Visit TRESU Group at booth 657 at the McCormick Place, Chicago, IL, USA, September 10-14. TRESU’s ancillary program comprises ink supply systems, together with chamber doctor blade systems for narrow, mid and wide-web flexo applications, providing a complete solution for regulating ink flow throughout the press – from bucket to substrate. This significantly reduces material and ink waste, setup times, emissions and labor and results in consistently accurate color targets at speeds that can exceed 600m/min (approx. 2000ft/min.). Additionally, TRESU’s broad product line of ancillary solutions includes process temperature control systems and dampening water circulators for sheet-fed and web offset presses, infrared and hot air drying systems, and coating/ink circulation systems for water-base, UV, and solvent applications.

 

The F10 iCon ink supply system for automated flow regulation

TRESU’s F10 iCon ink supply system regulates ink flow, pressure and viscosity from the bucket, through the chamber, 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 cleaning of the chamber automatically, and returns almost all unused contents to the bucket for reuse on subsequent jobs. With the F10 iCon, simultaneous ink change cycles on printing stations takes minutes, delivering significant time and materials savings per job.
 

Chamber doctor blade systems deliver uniform print quality print and ease of use

The TRESU chamber program includes lightweight, corrosion-resistant carbon fiber and ceramic variants and covers all flexo printing situations, in widths from 185mm (7.3in) to beyond 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.
 

For wide web and corrugated flexo applications between 1600mm (63in) and 6000mm (236in), the carbon fiber TRESU MaxiPrint Concept -reduces cleaning time and improves color quality and consistency. Comprising a closed chamber, an integrated ink supply unit and a cleaning cycle, MaxiPrint Concept offers fast, automatic internal cleaning, corrosion-resistance, improved print quality consistency and reduced ink loss. The chamber’s cleaning nozzles with robustly designed water-shot mechanisms provide an ink change and cleaning cycle within 3-5 minutes.
 

Versatility and productivity: the Flexo Innovator hybrid in-line printing press

There will also be information about TRESU’s hybrid Flexo Innovator printing line with integrated finishing options. With several installations worldwide, press has proved to be a highly efficient, productive solution for paper, carton board, laminates, metallic substrates and unsupported films with both water-based ink and UV OPV coating media. The press can be equipped with automatic inking and control systems to minimize operator intervention, setup times and material waste. Enclosed, automatically controlled ink circulation and uniform ink laydown is achieved by regulating the ink chemistry during the printing process.

 

Productivity-enhancing features may include inline inspection and color management systems; hot air drying; unwind / rewind stands as well as finishing options like cold foil, laminating, die-cutting, embossing, and rotary cutting and sheeting, to give the Flexo Innovator unparalleled flexibility.

 

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 30000, HP Indigo 12000 and HP Indigo 10000 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.
 

The coating systems may be complemented by the recently introduced TRESU Flexo Kit, a flexo printing unit with integrated peristaltic pump, for applying high-gloss metallic, Iriodin®, and other special-effect coating finishes. 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.

 

TRESU’s iVarnish UV and water-based coating media are specially formulated for the iCoat 30000. There will also be new varnishes with improved adhesion properties so that plastic as well as board substrates may be run. One potential application for these media is the retail loyalty card. The newest addition to the sleeve range is a ready-to-print sleeve for flood varnish application, assuring optimized print results at top speeds. The TRESU iCut cutter provides a fast, straightforward means of imaging flexo plates or sleeves for spot coating effects. Accommodating sleeve-mounted B2-size plates used by TRESU iCoat units, the TRESU iCut processes the same software as that used by the digital printer and the accompanying analogue coater. The plate, mounted on a sleeve, is cut directly from the file, without the need for shrinkage compensation, within ten minutes. 

 

Also available is an inkjet coating feature called the TRESU iJet, for variable positioning of spot coatings. Integrated into the iCoat, it features up to 11 print heads that can be positioned in the cross direction of the sheet to apply coating anywhere on the surface of the image. 

 

Chilling systems for efficient heat extraction

TRESU will also highlight its chilling systems for sustainable, efficient heat extraction from digital, flexo and offset printing presses. TRESU’s new 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, alerting the TRESU service department about any performance issues, facilitating remote diagnostics and enabling swift remedial action.

 

Highlights of the range include the compact SCi single-zone chiller with remote condenser configuration for ink rollers on sheet- and web-fed offset presses; the CCi combi-chiller for continuous circulation of water to the ink rollers; the UCi UV chiller for providing temperature-controlled process water to the UV-curing system; the MCi multi-zone controller to control water temperature where independent temperature control is needed for every printing unit; and the ZCi zone control module for  managing multiple temperature control needs on sheet- and web-fed offset presses.

 

TRESU also offers the DPC (Digital Process Chiller) 5-6 iSeries for HP Indigo Series 4 presses, exhausting heat to remote external condensers. Each chiller and condensing unit has a heat extraction capacity of 42.2kW (144,000 Btu/hour or 1.2 refrigeration tons). The process does not involve the plant’s HVAC (heating, ventilation and air conditioning) system.

The competitive advantage of inline flexo printing

Short text:

Allan Sander, Vice-President Solutions, TRESU Group

Inline flexo is a competitive, single-pass solution for sophisticated, high-quality packaging - whether short and long production runs are needed.

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.

SCA Gemerská Hôrka, one of Slovakia’s largest manufacturers of female hygiene products, is reporting a ‘step change’ in quality, safety and process efficiency improvements, after installing four-colour TRESU flexo printing units featuring F10 iCon automated ink supply systems on several of its converting lines. 


Replacing offline single printing units with an ‘open’ ink supply and chamber, the new TRESU printing units integrate into the production lines, enabling SCA to manufacture its products and apply brand identification graphics, in a single pass for the first time. 

Featuring two printing chambers, the printing units handle non-woven liner products between 85mm and 300mm wide, using water-based inks. The TRESU printing units with F10 iCon supply system were chosen for their robust design and high levels of automation that ensure better output, predictable quality and reduced waste.

TRESU’s F10 iCon ink supply system regulates ink flow, pressure and viscosity from the container, through the chamber, to the press in a fully enclosed environment, maintaining constant, pre-set ink density values for complete production runs. Furthermore, the F10 iCon performs fast and thorough chamber-cleaning automatically, returning almost all unused contents for reuse. Simultaneous ink change cycles on printing stations take minutes, delivering significant time and materials savings per job. The units at the Gemerská Hôrka factory also feature TRESU’s chamber doctor blades with rubber seals and clamping systems for blade exchanges within two minutes. 

Peter Kelemen, technology area engineer from SCA Gemerská Hôrka comments: “The existing ink supply system in previous systems was based on an open ink chamber and manual viscosity measurement. This created a challenge when we needed to change inks and chambers, as the cleaning process was slow and there was risk of contamination.

 

We therefore sought an ergonomic solution that provided effective branding in multiple colours as well as reduced waste. The installation of TRESU’s printing integration unit featuring the F10 iCon provides a step change in performance, bringing predictable quality without manual input, with reduced logistics, faster changeover times and a clean, safe, emission-free working environment.”  ¨

 

TRESU’s mechanical and electrical engineering team managed the installations together with training sessions for SCA operators over a six-month period. Kelemen concluded: “SCA has benefited from the structured and highly professional project management from TRESU that has enabled a swift and smooth installation. This has been a very successful project for both companies and an excellent base for further future collaboration.”

Using printing sleeves and featuring a dedicated anilox roll, chambered doctor blade and pump, the Flexo Kit unit provides a separate uncontaminated supply system for gold, silver, aerodyne, and other special-effect coating finishes.

The unit is fine-tuned to the unique flow and drying characteristics of metallic inks, so ink can be applied at speeds of up to 4600 sheets per hour, equivalent to maximum printer and coater speeds.  The pumps and chamber doctor blade provide an enclosed ink flow throughout the unit, allowing tight regulation of viscosity and pressure, and preventing foaming. Its automatic cleaning facility means ink changes can take place in minutes. Additionally, the unit’s anilox rolls feature elongated cells to handle relatively large particles without clogging.

