to ensure optimum process control, fast setup times and low maintenance.

TRESU’s F10 iCon supply system with automatic cleaning, ensures the coating medium or ink is constantly fed the printing units at optimum viscosity, temperature and pressure levels. It feeds a sealed, chambered doctor blade system at a controlled pressure that prevents air contamination, to ensure a foam-free, clean transfer. This also prevents leakage, minimising cleaning times and emissions. The chamber’s eccentric clamping system allows safe, single--minute blade exchange. Additionally, the supply system performs automatic cleaning cycles changes with minimal loss of ink. During an change cycle, which takes no more than 15 minutes, the remaining ink in the chamber is returned to the pump. The chamber and anilox roll are thoroughly cleaned to remove residue, and the new colour is introduced, automatically.

A control system stores and, in the case of repeat jobs, instantly recalls job recipes, so no re-entry of ink and calibration data is needed.  For customers working with a variety of inks and varnishes, TRESU technicians are available to build a unique database of recipe settings for each job, including, among others, impression settings, print levels, flow rate, air velocity, temperature and register coordinates.

Units come with an intuitive human-machine interface for easy operation. Information from the HMI can also be viewed at the interface of the converting line’s main control panel.

As a versatile process capable of high speeds and high-definition graphics, therefore, flexography is ideal for inline functional or decorative printing. TRESU flexo units with integrated ancillary equipment, enable manufacturers to apply features that enhance the safety, convenience and brand presentation of their products, while preserving optimum performance of the converting line.

Increasingly, manufacturers are looking to apply graphics to the product,
such as floral or geometric patterns, icons and logos, in order to promote trust in the brand and convey quality. 

 

Watch the new animation presenting TRESU flexo printing of sanitary products here.
 

Femcare products with printed graphics are not new – however, until quite recently, achieving this came with significant challenges. Manufacturers have typically  depended on an external supplier, ordering relatively large quantities of preprinted material, and converting it into finished products when needed. This, however, results in significant logistics and storage costs, lengthy leadtimes and high material waste levels. Furthermore, the manufacturer lacks the flexibility to change printed designs without scrapping the remaining stored material.
 

Some manufacturers are seeking to integrate the printing process into the production line, with a flexographic printing unit between the converting and unwinding operations. This single-pass solution not only reduces waste and shortens leadtimes, but allows manufacturers to change printed designs with greater flexibility, reducing setup times and avoiding inconsistencies in production.
 

The new flexo units, using water-based, solvent or UV inks and featuring between one and four colours, can be both specified on new manufacturing lines, and retrofitted into exiting lines. They can be customised in four different ways, according to space and layout constraints. Moreover, with servo drives, a high degree of automation and efficient drying systems included, the unit can integrate smoothly, performing without requiring operator intervention and setup times.
 

The units are designed to handle nonwoven fabric or plastic material between 80 and 320mm width and 12 and 35gsm. They feature controlled web tension, to between 4 and 8N. The key elements of the flexo unit include a supply system with chamber doctor blade for feeding the ink, in an enclosed environment, to an anilox roll. The microscopic cells of the anilox deliver the exact amount of ink required to the printing sleeve, which finally applies the print pattern to the nonwoven fabric.
 

A crucial concern is to include the printing units without disrupting the logistics and operator performance around the manufacturing line.  Space availability – in terms of area or height – is likely to be scarce. As a result, the unit, based on a common impression formation, is contained in a compact housing, approximately 2m depth and 3m length.
 

As a manufacturer of flexo units, drying systems and auxillary equipment, TRESU has developed four ways of integrating the printing process with existing converting machines, based on many years’ retrofitting experience in the manufacturing sector. First, a direct inline printing unit can be integrated into the manufacturing line after the unwinder. The length of the line is simply extended by moving the first segment of the line.
 

If it is not possible to expand the length of the production line, the printing unit may be located beside the line, connected at a distance of approximately 4m. To optimise process flow, the unwinder and printing unit are positioned together. In a 90° configuration, the printing unit, together with the unwinder are situated at a right angle to the converting line, with the web running towards the converting line. After printing, the web passes over a bridge with a 3m drying unit,  before descending to the converting line with the aid of a turn bar.  Alternatively, the unwinder and printing unit may configured so the web runs parallel to the converting line. Finally, the printing unit may be integrated directly into the main frame and guarding of the converting machine.
 

Automated ink supply to optimise process control

An ink supply system with automatic cleaning, as well as chamber doctor blades, ensures that ink is constantly fed the printing units at optimum viscosity, temperature and pressure levels. The sealed, pressure-controlled chambered doctor blade systems enable direct, foam-free transfer of ink or coating to the anilox rollers, ensuring a consistently clean printed image.  This also prevents leakage, minimising cleaning times and emissions. The chamber’s eccentric clamping system allows safe, single--minute blade exchange. Additionally, the ink supply system performs fast ink changes with minimal loss of ink. During an change cycle, which takes no more than 15 minutes, the remaining ink in the chamber is returned to the pump. The chamber and anilox roll are thoroughly cleaned to remove residue, and the new colour is introduced, automatically.
 

A control system stores and, in the case of repeat jobs, instantly recalls job recipes, so no re-entry of ink and calibration data is needed.  At the installation stage, the TRESU technical team works with the customer to build a unique database of recipe settings for each job, including, among others, impression settings, print levels, flow rate, air velocity, temperature and register coordinates. The unit comes with an intuitive human-machine interface that is easy for operators to learn to use. Information from the HMI can also be viewed at the interface of the converting line’s main control panel.
 

High-performance air drying

The printing unit comes with an integrated, high-performance air drying system, which is designed to minimise the risk of material elongation. An internal bypass function secures the controlled air flow in the system during machine stoppages or slow production mode. However, moisture extraction arguably presents a greater challenge, not only because of the web speed, but also to secure dried material before entering the converting process. A controlled process with adequate ventilation is therefore essential.

 

TRESU’s drying solution comprises electrical air drying systems, situated both between printing stations and after the printing unit, to ensure all water is extracted from the material. Efficiency is optimised by using a relatively high air velocity, avoiding the need to use excessive heat which can result in loosening of fibres. It requires a relatively low drying temperature, thus avoiding the risk of tension loss due to loosening fibres and reduces energy requirements. The drying unit includes sensors for monitoring andautomatic control of temperature and humidity in the ventilation system to maintain optimum drying conditions at all times.
 

Drying speeds and energy efficiency are optimised by situating the fan that applies the air and pressure inside the drying hood, shortening the distance from the fan to the air nozzle. This enables heat to be contained within the head and provides better insulation.
 

Summary

A converting line with integrated flexo printing capability means the personal hygiene products manufacturer can meet the demand for branded goods, while having the flexibility to competitively offer shorter production runs, with sorter lead-times, with costs firmly controlled. It even gives manufacturers the option to refresh product lines with more frequent design changes, in response to trends in seasonal or demographic demand.
 

With the assistance and guidance of a flexographic printing technology provider  that has expertise in both the customised unit and the vital ink supply and drying elements of the process, the manufacturer is well placed to gain a long-term return on investment, from a smooth, productive workflow that requires a minimum of extra maintenance.

The company has many years’ experience of the corrugated industry along with expertise in flexo printing and coatings. Vernitech will focus on TRESU’s ink supply systems and sealed chamber doctor blades as well as other TRESU Ancillary products for corrugated and wide-width flexo applications.

“There are many corrugated converters in France and North Africa who can benefit from TRESU’s systems,” said David Michel-Moulu, managing director, Vernitech. “By cutting waste and building efficiencies with chamber doctor blades and advanced ink supply systems, companies can increase machine uptime, speed and print quality while reducing waste and saving time.
The impact these improvements can make on competitiveness and profitability are enormous.”

Michel-Moulu also cites consistency of quality as a major benefit of such systems. TRESU’s chamber doctor blade systems can make a major difference to corrugated converters through efficient ink application and fast colour changes. With a choice of light-weight corrosion-resistant carbon fibre or ceramic construction, systems are designed for printing and coating applications, and are available in widths from 185mm to 6000mm (7.28in to 236.22in).  

Of special interest to corrugated printers, the new TRESU MaxiPrint Concept chamber features an integrated cleaning nozzle with a robustly designed water-shot mechanism for fast, efficient cleaning of the chamber and the anilox roll and is available in widths up to 6000mm (236.22in).

For waste savings and efficiencies in ink management, the TRESU F10 iCon provides stable and controlled ink circulation and automatically adjusts flow, ink pressure and viscosity. Simultaneous ink changes on printing stations take minutes, and when an ink change is required, any ink left in the chamber is returned to the bucket for use on the next job.

As an engineer with a long career in the French paper and printing industries, Michel-Moulu offers consultancy and application support, giving a practical perspective to finding the right solution for customers.

“Apart from the time, waste and productivity benefits of its systems, TRESU’s four-decade long experience in flexo printing gives the company a unique expertise in the sort of engineering necessary for achieving consistent, high-quality print across wide web widths,” Michel-Moulu concludes.

The company’s ancillary programme comprises chamber doctor blades up to 6000mm wide, together with ink supply systems that provide a fully enclosed means of supplying ink and coating media to the press.  They are designed for integration with new and existing presses, they optimise quality consistency, output and press uptime, while dramatically reducing waste, manual input requirements and emissions. 

TRESU’s chamber doctor blades, in light-weight corrosion-resistant carbon-fibre or ceramic constructions, provide clean, uniform printing and efficient drying, at faster speeds. A key feature enabling their high performance is TRESU’s “Pressure Control Technology.” Ink pressure is automatically maintained at optimum levels in the chamber by a long-life rubber seal system that forms an airtight enclosure, eliminating micro-foaming and leakage. With ink at the desired pressure, a liquid barrier forms between the rotating anilox rolls and the chamber, preventing air from entering the cells during production. The chamber doctor blades also feature fast, safe blade exchange as standard, with pneumatic or eccentric clamping systems. 

A highlight of the stand for corrugated applications will be the TRESU MaxiPrint Concept, in 1600mm to 6000mm widths, is a carbon fibre chamber doctor blade with integrated system for fast, efficient water cleaning of the chamber and anilox roll.   The low pressure cleaning mechanism ensures minimal water loss during cleaning. 

The F10 iCon ink supply system regulates ink flow, pressure and viscosity, providing constant, accurate ink density on the printed substrate without air contamination. It achieves thorough automatic cleaning, with a complete ink-change cycle, in 5 to 15 minutes, returning a very large proportion of unused ink to the bucket.   

Henrik Kristensen, vice-president, TRESU Ancillary, comments: “The corrugated industry faces strong challenges to drive waste out of production process, in the face of shorter production runs and higher quality demands, and ink supply plays an enormous role in printing performance. TRESU ancillary solutions have proved successful in keeping flexo printers productive and competitive, delivering significant savings through minimising manual input, reduced ink waste and increased production speeds. TRESU retrofitting programmes, managed by experienced engineers, can bring existing presses - whether line, common-impression or stack formation - to the highest standards of performance for a relatively fast return on investment.”

New UV and water-based coatings have been developed to create an exciting range of effects, enabling creative and exciting designs that are tactile as well as visually enticing. Innovations in flexo ink supply enable these features to be applied efficiently in a single pass at speeds of up to 18,000 sheets per hour.

Perhaps the most common aesthetic effect associated with coating is a full gloss or matte cover, applied by a flexo process after offset printing. UV coatings are increasingly preferred as they provide gloss values that can be 10 to 15 points higher than those offered by conventional alternatives. With two coating units, stunning effects can be created using a combination of matt and gloss varnishes.

Metal-pigment silver and gold inks are used to create innumerable metallic tones on folding carton packaging or high-quality brochures and magazines. Their intensity results in a high brilliance even when only a thin layer is applied. These inks are available in UV or conventional varieties and may be applied before or after the printing processes.

Glitter-effect and iriodin high-lustre pearl inks produce sparkling reflections that deliver brilliance, bringing and vibrancy to high-quality commercial and folding carton products.

It’s not only the eyes that can be tempted: scented coatings provide a powerful promotional tool for fragrances, foods and beverages. Micro-encapsulated scents are released when the surface is rubbed providing a unique enhancement.
 

Flexo – the solution for functionality

The flexo process provides the optimum solution for applying coating over offset-printed graphics. Flexo coating media have the chemistry that enable fast air drying or curing at higher speed higher glossiness.  Furthermore, a flexo system can apply thick, consistently accurate and uniform layer of coverage, which is critical to functionality – avoiding scratches and yellowing.

Flexographic technologies from TRESU Group offer complete inline coating concepts and solutions – from ink/coating management and application to drying and waste reduction with high levels of automation – to enable traditional printers and converters to offer customers the latest competitive solutions for adding value and building brand appeal:

At PrintPack India 2019, TRESU Group, together with its regional agent CGSASP, will show its ancillary solutions for automating ink supply and enhancing quality, efficiency, and output on flexographic label and packaging presses (Stand G12, Hall 9, India Expo Centre, Greater Noida, NCR Delhi, 1-6 February). The company will also present information about its Flexo Innovator, an inline flexo printing and converting machine for paperboard applications combining high speed, minimised waste and fast setup times.  

TRESU’s Ancillary division will highlight the vital contribution its programme of chamber doctor blades and ink supply systems play in optimising print quality, waste elimination and machine uptime.

 

Pressure-control with chamber doctor blades for all flexo situations

Covering label, paperboard, flexible packaging, tissue and specialist coating applications, TRESU’s chamber programme is available for all web widths between 185mm and 6000mm. Using the company’s unique “Pressure Control Technology”, the chambers eliminate air contamination and microfoaming, to ensure clean, uniform print on the substrate. A long-life rubber seal system provides an airtight enclosure, preventing leakage, and maintains consistent ink pressure. Ink quality is assured by a liquid barrier, formed between the rotating anilox rolls and the chamber, preventing air from entering in the cells during production. The chamber doctor blades also feature fast, safe blade exchange as standard. Light-weight, corrosion-resistant carbon fibre and ceramic alternatives are available. Chamber blades may be supplied with new presses and retrofitted on existing ones. 

