Coated vs. Uncoated Paper

With ink saturating more into uncoated paper, it takes more ink to print an uncoated sheet, he points out.

For instance, a coated sheet will run a black ink density of l.6 or l.7 compared to 1.1 for uncoated.

"When you run a coated sheet, you run less ink but get higher ink densities," he says. "When you switch to uncoated you've got to open up your ink dams a little bit."