Flexo Kit is built for fast integration into existing iCoat units, and can be specified for inclusion on new machine orders.

Kim Krintel, vice-president, TRESU DigitalSolutions, comments: “Metallic inks are an essential requirement for folding carton niches such as chocolates and confectionery, and flexo is the ideal process for achieving the high-gloss effect. TRESU Flexo Kit enables digital converters to add this high-value embellishment with minimal extra logistics, inline and at fast speeds.”

The digital line, the first of its type in Scandinavia, serves its customers in the industrial, food, confectionery and personal care sectors across northern Europe. It complements an existing offset workflow that includes a six-colour Heidelberg Speedmaster XL75, die-cutters and other finishing equipment.

The installation enables Kartongbolaget to introduce a new flexible digital folding carton service, “Fast Track”, offering short and personalised runs of up to 5000 sheets as well as sample production, delivered within five days. Its cost-effectiveness is enabling niche and luxury brands to achieve retail listings with added-value packaging presentation for the first time.

Furthermore, the company is offering a number of additional services made uniquely possible by digital printing: versioning, variable data printing for limited editions and tracing in the supply chain, personalised products, interactive packaging linked to social media competitions and samples on-demand.  

Joakim Johansson, managing director, Kartongbolaget, comments: “We were determined to invest in HP Indigo’s liquid toner technology because of its proven performance and versatility. It would give us the option to print board up to B2 size, and also assure us of low ink migration to meet new food legislation. When we saw at first hand the quality and performance of the HP Indigo 30000, along with the TRESU iCoat coater at the HP Graphics Experience Center in Barcelona, we knew there was no alternative.”

With its priming feature and ability to achieve 97 per cent of the PANTONE® Colour gamut, the HP Indigo and the TRESU iCoat 30000 coater deliver indistinguishable results to offset, on numerous substrates.

TRESU iCoat 30000 is configured inline with the HP Indigo press, enabling seamless single-pass printing and coating. The integrated digital printing and flexo coating line 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 press can also print on plastic substrates, accommodating PVC and polypropylene up to 630µm, and PET up to 400µm.

Where no substrate or varnish change is needed, setup times for each job are about one minute.

Seamless quality

TRESU iCoat 30000 is a flexo coating unit that applies water-based or UV-varnishes in a single pass directly after the digital printing stage, protecting the underlying graphics and providing value-added aesthetic appeal. The iCoat unit’s automatic chamber cleaning and fast sleeve change facilities enable varnish change-overs within ten minutes.

After coating, the automatically stacked sheets are wheeled to one of four separate die-cutters that also take offset jobs, before gluing. 

The company’s own design studio develops packaging and promotional concepts, creating complete, affordable branding solutions for small businesses seeking a strong identity that can be consistently applied in all situations.

Joakim Johansson said: “The flexibility of our HP Indigo – TRESU digital line gives our customers a huge advantage in targeting consumers with more relevant products. So one production run can be split into multiple runs with different language versions, regional variations, brand varieties and limited editions, without any extra setup times, manual input or start-up waste.”

“Above all, this digital investment gives the potential to widen our offering beyond the packaging, and provide integrated logistics solutions that remove waste from the supply chain,” Johansson concludes.

Available for printing widths in excess of six metres, TRESU’s ancillary solutions offer the advantages of faster, automated, enclosed ink flow and circulation, with minimum waste.  
 

Automated ink regulation and cleaning with the F10 iCon ink supply system

The F10 iCon ink supply system regulates ink flow, pressure and viscosity from the bucket to the flexo press, thereby maintaining constant, predetermined ink density values throughout production runs. Additionally, when ink changes are required, the supply system provides fast, thorough automatic cleaning of the chamber, and returns almost all unused contents to the bucket for reuse in subsequent jobs. The F10 iCon provides simultaneous ink change cycles on printing stations in minutes, resulting in significant time and materials savings per job. 
 

Chamber doctor blade programme: uniform quality print and easy handling 

TRESU’s chamber doctor blade systems, especially when used in conjunction with the F10 iCon ink supply system, offer further efficiency and quality benefits. The TRESU chamber programme includes lightweight, corrosion-resistant carbon fibre and ceramic variants and covers all flexo printing situations, including printing widths exceeding 6000mm (236in) often seen in corrugated printing.  Featuring the company’s patented seal system, TRESU chamber doctor blades prevent leakage and air contamination, thereby ensuring clean, blister-free print result 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. 

For wider widths particularly, the carbon fibre chamber doctor blade range offers easier handling including portability thanks to their light weight. Furthermore, their top-coated ink-repellent surface protects against detergents and adhesives with pH values of 9.0 and above, and makes cleaning easier. Curved inner surfaces maximize volume and facilitate controlled discharge.  
 

MaxiPrint Chamber Concept for fastest cleaning cycles

Alternatively for web applications between 1600mm and 6000mm, the MaxiPrint Concept is a light-weight carbon-fibre or ceramic chamber, with integrated inking and cleaning systems, for fastest cleaning cycles. The chamber and anilox roll are automatically cleaned thanks to an integrated cleaning nozzle with a robust water-shot mechanism that maintains a low pressure to limit water loss. Relatively fast emptying occurs because ink or coating fluid is evacuated through both the chamber’s inlet and outlet. The ink change and cleaning cycle is typically completed within approximately five minutes.  

Based in the Chaoyang District of Beijing, TRESU’s China subsidiary offers fast-response technical support, and smooth management of ink supply retrofitting projects that can significantly enhance the performance of existing printing lines. 

Gray Chang, sales and technical manager, TRESU China comments: “For China’s packaging suppliers, achieving greater process efficiency is of paramount importance, in order to control rising production costs, especially with respect to labour, in an uncertain economic climate. Flexo offers a competitive alternative, especially in corrugated preprint production, with its the high standards of quality and relatively low consumable costs. TRESU’s controlled ink supply solutions with light-weight, durable carbon fibre chambers are ideal for meeting the market’s challenges - automating and eliminating waste from the process, while providing the basis for higher print speeds without compromising quality.”

TRESU Group has developed a multi-colour flexo printing unit for applying patterns to non-woven disposable sanitary napkins. Customised to the specifications of the production line, the printing unit comprises up to four water-based colours, a hot air dryer and, at the embossing point, a register guidance camera. It is capable of printing on non-woven materials between 15 and 22gsm, especially pre-perforated PE polymers. The unit also offers a compact footprint and an operator-friendly design.
 

Located at point of embossing, the register guidance system ensures synchronisation of the printed pattern with the crease in the centre of the napkin, at speeds of up to 400 metres per minute (approximately 2000 pieces per minute). Using the converting machine interface signals as point of reference, the control module influences the servo motors to ensure accuracy is maintained on-the-fly throughout the production run.   Servo drives ensure automatically controlled, precise print speed and ink flow, so that operation without in-house flexo experience or handling is possible.

Allan Sander, vice-president, TRESU Solutions, comments: "Consumers are increasingly seeking assurance about the quality of their products, and research has shown that there is stronger loyalty to napkin brands with recognisable printed designs such as icons or logos  printed on the fabric. TRESU’s customised printing integration   system enables the personal hygiene industry to achieve this, while maintaining a cost-controlled, flexible, single-pass operation.”     

The integration unit includes TRESU's F10 iCon ink supply system with automatic cleaning, to constantly feed the printing units and maintain optimum viscosity, temperature and pressure. 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.  

The system is optimised for fast job changes. 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 ability to seamlessly integrate the printing operation into the existing converting and assembly line means that customers can avoid the costs and lengthy lead times associated with outsourcing. 

“TRESU collaborated closely with the customer's research and development division at every step from the concept stage, to customise the machine to suit production requirements and skills levels,” stated Mr. Sander.

 'The projects have been a large success for the customers, with integrations of our high level printing technology into a large number of hygiene converting lines at locations in Europe, USA and Mexico. From TRESU's perspective, we are proud to have developed the requested solution on time despite demands on safety, process technology and a tight time frame.”