For web widths from 1600mm to 6000mm (63in to 236.22in), the new MaxiPrint Concept chamber features an integrated cleaning nozzle with a robustly designed water-shot mechanism for fast, efficient cleaning of the chamber and the anilox roll. A low-pressure shot mechanism ensures minimal water loss during cleaning. The TRESU P-Line pneumatic clamping system also ensures fast, safe blade exchange within two minutes. 

The TRESU FlexiPrint Reservoir SAVEink chamber doctor blade is for narrow web flexo applications up to 800mm wide. With an integrated high-capacity reservoir, the TRESU SAVEink is ideal for process and spot colours as well as high ink transfer printing, without the need for a connected pump. It is sealed and locks into place in seconds without the risk of spilling or ink contamination. Ink may be added to the reservoir without stopping the press.

Also featured are other models in the FlexiPrint range: FlexiPrint Basic and FlexiPrint Reservoir, offering high price-performance ratios. These doctor blade systems maximise print quality, efficient ink use, and savings on waste. FlexiPrint Basic offers high-quality doctoring for anilox rolls from 80mm to 2000mm in width and between 60mm and 400mm in diameter. Suitable for water, solvent and UV-curable inks and coatings, FlexiPrint Basic features TRESU’s patented ‘E-Line’ eccentric clamping system and seals for fast, accurate and easy doctor blade changes, and protection of ink quality. FlexiPrint Reservoir is designed for water-based and UV coatings. It can be manually filled or used with a pump. The easy-load cassette enables fast colour/coating changes and the patented seals mean that surplus ink can be reserved in the chamber for future use.

 

Supply systems and circulators for consistent ink and coating application

TRESU is recognised for its ink supply systems, which can be part of the configuration of a new press or retrofitted. The F10 iCon ink supply system regulates ink flow, pressure and viscosity, to ensure a constant, accurate ink density on the printed substrate without air contamination. An energy-efficient system, it provides thorough automatic cleaning with a complete ink change cycle taking between 5 and 15 minutes. As part of the automatic cleaning, a very large proportion of the unused ink can be returned to the bucket. Information on TRESU’s full range of coating circulators and conditioners for high-viscosity coatings will also be available on the stand. 

The flexo process provides the optimum solution for applying coating over offset and digitally printed graphics. Flexographic ancillary technologies from TRESU, including chamber doctor blades, circulators and conditioners, can be integrated with offset and digital presses to apply sensually appealing matte, gloss and textured coatings to commercial and packaging print-work,consistently and accurately. Equipment is also available for high-viscosity and specialist coating effects, including Iriodine and mettalure. TRESU also provides drying technology, for fast air drying or curing at higher speed higher glossiness.    

 

Flexo Innovator: advanced inline flexographic printing

Information, samples and animations about the TRESU Flexo Innovator flexo printing machine for advanced, high-quality, high-speed packaging production for folding carton board, paper, laminates and metallic substrates will also be available on the stand. With its customised line configuration and in web widths from 670mm to 1700mm, the Flexo Innovator is able to integrate water-based, solvent and UV-curable inks, as well as value-adding complementary processes, including double-sided printing, gravure coating (double-sided), inkjet, cold foil and lamination. Speeds of up to 800m/minute make the Flexo Innovator an advanced, versatile solution for both short and long-run production.

 

Global support

TRESU adds value to its customers’ operations with a responsive global support network, with subsidiaries and agents providing technical and sales assistance, training, and application consultancy to optimise returns on investment. CGSASP Pvt Ltd, based in New Delhi and representing TRESU Group in India, provides a first point of contact for enquiries, as well as a local source of support and consumable products.

“While the packaging printing market in India is strong and vibrant, we are increasingly competing against regions with high levels and fresh investment,” says Kunal Gandhi, managing director, CGSASP. “Rising quality standards and demands for fast-turnaround times with shorter run lengths require modern equipment and systems. TRESU’s retrofittable chamber doctor blades, ink supply and other ancillary equipment are ideal for improving production efficiency and competitiveness. 

“With fast responses, a strong support network and application expertise, CGSASP and TRESU offer a dynamic partnership with local knowledge to Indian converters,” he concludes.

Flexo - the key to sustainability in package printing

Short text:
With environmental concerns becoming a high priority for consumers, retailers and brand owners are taking a more critical look at the carbon footprint of their packaging supply chains. As brand owners increasingly choose paperboard instead of plastic, the inline flexo press, with its reduced waste and emissions, offers the optimum combination of sustainability, quality and productivity, argues Allan Sander, vice-president, TRESU Solutions.

As far as environmental perceptions are concerned, 2018 can be regarded as a pivotal year. The scale of the damage to the climate from greenhouse gas emissions and plastic waste is becoming apparent, bringing with it a profound change in attitudes: consumers are shunning non-recyclable packaging and demanding government to outlaw their use. 

Hardly a week goes by without being confronted by harrowing images or alarming studies: consider the marine life choked by bags and netting, floating islands of rubbish and beaches strewn with decades-old litter, as well as reports of carcinogenic microplastics permeating the food chain.

Plastic can take centuries for plastic to break down – scientists estimate that it will take up to 450 years(1) for plastic bottles to disappear -  and yet every year, between 5 and 13 million tonnes are added to the oceans(2). PET, the most commonly used material for plastic bottles, is being recycled at rate of only seven percent: brand owners generally do not consider the material in its recycled state to be clear enough, and there are simply not enough facilities to keep up with the dramatic surge in consumption.  Attention has also turned to the poor recyclability of disposable paper cups, as a high proportion of them contain a polypropylene lining that very few waste-handling facilities(3) have the capability to process.

New statistics from the European Parliament suggest that bottles and lids account for a fifth of all marine litter in EU waters, so it is no wonder that the packaging and quick-service restaurant industries have become targets for criticism.

Government legislation is being passed to curb plastic use and encourage more responsible consumer habits: Kenya introduced a ban on the production and sale of plastic bags in 2017, and its success is inspiring at least four other African nations(4) to follow suit.  The European parliament voted overwhelmingly for a complete ban on various single-use plastic products such as cutlery, plates and straws, effective from 2021.

There is also an urgency to act at a global level to reduce carbon dioxide emissions that, at 38bn tonnes annually, is far greater than the planet’s photosynthesising plants and rocks can absorb. This has already led to a rise of global surface temperatures by 0.8°C since the start of the industrial age – and a rise of 2°C is as much as the world can adapt to without long-term devastating consequences(5). In this context, this summer’s forest fires in the Arctic circle can only be seen as a prelude.

 

Innovation offers growth opportunities for paperboard packaging

Faced with a consumer backlash, brand owners and retailers are realizing that sustainability is not just a matter of saving costs – reputations are at stake. It is imperative that market players look closely at materials and processes that minimize the environmental burden.

It is encouraging to see global market leaders investing heavily in finding eco-friendlier alternatives to plastic disposable cups, lids and containers.

Starbucks is investing in research to develop fully recyclable cups(6), using biodegradable plastic, while Tetra Pak is developing paper straws and caps made from a polyethylene byproduct of sugar cane(7).  Water-based polymer coatings have been developed that can safely dissolve when the carton cup or plate is repulped, so it can be sorted with regular paper.

These developments make paper and carton packaging a practical and economically viable alternative to plastic for a variety of liquid food and dairy segments, as well as for secondary packaging.

 

Flexo for lower emissions and lower waste

The switch to carton packaging makes it possible to use printing and converting processes that produce lower levels of emissions and waste. Gravure and offset processes tend to use inks with relatively high solvent content, and involve costly tooling and engraving processes with high carbon footprints.  Flexo offers significant sustainability advantages compared with other printing processes, with eco-friendlier water-based inks, recyclable polymer plates and sleeves, and emerging LED-UV curing technologies.

Thanks to advances in press and ancillary technologies, flexography is becoming a greener and ‘leaner’ process, requiring less energy and water, while generating less material waste and emissions.

Inline flexo is beneficial for fast water-based printing because a longer web path between printing stations is possible, making unit-to-unit drying possible, and thus cleaner colour printing.

 

Air drying systems

The key to high-performance, sustainable drying of flexo inks lies with using air velocity at the lowest possible temperature, while recycling as much air and energy as possible. Reducing drying temperature in turn reduces energy requirements and eliminates the need for chill rollers afterwards.

Drying speeds and energy efficiency are optimised by situating the fan that applies the air and pressure inside the drying hood, shortening the distance from the fan to the air nozzle. This enables heat and noise to be contained within the head and provide better insulation.

 

The optimum air velocity – temperature combination varies according to factors such as the thickness of the ink coverage, substrate type, web speed, and time spent in the drying unit. TRESU’s research and development specialists have worked to devise energy-conserving drying systems for numerous printing applications, often in partnership with substrate manufacturers.  Additionally, power consumption and CO2 emission levels from a hot air drying system are only 25 percent as much as those associated with UV-curing.

 

Optimising energy efficiency

An important energy and emission-reducing factor is the ability to recycle energy.  Efficient energy consumption is achieved with a gas-heating solution and a software design where servo motors run at relatively low power. Drying units recycle a high proportion of the air inside the dryer and, from the exhausted air, much of the energy is recycled by a central heat exchange module. In the case of TRESU drying systems, up to 80 per cent of the air inside the dryer can be recycled.

 

Temperature control

Chilling systems safely extract heat from the press to external condensers, which can return the energy to the incoming cold fresh air. The chilling system’s ‘split system’ design does not interfere with the printing process or place additional demands on the facility’s existing heating, ventilation or air-conditioning systems. In this way, up to 60 per cent of the exhaust energy can be recycled.

 

Reducing material waste

Today’s inline flexo machines feature advanced controls and ancillary equipment to ensure stable printing at faster speeds with minimal substrate or ink waste.

Automated register controls and spectral colour measurement systems enable the press to meet tight targets at the beginning of the production run, limiting startup waste to within the length of the press. Web controls also reduce waste, by holding register as the press ramps up at the start, and when it reduces speed at the end of the production run.

 

Automating ink supply

Automated ink supply systems provide the solution for reducing ink waste - as well as clean printing at high speed, elimination of leakage and increased machine uptime.

A supply system works harmoniously with a chamber doctor blade that features a rubber seal system, creating an enclosed environment that stops leakage, emissions and any opportunity for the ink to react with the atmosphere.

Automating characteristics like viscosity, pH value and ink temperature is an effective way of reducing waste.  The ink supply system automatically regulates flow rate, pressure and viscosity, as it feeds ink to the chamber. In turn, the chamber feeds ink to the cells of the rotating anilox roll. Exactly the right pressure is maintained so there is a constant presence of ink between the blade and the anilox roll during production, stopping air bubbles from entering. In turn, this ensures blister-free printing, throughout the production run, at speeds of up to 800 metres per minute.

After the production run, the supply systems can perform automatic ink changes. They return almost all the ink remaining in the chamber to the bucket, cleaning without human intervention in minutes. At TRESU we have helped packaging converters achieve ink yield improvements of 30 per cent, by modernising their presses with an enclosed ink flow, featuring the F10 iCon supply system.   Ink supply systems and circulators are also available for handling water-based, UV-curable and solvent coating media with relatively large particles and higher viscosity.  

The enclosed chamber system enables more economical use of water for cleaning. First, with no leakage, the environment surrounding the press is likely to be cleaner. Second, carbon fibre chamber surfaces repel the ink enabling thorough cleaning with less water. There also self-cleaning chambers, such as TRESU’s MaxiPrint Concept, feature nozzles that jet water at high pressure, economising further on cleaning water.

Stable systems make flexo viable for more jobs

By incorporating the drying, ancillary and automated control systems, described above into an inline flexo press, therefore, stable printing is possible, at speed, with minimal defects or waste. This means flexo can achieve high definition up to at least 70 lines/cm with precision, not only faster, but at a lower unit cost.

With its lower emissions and the flexibility to include sophisticated converting processes, water-based flexo becomes the process of choice for numerous applications that were once only possible with gravure or offset. Examples include simulations of metallic foil to double sided coatings that protect the carton against moisture and grease.

 

Summary

A printing press should be an investment that brings returns for 20 years or more. There is a great responsibility to give careful consideration to the machine specification, because over such a long lifespan, this makes a big difference to the converter’s overall environmental – and financial - performance.

Undoubtedly, there is also a financial incentive to implement sustainable processes and practices, because the reduced consumption of materials, logistics, manual input and energy they bring results in lower cost-to-print and, in turn, greater profitability.

Arguably though, there is a yet greater motivation for the packaging value chain to care about how they affect the environment, than the profitability of the production line – important though it is.

Brand owners increasingly recognize that their market success and relevance depends on a good reputation for sustainability, among more socially aware consumers. They also face increasing pressure from a growing number of ‘ethical’ investors(9), as well as politicians, who see more stringent environmental legislation as a vote-winner. We can thus expect packaging buyers to look more closely at the environmental record of their suppliers.

With a modern inline flexo press, a packaging supplier is well-placed to show leadership in this area: it provides the flexibility to compete for short and long production runs, and the opportunity to contribute to a sustainable value chain as a “Green Technology Ambassador”.

One of the major challenges in the printing industry is to achieve standardised, automated machinery that makes production more efficient and uniform. This is related to the fact that the art of printing is an ancient craft, and even if modern machines have made their mark, the production of printed material still involves a lot of manual work.


