Pulp Diction

What about that disappointing curl that can put a dent in your otherwise flawless piece? Bob Hieronymus, Georgia-Pacific senior marketing project manager, communication papers, reports that mills are adjusting papers to better meet the atmospheric demands of digital print engines.

"For instance," Hieronymus explains, "the high temperature fusing process that takes place during toner adhesion can cause paper to curl. By reducing the moisture content for digital presses to 4.5 percent, as opposed to 5.5 percent commonly used for offset paper, the risk of curling is greatly reduced. A smaller moisture percentage also allows for better control of electrostatic conductivity, which improves toner adhesion."