The system has enabled several of the world’s leading packaging converters and brand owners to achieve significant improvements in efficiency, print quality and environmental performance since its introduction in 2012. Tetra Pak, the world’s leading food processing and packaging solutions company, has chosen to install the F10 iCon ink supply system on both its new and existing flexo printing operations around the World.

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. 

Christian Fogh, TRESU’s innovation and R&D manager, comments: “The F10 iCon ink supply system has proved to be an essential tool for both meeting stringent print quality demands, improving machine productivity and driving out waste in the flexo workflow. In an age of shorter production runs, therefore, the supply system is an ideal solution for achieving a lean workflow that also meets sustainability goals, by reducing environmental impact and facilitating cleaner, safer working conditions.”.

Polymark is well-known in the region for sales of inks and consumables and as a distributor for Manroland. Polymark will sell and provide technical support for TRESU ancillary equipment, which includes ink supply systems and chamber doctor blades. Together, these provide the complete logistics for controlled, automatic ink circulation on flexo presses, enabling printers to improve print quality, optimise ink use and increase productivity. 

“The addition of Polymark as agents for TRESU Ancillary is another important step in the development of our sales and support network,” said Steen Rasmussen, area sales manager, TRESU Ancillary. “It is a timely appointment as this is a region where the economy is growing and flexo printers are increasingly focused on improving quality and efficiency while reducing waste.” 

TRESU and Polymark believe many printers in Baltic region can benefit from retrofitting older flexo presses and finishing lines with TRESU systems that can extend their lives, improve competitiveness and meet today’s market demands. Steen Rasmussen comments: “The global trend towards shorter production runs and stricter colour consistency targets expected by packaging buyers has made it essential for converters to automate and control processes as much as possible.” 

“In flexo printing, controlled ink logistics is essential for remaining competitive in these situations. Automated cleaning cuts makeready times by hours, for example by performing jobs simultaneously on each print station, as opposed to consecutively. Enclosed supply systems are also the basis for controlling flow rate, pressure and viscosity, assuring unblemished printwork and exact ink densities at faster speeds – in some cases, exceeding 600m/min – without evaporation or splashing.”   

TRESU provides equipment for all flexo printing applications, from narrow-web to corrugated presses. Highlights include the F10 iCon ink supply system, and chamber doctor blades up to six metres wide.   

“This is a great opportunity to introduce our customers to more of what TRESU has to offer,” said Nadezhda Matveeva, general manager, Polymark SIA. “We see more attention oriented towards investment in the ancillaries with converters trying to boost the productivity this way, rather than investing in new machinery. TRESU can offer both, but with the right ancillaries, our customers can save money and at the same time gain in efficiency.” 

Polymark will also support the retrofit of coating units for offset presses which can open new markets for semi-commercial, commercial and publications printers by adding value to products. “Polymark’s knowledge of the markets and technologies as well as its well-known team will make it a major contributor to our growing sales and support organisation,” Mr. Rasmussen concluded.

A compact system with two speed-controlled peristaltic pumps, TRESU XL5i is easy to operate thanks to semi-automatic cleaning and timer settings.

Used in combination with a chamber doctor blade and customized open-cell anilox roll, TRESU XL5i provides fully enclosed circulation from the bucket to the point where the ink or varnish fills the anilox cells, thereby enabling pressure and control needed to delicately handle the medium. The enclosed system prevents contamination of air inside the chamber that can lead to foaming and undesired blistering of the printwork. 

Printing applications for which the XL5i are suitable include opaque white, gold and silver metalure, pearl lustre, blister coating, scented, high-gloss, scented or silky soft touch effects, on folding carton, self-adhesive labels or metallised papers. 

Henrik Kristensen, vice-president, TRESU Ancillary, comments: “Varnishes responsible for high lustre, brilliant colours and appealing tactile effects are powerful ways of adding brand value - especially for luxury and personal care packaging, where a striking point of sale impact is crucial to achieve sales. However, the functionality of these varnish types depends on relatively large particles that are delicate. TRESU’s XL5i circulator ensures these coating media are carefully handled with care, at precise viscosity and pressure levels, so the desired print result can be achieved without disturbance at high production speeds.”

An exclusively digital printing business, Digilinck has expanded rapidly since it was established in 2011. Now with a workforce of 25, the company supplies luxury packaging and self-adhesive labels to retail goods and pharmaceutical markets in Northern Europe. Digilinck attributes its fast growth to the quality and user-friendliness of its two existing HP Indigo WS6600 roll-to-roll presses, which enabled the company to supply short-run orders, responsively, and provide a host of added value services like variable data and personalized products. Their success in meeting their client base’s needs with fast turnarounds attracted significant new business, and in 2014, the company supplied in excess of 12000 orders.
 

Digilinck’s owner and founder, Vincent Oosterlinck, explains: “The crucial factor in our success at Digilinck has been our ability to offer fast lead times, and exploit the full potential of the digital process. However, the growth we experienced made it challenging to meet commitments, even when both machines were running three shifts a day. We needed to invest in a new press urgently.” 
 

The company installed a seven-colour HP Indigo 30000 Digital Printer, integrated with a TRESU iCoat 30000 coater. Together the two machines provide a seamless single-pass printing and coating line for folding cartons, with minimal logistics or material waste. TRESU iCoat 30000 is a double coating unit that can apply water-based or UV-varnishes directly after the digital printing stage, both to provide protection to the underlying graphics and to enhance aesthetic appeal.  
 

Digilinck’s printing and coating line from HP Indigo and TRESU runs at 3450 B2-size sheets per hour, with a maximum of 4600 sheets per hour. This enables the company to print jobs in excess of 30,000 units in approximately two hours. However, both machines are capable of up to 5000 sheets / hour on board substrates of maximum format 750mm x 550mm. The coater’s quick-change sleeve technology and fast chamber cleaning cycles make it possible to exchange jobs and varnish sets in minutes.
 

Vincent Oosterlinck comments: “The HP Indigo 30000 together with the TRESU iCoat Twin 30000, was the ideal complement to our WS6600 Digital Press machines.  It delivers the identical quality cost-efficiently, yet with twice the productivity.  This gives us the ability to grow and maintain the flexibility on which our competitive edge depends.”

Inline coating for digital folding carton lines: simplified, efficient workflow

Short text:
TRESU Group manufactures three solutions for coating digitally printed applications. While primarily designed for the folding carton market, digital printing has blurred the traditional application boundaries.

Inline coating for digital folding carton lines: simplified, efficient workflow

TRESU Group is an advocate of inline coating and finishing for digitally printed applications. As digital press speeds have increased, there are powerful workflow, quality and economic reasons for coating to be inline, unlike in the day when finishing equipment ran at twice the speed of digital presses. Submitting uncoated digital print to unnecessary additional handling, such as is required by near-line or off-line coating, is to negate some of the benefits of coating.

 

The TRESU iCoat 30000 and TRESU iCoat 30000 TWIN are designed for inline configuration with the HP Indigo 30000 Digital Press. The TRESU Pinta coater is designed for inline use with the Xerox iGen 4, the Xerox iGen5 and the Xerox iGen 150.These solutions operate at the same speed and handle the same format sizes and range of substrate weights.

 

At drupa 2016, TRESU introduced its iJet inkjet coater for inline variable UV-spot varnishes. The TRESU iJet coater may be used with the HP Indigo 10000, 12000 and 30000 Digital Presses. When used with the last of these, it may be used in conjunction with the TRESU iCoat 30000. This represents a major step development in varnish application and opens a wide range of new enhancements using variable data for folding carton and other applications.

Kim Krintel, vice president, TRESU DigitalSolutions, TRESU Group, 14-16 Eegsvej, 6091 Bjert, Denmark. Email: c/o Helene Gleerup, hgl@tresu.com

 

2. What digitally printed applications are most likely to be coated and why?

TRESU’s coating systems (TRESU Pinta, and TRESU iCoat 30000) are designed for use with digital folding carton presses. The new TRESU iJet, however, may also be used with HP Indigo 10000 and 12000 Digital Presses that are used for commercial applications, photobooks, books, posters, and applications on films and metalized substrates.