 

Ved_ventilblok_800

Processes such as ink changes, cleaning and control of the ink’s viscosity, pressure and flow are still carried out manually in many factories, and by their very nature they increase the risk of human error. Furthermore, production is often in standby mode for lengthy periods during cleaning and ink changes.This was the background for TRESU Group’s decision to create a system solution that could eliminate the manual processes and simultaneously streamline and automate the process in full. 

TRESU Group located in Denmark, produces large printing machines and ancillary equipment for flexo printing for companies that produce everything from cardboard packaging to scratch cards. In 2012 they first sat down and thought about an automated pump solution that would be compatible with all kinds of printing machines. “We set ourselves four goals: we wanted to improve the production time, guarantee quality, simplify handling and reduce waste,” explains Christian Fogh-Hansen, R&D Manager at TRESU Group.

 

Would ink destroy the valves?

Their ambitions were high, but it turned out to be an even bigger challenge than expected. The system had to be able to handle both ink changes and cleaning automatically, and the first drawings were a sea of valves and ducts criss-crossing each other. The early models looked like birds’ nests, with complex three- and four-way valves. 

TRESU therefore contacted Bürkert, a company with extensive specialist expertise of valves that also develops complete, customised system solutions. “We needed Bürkert’s expertise to be able to translate the concept from theory into practice, and we knew that they had some robust on/off valves that we might be able to use,” explains Christian Fogh-Hansen. 

As the name suggests, on/off valves have only two settings, and they were to simplify the structure of the system. But the all-important question was whether the valves would be able to cope with the very thick, aggressive printing inks. Water-based inks are made of plastic, and in order for the plastic to be soluble and become liquid, a pH-regulating agent has to be added so that the level is above 8.2. Then, when the pump and the valves have to be cleaned of the ink, a cleaning liquid with an even higher pH level is sent through the system. 

Ole Madsen, who is a Sales Engineer at Bürkert, suggested a model 2000 angle seat valve for this task, but he wanted to make sure that the valves would be able to meet the customer’s requirements.“We’d not used the valves before in media with such a high viscosity, and we weren't sure whether we could deliver the desired number of connections while still guaranteeing an effective cleaning process,” he says. 

Ole Madsen and TRESU turned to Bürkert’s Development Department in Germany to discuss the task with product specialists in the systems house. In Germany they had experiences of similar assignments, and after a thorough review of requirements for the solution, they agreed that the 2000 model was ideal for this task. TRESU therefore initiated test runs in the specific application environment. The tests were successful. Calculations showed that the valves would last around 35 years at maximum pressure.“That was more than enough,” confirms Christian Fogh-Hansen.

  

Manifold made several functions possible

TRESU and Bürkert then initiated a close collaboration on the creation of an adapted system solution, and as the development phase proceeded, the solution was optimised several times. The finished solution was extremely compact. Along the way, 25 valves were reduced to 14, and to meet all of TRESU’s functional requirements the valves and other equipment were mounted on one single manifold, which linked together the various functions.

The plastic material used for the manifold was also extremely important, as the system had to be able to handle both water-based and solvent-based inks. When solvent-based inks are used, the equipment must have ATEX approval. The system solution also met this requirement.

one single manifold in order to meet TRESU’s functional requirements. Illustration: Mads Moltsen

 

The design process has been a partnership between TRESU and Bürkert who worked according to an interactive model, in which they first of all developed the individual components and then assembled everything. 

“In such a process, we at Bürkert are not just a supplier, we’re involved in the whole process as a business partner, from advice and draft solution to prototype production, testing and delivery. It’s this partnership and the close dialogue with the customer about their process that create optimal system solutions. The customer’s challenges are our challenges, and achieving success with a combined system solution is a joint process, but I think we’ve definitely managed it,” says Ole Madsen.

 

Dramatic results

The results of these efforts is a digital, automated pump system known as F10 iCon, which TRESU is already supplying to several companies, where it has resulted in a major boost in production. In one company, the production time was improved by 30 per cent, and in another one they are now producing 10,000 square metres of packaging per hour compared with 7,000 before implementation. This is because the automatic pump system is much faster when cleaning the machine and changing inks. 

A printing machine can handle up to 24 printing systems with the same number of individual inks, and each ink requires a pump system to circulate the ink. In a traditional printing system, where ink changes and cleaning take place manually, it will typically take around ten minutes per ink. With the TRESU F10 iCon, it takes 5-10 minutes in total for all inks. 

This means not only an improved production time, but also a quicker change from one print job to the next. For TRESU’s customers, it can therefore be profitable to deliver smaller print runs, which their customers are demanding. “In the printing industry, processes are handled very differently. Every single printing facility has its own workflows and ideas about how things should be. We’ve developed a standardised system solution, and after a detailed introduction customers have been able to see the benefits of the system, and so far it’s produced really good results,” says Christian Fogh-Hansen.

Using TRESU’s Flexo Innovator printing line, with Lohmann’s compressible DuploFLEX® 5.2 foam mounting tape securing high-definition plates, the companies reproduced in 60lpc resolution an 1889 self-portrait by post-impressionist artist Vincent van Gogh, made challenging because of its vivid colour contrasts and fine brush strokes. 

The painting was printed in four water-based colours on 240gsm full-coated paper, followed by UV-treatment with the Flexo Innovator at TRESU’s Kolding, Denmark-based Demo Center. 

TRESU’s Flexo Innovator printing line, with its stable platform, unit-to-unit air drying and the company’s own enclosed chamber doctor blade system, ensured register accuracy and uniform, clean ink transfer at speeds up to 800m/min. The press has the capability to integrate water-based, UV and solvent ink sets as well as a host of added-value finishing processes inline. 

To accurately reproduce the highlight areas, a soft Kodak NX plate was selected, with microdots capable of reproducing tonal ranges from 0.5% to 100%. Lohmann’s 0.55mm-thick DuploFLEX® 5.2 compressible foam tape, with a pure polyethylene foam carrier, has a smooth surface, absorbing the excess pressure, to protect the plate’s microstructures but enable the desired level of ink transfer when the plate makes contact with the substrate.  

Thomas Holzer, market manager graphics EMEA at Lohmann, comments: “The aim of this project was to print in flexo a job that normally executed in offset, and to compare results in terms of resolution, definition, register, tonal range and colour intensity. Using a challenging artwork, we have shown that through careful selection of compatible components, flexo printing quality is at least equivalent to other processes. This provides packaging converters and brand owners the opportunity to save costs thanks to flexo’s workflow efficiencies, higher speeds and versatility with many substrate types, while getting the same excellent results. 

“This self-portrait was selected, in Lohmann´s new marketing campaign, to pay homage to the printers, because every print should be a masterpiece,” continues Holzer. “It goes to show that getting maximum quality out of flexographic printing is real artistry.” 

For more information about Lohmann's DuploFLEX® foam mounting tape, and inspiration for achieving flexographic excellence on folding carton, self-adhesive labels and flexible packaging, visit:

Inline flexo: a cost-effective alternative to gravure

Short text:

by Allan Sander, vice-president, TRESU Solutions

Less than a generation ago, the suggestion that converters should consider moving from gravure to flexo would have been highly unusual. In fact, many far-sighted and cost-conscious converters dared to do that, pushing limits of every aspect of flexographic printing from plate making, press and register controls, automatic web inspection, and advanced finishing.

Today, as they say, it’s a whole new ball game. There have been major advances in plate materials and processing, faster mounting systems, more advanced press controls and inspection systems, new approaches to inking, and innovative concepts in press design. Each of these brings benefits to quality, efficiency, cost-effectiveness, and waste and energy reduction. 

Three other important changes have influenced today’s packaging converting markets: the huge growth of big brands; the almost equally large growth of “own brands”, and the consequent changes in the overall dynamics of world economies. Legislation regarding the information required on packaging about ingredients, origins, nutritional values as well as environmental compliance have also impacted the packaging market. Variations in national and regional laws have played a significant part in the need for shorter run-lengths. 

The combination of these factors has resulted in a transformation in the way that packaging is ordered, printed and distributed. The sum of these technical, environmental and economical elements has shifted the viabilities of printing processes. Flexo has emerged as the printing process that delivers more than ever before with high-quality standards, production speeds, and cost-effectiveness. Moreover, inline flexo presses have demonstrated the ability to handle jobs formerly printed with gravure presses using water-based inks and coatings on a wide range of substrates.

 

Meeting new demands from end to end

TRESU’s Flexo Innovator is an inline press available in widths from 670-1700mm that can operate at speeds of 600m/minute minute or optionally higher, compared to typical gravure press speeds of 200-300m/minute. These high speeds are in part possible because of unit-to-unit drying (or curing, if using UV inks). Because of its line formation, double-sided printing is easily possible without using a turn bar. 

Prepress for inline flexo solutions like the Flexo Innovator is faster and less expensive than gravure cylinder engraving, and does not produce hazardous waste. These are key advantages when handling shorter as well as long runs. Flexo plate preparation is cost-effective for packaging converters with web presses to bring in-house, while gravure imaging is most often out-sourced, with demanding investment, logistical and time implications. 

Use of sleeve technology for both printing plates and anilox rolls accelerates job change-overs and greatly reduces waste in achieving register. With the added aid of automated controls, start-up waste with inline flexo is limited to about the web length of the press. The combination of higher speeds and faster job changes results in higher productivity. Also contributing to the efficiency are faster and easier cleaning and maintenance made possible by the high level of accessibility of the press units that inline flexo uniquely offers. The enclosed chamber doctor blade and inking system with automatic ink recirculation has automatic cleaning of the chambers, doctor blades and anilox rolls. 

TRESU’s F10 iCon ink supply system adjusts ink flow automatically, controlling pH, pressure, viscosity and temperature. The sealed chambers prevent ink from becoming contaminated so excess ink can be safely returned to containers for future use. This closed ink loop also means that there is less evaporation, as well as a more pleasant, presentable press room environment. Leakage and emissions are also prevented, while an efficient clamping system enables doctor blade changes in less than two minutes. The pressure control prevents micro-foaming at high speeds and its consequential impact on print quality. While an important feature of the Flexo Innovator, the F10 iCon ink system can also be specified or retrofitted to other press types.

 

Understanding the whole concept

While each of the features of the Flexo Innovator makes its own contribution to quality, efficiency, and waste-saving, the power of the concept is further enriched by its ability to integrate added-value inline finishing operations. 

For packaging converters required to produce shorter runs to tight budgets and deadlines, the integration of as many print enhancements or finishing processes as possible contributes to profit margins, throughput and reduced time-to-market. 

For example, the addition of metallic effect inks that resemble foils, and protective or enhancing coatings in a single pass, can be a strong competitive advantage. Inks and coatings of different sets and viscosities (water-based, UV curable and solvent) can be accommodated by the inking systems and optimal drying/curing equipment placed after each unit, for dry unit-to-unit printing.

 

Lean, green technology

The automation and efficiency of the inline press enables lean and sustainable production. In addition to ink savings and reduced start-up waste, air from the drying units is recycled via a heat exchange module and returned at the desired temperature and humidity levels. Similarly, heat can be extracted from chilling units for recycling. 

The Flexo Innovator can be readily extended for additional colours, special coatings, double-sided printing, or finishing processes. For example, a gravure module for coating may be added for special applications, or an inkjet system for coding and marking. The press configurations maybe roll-to-roll, roll-to-sheet, roll-to-plate cutter or roll-to-rotating die cutting Printing units not in use during a run can be prepared for the next job because of the easy access possible with ground-level units.With in-built “green” technology features, the Flexo Innovator can help brand-owners as well as packaging converters meet their companies’ environmental objectives. 

Flexo Innovator presses can be built to meet individual customer requirements in mid or wide web widths, and with repeat lengths up to 1060mm for maximum application flexibility. TRESU’s training for operators and maintenance crews is comprehensive and thorough, while its worldwide network of support engineers will help to ensure optimal performance and maximum uptime.  

It’s a different world to that of a generation ago. Markets, technologies, and economies have changed, and the quest for quality intensified. Responding profitably to today’s demands requires a new approach: inline flexo with its advanced systems offers a powerful, competitive and sustainable solution for today, and tomorrow.

At Labelexpo Americas 2018, TRESU Group will showcase complete ancillary solutions for automatically regulating ink circulation on flexo presses for more efficient label and carton board production. There will also be information about its Flexo Innovator printing line for high-speed paperboard applications and coating systems for digital folding carton lines. 

TRESU’s ancillary solutions, comprising chamber doctor blades and ink supply systems, provide enclosed, automatically controlled ink and coating circulation, resulting in clean print, uniform ink density, reductions in material waste and makeready times, and faster production speeds.

Making its debut at a Labelexpo series exhibition is the new FlexiPrint Reservoir SAVEink chamber doctor blade, for narrow-web flexo applications up to 800mm (31.5in) wide. Its integrated reservoir contains a large ink volume, making it ideal for application of normal and spot colours, as well as high ink transfer printing, without the need for a connected pump. Ink may be added manually without stopping the press, giving the system flexibility for long and short-run production. 

The sealed chamber easily locks into place in seconds, so there is no risk of spilling or ink contamination. Doctor blades are in a pre-set position, without the need for further adjustment, ensuring optimal anilox contact with minimal wear. An automatic indicator shows when blade replacement is necessary. 

TRESU’s chamber doctor blade systems maximise print quality, efficient ink use, and savings on waste. Using the company’s unique “Pressure Control Technology”, the chambers eliminate air contamination and microfoaming, to ensure clean, uniform print on the substrate. A key feature of the technology is a long-life rubber seal system that provides an airtight enclosure, preventing leakage and enabling ink pressure to be maintained at consistently high levels. A liquid barrier forms between the rotating anilox cells and the chamber, preventing air from entering in the cells from transferring during production. The chamber doctor blades also feature fast, safe blade exchange as standard. 

