Paper Plays Key Role in Production Inkjet Press Decision
Because paper is such a crucial part of any inkjet press decision, Mary Schilling, director of print quality analysis at InkjetInsight.com, gave a presentation analyzing trends in inkjet paper during the 2018 Inkjet Summit. After hearing from customers, she said, paper mills are introducing new inkjet papers, such as highly calendared stock, which provides higher print quality than inkjet-treated paper and better drying performance than inkjet coated. It has a smooth, slick surface, reminiscent of coated stock.
She discussed the benefits of applying pre-coatings on paper (e.g., it expands paper choices, slows ink absorption and increases print quality) as well as the challenges (e.g., higher costs, additional maintenance and the need for more drying capacity).
Schilling also talked about new high-viscosity UV ink chemistry, which can expand media choices and boasts minimum ink migration, no water/paper saturation and an expanded color gamut. However, those UV inks cost 10-15% more than aqueous inks and result in slower jet speeds and a longer cure time. They also yield a raised surface that can crack on the fold, she said.
Schilling encouraged the printers in the room to continue talking with the mills to let them know what they need in an inkjet paper.
"You guys are pushing the industry," she said. "Push harder."
