TRESU Group highlights broadened ancillary programme for automated flexo ink control, plus iCoat 30000 TWIN coater for digital folding carton at Labelexpo Europe 2015

Tuesday 14. July 2015 - At Labelexpo Europe, TRESU Group (Stand 7D53) will showcase flexo ancillary solutions that automatically control ink circulation, thus reducing makeready time and assuring uniform quality. Furthermore, the company will highlight its coating technology for digitally printed folding cartons via a table-top presentation.

TRESU Carbon Fibre Chamber Doctor Blade Programme
The TRESU Ancillary division’s enclosed, automated systems optimise 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 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 programme 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.”
TRESU iCoat Twin Tabletop Presentation
TRESU’s iCoat 30000 TWIN applies two varnish coats – full, partial or spot – to digitally printed folding cartons. Integrated inline, it contributes to a seamless single-pass sheet-fed print / coating operation.
Specifically designed for inline integration with the HP Indigo 30000 Digital Press, TRESU iCoat 30000 TWIN includes two flexo units capable of applying spot, partial or full surface coating immediately after the printing stage. This seamless single-pass sheet-fed print and coating operation offers an effective way of enhancing functionality and aesthetic impact, with multiple combinations of UV-curable and water-based coatings, in a single process. This means reduced logistics, material waste, setup time and handling.
Capable of running at a minimum of 5000 sheets / hour on board substrates between 180gsm (121.6 lb) and 500gsm (337.8 lb), TRESU iCoat 30000 TWIN also features corona treatment, quick-change sleeve technology and the ability to switch from UV to aqueous varnish within a few minutes.