The chamber programme is available for all widths from 185mm to 6000mmm (7.28in to 236.22in), and includes lightweight, corrosion-resistant carbon fibre and ceramic variants.  They cover label, flexible packaging and paperboard printing and coating applications. 

Another product highlight is the carbon-fibre MaxiPrint Concept chamber, in widths of 1600mm to 6000mm (63in to 236.22in).  Its integrated cleaning nozzle with low-pressure water-shot mechanism efficiently cleans the chamber and anilox roll, fast, with minimal water loss.

 

Automatic ink supply and temperature control systems

TRESU supply systems automatically control flow, pressure level and colour density, to provide consistent print quality without air contamination, and thorough, fast simultaneous chamber-cleaning. As part of the automatic cleaning, a very large proportion of the unused ink can be returned to the bucket, resulting in significant long-term ink savings.  The chambers can be retrofitted as an upgrade of existing equipment.  

TRESU’s F10 iCon ink supply system, suitable for inks of standard viscosity, provides a complete chamber cleaning and ink change cycle taking between 5 and 15 minutes. Information on TRESU’s full range of coating circulators and conditioners for higher viscosity applications will also be available on the stand.

TRESU provides a complete container-to-substrate ink logistics solution, developed on a bespoke basis to meet the printer’s specific application needs. A closed-loop system, inkLink provides effective process control for uniform quality, less waste and reduced costs.  

A large sales, technical and IT support team at the Dallas-based subsidiary, TRESU Americas, serves North, Central and South American customers with a rapid supply of consumables, remote performance monitoring, diagnostics, training and consultancy. The subsidiary also includes extensive manufacturing facilities.

 

Efficient coating for digital packaging printing

TRESU also provides coating systems for integration with sheet-fed digital folding carton printing presses. These apply added-value full-surface and spot coatings as well as metallic embellishments directly after the printing stage. The TRESU Pinta is available for Xerox iGen presses, and the TRESU iCoat 30000 is designed for use with HP Indigo 30000 digital presses. Both perform at the same speeds as the presses and offer setup times of less than five minutes. Additionally, TRESU supplies a comprehensive range of consumables such as varnish media, tapes and sleeves, as well as cutting equipment, thereby covering every element in this coating workflow. 

 

Setting new standards – the Flexo Innovator

Also on the TRESU stand will be information, animations and samples that demonstrate the TRESU Innovator inline press for advanced, high-quality, high-speed packaging production with folding carton board, paper, laminates and metallic substrates.Custom-configured in web widths from 670mm to 1700mm (26.38in to 66.92in), the Flexo Innovator is able to integrate water-based, solvent and UV-curable inks. It can include a host of value-adding complementary processes, including double-sided printing, gravure coating (double-sided), inkjet, cold foil lamination and converting.

Designed to meet the demands of printers and brand owners, TRESU printing presses and ancillary equipment deliver print quality, speed and reliable cost-effective production. TRESU’s skilled manufacturing, sales, and support team in Dallas, Texas, provides service, support and consultancy to customers throughout North America and builds on TRESU’s 35 year-old tradition of high-level service. Its global presence and experience makes TRESU a strong partner for both international flexographic and digital printers, and brands.

 

Systems for success

On its booth at PRINT 18 will be a selection of TRESU’s leading ancillaries including carbon fibre and ceramic doctor blade chambers, the F10 iCon automatic ink control system and the MaxiPrint Concept chamber. Videos, information and samples of other TRESU ancillaries will be available as well as for its flagship Flexo Innovator press.

 

The Flexo Innovator is a versatile, custom-configured multi-process inline printing and converting press for folding carton board, paper, laminates and metallic substrates. Available in web widths from 670mm to 1700mm (26.38in to 66.92in), the press is an efficient alternative to labour-intensive central impression presses. It can integrate water-based, solvent and UV-curable inks and high-end complementary processes in a single operation. With speeds up to 800m/minute (2625ft/min), the press features unit-to-unit drying, automatic ink supply and sleeve systems.

 

Inline architecture means that all units are easily accessible, and make-ready preparations can be made on unused units while the press is running. Handling multiple processes saves time in moving materials to off-line finishing equipment, reducing the risk of handling damage.

 

Many of the features and options of the Flexo Innovator press are available for retro-fitting to existing presses.

 

Ancillaries and options for quality and efficiency

TRESU’s chamber doctor blade systems can make a major difference to printers through efficient ink application and fast colour changes. Options include a choice of light-weight corrosion-resistant carbon fibre or ceramic construction. Both systems are designed for label, flexible packaging and paperboard printing and coating applications, and are available in widths from 185mm to 6000mm (7.28in to 236.22in).  

 

Improved print quality is another benefit of TRESU’s chamber doctor blade systems. “Pressure Control Technology” prevents micro-foaming and ensures clean, uniform print – even for high-viscosity metallic coatings. A long-life rubber seal system provides an airtight enclosure, preventing leakage, and maintains consistent ink pressure. Ink quality is assured by a liquid barrier, formed between the rotating anilox rolls and the chamber, preventing air from entering in the cells during production. The chamber doctor blades also feature fast, safe blade exchange as standard.

 

For web widths from 1600mm to 6000mm (63in to 236.22in), the new MaxiPrint Concept chamber features an integrated cleaning nozzle with a robustly designed water-shot mechanism for fast, efficient cleaning of the chamber and the anilox roll. A low-pressure shot mechanism ensures minimal water loss during cleaning. The TRESU P-Line pneumatic clamping system also ensures fast, safe blade exchange within two minutes.

 

The new SAVEink chamber, for narrow web applications, and FlexiPrint Easy chambers, for flexible packaging, use a light weight CFC chamber with carbon fibre ink-repellent surface with high corrosion resistance. The SAVEink chamber is light for fast and frequent job or ink changes and features a pre-set doctor blade for precise application control, for press widths up to 800mm (31.5in).

 

Automatic ink supply and temperature control systems

The F10 iCon ink supply system regulates ink flow, pressure and viscosity, to ensure a constant, accurate ink density on the printed substrate without air contamination. An energy-efficient system, it provides thorough automatic cleaning with a complete ink change cycle taking between 5 and 15 minutes. As part of the automatic cleaning, a very large proportion of the unused ink can be returned to the bucket. Information on TRESU’s full range of coating circulators and conditioners for high-viscosity coatings will also be available on the stand.

 

A core competency of TRESU’s ancillary portfolio is process temperature control. Since the 1980s, TRESU’s Dallas facility has been providing innovative solutions for pumping heat from printing presses. The company’s chilling systems utilise a “split system” design using a remote condenser to extract heat from the pressroom and not interfere with the printing process or place additional demands on a facility’s heating, ventilation and air conditioning system.  

 

TRESU is a leading provider of process temperature control systems and devices for managing heat generated by offset, flexo and digital printing presses. A unique feature in every process chiller from TRESU is the proactive IDMS (Internal Diagnostic Monitoring System) module. IDMS monitors the chiller and alerts the TRESU service department of performance issues, and gives customers peace of mind. 

 

Flexo printers can achieve higher speeds with TRESU’s drying technologies. High-performance drying depends on air flow and velocity, especially when water-based inks are involved. Drying speeds and efficiency have been optimised, and up to 80 per cent of the air inside the dryer – and 60 per cent of the exhaust energy - can be recycled, through TRESU’s green technology solutions.

 

Inline coating for digital packaging printing

As digital packaging converting continues to grow rapidly, TRESU works closely with digital press manufacturers, developing versatile, efficient inline coating systems to meet the demands of very short-run production. TRESU coating systems integrate with sheet-fed digital presses to apply added-value coatings and metallic embellishments to folding carton, papers and synthetic materials for pharmaceutical, cosmetics, food and beverage, promotional gift, consumer electronics packaging and commercial printing applications.

 

The TRESU iCoat 30000 is designed for use with the HP Indigo 30000 Digital Press, and the TRESU Pinta is available for Xerox iGen press users. TRESU also supplies a comprehensive range of consumables such as varnish media, tapes and sleeves, as well as cutting equipment, thereby covering every element in this coating workflow. The TRESU iCut 30000 digital cutter quickly prepares plates for localised coating situations.

 

“PRINT remains a major marketplace for all sectors of the industry, and in today’s business environment it is essential that packaging converters learn what is available to make them more efficient and competitive” said Scott Hibbs, president, TRESU Americas. “TRESU’s printing presses, ancillaries and ability to serve its customers throughout North America position it as an ideal partner for successful converters and major brands.”

On the new one-stop web-to-print service, Vanilla Reindeer (vanillareindeer.com), consumers may order premium-quality bottle cartons and rope-handled bags, in a wide range of format sizes, for numerous special occasions, in addition to matching greetings cards. The website offers delivery within 48 hours of ordering.

 

An easy-to-use interface lets customers decorate products by uploading their choice of high-definition images and creating messages, based on a wide range of colourful and appealing designs.

 

Kalas is a leading supplier of plastic packaging for horticultural and food products. Its existing manufacturing equipment comprises sheet-fed dry offset presses, lamination, cutting and creasing, and folding carton gluing.

 

Jonathan Padley, managing director of Kalas Packaging, comments: “Personalised gifts are so popular because they give us something unique - they make us feel special.  A one-of-a-kind package, marked with the recipient’s identity, is bound to be as well-appreciated. But demand has not been met because bag and box converting is too complex for ordinary printers to consider.

 

“With our long and varied converting industry experience, we already have the post-print facilities in place, perfectly suited for roped bag and box-making. The addition of the HP Indigo and TRESU digital printing and coating line, with variable data capability, means we are uniquely positioned to provide an immediate premium-quality personalised service that is certain to complement any special occasion.”

 

The HP Indigo press and integrated TRESU coater provide a single-pass printing and coating line with minimal waste and setup times for gift boxes, while bags are digitally printed then laminated near-line.

 

Featuring seven colours, the HP Indigo 30000 press can reach 97 per cent of the PANTONE® Colour gamut. The TRESU iCoat coater applies UV and waterbased coatings for a full or selective gloss, matte or velvet-touch finish. The integrated line featuring both units has a maximum speed of up to 4600 sheets per hour (3450sph in four colours), handling substrates of maximum format 750mm x 550mm in paperboard and metallised boards between 250µm and 600µm thickness.

 

The TRESU iCoat 30000 unit’s automatic chamber-cleaning and fast sleeve-change capabilities enable varnish change-overs within approximately 10 minutes. Kalas also uses the TRESU iCut 30000 digital sleeve cutter for fast, on-demand imaging of sleeves that are used on the coater.

After coating, the automatically stacked sheets are manually transported to cutting and creasing equipment nearby.   

 

Padley comments: “After closely researching the digital printing market and assessing the capabilities of the technology, we chose the HP Indigo 30000 press together with the TRESU iCoat 30000 coater because they provided the first productive solution for quality on the wide range of formats and material thicknesses needed in gift packaging. The installation of the line provides the opportunity for growth and the possibility to develop what until now has been a virtually untapped market.”

Additionally, there will also be information about the Flexo Innovator printing and converting line. Intended for mid-web paperboard applications, this press meets exacting quality demands and is capable of speeds of up to 800m/min.

 

Comprehensive chamber doctor blade programme

TRESU’s ancillary solutions, comprising chamber doctor blades and ink supply systems, provide enclosed, automatically controlled ink/coating circulation, resulting in clean print / coating reproduction, uniform ink density, reductions in material waste and makeready times, and faster production speeds.

 

Central to the performance of TRESU’s chamber doctor blade systems is the company’s unique “Pressure Control Technology”, which prevents the occurrence of microfoaming, to ensure clean, uniform print on the substrate – even for high-viscosity metallic coatings. A key feature of the technology is a long-life rubber seal system that provides an airtight enclosure, preventing leakage and enabling the pressure of the ink or coating to be maintained at consistently-high levels. A liquid barrier forms between the rotating anilox cells and the chamber, preventing any air in the cells from transferring to the coating during production. The chamber doctor blades also feature fast, safe blade exchange as standard.

 

The chamber programme includes lightweight, corrosion-resistant carbon fibre and ceramic variants. Available in widths from 185mm to beyond 6000mm, the chambers cover all flexo printing and coating applications and ink sets. There are closed-cassette chambers for label presses, and wider variations for folding carton, flexible packaging, corrugated board and tissue converting.

 

A highlight at IGAS will be the MaxiPrint Concept chamber for wide-format applications, in widths from 1600mm to 6000mm. Made from carbon fibre, and offering light weight, corrosion-resistance  and easy cleaning, the MaxiPrint features an integrated cleaning nozzle with a robustly-designed water-shot mechanism. This ensures efficient, fast cleaning of the chamber and anilox roll, with minimal water loss. Featuring TRESU’s patented seal system, MaxiPrint prevents leakage and interaction of the chamber contents with the atmosphere. It includes the TRESU P-Line pneumatic clamping system for fast, safe blade exchange within just two minutes.

 

Also on show will be the new SAVEink chamber for water-based and UV-curable narrow- web applications up to 800mm wide. The larger-volume chamber profile acts like an integrated ink reservoir, eliminating the need for a connected pumping system.  The chamber is easily locked into place, and is removed without ink spillage in seconds. The SAVEink chamber also features TRESU’s seal system and E-Line quick-blade-change system, which offer minimum press downtime for press widths up to 800mm.

