TRESU Launches IVarnish OPV Range


TRESU Digital Solutions has launched iVarnish, a range of proprietary water-based and UV-curable overprinted varnishes (OPVs). It offers enhanced protection, aesthetic appeal and converting efficiency for digitally printed folding carton applications.

TRESU iVarnish OPV is specially optimised to ensure a clean, productive coating in high-end digital folding carton applications. The TRESU iVarnish range is specifically formulated for the company’s TRESU iCoat and TRESU Pinta flexo coating systems, which offer inline spot and flood varnish application, following the printing stage. Properties include excellent slip angle for easy feeding of the substrate, rub resistance to ensure brand integrity is maintained, and viscosity characteristics for optimised curing and drying at speeds of up to 5000 sheets per hour on board substrates ranging from 180 and 500gsm.

The iVarnish OPV range includes UV-curable and water-based high-gloss, gloss and matte varnishes; additional water-based varnishes with German and Swiss Ordinance-compliant safety properties are available for food and pharmaceutical applications. Kim Krintel, senior manager Print Technology of TRESU Group commented, ‘The TRESU iCoat and Pinta inline coaters have generated global interest because they have brought significant productivity and cost benefits to the folding carton workflow. Based on TRESU’s expertise in flow control, iVarnish is fine-tuned to the unique conditions of the coater, its compatible substrates and components. As a result, the new range gives assurance of productive and clean application and pristine quality, in a wide range of end-user niches.’

Contributing to a lean, single-pass print-converting line, TRESU iCoat with iVarnish offers a simpler alternative to an offline workflow that requires stand-alone coating equipment. Market sectors targeted by TRESU Digital Solutions include cosmetics, pharmaceuticals, retail promotional packaging and foods.
