Kolding, Denmark - TRESU will exhibit a complete workflow for integrated inline coating and metallic finishes on HP Indigo presses, for folding cartons and synthetic materials, at Dscoop Phoenix (1-4 March, 2017, Phoenix, Arizona, USA). 

Dscoop is a convention that brings over 2,000 users of HP Indigo digital printing technology together with partners and vendors, to share ideas and learn about new technologies, services and opportunities. The four-day program includes an exhibitor hall from partner suppliers and a conference program with an assembly of speakers that aim to inspire new ways of thinking and approaches to business. 

TRESU provides single and dual-coating machines, coating circulators, sleeve cutters and specially optimized consumable products including coating material and tapes, so digital printers can adopt a fast, efficient coating workflow.

Live demonstrations of the TRESU iCoat flexo coater, working seamlessly with the HP Indigo 30000 digital press, will show how added-value post-print varnishes can be applied at speeds of up to 4600 sheets / hour. The same production line will feature a new compact flexo printing unit, integrated to a peristaltic pump, named TRESU Flexo Kit, for rapid application of high-gloss metallic, aerodyne, and other special effect coating finishes. Fast changeovers of sleeves and automatic chamber cleaning on both units minimize setup times to within five minutes. 

The company will also feature its own iVarnish line of UV and water-based coating material that is specially formulated for the digital printing line. At Dscoop, TRESU will be presenting new varnishes with improved adhesion properties so that plastic as well as board substrates may be run. One potential application is the retail loyalty card.

Scott Hibbs, President and CEO of TRESU Americas, comments: “Coating is a vital complement to the digital printing process, generating enhanced aesthetic appeal and product protection. The perfect compatibility of TRESU equipment with HP Indigo digital technology provides a single-pass process for folding cartons with precise register, minimal material waste, manual input and logistics. This opens opportunities to offer short-run and variable data solutions that enhance value in the packaging supply chain, such as branding solutions for niche markets, faster time-to-market, cost-effective product launches and reduced stock-holding costs. Dscoop offers visitors the chance to see these possibilities first hand running live jobs.”

Another TRESU innovation for the digital workflow and shown at the convention is TRESU iTape, a double-sided adhesive, developed in partnership with Lohmann Bonding Engineers, of Neuwied, Germany. Benefits are superior dot gain control and varnish transfer, and fast frictionless demounting eliminating the possibility of causing sleeve damage. 

In addition to the single coater exhibited at Dscoop 2017, TRESU also offers an iCoat 30000 TWIN, featuring two flexo coating units that enables the application of a combination of aesthetically appealing spot, line, matte and gloss varnishes. Also available is an inkjet coating feature called the TRESU iJet, for variable positioning of spot coatings. Integrated into the iCoat, up to 11 print heads can be positioned in the cross direction of the sheet to apply coating anywhere on the surface of the image.