 

Supply systems for flexo inks and coating media

TRESU also provides supply systems for low and high-viscosity flexo inks and coatings. Where a relatively-low pressure is required, the F10 iCon ink supply system regulates ink flow, pressure, and viscosity, ensuring a constant, accurate ink density on the printed substrate, without any air contamination. This energy-efficient system also provides thorough automatic cleaning, achieving a complete ink change cycle in between five and 15 minutes. It is ideal for common impression (CI) print, stack and line configurations, and can be retrofitted as an upgrade to existing equipment.  Additionally, TRESU offers a range of coating circulators and conditioners for high-viscosity coatings, where high pressure is needed. Conditioners include the TRESU L30i for UV and water-based media; the TRESU L10i AQ for water-based media; and the TRESU L10i UV for UV coatings. The TRESU XL5i coating circulator is designed for both UV and water-based coatings.

 

Based in Osaka, TRESU Japan --  part of TRESU’s global support network --  provides Japanese customers with a local point of contact for sales, technical support, installations and retrofitting programmes.    

 

Tetsuo Shikai, managing director, TRESU Japan, comments: “As well the latest coating solutions for high-quality offset, we can also offer our latest technologies to the flexo print  industries as well. Thanks to innovations at all stages of the workflow, high-quality flexo technology today offers a standard of definition, colour consistency, and sharpness that is indistinguishable from other printing processes. With TRESU’s chamber doctor blades and ink supply systems, flexo printers are well-placed to meet brand owners’ stringent quality expectations, and eliminate waste and waiting time from the workflow. This brings significant savings, and the ability to offer greater service flexibility -- such as shorter production volumes -- while maintaining margins. A visit to the TRESU stand at IGAS 2018 provides an opportunity to learn about these advantages at first hand.”

 

Flexo Innovator printing line for high print quality, fast job changes and sustainability

Product data and animations of TRESU’s complete printing lines and coating systems will also be featured on the stand. Another highlight at IGAS will be the Flexo Innovator press, for high-value packaging applications, which combines outstanding print quality, high production speeds, fast job changes, sustainable print, and an ergonomic design. Available in several widths between 670mm and 1700mm, the Flexo Innovator is a custom-configured, multi-process, inline printing and converting press for folding cartonboard, paper, laminates and metallic substrates.

 

TRESU Flexo Innovator provides an efficient, single-pass alternative to labour-intensive central-impression printing, enabling the integration of water-based, solvent, and UV-curable inks, as well as multiple high-end complementary processes such as reverse printing, direct/reverse gravure coating, inkjet print, and cold-foil lamination and converting.

 

With high-speed unit-to-unit air drying, and automated ink supply and sleeve systems, the press provides a stable, efficient print platform at speeds of up to 800 metres per minute. Sustainability is central to the design of the Flexo Innovator.  Its many features ensuring reduced waste, energy usage and emissions reflect TRESU’s commitment to minimising the environmental footprint of flexographic print.

 

Efficient energy consumption is achieved with a unique gas-heating solution and a software design where servo motors run at relatively low power. Drying units recycle a high proportion of the air inside the dryer and, from the exhausted air, much of the energy is recycled by means of the central heat exchange module. The drying system’s temperature and air nozzle speed can be adjusted to the requirements of the job, avoiding substrate overheating or the need for excessive chilling. Chilling systems safely extract heat from the press to external condensers, which can return the energy to the incoming cold fresh air. Web-changing systems, plus automated register and colour controls, minimise material waste in the start-up phase, while the F10 iCon ink supply system optimises ink return for reuse at the end of a print job. The Flexo Innovator’s ability to match the quality of gravure also gives converters a cleaner, water-based alternative to solvent ink usage for reproducing added-value metallic and high-definition effects.

 

TRESU’s ancillary solutions, such as enclosed chambers and ink supply systems and automated press controls, ensure uniform quality, minimal manual intervention, and fast automatic ink changes, and the resultant shorter makeready times optimise press uptime, especially for shorter print runs.

 

Integrated coating systems for digital printing

At the stand, there will also be presentations about TRESU’s coating workflow for integration with digital printing lines. TRESU coating systems integrate with sheet-fed digital presses to apply added-value coatings and metallic embellishments to folding carton, papers and synthetic materials. Applying full-surface or spot coatings, the systems provide the essential link in a productive single-pass digital printing and converting solution for pharmaceutical, cosmetics, food and beverage, promotional gifts, consumer electronics packaging and commercial printing applications.

 

TRESU iCoat single and dual coaters are available for HP Indigo presses; TRESU Pinta is available for Xerox iGen presses. The coaters perform at maximum speeds equivalent to those of the press. Fast sleeve changeovers and automatic chamber cleaning bring setup times to within five minutes.

Additionally, TRESU supplies a comprehensive range of consumables such as varnish media, tapes and sleeves, as well as cutting equipment, thereby covering every element in this coating workflow. The TRESU iCut 30000 digital cutter provides an instant means of preparing plates for localised coating situations.

 

TRESU’s digital coating systems are helping a rapidly growing number of printers benefit from inline gloss and matte coating of folding cartons and other products. With fast, efficient job changeovers, TRESU’s digital coaters enable printers to have a robust, highly efficient, value-adding solution for today’s packaging demands.

Established in 1977, Aspen Paper Products has become one of the United States’ leading manufacturers of table top paper products including plates, bowls and lunch bags, supplying retail, wholesale and quick service restaurant markets nationally. Its Kansas City headquarters employs over 500 people and produces 400 tons of paper products per day.

 

Changing social trends in the 1990s transformed the market with “time-poor” consumers switching to disposable plates for home meals. Even with the factory’s three existing flexo presses running three shifts, five days a week - and sometimes seven - Aspen was struggling to provide printed material to the converting lines. By 2016, it was clear that a new press was needed. 

 

Aspen met with a number of press manufacturers but made the decision to invest in the TRESU Flexo Innovator press after seeing demonstrations of the printing and drying systems at the drupa fair that year.

 

Troy Walls, general manager, Aspen Paper Products, Inc., explained what the company was looking for:

First, high output and quick setup times were crucial to our competitiveness. We need high speed to supply our largest superstore customers that place orders of up to 500 rolls for their major distribution centres. Second, was substrate versatility, as we work with a wide variety of paper thicknesses, from 12 to 26-point [approximately 270g/m2 to ~570g/m2]. Third, we were determined to install a line configuration, because it allows the operators to be on the ground at all times and work quick and safely. With our common impression presses, we were losing time because we needed ladders and hoists to gain access and exchange equipment.”

 

The Flexo Innovator press at Aspen features nine colours, with CMYK in the first four positions, followed by spot colour positions, and units to apply seal-coating for waterproofing and grease resistance, as well as the option to apply reverse-sided coating. Aspen uses water-based inks only, the press features energy-efficient unit-to-unit drying systems. The chilling system, built by TRESU, manages all the process temperature control requirements on the Flexo Innovator to tightly controlled specifications.

 

We specifid more stations than we needed for any printing job to save makeready time, especially when spot colours and ink changes are needed. Idle units can be prepared for the next job while the press is in production. Thanks to the automated ink supply and controls, job changeovers can occur within a few minutes – significantly faster than on our other presses,” Walls said.    

 

Inline double-sided printing gives Aspen further production efficiencies:

The Flexo Innovator’s two-sided printing and accurate registration allows us to produce the printed product with backside coating in a single pass and restrict the application of coating to the desired location,” he continued.

 

The Flexo Innovator features TRESU’s enclosed chamber doctor blade systems with F10 iCon ink supply system which automatically ensure ink supply at constant viscosity, flow-rate and pressure. The chamber doctor blade systems feature a rubber seal system to prevent leakage, while the doctor blades are positioned to avoid anilox wear and stop air entering the chamber. This means the Flexo Innovator can run at top speeds and assure uniform ink coverage as well as consistent ink density throughout the print run.  

 

TRESU’s enclosed ink supply systems are definitely the most advanced we have had. The automatic wash-up system makes ink changes fast and thorough without operator involvement. We are saving ink at the end of each job as almost all the ink is returned from the chamber for reuse.”

 

The enclosed ink supply system – combined with unit-to-unit air drying – provides the stability to the Flexo Innovator, enabling Aspen to achieve consistent quality when printing at up to 2000fpm (approximately 600m/min), significantly faster than existing machines at its plants. The fastest speeds are achieved with 60-inch (1.5m) rolls of material that is 20-point (350g/m2) thick, which take three and a half minutes to print.

 

With its fast setup times, and stability at high speeds, TRESU’s Flexo Innovator enables us to offer rapid response times for large and small volume orders, without compromising on productivity. With the big accounts, we may run 40 rolls at a time, then jump out to run a few rolls for a discount store, then return to the large order. This kind of flexibility is essential to maintaining customer satisfaction as well as margins,” Walls said.

“The Flexo Innovator is a long-term investment, to assist us to realise our long-term growth strategy. The Flexo Innovator is a step-change in productivity at Aspen, and that brings new challenges as well as opportunities. We are very satisfied with the collaboration and the progress makes us well positioned to continue with the next stage of our growth phase at our Kansas City facility,” Walls concluded.

The TRESU stand highlighted the global debut of the SAVEink chamber doctor blade for narrow-web applications, the self-cleaning carbon fibre MaxiPrint chamber for wider web situations, and information about the Flexo Innovator high-speed printing line, and TRESU iCoat 30000 for digital folding carton printing lines.

 

TRESU’s programme of chambers, available in widths from 185mm to over six metres, together with its F10 iCon ink supply system, provide a complete solution for controlled, enclosed ink supply for almost all flexo printing situations. 

 

TRESU Italy, the Milan-based subsidiary, supports a growing Italian customer base using its ancillary solutions for regulating ink supply,  coordinating retrofitting programmes, providing technical consultancy, and supplying new presses.

 

Several leading Italian press manufacturers include TRESU chamber doctor blades for advanced-specification models. TRESU chamber doctor blades also feature on flexo units of more than 400 offset presses in the country to apply a post-print protective coating or a gloss finish to enhance graphics, mainly for cartons.  

 

Gianni Amendola, office manager, TRESU Italy, comments: “A large proportion of our label and packaging customers supply the cosmetics and wine industries where image is of special importance, and there can be no compromise in quality. As converters recognise the impact that ink regulation has on profitability – especially with the growth of shorter run-lengths – the interest in TRESU’s ancillary solution grows, as they are a proven way of meeting stringent targets, driving down costs, and raising productivity.”

 

The savings begin with cutting ink waste through leakage and contamination. TRESU’s chamber doctor blades feature a patented seal system that prevents leaks and interaction of the chamber contents with the atmosphere. The enclosure is completed with precise blade positioning that stops air entering the anilox cells, automatically keeping pressure and flow rate at desired levels. Air contamination is prevented, and foam-free transfer of ink / coating is achieved at fast speeds. Even laydowns across the substrate and consistently high ink density levels are achieved. Pneumatic clamping systems ensure fast, safe blade changes within two minutes. For easier handling, light-weight corrosion-resistant carbon-fibre chambers are available for wider widths, in addition to ceramic or aluminium varieties.

 

The new SAVEink chamber for widths up to 800mm made its global debut at the show, and attracted much interest. The chamber has a preset doctor blade for precise application control, and locks into place in seconds, and is sealed to avoid risk of spilling or ink contamination.

 

The MaxiPrint Concept for wide format applications is available in widths of 1600mm to 6000mm, and features an integrated cleaning nozzle with a robustly designed water-shot mechanism to ensure efficient cleaning of the chamber and anilox roll in a short time. The low pressure shot mechanism ensures minimal water loss during cleaning.

 

Complementing the chamber doctor blade programme is TRESU’s F10 iCon for safe, stable and controlled ink circulation. Flow rate, ink pressure and viscosity are automated, avoiding the labour-intensive, time-consuming task of monitoring ink flow.

 

Amendola says: “Converters are reporting six-figure savings annually through the combination of automation, reduced ink waste and increased productivity. Automatic ink return and cleaning on all units occurs simultaneously, thoroughly, in five to ten minutes. Manual intervention is limited and presses can run at faster speeds. The ability to retrofit these chambers means that these benefits are available to a very large number of Italian converters.”

 

TRESU Italy’s technical team, with support from the company’s Danish headquarters, also provide retrofitting, bringing existing presses that in some cases can be more than 20 years old to the latest standards of productivity. Recently, the service team installed the MaxiPrint Concept System on a six-colour 2.6-metre wide common impression press at a major Veneto-based containerboard manufacturer in only 10 days. TRESU is currently installing three 3.2m-wide presses with a total of 20 printing units at a Lucca-based original equipment manufacturer serving the tissue market.  With local expertise and support from the Milan office, long-term relationships are built along with programmes of continuous development and optimal performance.

 

Information about TRESU’s Flexo Innovator printing line and iCoat 30000 for digital folding carton printing lines was also available on the PRINT4ALL stand. The Flexo Innovator is mid-web press has proven to offer high quality, fast setup times, ergonomic operation, production flexibility and industry-leading speeds of up to 800m/min for paperboard packaging applications. For inline coating, the iCoat 30000 offers flood and spot coating and varnishing for digitally printed sheet-fed folding carton production with the HP Indigo 30000 Digital Press.

tesa Softprint® Performance Check on TRESU Flexo Innovator Press

Short text:

The liquid packaging board industry is greatly affected by changes within our modern socio-economic environment. As such, the European Union’s August 2017 report expressed that one third (33.1 %) of all households within the European Union in 2016 were single-person households, a statistic which corresponds to the market trend regarding smaller packaging.

This, combined with an exploding demand for new flavors in the convenience food and beverages sector has seen the landscape of the liquid packaging board industry enter into a state of creative flux.


What is the impact for liquid packaging board printers?  

In order to increase the visual effects of smaller pack sizes so that they might attract more consumers, packaging designers are working on more challenging and creative design elements, all of which lead to higher print quality requirements. Furthermore, the increasing number of unique and complicated product designs pushes the industry to re-think existing production methods. This is vital in giving producers the opportunity to react to changing conditions and remain efficient and competitive in the market.

