PRESS
Uncoated, uncomplicated

Uncoated papers printed with inks that dry oxidatively should have a pH value of about 5.5, since acidic stocks can lengthen drying times—as much as four times longer than in jobs with coated papers. With this in mind, avoid stacking uncoated sheets so high that they begin to take deposits from darker motifs or larger ink surfaces on the next page. Because of dust accumulation, the press (including inking units and blankets) should be cleaned regularly.
