Did you know one of the most important aspects of a high-quality printed document is a high-quality sheet of paper? Just ask Shannon Gittermann, a process engineer at our Johnsonburg Mill. She leads the effort to optimize sheet formation to ensure premium printing outcomes.
One of the biggest challenges to achieving a clean and uniform print job is picking — the appearance of small white specs in the printed colors. Picking happens when tiny bits of the sheet pull away as color is laid during the print process.
“A lot of our customers use our high-quality paper for printing forms, brochures and flyers,” Gittermann says. “We want to ensure they always get good solid color when they print, so we have a process to test for picking and help guard against it.”
Our technicians use the wax pick test, which uses calibrated wax sticks to evaluate surface strength. The Domtar mills that produce Husky, Lynx and Cougar paper use this test as a predictor of offset printing cleanliness.