 

Proof of performance on the TRESU Flexo Innovator press 

To prove the influence on print quality tesa often test the tesa Softprint® plate mounting tape on-site at industry leading print manufacturers. One of the latest tests was performed in the technical center of TRESU Group in Denmark. The goal was to evaluate the impact on print quality when using different foam hardness levels to print on paper carton board.

 

The trial was conducted on the TRESU Flexo Innovator press with a 6 color (CMYK + 2 spot colors) test form. This printing press is designed to print on a variety of paper board material and thanks to their innovative machine concept, fast job changes with low waste rates can be achieved.

 

The outcome of the print test

The general belief regarding foam hardness is that plate mounting tapes with harder foams are recommended for solid motifs while plate mounting tapes with softer foams are recommended for screen motifs.

 

Foam_1000

 

During the trial we tested a four main tesa Softprint® plate mounting tape hardness levels under identical conditions. For the printing plate, we used a 1,14 mm Kodak NX plate with 60L/cm and an anilox roller with 400L/cm and 4,6 cm³/m².

 

The evaluation of the samples showed that the SOFT Foam (red color code) produced the best results. Even on solid prints, low dot gain and equal ink laydown without pin-holing effect can be achieved.

Conclusion

The evaluation of the print samples produced results that slightly differed from the expected theoretical outcome. The reasons for this are mainly related to the paper substrate which behaves completely differently to materials such as film in the flexible packaging industry. Equally, the printing plate technology used (Kodak NX) has micro structures (or enhanced surface technologies) which provide a particularly high ink transfer to the substrate. These factors have to be considered when selecting the appropriate anilox roller and plate mounting tape foam hardness.

 

If each of these disparate components is perfectly coordinated then the whole process is significantly simplified, leading to a more streamlined and efficient process, and ultimately higher print quality.

 

If you want to know more about our tesa Softprint® products or TRESU Group flexo printing presses please contact your responsible tesa and TRESU sales representative.

 

The secret of the tesa foam plate mounting tapes:

To provide excellent print quality, tesa Softprint® plate mounting tapes are equipped with a closed cell PE foam which offers excellent resilience and cushioning properties throughout the press run. In addition to this the foam in our smart tape production process is handled with the utmost care to avoid any mechanical stress, resulting in more intact cells for better cushioning and resilience over time.

At the show, there will also be information about TRESU’s Flexo Innovator printing line, a mid-web press that has proven to offer high quality, fast setup times, ergonomic operation and industry-leading speeds of up to 800m/min for paperboard packaging applications.
 

Chamber doctor blades for all flexo print widths

Operational products featured on the stand are the latest chamber doctor blade solutions to ensure optimum performance, ink use, and ink preservation. The range includes the light weight CFC chamber with carbon fibre ink-repellent surface for high corrosion resistance; the Ceraflex chamber with ceramic surfaces; the new SAVEink chamber for narrow web applications, and FlexiPrint Easy chambers, for flexible packaging. Each of these solutions has been designed for specific applications and challenges.
 

The SAVEink chamber, making its global debut at PRINT4ALL, is light for fast and frequent job or ink changes. The SAVEink chamber has a preset doctor blade and offers precise application control for press widths up to 800mm.The chamber easily locks into place and is sealed so there is no risk of spilling, or ink contamination.
 

Also on show for the first time will be the MaxiPrint Concept for wide format applications. Available in widths of 1600mm to 6000mm, the chamber features an integrated cleaning nozzle with a robustly designed water-shot mechanism to ensure efficient cleaning of the chamber and anilox roll in a short time. The low pressure shot mechanism ensures minimal water loss during cleaning. Featuring TRESU’s patented seal system MaxiPrint prevents leakage and interaction of the chamber contents with the atmosphere. The enclosed environment, resulting from the seal and precise blade positioning, ensures pressure and flow rate are maintained at desired levels without manual intervention. Air contamination is prevented, and the foam-free transfer of ink / coating directly to the anilox cells is enabled at fast speeds. The TRESU P-Line pneumatic clamping system also ensures fast, safe blade exchange within two minutes.
 

F10 iCon automatically regulates ink supply

The F10 iCon is a lean, innovative solution for safe, stable and controlled ink circulation. Using the patented TRESU ViscoFlow, the F10 iCon automatically adjusts flow, ink pressure and viscosity, providing complete ink process control and outstanding print quality.

Ideal for common impression (CI) printing machines with TRESU chambers, stack presses and other press configurations, the F10 iCon is retrofittable as an upgrade of your existing equipment. The F10 iCon can be used with numerous substrates, including plastic, foil, film, carton board and paper.  
 

Flexo Innovator printing line for high print quality, fast job changes and sustainability

Information and animations of TRESU’s complete printing lines and coating systems will also be presented on the stand. A highlight will be the Flexo Innovator press, for high-value packaging applications, combining outstanding print quality, high speed, fast job changes, sustainable printing and ergonomic design. Available in several widths between 670mm and 1700mm, the Flexo Innovator is a custom-configured multi-process, inline printing and converting press for folding carton board, paper, laminates and metallic substrates.
 

The TRESU Flexo Innovator provides an efficient, single-pass alternative to labour-intensive central-impression printing, enabling the integration of water-based, solvent and UV-curable inks, plus multiple high-end complementary processes such as reverse printing, direct/reverse gravure coating, inkjet, cold-foil lamination and converting. With high-speed unit-to-unit air drying, automated ink supply and sleeve systems, the press provides a stable, efficient printing platform at speeds of up to 800 metres per minute. Sustainability is central to the design of the Flexo Innovator, with a host of features that reduce waste, energy usage and emissions reflecting TRESU’s commitment to minimising the environmental footprint of flexographic print.

 

Efficient energy consumption is achieved with a unique gas heating solution and a software design where servo motors run with relatively low power. Drying units recycle a high proportion of air inside the dryer and, from the exhausted air, a major part of the energy is recycled by means of the central heat exchange module. The drying system’s temperature and air nozzle speed can be adjusted to the requirements of the job, avoiding overheating of the substrate or the need for excessive chilling. Chilling systems safely extract heat from the press to external condensers that can return the energy to the incoming cold fresh air. Web-changing systems, plus automated register and colour controls, minimise material waste in the start-up phase, while the F10 iCon ink supply system maximises returns of ink for reuse after production. Furthermore, the Flexo Innovator’s ability to match the quality of gravure gives converters a cleaner alternative for reproducing added-value metallic and high-definition effects with water-based flexo inks, instead of solvent inks.

 

TRESU’s ancillary solutions, such as enclosed chambers and ink supply systems, plus automated press controls, ensure uniform quality, minimal manual intervention and automatic ink changes in minutes. Shorter makeready times, to optimise uptime, especially when performing shorter runs.

 

Integrated coating systems for digital printing

At the stand, there will also be presentations about TRESU’s coating workflow for integration with digital printing lines. TRESU coating systems integrate with sheet-fed digital presses to apply added-value coatings and metallic embellishments to folding carton, papers and synthetic materials. Applying full-surface or spot coatings, the systems provide the essential link in a productive single-pass digital printing and converting solution for pharmaceutical, cosmetics, food and beverage, promotional gifts, consumer electronics packaging and commercial printing applications.

 

TRESU iCoat single and dual coaters are available for HP Indigo presses; TRESU Pinta is available for Xerox iGen presses. The coaters perform at maximum speeds equivalent to those of the press. Fast sleeve changeovers and automatic chamber cleaning bring setup times to within five minutes.
 

Additionally, TRESU supplies a comprehensive range of consumables such as varnish media, tapes and sleeves, as well as cutting equipment, thereby covering every element in this coating workflow. The TRESU iCut 30000 digital cutter provides an instant means of preparing plates for localised coating situations.

 

TRESU’s digital coating systems are helping a rapidly growing number of printers benefit from inline gloss and matte coating of folding cartons and other products. With fast, efficient job changeovers, TRESU’s digital coaters enable printers to have a robust, highly efficient, value-adding solution for today’s packaging demands.

 

Facing market and economic challenges

Knowing what equipment to invest in, and when, is challenging for converters. TRESU can help companies identify where their workflow can be improved, and what services can contribute to their value proposition.

 

“While there has been significant growth in some areas of print in recent years, companies are often reluctant to initiate capital investment in new presses,” said Gianni Amendola, branch office manager, TRESU Italy. “This is where modest investment in value-adding and cost-cutting ancillaries can help to improve print quality, make converters leaner, more competitive, and more profitable.
 

“The TRESU ancillaries shown at PRINT4ALL can be retrofitted and integrated into existing workflows to deliver results that go straight to the bottom line,” Amendola concluded.

Creating an optimum coating solution for digital folding cartons

The arguments for investing in digital folding carton production are also compelling. Demands for shorter runs, faster turnaround, and savings on logistics and warehousing mean that all folding carton converters should be actively investigating adding a digital capability.
 

Digital print quality has ceased to be an issue, and accurate colour – even for special corporate and brand colours – can be reliably and consistently achieved. The ability to match and integrate digitally printed materials with those printed conventionally is a further benefit. Additionally, the ability to respond effectively to late production instructions, last minute text and design changes and to cutting waste and lowering the environmental footprint are yet more persuasive reasons for investing in digital.

The whole picture

To replicate the quality associated with conventional processes and offer the flexibility of short lead times and control costs also, a digital folding carton workflow must offer printing and coating in a single pass.
 

Digital technologies offer unparalleled flexibility and versatility with the ability to quickly and easily switch between jobs, so an in-line coating solution needs to be able to respond accordingly. To provide the level of acceptable performance, a coater for digital print needs to provide pre-treatment, flood, spot and fine line coating and effective drying  of substrates ranging from 180g/m2 to 500g/m2 (121.6lb to 337.8lb) at full press speeds (c. 5,000 sheets per hour). An ability to handle both water-based and UV-curable varnishes is a further advantage. And, of course, the register must be spot on.

Using a modular approach, an in-line coating solution for digital carton presses can deliver all of these things.

 

Beginning with the coating unit, the use of a simple three cylinder solution facilitates high speed operation. With the anilox, printing plate and impression cylinder all using sleeve technology, changes can be made extremely quickly: less than a minute to change the print cylinder, and less than five to change all three. This ensures maximum productive press time which can improve profitability and competitiveness.

Using sleeves has advantages beyond quick changes. Being a sleeve means that there is no gap on the cylinder, and no need for gripping mechanisms that can malfunction or collect dirt. However, the biggest factor is that sleeves roll smoothly and won’t develop cylinder bounce which can limit running speeds and cause mis-registration.
 

One problem that can arise regardless of whether a plate or a sleeve is used is a bump caused by the cylinder first touching the plate. Systems that have a small recesses in the plate sleeve that virtually eliminates this phenomenon, enabling precise registration at speed – and perfect registration is essential.
 

Since digital presses generate little or no start-up waste, printing extra sheets cuts into margins, so finding a system that can achieve register quickly is an important consideration. Generally speaking, the simpler the system, the better; coaters using mechanical alignment are accurate and reliable. They are easily set and don’t require tweaking or monitoring during the run.
 

Adding value and calculating cost

Apart from adding protection to cartons, matt, gloss and spot varnishes add value. This is even more true of digital packaging which can add value when used for limited and special editions, or employ variable data printing for track and trace, security, localisation or personalisation. Applications including luxury goods, cosmetics, chocolates, and food and drink all have their perceived value enhanced with creative coating and varnishing.

An ability to “double coat” in a single pass, using both matt and gloss varnishes to create a highly distinctive look and feel, is a powerful capability, especially when used in high value applications such as those mentioned. Today’s single and twin coating systems allow you to achieve an identical ‘look and feel’ quality in digital, to that which is possible in offset. 
 

When discussing digital folding carton printing and its enhancements, the subject of cost usually arises. While digital printing is now benefitting from economies of scale, old perceptions, usually focused on unit-cost, still inhibit its adoption.But the old paradigm of unit-cost no longer applies: when thinking digitally, it is the total end-to-end cost that matters. Printing only what you want, when (and often where) you want it, and getting it to market quickly is what digital printing is about, and using this technology in tandem with an integrated coating solution is now possible.

Suited for wide-web and corrugated flexo applications, the concept offers corrosion-resistance; fast, automatic internal cleaning; improved quality consistency and reduced ink loss. 

The TRESU chamber offers significantly faster emptying performance compared with alternative chambers, because the ink or coating fluid is evacuated through both the chamber’s inlet and outlet. The fast drainage of the chamber, further assisted by rounded internal surfaces, facilitates thorough cleaning: the subsequent washing process can begin before any residue can dry on the anilox roll or inside the chamber.  The ink change and cleaning cycle is typically completed within approximately 3-5 minutes. 

Available in widths of 1000mm to 6000mm, the chamber features an integrated cleaning nozzle with a robustly designed water-shot mechanism, to ensure efficient cleaning of the chamber and anilox roll in a short time. The shot mechanism maintains a low pressure, limiting water loss during the cleaning cycle. 

The MaxiPrint Concept features TRESU’s patented seal system that prevents leakage and interaction of the chamber contents with the atmosphere. The enclosed environment, resulting from the seal and precise blade positioning, ensures that pressure and flow rate are maintained at desired levels without manual intervention. This stops air contaminating the chamber and results in perfect transfer of ink/coating directly to the anilox cells, also at fast speeds. Watch the NEW TRESU MaxiPrint animation here

“Advanced ancillary systems provide the solution for automatically controlling ink supply to the flexo press, and the impact they can have on performance can be dramatic,” said Mario Busshoff, co-owner and president, Innova Flexo Products. “Ancillary products like TRESU’s F10 iCon controlled ink supply system, MaxiPrint Concept ink supply and cleaning system and chamber doctor blades can be installed on new presses or retrofitted to existing machines, making them more competitive and extending their service.”
 