 

There are three reasons for coating folding cartons: protection of the printed surface; product enhancement, and food protection. Each of these adds value to the product and can ultimately help its saleability.Digital printing and coating also facilitates and reduces the cost of sample and trial run production, and enables more versions to be tested more quickly and more cost-effectively.

 

3. What should a print provider consider when looking to invest in a coater for their digital presses?

Given that TRESU’s coaters are designed for use with specific digital presses, many decisions have already been made for the print provider by the press manufacturers. However, among the qualities a converter should look for are: ease of use, reliability, robustness of build, versatility, and support provided. Also, the converter should consider the value added to products, the cost-effectiveness of enhancements for the brand owners and the return on Investment.
 

For HP Indigo press owners, the option of having the TWIN coater (double coater) should also be investigated. The TRESU iCoat 30000 TWIN enables spot varnishing and flood coating (gloss or matte) in a single pass. Alternatively, the iCoat 30000 (standard) can be used in conjunction with the iJet coater. For high-end and luxury applications, all three systems may be deployed, with the iJet adding a second spot gloss element with a tinted varnish.
 

4. What specific considerations should print providers take into consideration when coating inkjet output?

Neither HP nor Xerox digital presses are inkjet.

 

5. What specific considerations should print providers take into consideration when coating toner-based output?

Particles from the Xerox iGen presses have been fully fused by the time print gets to the TRESU Pinta coater. The flexographic application of water-based or UV-curable varnishes does not impact the print surface, so no special considerations are necessary. The straight path from press to coater puts no strain on the substrate and the conveyor system uses no pins or grips that could compromise the integrity of the print or sheet. Varnishes are dry by the time the sheets are moved to the stacker.

 

6. What challenges, if any, do print providers that operate hybrid environments face in terms of coating?

When digital presses operated at half the speed of finishing/coating equipment, it made sense to use near-line/off-line configurations for these processes. The risk then was that printed sheets could be damaged (either the sheet itself, or the printed surface) in transfers from the press to holding area, and then from holding area to finishing line. This risk is eliminated by the reduced, and fully automated, handling with inline finishing.

TRESU also supplies coating systems for conventional (offset and flexographic) presses.
 

7. Are there any media characteristics that are particularly challenging to coat? Why or why not?

Digitally printed folding cartons from the Xerox iGen 4, Xerox iGen 5, Xerox iGen 150, and the HP Indigo 30000 Digital Press (also the HP Indigo 10000 and 12000 Digital Presses) will be printed either on special digital board, or the stock will be primed prior to printing.

TRESU’s digital coaters will therefore successfully coat all successfully digitally printed folding cartons.

 

8. Can you please give a description of product lines targeting high-volume digital production environments? Were any of these launched at the recent drupa event? What applications do they target?

Just as digital printing has blurred the traditional boundaries of commercial printing, label and carton converting, and book and newspaper printing, so too has the notion of “high volumes.”

 

With easily printed variable data, it is possible to have runs of tens of thousands of a single SKU but with each single item being different. The difference may be a simple unique product identifier (number, barcode, or QR code); different details relevant to where the product will be sold (e.g., regional contact details); or, complete personalization.

 

The TRESU Pinta, iCoat 30000 and iJet coaters operate at speeds up to 4,600 (29.92 x 20.87in.; 750 x 530mm; B2) sheets per hour. Depending on the size of the carton, daily runs can be upwards of a million units per day. However, the rise of digital folding carton production is about applying technology to address a number of goals – goals of both brands and converters. These include, shifting from price-driven commoditized print to value-driven packaging that enhances product appeal (or product protection/integrity) cost-effectively. Digital folding carton production also meets the brand owners’ goal of cutting time to market, streamlining logistics, reducing packaging stock-holdings (and resultant waste (about 60 percent) and cutting warehousing costs.

 

Digital printing delivers all of these things, and while unit costs may be higher, the end-to-end costs are greatly reduced. As a result, enhancements through matte coatings and spot gloss varnishes are cost effective ways of making consumer goods, cosmetics, food and beverages, and personal and health care goods more competitive on the shelf, while offering protection to food, pharmaceuticals and industrial goods.

TRESU’s chamber doctor blades, especially when combined with the company’s F10 iCon ink supply system, provide an enclosed, automatic means of controlling flow rate, pressure, viscosity, from bucket to anilox roll. Resulting benefits include reduced ink and substrate waste, uniform print quality, increased press speeds, shorter cleaning times and reduced emissions.
 

Chamber doctor blade program for enclosed, sustainable, efficient ink supply

The TRESU chamber doctor blade program includes lightweight, corrosion-resistant carbon fibre and ceramic variants for all converting and coating applications. They range from closed-cassette chambers for label presses, to chambers in excess of 6000mm wide (236in) for corrugated board printing.
 

The chambers feature the company’s patented seal system. This prevents leakage and air contamination, thereby ensuring clean, blister-free print result 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.
 

Exhibited chambered doctor blade systems include the FlexiPrint IMW E-Line, for widths of up to 1800mm (70.8in) and speeds up to 500m/min (1640ft/min); and the closed-cassette FlexiPrint Reservoir, which needs no pump and operates at press speeds of up to 300m/min (984ft/min).

For widths beyond 1600mm (63in), TRESU’s lightweight carbon fibre chamber doctor blades include a top-coated ink-repellent surface, protecting against detergents and adhesives with pH values of 9.0 and above, and offering easy cleaning. Curved inner surfaces maximize volume and facilitate controlled discharge.  
 

F10 iCon ink supply system automates flow and ink change cycles

TRESU’s F10 iCon intelligent ink flow system provides pressure-controlled ink to the press at a consistent flow rate, according to predetermined parameters, with minimal supervision needed. This energy-efficient system also returns approximately 90 per cent of ink remaining in the press to the bucket after the production run. It also provides fast, thorough automatic cleaning of the chamber and hoses, completing a complete ink change cycle on all printing stations simultaneously within minutes.  This results in significant consumption and changeover savings.

Modular Flexo Innovator printing line for seamless, multi-process package converting 
 

Also available at the TRESU booth will be information on the Flexo Innovator hybrid printing line for paper and carton board applications. 

This modular printing and converting line for corrugated and folding carton manufacturing offers short setup times, reduced handling, speeds exceeding 600m/min (approx. 2000fpm) and high output.  Customised to end-user performance requirements and built with TRESU’s 30 years of press building and engineering expertise, the Flexo Innovator offers a flexo platform in 670mm, 900mm, 1100mm, 1400mm and 1700mm widths.
 

Productivity-enhancing features include inline inspection and colour management systems that maintain quality consistency on-the-fly throughout the printing run; a hot air drying system that reduces emissions by using re-circulated air; and high-efficiency unwind / rewind stands limit butt-splicing waste to one diameter of paper stock on the core.  Customers may choose to include a host of complementary processes inline including reverse-printing, cold foil, laminating, die-cutting, embossing and sheeting.
 

The Flexo Innovator’s inline configuration can print and finish paper, carton board, laminates and metallic substrates.
 

Chilling and Temperature Control

TRESU’s new intelligent iSeries chillers offer an efficient control platform for cooling analog and digital presses as well as ink supply systems. SCi Single Zone Chiller is a compact single zone chiller for sheetfed or web offset press; the CCi Combi chiller provides continuous circulation process water to ink rollers. Both use a remote condenser to absorb heat from the press and reject it externally. The UCi UV chiller provides temperature-controlled process water to UV-curing systems; the MCi multi-zone controller is suited for waterless printing. Multi-zone controllers are used where there is a requirement for independent temperature control for each printing unit.  
 

TRESU chillers interface directly with TRESU’s Internal Diagnostic Monitoring System (IDMS) that instantly alerts TRESU’s service department of any warnings or control setting disturbances. Each chiller features a unique, passcode-protected IP address to allow online remote diagnostics by TRESU’s technical support team.

The lightweight carbon fibre chambers, now available in wider widths from 1600mm to 6000mm, offer improved chemical resistance, optimised flow and safe, easy handling.The carbon fibre composition gives high-strength qualities, enabling a relatively low weight of between 2.4kg and 4.1kg per linear metre (approx. 1.6 lb – 2.74 lb per linear foot), thus easing chamber exchange.

