Ashland Specialty Ingredients, a commercial unit of Ashland Inc, has obtained certification by the Rochester Institute of Technology (RIT) for 13 UV and water-based overprint varnishes within the PureRad and PureKote overprint varnish (OPV), product lines. The products are now commercially available for use with HP Indigo narrow web printing presses.
The print-receptive coatings are clear, better fixate ink on a variety of substrates, and also protect it from aesthetic and functional damage during the intended life of the graphic.
PureRad and PureKote overprint varnishes offer improved adhesion to HP Indigo ink coupled with high performance scratch and chemical resistance. The commercial offering includes two new products, PureRad 53830 high gloss, heat-resistant OPV and PureRad 53860A high gloss UV resistant OPV.
‘Ashland offers one of the broadest array of RIT-certified overprint varnishes for use with HP Indigo to meet the increasing manufacturing and application demands for digital printing and mass customisation,’ said David Hatgas, global director, packaging and converting, performance materials.