TRESU’s ancillary systems reduce ink waste and consumption while contributing to improved print quality. They control pressure, viscosity and flow rates, thereby eliminating contamination and manual intervention. Shorter set-up times and tighter tolerances add to the incremental benefits that contribute to overall time-saving. The ink supply system’s ability to recover ink provides potential for significant savings. Presses can also run faster without loss of print quality.
 

TRESU chamber doctor blades, made from carbon fibre, ceramic material and aluminium, together with the company’s ink supply systems, are available for all flexo printing and coating applications, including labels, paperboard, flexible packaging, and specialist situations featuring web widths above six metres.
 

Speaking for TRESU Ancillary, Henrik Kristensen, vice-president, TRESU Ancillary, said: “It is a great asset to have the experienced team at Innova Flexo Products representing us. There is no substitute for local knowledge, language support, and understanding of market conditions. The appointment is important for those reasons, and it also strengthens our commitment to the Spanish and Portuguese markets.”

Chambers are air-tight and prevent leakage, thanks to TRESU’s patented seals, and can be installed or removed safely in five seconds without the risk of spilling ink. To introduce the unit to its mounting, the operator locks it to the anilox roll, and rotates it from a six-o’clock to a nine-o’clock position. Removal reverses the process.

 

Doctor blades are in a pre-set position, and there is no need for further adjustment. The pre-set position ensures optimal anilox contact with minimal wear. An automatic indicator shows when blade replacement is necessary, so time is not wasted on unnecessary checks.

 

The chamber can hold 250ml – 2000ml of ink making it ideal for application of normal and spot colours, as well as high ink transfer printing. Ink may be added manually without stopping the press, giving the system flexibility for long and short run production.

 

Since the chambers are sealed, there is no risk of ink contamination and optimal pressure is maintained, to ensure foam-free printing and an even ink coverage across the web. The chamber maintains precise inking even at the high speeds demanded by narrow-web printers. Available in widths up to 800mm, the TRESU FlexiPrint Reservoir SAVEink chamber may be fitted to almost any narrow web press.

 

For those using manual filling, the chambers can be removed and sealed so that ink can be reused. As the unit features a single compartment, manual cleaning is fast and easy.

 

Printers using an optional pump system have the advantage of precise flow control, as well as the ability to return unused ink to the bucket. Complete flushing and anilox cleaning to enable colour changes is also possible with pump systems.

 

Henrik Kristensen, vice president, TRESU Ancillary, comments: “With shorter runs and faster turnarounds, label converters are under increased competitive pressure to eliminate waste. TRESU’s single-component SAVEink system makes an attractive option for an efficient label printing workflow, with its fast setup times, minimal maintenance requirements and capability for consistent quality at high speed. With a short return on investment, the benefits of our chamber doctor blades are a viable and value-adding alternative to investing in a new press.”

With advanced drying, curing and ink supply systems, it can include numerous colour stations and finishing processes for achieving distinctive, high impact designs in a single pass –at speeds up to 800 metres per minute. Available in several widths and offering fast setup times, Flexo Innovator is competitive for both short and long printing runs. 

 

Packaging converters are facing challenges to meet higher quality and service standards. Brand owners want packaging with more added-value finishing techniques for increased self-presence to stand out and sell on the retail shelf. At the same time, increased choices, localisation and brand extension result in shorter run lengths.  Additionally, in food and beverage sectors, we see an abundance of new niche players offering specialist products like craft beers, luxury coffee, tea, chocolate, and “farm produced” cheese and yoghurt. At the same time, major global brands retain their positions – and long run demands.

 

These trends suggest that converters need to offer more creative, sophisticated packaging solutions to give brands a distinctive look. Increasing cost and time pressure requires the production efficiency achievable in a single pass. Moreover, converters need the flexibility to change jobs quickly, to cater for both long and short run volumes.

 

Increasingly, packaging printers are telling us that they have to print up to 14 jobs in one eight-hour shift as well as occasional runs up to 160 rolls, lasting three days.  

 

Flexo meets the most demanding quality expectations: it is capable of definitions up to 180lpi (70l/cm), which, for the consumer, is indistinguishable from offset or gravure. The thick ink coverage of flexo lays down rich solid colours, as well as contrasting varnishes in a single pass, achieving quality reproduction on economical substrates.

 

Inline flexo also offers the advantages of modularity and the ability to combine many processes and ink sets and efficient drying. Printing lines like the Flexo Innovator can be configured with any number of colour and coating stations, as well as complementary processes. These can include reverse printing, coating, digital and rotogravure processes, and different ink sets. Inline presses can also be retrofitted with extra modules as needs change. 

 

Hybrid Flexo

Line configurations allow greater web distance between printing stations for better control and faster speeds during drying and curing. Hybrid flexo printing, combining water-based UV-curable and solvent ink printing stations, is growing in popularity, as it allows a wider range of printed and coating effects for increased product differentiation.

 

Drying Systems

Inline flexo is beneficial for fast water-based printing because a longer web path between printing stations is possible, resulting in cleaner colour printing. The Flexo Innovator’s drying systems offer efficient fast air flow and high velocity rather than temperature. At TRESU, we have converted gravure and direct-reverse gravure jobs to flexo within fifteen minutes, thanks in part to the performance of the drying and curing systems.  

Additional UV-flexo units for adding a high gloss or matte varnish, for high-end packaging, not only provide reflectivity, but can create a velvet ‘soft touch’ effect. Using both varnish types in combination provides a contrast to make specific features stand out. UV-curing in these situations is a productive alternative to water-based inks that may require excessive ink coverage.


Stable printing with coating at maximum speeds

One of the strongest advantages of inline flexo is speed, which is significantly faster than sheet-fed offset. Speed optimisation depends on an automated and enclosed ink supply and servo drives, sleeve systems that eliminate bouncing, automated register controls, tightly regulated web tension and efficient drying systems. These features can be included in the latest presses, ensuring stability and quality consistency, at up to 600m/min, and sometimes even 800m/min.

 

The press manufacturer will look carefully at the converter’s job mix so that the optimum press configuration can be devised. The right choice offers a return on investment that should continue for 20 years or more.

The F10 iCon supplies precise volumes of ink, ranging from 5 to 30 litres / minute, at constant, predetermined stroke frequencies. The supply system maintains optimum ink pressure in the chamber system to ensure clean print quality and accurate ink densities are achieved, consistently throughout the printing run, at speeds up to over 600m/min.

 

Furthermore, the supply system also assures an accurate way of returning inks to the bucket and fast, thorough chamber cleaning, without manual intervention. A typical cleaning cycle is complete within a matter of minutes, resulting in up to 90 percent of the ink or coating medium remaining in the press’s chamber systems returning to the bucket after production. This generates ink savings of as much as 19 litres per printing station after each job. The F10 iCon’s specially developed software reduces setup times further by storing each job’s ink recipe information, such as viscosity, flow-rate and pressure levels, thus eliminating the need for data re-entry when repeat jobs are performed.

In response to demand for dramatically shorter packaging run-lengths in the food and personal healthcare sectors, folding carton converter Qualvis Print & Packaging, of Leicester, UK, has moved into digital production with major investments in printing, coating and finishing equipment. With two digital printing and integrated folding carton coating lines from Xerox and TRESU, Qualvis is offering an efficient on-demand service with short runs, unique prints and lead-times of between six and 10 days.

 

Installed in early 2017 in a dedicated clean room, two printing and coating lines provide personalised packaging, multiple brand and language variations, as well as market testing samples. With minimal makeready costs, the production lines are providing a cost-effective source of quality packaging to start-up companies such as farms and home delivery providers, that in many cases are seeking a print run of only 100 cartons. Additionally, customers have benefited from reduced stockholding and material waste, and reduced chance of stock-outs.

 

Each production line features a sheet-fed Xerox iGen digital press, integrated with a TRESU Pinta flexo coater, providing a single-pass package printing solution with speeds of up to 2500 sheets per hour, overseen by only one operator. One line features the iGen5, featuring CMYK plus a station for blue, green or orange, allowing the matching of up to 93 per cent of the Pantone colours; the other features the iGen4, with four process stations but the same levels of speed, automation and quality, with maximum resolutions of 2400 x 2400dpi. The iGen 4 line includes a CP Bourg dual feeder, making dual-sided coating possible. After coating on each line’s TRESU Pinta, the automatically stacked sheets, of sizes up to 364 x 660mm, are wheeled to a KAMA DC76 cutting and creasing system nearby.

 

“In the last decade we have seen average packaging print runs reduce by over half to about 8,000 sheets,” explains Jason Short, Qualvis’s managing director. “The make-ready times in litho mean we could not fulfil the growing need for shorter runs and maintain the machine uptime critical for success. With practically no setup times, a digital investment would clearly enable us to offer the variety, responsiveness and flexibility demanded by the market, and critical to creating value.
 

“The two Xerox iGen presses combined with the TRESU Pinta coaters give us the combination of sharp quality, productivity and reliability to compete in these short-run markets. And, with two lines, we have the back-up to ensure the most demanding delivery times, common for foods, are met on time,” Short continued.
 

Coating is a vital process that adds impact and aesthetic appeal to the package. The Pinta coater uses food-safe varnish media, including water-based matt, gloss and soft-touch, as well as UV-gloss, specially formulated by TRESU. The large gamut of the Xerox iGen 5, combined with the Pinta’s ability to create a wide range of finishes, means Qualvis can achieve an indistinguishable look to litho on the vast majority of its jobs.

The digital investment at Qualvis complements a litho operation centred around a seven-colour KBA Rapida 106 and a six-colour Heidelberg 6LX Speedmaster.
 

The digital lines run one shift per day, and production schedules can vary heavily. Some shifts can be devoted to a single run, whereas others may comprise as many as ten jobs. Digital printing has grown quickly and already represents about 10 per cent of Qualvis’s turnover.

The introduction of the enclosed or ‘chamber’ doctor blade, generally a standard feature of new flexo presses today, was a landmark in flexo performance. They make it possible to achieve a uniform, unblemished ink transfer at higher speeds. Furthermore, they form an essential part of a lean manufacturing workflow, reducing ink consumption, manual intervention and setup times. As a prevention against leakage and emission of volatile organic compounds, they enable environmental compliance and safe, clean working conditions. 

 

Creating the closed-loop system that allows flow control and prevents leakage depends on correct positioning of the blade, secure sealing of the chamber walls and a supply system.

 

In an enclosed system with twin blades, the blades are set apart at a specific distance and angle. The reverse-angle blade meters the ink, while the trailing blade keeps the ink in the chamber. Positioning is crucial, not only to prevent air entering and ink escaping, but to prevent wear of the blade.  Precise positioning the blade by the ancillary provider at the optimum angle, at the anilox roller, minimises blade wear, reducing maintenance costs. An essential feature is safe, fast blade exchange. A clamp allows the slotting of doctor blades into position, and easy release, keeping changeover times as low as one minute.
 

A seal system forms a perfect airtight closure and stops ink leakage from between the anilox roll and the chamber. Constant pressure is maintained throughout the printing run by the ink supply system, regulating the circulation of ink from bucket to the chamber and returning it after production. Stable circulation keeps the ink at constant viscosity to ensure stable ink density on the printed substrate. Flow is maintained at a constant rate in response to the rotating anilox roll’s sucking effect. The operator raises the pressure so a wall of ink is formed at the point where the rotating cells meet the blade. This wall stops air bubbles from entering, thus preventing the foaming that can result in blistered print effects. 


Doctor blade systems are adapted according to the print width and ink / coating volume required. For paper, folding carton and flexible packaging, an ink volume of between 1.35 and 2.2 litres/m. is advised, suited for anilox diameters between 64 and 250 mmm web widths up to 6000mm. For web widths up to approx. 800mm, a closed cassette version is ideal for where different print processes can be interchanged. Such a system contains ink volumes from 0.2 litres.
 

For wider web applications especially, lightweight carbon fibre chamber doctor blade systems offer the corrosion resistance necessary to withstand alkaline and acidic cleaning fluids and inks, and light weight for easy handling. Chamber weights vary between 2.4kg and 4.1kg per linear metre (approx. 1.6 lb – 2.74 lb per linear foot).  The carbon fibre chamber’s top-coated ink-repellent surface facilitates efficient, thorough cleaning after job completion.  Furthermore, inner surfaces are curved to maximise volume and accelerate discharge.  

 

The latest chamber innovation for wide-web and corrugated printing is an ‘all-in-one’ concept, comprising a chamber doctor blade, inking system and integrated cleaning system, keeping handling and ink loss to a minimum. Available in widths from 1600mm to 6000mm, the chamber features an integrated cleaning nozzle with a robustly designed low-pressure water-shot mechanism, to ensure efficient cleaning of the chamber and anilox roll in a short time. The chamber offers fast emptying performance because the ink or coating fluid is evacuated through both the chamber’s inlet and outlet

  

Controlled ink supply featuring a chambered doctor blade combined with inking system, brings a host of benefits. It enables consistent ink density, blister-free reproduction, higher gloss values and thus improved reflection. It brings reduced running costs, through lower ink loss and efficient drying. Setup times are reduced because ink-change cycles are a matter of minutes. Automatic regulation means operators are free to focus on higher value tasks. Throughput is improved, with uncontaminated speeds of up to 600 m/min (approx. 1970ft/min) possible.

 

In conclusion, controlling ink, in an environment where the ink is closed from the atmosphere, delivers predictable quality, better productivity with reduced setup times, assurance of a solvent-free working environment, higher ink yields, longer ink life and lower maintenance costs.

