Coating technology for an efficient single pass digital folding carton workflow
For digitally printed folding cartons and commercial products, a varnish layer over the substrate or underlying design gives essential protective qualities and added-value appeal.
TRESU DigitalSolutions offers complete workflows that enable digital printers specialising in these applications to integrate the coating operation seamlessly in a single-pass process, with minimal logistics or waste. We provide every step in the coating workflow: modular coating systems based on flexo and inkjet technology, plate and sleeve imaging equipment, varnish media, circulation systems, sleeve systems and after-sales support.
TRESU’s modular coating systems apply full-surface, spot and line varnishes inline with the latest digital printing presses from leading OEMs. They work with a wide range of UV-curable and water-based coating media, to create gloss, matte, soft-touch and metallic effects. These coating media are specially formulated by TRESU to perform in the unique conditions of the digital line.
TWIN coaters, featuring two coating stations in one system, enhance creative branding opportunities by enabling a combination of high-value varnish effects. For added flexibility, inkjet coating units enable variable application of spot varnish – an ideal choice for variable data applications.
TRESU coating systems come with a host of features to ensure optimum quality and efficiency at up to 5000 sheets / hour, and productivity when managing with short runs. Flexo-based coaters include a patented sleeve system to eliminate ‘bounce’ and achieve precise register at top speeds. Circulators ensure optimum flow characteristics of even the most sensitive media. And setup times are kept to a minimum thanks to automatic chamber cleaning and fast sleeve exchange.
Furthermore, with our iCut sleeve cutter, imaging of sleeves for the coater is simple and fast. TRESU’s complete coating programme provides the ideal complement to a lean digital production line for competitively offering short-runs, variable information packaging and test marketing situations. It adds value to a wide range of applications, including pharmaceuticals, media, food and confectionery, cosmetics, consumer electronics, promotional products and gifts.