The chamber’s  top-coated ink-repellent internal surface provides extra protection against ink and detergents with high and low pH-values and ensures efficient cleaning after job completion. Additionally, a clamping system allows stainless steel blade changeovers within two minutes.

 

Because of its simplicity and high level of automation, the TRESU carbon fibre chamber can be cleaned and prepared without being removed from the press. When used with an ink supply and cleaning system, such as TRESU’s F10 iCon, the chamber doctor blade offers a fully automated and enclosed means of circulation, maintaining precise flow, pressure and viscosity, as well as eliminating leakage and evaporation during the print run, and significantly reducing setup times. 
 

The enclosed environment also stops air contaminating the chamber and results in foam-free transfer of ink / coating directly to the anilox cells, also at fast speeds. 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.

 

TRESU’s complete range of ancillary products, exhibited at the drupa 2016 stand, includes solutions for the narrow-web market. The company is also showing units from its Flexo Innovator hybrid printing line, for the folding carton market, recently purchased by U.S. packaging converters WestRock and Dominion Packaging. 
 

Henrik Kristensen, vice president, TRESU Ancillary, comments: “Thanks to its time-saving advantages, optimised fluid control and resilience, the TRESU carbon fibre chamber offers a long-term solution for high productivity, low ownership costs and uniform quality. The extension of the range to 6 metres will be of particular benefit to converters in the post-print corrugated market.”

The joint presentation, by TRESU Group COO Søren Maarssø and GSE Dispensing marketing director Maarten Hummelen, provides a vision of efficiency at all stages of the ink workflow, from its arrival from the supplier, through the recipe preparation and proofing stages and its journey through the press to the point where it is applied on to the printing plate.

 

Maarten Hummelen looks at on-demand colour preparation, stock management and software integration. He explains: “As packaging and label printers face the pressure to become more flexible and offer shorter production runs and lead times, driving waste out of the process becomes a top priority. Tailored dispensing systems, formulation software for automatic colour corrections and near-line table-top proofers to predict printing results provide the potential to significantly cut material costs, setup times and maintain tight quality targets. Efficient ink logistics therefore, are essential for a sustainable, efficient print workflow.”

 

Søren Maarssø will discuss the benefits of automatically controlling the ink supply to the press, by means of closed ink circulation. Ink supply systems regulate flow, pressure and viscosity, ensuring a constant, accurate ink density on the printed substrate, without air contamination. Their automatic cleaning facility allows complete ink change cycles easily in minutes. Additionally, sealed chamber doctor blade systems provide airtight closure and a clean, blister-free printed image with fast drying characteristics.

 

The automated enclosed ink supply system has been proven to deliver changeover times, higher ink yields, clean printing results at speeds of up to 800m/min (approx. 2600fpm), and a safer, emission-free working environment. 

 

“Flexo is capable of delivering quality comparable with other analogue processes – but price per unit is an important deciding factor for brand owners,” says Maarssø. “This joint presentation will provide valuable insight on how ink logistics, following ‘lean manufacturing’ principles, is instrumental in boosting the competitiveness of the process.”

Speakers include representatives from ink manufacturer Siegwerk, flexo tape supplier Lohmann Tapes, press control manufacturer BST eltromat as well as TRESU. In head-to-dead discussions, participants will explain how their developments in areas such as inks, ancillaries, substrates and process efficiency have improved the competitiveness of the flexo process. The discussions will be moderated by Dr. Sean Smyth, an independent consultant and analyst who works with Smithers Pira and acts as Group Technical Editor for Whitmar Publications.
 

Participating companies have achieved performance improvements by conducting joint research and testing programmes with TRESU, at the latter’s Innovation Centre, which houses the multi-station Flexo Innovator paperboard flexo line and iCoat coater for integration with digital printing presses.
  

Søren Maarssø, COO of TRESU Group, comments: “In an increasingly crowded retail environment where buying decisions are made in seconds, the brand owner is focused on making consumers choose their products by achieving shelf impact, creatively combining appealing artwork, with high quality coatings and finishes. At the same time, the optimum converting process for achieving this is driven by cost per packaging unit. As visitors attending our Speakers’ Corner talks will learn, TRESU’s Innovation Center has provided a hub for co-supplier innovation programmes that have enhanced the competitiveness of the flexo process for packaging applications.”
 

Siegwerk, one of the leading providers of printing inks for packaging applications, labels, and catalogues, will talk about its new inks and varnishes for paper and board applications. The company has introduced a water-based flexo ink series for paper and board applications named UniXYL, which is formulated with renewable, forestry-based components. UniXYL now belongs to TRESU’s certified ink series recommended for their printing presses. Siegwerk has also developed a high-gloss UV overprint varnish (OPV) for TRESU’s coating systems that integrate with digital printing lines for folding carton printing presses.   
 

For Lohmann, the flexo tape supplier located in Neuwied, Germany, the use of a TRESU print-simulation unit at its FlexoLAB has enabled the company to explore the behaviour of tapes in realistic working conditions and develop new products with optimised bonding properties. Lohmann will explain how trials resulted in the development its new DuploFLEX EB (‘Engineered Bonding’) range of double-sided adhesive tapes. The new range features the well-known foam carrier with double-sided flexible re-inforcement to maximize stability and offers better resistance to abrasive solvents commonly used in wide-web printing and seasonal atmospheric changes. The TRESU simulator played an important role in developing a tape that balanced plate stability at high speed with the ability to demount without damaging plate or sleeve – an issue of growing importance due to the increasing frequency of repeat orders. It also provided insight into the optimised cleaning processes. 
 

TRESU Group’s innovation and R&D manager, Christian Fogh, will explain how enclosed ink supply systems, featuring the company’s F10 iCon supply system and chamber doctor blades, provide the means for controlling ink circulation, eliminating leakage, raising ink yields and assuring uncontaminated ink supply at correct densities, at speeds of up to 600m/min.  
 

Furthermore, Siegwerk and Lohmann’s talks will focus on how their respective technologies contributed to a recent project with TRESU, named ‘Wrapping Ideas’, and aimed at producing high-quality folding boxes with enhanced efficiency and sustainability. Søren Maarssø comments: “Optimising performance of the flexo process depends on many variables. The collaborative teamwork enables us to look at the complete function and link each other in this process in the correct way. Together with our partners, we can present, not simply a stable flexo press, but a comprehensive programme for handling the machine, paper and tools in the correct way, to optimise uptime, efficiency and quality.”

Installed in May 2015, the workflow features a Xerox iGen 4 sheet-fed digital printer with a TRESU Pinta coater integrated inline and, near-line, a KAMA ProFold 74 folder / gluer and Kongsberg Plotter.
 

With its high speed, minimal setup times, automated features and variable data capability, the single-pass printing-coating line enables Alexir to enter short-run printing markets and offer solutions including samples on-demand and personalized packaging.Capable of up to 110 sheets / minute, the four colour (CMYK) iGen 4 press meets exacting quality targets with minimal manual intervention. It includes an inline spectrophotometer that automates colour adjustments and calibration, automatic density control, and high-definition linearisation that eliminates the need for grey-scale calibration.
 

The post-print coating operation, provided by TRESU's Pinta inline flexo coater, provides a layer of protection and enhances aesthetic appeal. A wide range of UV- or water-based finishes are possible that offer identical results to that of analogue print. These include matte, gloss, full surface, spot or fine-line effects.
 

The Alexir Partnership identified the need to add a digital workflow to its existing litho operation when it faced demand from emerging small food businesses, including farms that aim to sell into specialist niches or local markets. Claire Summersby, marketing manager at the Alexir Partnership, comments: “Before we invested in digital capabilities, we would get enquires for runs of perhaps 500 cartons, but our litho-printing operation was simply too costly for their needs. With the Xerox and TRESU production line and its minimised setup times, we can give these producers the fast supplies of appealing, high-impact packaging that result in retail listings and sales beyond the farmer’s market.”
 