The company became the first major supplier in the UK with an inline solution for digitally printed folding cartons, when it installed the four-colour Xerox iGen 4 sheet-fed digital printer with a TRESU Pinta coater integrated inline in 2015. Complementing an existing offset workflow, the integrated, single-pass digital printing – coating line is capable of up to 110 sheets / minute and printing carton up to 610µm thickness, enabling printing on-demand with low origination costs and low order quantities.

 

Alexir’s digital division has become a self-sufficient unit, employing six full-time staff. As Claire Summersby, marketing manager at the Alexir Partnership, explains, it is meeting the growing demand for short production runs: “Our Xerox – TRESU printing and coating line is filling a vital gap of between one and five thousand units, which we were unable to offer before. For brand owners, it provides a much faster route to market, allowing us to offer high-value services, like on-demand sample printing, personalised prints and multiple variations of a brand. It has attracted significant business from small market players and provided start-up companies with a springboard for growth. Furthermore, we are increasingly supporting marketing departments of larger brand-owners, by developing promotional campaigns.”

 

Dragonfly Tea, based in Newbury, UK, is benefiting from the cost-effectiveness and flexibility of Alexir Partnership’s digital carton service for its range of speciality black, green, white and caffeine-free tea sachets that are sold across the E.U.

 

“Digital is ideal for Dragonfly Tea as we can easily amend the graphics files, to accommodate the numerous flavours, regular changes to ingredients and multiple language versions,” Summersby comments. “Our ability to supply exact amounts of small quantities at short notice reduces inventory levels, reducing costs as well as the risk of stock going out of date and having to be scrapped.”

 

TRESU’s Pinta inline flexo coater provides a layer of protection and enhances aesthetic appeal. Sheets are fed to the coater automatically, from the Xerox iGen 4, immediately after the printing stage. A wide range of UV- or water-based coating media, supplied by TRESU, are available for achieving matte, gloss, full surface, spot or fine-line effects. Fast sleeve-changes and an automatic, self-cleaning coating supply system limit job changeover times to just minutes even when switching between UV and water-based varnishes. Coated sheets are subsequently transferred to the adjacent KAMA ProFold 74 gluer / folder or Kongsberg plotter.

The competitive advantage of inline flexo printing

Thanks to a stable, ergonomic and modular build, the latest mid-web presses achieve repeatable results at faster speeds, with minimal manual input. Inline flexo presses also provide the ideal platform for a lean workflow, with advanced ink supply and drying systems. And with an ability to convert recycled, thinner materials with water-based inks, they provide the solution for environmentally friendly production.  
 

While the package printing market is steadily growing, there is a noticeable trend to shorter production runs as manufacturers diversify their brands, increasing SKUs, with greater variation in pack size, and more targeted geographical availability. This practice puts pressure on converters, as suppliers reduce costs by ordering smaller volumes more frequently. The result is that it’s not unheard of for converters to print up to 15 jobs in an eight-hour shift. Furthermore, brand owners are demanding sustainable packaging solutions that minimise the burden on the environment.
 

Paperboard packaging constructions – notably folding cartons – are particularly attractive to the supply chain because they enable unique branding through a variety of design and size variations, maximum graphic coverage, easier supply-chain logistics as well as better recyclability.The key to supplying this growing market lies in controlling costs, limiting setup times, and creating a flexible printing and converting workflow where it is possible to change jobs - including formats – at short notice, and with minimal waste.
  

Inline flexo, with its capability for short setup times, speed, ergonomic operation and modularity, provides a productive, flexible and cost-controlled solution. With the appropriate configuration and support from the press manufacturer, converters using inline flexo are well-placed to succeed in this shifting market.  
 

Modularity is key

Thanks to its horizontal configuration, inline is the only flexo process to offer safe, manual accessibility at all stages in the printing / converting sequence, without the need for ladders or stairwells. A modular platform enables customisation with any number of colours as well as a wide variety of added-value converting options to deliver a finished product in a single pass. The press’s ability to print with UV- and water-based ink sets as well as metallic foil is also crucial in a multi-process line.
 

With front and back printing capabilities, it is possible to offer protective coating and pattern gluing on reverse surfaces. Following the colour positions, cold foil is often included in the configuration to achieve metallic effects. There may be additional flexo varnish units for achieving high gloss, matte, ‘velvet touch’ or aromatic effects, sometimes in creative combinations.   
 

Automated systems ensure process efficiency 

These effects require advanced ink supply systems, controls and drying systems,  in order to achieve optimum throughput, low waste and minimised setup times. Automated ink and coating circulation, with an enclosed ink supply system and sealed chamber doctor blades, ensure uniform, accurate and uncontaminated print results, fast ink changes, lower emissions and reduced waste. Crucially, these components should be seen as one system, perfectly calibrated to work together, regulating the ink or coating medium’s flow, viscosity and pressure from the bucket to the point where it is dispensed into the anilox cell.  
 

Ink supply systems – such as TRESU’s F10 iCon (pictured) -  automatically replenish the chamber at finely calibrated rates as the cells of the rotating anilox roll obtain the ink. Flow is measured by counting the pump strokes, multiplied by a stroke volume that can be estimated to an accuracy of 2.5 per cent. Stroke counting ensures that the supply system pumps precise amounts of fresh ink into the chamber at the right time.

Optimum pressure ensures ink or coating is free of air bubbles, both in the chamber and when it flows into the anilox cells. The operator raises the pressure so a wall of ink forms at the point where the rotating cells meet the doctor blade, preventing foaming caused by air entering.  The supply system also assures an accurate way of returning inks to the bucket and fast, thorough chamber cleaning, without manual intervention.
 

After job completion, the cleaning system returns almost all the remaining ink to the ink bucket, and cleans the chamber thoroughly without manual assistance, easily within five to eight minutes. Up to 20 litres of ink per colour station on each job can be saved in this way.

Ceramic and carbon fibre chambers offer optimum resistance against corrosive fluids with high pH values; for wider widths, carbon fibre chambers are easiest to handle because of their light weight.    

 

To accelerate setup times further, packaging converters commonly prefer eight to ten printing stations, even though the majority of jobs are seven colours or fewer. In most cases, therefore, the operator can prepare the next job’s idle stations while the previous job is in production, thereby cutting waiting times.   

 

Quick-change sleeve systems minimise setup times

A key factor enabling fast changeovers is a pneumatic quick-change sleeve system, allowing exchange within seconds. For optimised speed and quality, the sleeve features a recess stretching across its entire width, along which the edge of the printing plate is fixed. This recess ensures the plate’s height is equal to that of the sleeve surface when it meets the substrate. This eliminates cylinder bounce and ensures accurate register and reduced dot gain at relatively high speeds. Flexo plates come in a wide range of hardnesses, so all substrates may be coated or printed for virtually any packaging application.


Automated process control cuts time and material waste

The increased reliance on repeat orders necessitates high levels of automation, so that a host of job settings can be recalled instantly, not only saving time but reducing risk of error. The latest generation presses calibrate the press according to a host of data for each job, such as ink flow, register, impression, anilox cells, web thickness, tension, and drying temperatures, among others.

 

Servo technologies also enable fast change between the wide range of repeat sizes needed in folding carton – typically, between 480mm and 1050mm – without the need for lengthy recalibration. Heat and speed are critical for inks, coating and substrates and can mean the difference between outstanding results, good enough results, and waste.

 

Gas-heated drying systems have strong sustainability advantages. The drying system’s ability to recirculate air provides an optimal heat-exchange, reducing energy consumption and emissions further. The dryer expels hot air, to warm up incoming air. This heat exchange method generates 80 per cent of energy needs and significantly reduces emissions.  Furthermore, an important reason why inline flexo can reach higher speeds is the longer distance it offers between drying stations.  

Furthermore, inline flexo offers strong advantages when more environment-friendly production processes are demanded.  Inline flexo offers the flexibility to convert thinner, lighter and recycled packaging substrates at speed, delivering outstanding colour results with water-based inks.

 

Commitment to long-term support

A manufacturer with extensive engineering expertise coupled with experience in ancillary and drying technology, is well-placed to offer a high performance press for a profitable inline flexo workflow. Packaging printers and converters should look for supplier who regard customer support as a strategic partnership that lasts the lifetime of the press and beyond. It begins at the moment of first contact; working with the customer to design the configuration, and selecting the right components for optimum productivity, print quality, and footprint.

 

Following training, the press manufacturer, often in collaboration with co-suppliers of ink, tapes, dispensing systems and proofing equipment, works with the customer to monitor the complete workflow and seek continuous improvements in terms of quality, cost reduction and productivity.

As a minimum, the press manufacturer should have the resources to offer global care programmes that include round-the-clock support, on-going machine optimisation, training and materials testing – remotely and on-site.

 

Inspired by the ‘4M’ manufacturing programme management philosophy, the press manufacturer seeks to optimise human resources, machines and equipment, materials and production methods employed, to drive waste out of the workflow and help everyone adopt a ‘lean’ manufacturing culture. The benefits are not only financial, but reputational, principally as lowering waste is the making of a sustainable operation.

 

Arguably, today’s package printing ‘Formula One’ races are won in the pit-stops, and to a great extent, competitiveness in print depends on similar co-ordination and agility during setup times.  Flexo has numerous variables and each job change can require a complex sequence of actions, so there are benefits to be reaped even by reducing waste – whether measured in seconds, linear web metres or kilos of inks – at each stage of the changeover.

 

Working towards that aim, the press manufacturer’s technical engineers are likely to be monitoring and researching areas such as speed, waste levels, and working procedures. For example: is the logistics between the printing machine, warehouse and workbench arranged to eliminate waiting times? Is there duplication or excessive stockholding? How can we maximise ink yields? Will the supplier give you the best production productivity and life out of their consumables and ancillary equipment?  Does their sustainability ethos match yours and that of your customers? These are just some of the many questions packaging printers and converters should ask supplier to be able to take performance, productivity and profitability to the next level.

 

In a dynamic, service-driven market where uptime is critical, the willingness of the OEM partner to act as a partner for achieving continuous improvement is paramount for maintaining competitive edge and a sustainable process.

At the FEFCO Exhibition and Technical Seminar, TRESU Group will showcase its ancillary solutions for automated ink logistics in wide-web flexo printing, bringing consistent colour quality at faster production speeds and reductions in material waste, setup times and labour costs (stand 104 / 105, Messe Wien, Austria, 11 to 13 October 2017). 

 

Together, TRESU’s programme of ink supply systems and chamber doctor blades, with corrosion-resistant carbon fibre and ceramic surfaces, provide a fully enclosed solution for regulating ink flow from bucket to printing substrate.   

 

The F10iCon ink supply system for automated flow regulation

TRESU’s F10iCon ink supply system regulates ink flow, pressure and viscosity from the bucket, through the chamber and to the press, maintaining constant, pre-set ink density values for complete production runs. When ink changes are required, the F10 iCon system carries out fast and thorough chamber cleaning automatically, and returns almost all unused contents to the bucket for reuse on subsequent jobs. With the F10 iCon, simultaneous ink changes on printing stations takes minutes, delivering significant time and materials savings per job.

 

Chamber doctor blade systems: uniform print quality print and easy use

The TRESU chamber programme includes lightweight, corrosion-resistant carbon fibre and ceramic variants and covers all flexo printing situations, in widths from 185mm (7.3in) up to 6000mm (236in). Assisted by the company’s patented seals and constant pressure maintained by the supply system, TRESU chamber doctor blades prevent leakage and air contamination, thereby ensuring clean, blister-free print results with fast drying characteristics, better reflection and higher gloss values. When doctor blades need replacing, TRESU’s patented clamping systems enable changeovers in less than two minutes.

 

The enclosed chamber, created by the seal and precise blade positioning, ensures pressure and flow rate are maintained at desired levels without manual intervention. This stops air contaminating the chamber and results in foam-free transfer of ink / coating directly to the anilox cells. This in turn ensures a clean, blister-free printed image with fast drying characteristics, better reflection and higher gloss values, whether on paper or film. The enclosed chamber also prevents solvents from escaping and protects the ink from degradation due to exposure to the atmosphere. Depending on surface and material type used, printing speeds can exceed 600m/min.

 

MaxiPrint Concept: optimised efficiency with integrated ink supply and cleaning

The TRESU MaxiPrint Concept combines a compact ink supply system with an integrated cleaning system, providing the benchmark for low ink loss and setup times in wide web and corrugated flexo printing. The chambers are available in widths between 1600mm (63in) and 6000mm (236in), with ceramic or carbon fibre surfaces offering protection against corrosion by substances up to pH12.

 

The MaxiPrint Concept chamber’s cleaning nozzles with robustly designed water-shot mechanisms provide an ink change and cleaning cycle within 3-5 minutes. It comes with a peristaltic or diaphragm ink supply system and can be adapted to any press. With a global support network of subsidiary companies and agents, TRESU provides the resources and expertise to provide long-term application support, training, and management of retrofitting projects to raise the performance of existing presses with tailored ink logistics solutions.

 

Chris Wolters, areas sales manager, TRESU Group, will present a paper on the value of automated ink logistics at the FEFCO Technical Seminar on 12th October, from 4:25pm. Mr. Wolters comments: “TRESU ancillary solutions are forming the basis of a lean manufacturing workflow at pre- and post-print corrugated facilities worldwide, driving waste from processes and enabling compliance with demanding colour targets. At FEFCO 2017, our technical team will be on hand to show the value that TRESU’s tailored automated ink logistics can bring to your business.”

 

Besides ancillary solutions, TRESU also offers complete coating systems for integration with sheet-fed digital folding carton printing systems, and high-performance hybrid flexographic printing and converting lines for paperboard packaging and gamecard applications.