Some of Alexir’s clients are luxury brands. One example is Life Shot 200, a natural, highly concentrated coconut kefir health drink containing 200 billion bacteria, sold in glass bottles that are packed in a Carton. Most jobs on the Xerox-TRESU printing / coating line are below 5,000 units, though variable data run lengths can be up to 100,000 units. Being viable for very short runs, digital print is a cheaper, faster and more realistic method of producing samples than using mock-ups.

 

Scott Beadell, digital production manager at the Alexir Partnership, comments: “With the seamless integration of the coater inline with the printer, we achieve the look and feel of the final printed result without extra logistics, material waste and setup times.  You can see immediately what the final product will look like.”
 

The TRESU Pinta is built to ensure productivity. Its patented sleeve technology that ensures stable, precise coverage at up to 5,000 sheets / hour. 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. After coating, the sheets are wheeled to the adjacent KAMA ProFold 74 gluer / folder or a Kongsberg plotter.

The press and coater cater for a wide array of paper stocks including coated, uncoated, textured, smooth, and speciality materials, and sheets of maximum cut size of 364mm x 660mm. Alexir specified the print / coating line to handle substrates up to 610 micron thickness to meet specialist demands.
 

Alexir’s foray into digital print resulted in their being awarded Investment Project of the Year at the 2015 UK Packaging Awards.

A light-weight carbon-fibre or ceramic chamber, MaxiPrint Concept comprises a chamber doctor blade, inking system and cleaning system. Suited for wide-web and corrugated flexo applications, the concept offers corrosion-resistance; fast, automatic internal cleaning; improved quality consistency and reduced ink loss.
 

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 shot mechanism maintains a low pressure, limiting water loss during the cleaning cycle. 
 

The 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 five minutes.  
 

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 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, also at fast speeds. The TRESU P-Line pneumatic clamping system also ensures fast, safe blade exchange within two minutes. 

 

Henrik Kristensen, vice president, TRESU Ancillary, comments: “Traditionally, the productivity of wide web printing presses has been compromised because of the intensive manual effort required to clean the complete ink system. This is especially the case in wide-web and corrugated printing when several printing stations are typically operated. MaxiPrint Concept programme, with its robust, stable construction, automates this process, reduces ink loss, shortens setup times and ensures quality consistency.” 
 

MaxiPrint chambers are available with a carbon fibre (CFC) or ceramic surface (CFX), offering protection against ink, coating media and detergents up to pH12. Weighing between 2.4kg and 4.1kg per linear metre (approx. 1.6lb – 2.74lg / linear foot) carbon fibre surfaces are lighter than the more economical ceramic alternatives, thus offering safest handling. TRESU has also extended its carbon fibre chamber doctor blade programme by introducing six-metre wide chambers, thus providing lightweight, corrosion-resistant solutions for all flexographic packaging printing applications.

 

The chambers are retrofittable and are compatible with closed-loop systems such as the TRESU F10 iCon Ink Control System.
 

TRESU will be exhibiting at drupa 2016, Hall 10, Stand D54.

At INFO*FLEX 2016 (Fort Worth, Texas, 7-8 March 2016), TRESU Group (stand 708) presents its light-weight, corrosion-resistant Carbon Fiber Chamber (CFC) doctor blade along with its F10 iCon ink supply system. Together, these two products from the TRESU ancillary program provide a fully automated, closed loop ink supply solution for a host of wide-web printing situations up to widths of 236.2in. (6000mm), thus ensuring consistent quality, improved productivity, lower emissions and significantly reduced operating costs.

Carbon Fiber Chamber: optimized corrosion-resistance and handling
TRESU’s carbon fiber chamber doctor blade offers protection against potentially corrosive ink, coating media and detergents up to pH12. Weighing between 1.6lb – 2.74lg / linear foot (2.4kg and 4.1kg per linear meter), they are lighter than the more economical ceramic alternatives, thus offering safest handling. A top-coated ink-repellent surface inside the chamber also enables easy, thorough cleaning after printing. Furthermore, curved inner surfaces maximize volume and facilitate faster discharge. Pneumatic (P-Line) clamping systems allow blade changeover within two minutes.

Available in widths from 63in. (1600mm) to 236.2in. (6000mm), the carbon fiber chambers are suited for water-based flexo printing applications, including corrugated board, flexible packaging, tissue, non-woven textile and industrial.

F10 iCon ink supply system automates flow control
The F10 iCon ink supply system automates ink pressure and viscosity in flexo printing machines. This, in turn, ensures a constant, accurate ink density on the printed substrate and prevents air from contaminating the ink chamber. The F10 iCon ink supply system circulates ink from the bucket to anilox roll at a controlled viscosity, flow and pressure. Stable circulation keeps the ink at constant viscosity to ensure consistent, precisely determined ink density on the printed substrate. The supply system measures flow within tight tolerances by automatically counting the pump strokes.

The energy-efficient system also provides thorough fully automatic cleaning, pumping unused ink in the chamber and hoses after printing back to the bucket, and completing an ink-change cycle within ten minutes. The F10 iCon’s ability to return inks for reuse in new jobs also delivers significant savings, cutting ink waste by as much as 110kg on a six-color job.

Scott Hibbs, president, TRESU Americas, comments: “TRESU is the only ancillary provider in the market to cover every step in the flexo ink supply cycle. That makes us uniquely positioned to offer closed-loop systems that are fine-tuned for the complete range of flexo printing applications and ink sets. The combination of TRESU’s carbon fiber chamber with the F10 iCon supply and washing system is a perfect example, providing the basis for predictable, consistent quality at faster print speeds; a sustainable, waste-free workflow, lower emissions and a cleaner, safer working environment.”

Organized by the Flexographic Technical Association (FTA), INFO*FLEX focuses on process control and converting equipment for the flexible packaging, label, folding carton and corrugated industry, and takes place at the Fort Worth Convention Center, Fort Worth, TX, 7-8 March 2016.

Explain the importance of process control

In an age of shorter production runs, high running costs and stringent quality demands, packaging printers are driven to cut out waste of the workflow at every opportunity. That is only possible if one has full control of the processes. This is especially true in flexo printing situations, where performance depends on many components working harmoniously.
 

Efficient management of the ink supply is crucial to the profitability, not to mention reputation, of the business.  Calibration of ink recipes requires the precision balancing of a tightrope act.  Uniform, accurate, high-gloss and uncontaminated print results depend greatly on tightly regulating the ink or coating medium’s flow, viscosity and pressure, from the bucket to the point at which it is applied to the substrate. The term for that regulation is ‘fully controlled ink logistics’.   
 

Why is manually controlling the ink unsuitable today?

The conventional method of ink regulation has been to manually top up the chambers with ink, but manual intervention and systems that expose the ink to the atmosphere have limitations. It is an intensive, ongoing task that is prone to error. Furthermore, open trays induce evaporation, and without a supply system, it is impossible to efficiently feed unused ink back to the bucket after production. Manual chamber cleaning is an arduous task, severely impacting productivity when several colours on a press are needed. On central impression presses, the ability to control is limited because many areas of the press are inaccessible or invisible without aids such as ladders.
 

Moreover, general market trends make a more sophisticated ink supply a necessity:

  • Achieving ink quality has become increasingly challenging:  brand owners accept no visible deviation in quality of package presentation, which increasingly must include more colours and more complex formulations. For example, package printers report that an average job today will contain two spot colours.
     
  • The trend towards shorter production runs in particular has made setup times and startup waste costlier. We hear from flexible packaging and corrugated board suppliers who have experienced a reduction in order sizes by 35% - from 70,000m² to about 45,000m² - in just three years, because retailers want to reduce stockholding costs by placing smaller orders more frequently. But whether one is producing ten thousand or ten million square metres, chambers need to be cleaned and recipes set with the same accuracy and dedication.
     
  • Thirdly, the need for cost control is compounded by the running cost of a flexo press, which can be anything from €250 to €1,000 per hour. Printers may be able to compensate for lost time by maximising speeds, in some cases to over 500m/min. But higher speeds can affect the ink rheology, and leverage the cost of scrapped material.
     
  • Fourthly, brand-owners expect their suppliers to maintain safe, environmentally responsible practices, not least to protect their reputation as a ‘sustainable’ supplier.

It follows, therefore, that to meet productivity, quality and sustainability expectations, today’s printer must have a professional, automated system in place to regulate the supply of ink from bucket to press, and maintain that delicate balance at all times.
 

What are the opportunities for improvement in the workflow?

It’s generally accepted that the key benchmarks for measuring the impact of the ink supply on overall performance are production time, consumption and man-power. By closely studying the workflows of Danish wide-web Flexo printers using the manual ink supply method, TRESU gained insight into where the opportunities for improvement existed.  Over seven months in 2014, we measured performance at seven stages of the process from preparation to finishing, in terms production time and consumption.
 

Production Time

The average time spent at each stage of the workflow for each press studied was as follows:  

 Stage of workflow Hours Percent
 Print preparation 38.84 1,11
 Start-up of new job 155,85 4.35
 Start-up of repeat job 539.59 15.06
 Colour adjustment 431.35 12.04
 Printing 1962.79 54.79
 Finishing the job 452.89 12.64
 Total 3582.31 100


 

The study showed plenty of room for improvement:

  • A mid-to-wide web flexo press typically runs at about 55 percent efficiency, with the remaining 45 percent being lost to setup times.
  • 27% of time was lost to adjusting viscosity, flow and pressure for repeat job start-ups and cleaning after production.

Time lost depends on the number, accessibility and weight of components that must be replaced or cleaned during or between jobs. It can take up to 45 minutes to clean each chamber, and several minutes to replace a doctor blade without a safe release and slot mechanism for example.
 

Consumption

Through management reports it was possible to identify how a lack of control of ink supply resulted in overconsumption of substrates, inks, cleaning fluids and energy: 
 

Substrates, the costliest form of consumption, especially for mid- and wide-web printers, account for between 60 and 90 percent of total waste. Without satisfactory ink control, paper or film can be lost because of:
 

  • Start-up waste, due to excessive ‘trial-and-error’ recipe calibration
  • Splashing
  • Costliest of all: material rejects resulting from blistering or shadow printing.

Ink and additives account for up to 20 percent of waste costs. In situations where the ink or coating medium is exposed to the atmosphere, waste results from:

  • Foaming
  • Inability to return inks to the bucket at the end of the production run. This can result in up to 20 litres of waste per chamber / unit
  • The need to constantly top up ink trays with ink or extenders due to evaporation, which is also a serious health and fire hazard.

Cleaning fluids, comprising water, solvents and detergents, account for 5 percent of costs. Energy, accounting for 1 – 2 percent of all costs, becomes more expensive in solvent ink situations, where air-driven pumps are necessary because cheaper, electrically powered pumps are prohibited because they pose a risk of explosion.

 

What does this experiment teach about optimising ink supply?

The experiences of our sample of Danish packaging manufacturers clearly show that careful consideration has to be given to a design of the supply system. That design should offer:

  • An enclosed system that allows no interaction between the ink and atmosphere at any time
  • Automation of controls and ink recipe setups
  • Reduced maintenance
  • Easy, safe access

For this, and because of their reliability, speed and accuracy, automated ink controls, featuring ink supply systems that pump ink or coating into the press, and chambered doctor blades that deliver the medium directly to the anilox roll cells, are essential on today’s presses.

How does the system work?

The key to control is enclosure of the ink system: this allows the harmonious, precise regulation of flow, pressure and viscosity, which in turn determines ink density, uniformity of coverage and dot gain.

The solution for that regulation comprises an ink supply system, connected by hoses to a sealed chamber doctor blade. These components must be seen as a whole due to their interdependency: the supply system automatically replenishes the chamber at finely calibrated rates, as the rotating anilox roll sucks the ink into the cells.
 

Ink Supply Systems

The software-powered supply system is the measurement and control device. Its functions illustrate the interrelationship between flow, pressure and viscosity.
 

Flow is measured by counting the pump strokes, multiplied by a stroke volume that can be estimated to an accuracy of 2.5 percent. An ink supply system typically has a variable flow range, from 5 to 30 litres per minute. 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 supply system regulates pressure based on measurements at the chamber inlet and compensations for variations in chamber lengths and ink viscosity. Pressure is maintained by maintaining the chamber depth. The operator raises the pressure so a wall of ink forms at the point where the rotating cells meet the blade. This stops air bubbles from entering, thus preventing the foaming that can result in blistered print effects. 


When the flow has been stabilized, the air regulation valve locks the air pressure to the pump. Since both the pressure inside the chamber and the air pressure to the pump are stable, only a change in ink resistance can change pumping frequency. Ink resistance, measured in viscosity, is determined by the supply system’s software and is based on a known pumping frequency. Thus, the supply of ink is maintained without human intervention.
 

Specially developed software not only controls flow but stores viscosity, flow-rate and pressure data for each job for easy recall. According to our survey, the savings potential from this is significant, as more than one-seventh of down-time resulted from manually preparing repeat jobs.  
 

The supply system also assures an accurate way of returning inks to the bucket and fast, thorough chamber cleaning, without manual intervention.

A cleaning system ensures the chamber is clear of residue, so ink is removed from the system. Cleaning cycles for solvent inks, e.g. on an eight colour press, takes up to ten minutes; for aqueous inks, 10 - 15 minutes are needed. Solvent consumption during cleaning amounts to 10-15 litres over two cycles. If water is used consumption of 20-30 litres less than one litre of detergent is usually needed. Also, because of its flow measurement assures accuracy to one litre, the supply system can safely return up to 90 percent of the ink or coating medium to the bucket after production. 
 

Savings in material waste and downtime are enhanced when several colour stations are involved. For example, a Jutland-based corrugated preprint supplier estimates it will save €40,000 annually as a result of retrofitting a six-colour CI Flexo press with an enclosed chamber doctor blade with automated supply system. They are able to return 19 of the 20 remaining litres on each colour station of ink back to the bucket after every job. 
 

Chamber doctor blade

The chamber doctor blade features a sealed, airtight chamber into which ink is pumped and circulated. Blades feature one at the top and bottom of the chamber wall. The wall formed by the two blades creates the closed environment, thus allowing controlled consistent ink metering, prevention against leakage and easier cleaning or job changes.
 

The two thin blades make contact with the surface of the anilox roll. One blade prevents the ink from escaping the chamber, the other metres the ink from the non-cell areas, so the exact desired ink / coating volume is transferred, making the fountain roller redundant. Anilox cell volume determines ink or coating lay down, ensuring consistent results, without intervention. Carefully positioning the blade at the anilox roller minimises blade wear, reducing maintenance costs, and ensures a uniform transfer in the cross direction.
 

Together with correct angling of the doctor blade which prevents air from getting trapped, a rubber seal system forms a perfect airtight closure and stops ink leakage from between the anilox roll and the chamber.        
 

A clamp allows the slotting of doctor blades into position, and easy release, keeping changeover times as low as one minute. Advanced systems include a fully automatic means of cleaning the chamber hoses and anilox roll on the press.    
 

Doctor blade systems are adapted according to the print width and ink / coating volume required. Variations range from closed-cassette chambers for label presses, to 3500mm-wide types for corrugated board printing and even wider.

What are the options?

Software-driven ancillary equipment plays a significant contribution to achieving uniform quality and driving waste out of the ink workflow, alongside dispensing and proofing equipment.
 

There are various degrees of control. Control of flow, pressure and viscosity should be considered a minimum requirement. Depending on budget and production volumes, additional control of ink consumption, temperature, pH levels, weight and cooling offer value.
 

What are the factors determining a retrofit?

Ink supply systems can be retrofitted into existing presses, by a supplier that is capable of sound project management. Such modernisation exercises can bring presses aged in excess of 20 years to the latest standards of productivity. A smoothly running modernisation programme depends on the supplier working closely with the customer's technical staff to know the specifications and understand its operation. These include the connections for waste, cleaning, water and solvents; the type of electrical power and air supply; the age of the machine may also necessitate a bespoke design.
Furthermore, extreme height may require additional ink pumping stations. 

 

Quality benefits

Controlled printing and coating results in significant quality benefits:

  • No contamination of air in the chamber, meaning blister-free print results
  • High gloss values, meaning better reflection

Productivity and Waste benefits

  • Ability to achieve high quality-print at faster speeds
  • Automatic recipe presets ensure quality is ‘right first time,’ avoiding ‘trial-and-error’ on-press calibrations that waste materials in startup phase 
  • Consistent coverage of the substrate with a uniform ink / coating thickness, requiring less energy to dry and delivering higher ink yields
  • Manual intervention eliminated, so operators can focus on high-value tasks
  • Savings of up to 19 litres’ ink / coating medium per chamber, thanks to supply system’s ability to return chamber contents after printing
  • Elimination of evaporation improves ink yields, reduces emissions and reduces health and fire risks
  • Setup times cut due to easy recall of ink recipe pre-sets, automatic chamber cleaning and fast, safe blade-change. Benefits are magnified on presses with several colour stations
  • Cleaner and safer operating environment, with less spillage and equipment in the vicinity of the press

In conclusion, ink logistics is the control of the ink through the supply chain, from the ink manufacturer’s container to the point when it is applied on to the packaging substrate.

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 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.

Located at point of embossing, the register guidance system ensures synchronisation of the printed pattern with the crease in the centre of the napkin, at speeds of up to 400 metres per minute (approximately 2000 pieces per minute). Using the converting machine interface signals as point of reference, the control module influences the servo motors to ensure accuracy is maintained on-the-fly throughout the production run. Servo drives ensure automatically controlled, precise print speed and ink flow, so that operation without in-house flexo experience or handling is possible.


The integration unit includes TRESU's F10 iCon ink supply system with automatic cleaning, to constantly feed the printing units and maintain optimum viscosity, temperature and pressure. 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. 


The system is optimised for fast job changes. 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 ability to seamlessly integrate the printing operation into the existing converting and assembly line means that customers can avoid the costs and lengthy lead times associated with outsourcing.


‘TRESU collaborated closely with the customer's research and development division at every step from the concept stage, to customise the machine to suit production requirements and skills levels,' stated Mr. Sander.


'The projects have been a large success for the customers, with integrations of our high level printing technology into a two-digit number of hygiene converting lines at locations in Europe, USA and Mexico. From TRESU's perspective, we are proud to have developed the requested solution on time despite demands on safety, process technology and a tight time frame.'

This Autumn, TRESU Group demonstrated the productivity, speed and efficiency of its Flexo Concept press for corrugated packaging, when it collaborated with Sappi to promote the ultra-white and strength properties of the speciality paper manufacturer’s Fusion® topliner.

Designed specifically for use with and on corrugated board, Sappi Fusion is an ultra-white virgin fibre topliner, for bag-in-box and gift-box packaging applications. Fusion features an extremely bright white and flat surface after lamination. Prints and all types of print finishing are reproduced with an unprecedented level of quality and brilliance. Fusion consists of primary fibres, providing further advantages in addition to whiteness and glue savings.  With precise folds and no discernible breaks, homogeneous packaging and displays can readily be constructed.  In addition, Fusion is fully ISEGA-certified for direct contact with food. Fusion’s industry-leading ISO whiteness values of up to 125 make it ideal for food, beverage and cosmetics applications.


 

To demonstrate these benefits, TRESU Group and Swedish converter FrontPac worked together to respectively print and produce samples of three-layered gift boxes featuring Sappi’s 180gsm high-white Fusion topliner. The topliner was printed at TRESU's Technology Centre in Kolding, Denmark, using five colours plus UV spot-varnish, then cut into sheets inline on TRESU’s Flexo Concept press. Running at speeds of 400m/min, the press maintained precise register while achieving 175lpi with minimal calibration or waste.


 

The sheets were then delivered to the Malmö (Sweden)-based printing house FrontPac, where they were litho-laminated on to a 110gsm E-flute liner and a 180gsm inner board and converted into gift boxes. Wiebke Perrey, marketing communication specialist at Sappi, comments, “With their proven expertise in high-performance presses for folding cartons, TRESU was the natural partner in our mission to demonstrate Fusion's aesthetic benefits and potential for supply chain savings. The TRESU Flexo Concept press exploits Fusion's printability to the full. The result is a pristine corrugated package presentation with flexographic quality that is indistinguishable from offset, and produced in a simplified workflow.”


 

TRESU's Flexo Concept is a high-speed flexo press for web applications between 900 and 1400mm in width with a wide range of complementary print and converting processes according to customer needs. These can include cold-foil, laminating, embossing, rotogravure and rotary sheeting. Configured as either a roll-to-roll or roll-to-sheet press, the Concept provides a high performance single-pass solution for a host of high end packaging applications.


 

Allan Sander, vice-president, TRESU Solutions, states, “Our collaboration with Sappi has enabled us to demonstrate the Flexo Concept's versatility as a web-fed single-pass inline solution for many high-end board converting applications. We are delighted with the outcome of this project and are excited to be sharing it with attendees at FachPack 2015.”


 

Each of the Concept’s flexo stations comes with TRESU's sealed chamber doctor blade systems that ensure direct, uncontaminated and pressure controlled ink transfer, resulting in optimised drying efficiency, uniform ink deposits and higher gloss values. Setup times are reduced thanks to long-life doctor blades that are exchangeable in one minute. Martin Enocson, managing director, FrontPac, comments: “Fusion has generated strong demand from our customers in such diverse markets as bag-in-box beverages, luxury goods, cosmetics and automotive parts. It brings stunning looks on the shelf and runs smoothly on the filling line. We’re excited by this collaboration as it gives us the chance to show this paper’s potential for strong branding and reduced system costs.”

TRESU Carbon Fibre Chamber Doctor Blade Programme

The TRESU Ancillary division’s enclosed, automated systems optimize control of ink / coating flow, pressure, viscosity and temperature, thereby minimizing manual intervention, raising productivity and maintaining quality consistency throughout the printing run. 

Featuring a patented rubber seal system, TRESU’s sealed, pressure-controlled chamber doctor blade systems offer airtight closure, eliminating the chance of leakage, escape of fumes or ink degradation. Furthermore they enable a direct, foam-free and uniform transfer of ink / coating to the anilox cells. This ensures a clean, blister-free printed image with fast drying characteristics, better reflection and higher gloss values, whether on paper or film. Pneumatic (P-Line) or eccentric (E-Line) clamping systems allow changeover of stainless or blades within two minutes.

 

TRESU’s chamber blade program is tailored for label, packaging and industrial flexo printing situations. For narrow-web printing, the closed-cassette FlexiPrint Reservoir needs no pump and operates at press speeds of up to 300m/min (984ft/min). For wider webs, TRESU new program of lightweight carbon fibre chamber doctor blade systems offer improved chemical resistance, optimised flow and safe, easy handling in virtually all flexo printing situations. The carbon fibre composition gives the chamber high-strength qualities, enabling a relatively low weight of between 2.4kg and 4.1kg per linear metre (approx. 1.6 lb – 2.74 lb per linear foot), thus easing chamber exchange.  The inside of the chamber features a top-coated ink-repellent surface. This offers extra protection against ink and detergents with high and low pH-values and ensures efficient, thorough cleaning after job completion. Furthermore, curved inner surfaces maximize volume and facilitate controlled discharge. The chamber’s design also enables ink and coating circulation in relatively low volumes.

 

F10 iCon ink supply system

For common impression flexo printing situations, the F10 iCon ink supply system automates ink pressure and viscosity in flexo printing machines.   This, in turn, ensures a constant, accurate ink density on the printed substrate and prevents air from contaminating the ink chamber.

The energy-efficient system also provides thorough fully automatic cleaning, removing ink and residue from the chamber, achieving a complete ink change cycle in five to ten minutes.

 

Henrik Kristensen, vice president, TRESU Ancillary, comments: “As demands grow for shorter production runs, and exacting colour standards, the need to optimise the ink circulation will only become more acute.  Our ancillary systems answer this need by providing a means of controlling the flow from the bucket to the anilox roll, in virtually all flexo printing situations.”
