Getting the Most Out of Coated and Uncoated Papers

Coated paper's influence on ink drying would be how fast the paper absorbs the vehicle of the ink, which allows the remaining portion of the ink to stay on the surface and polymerize. The coated paper selectively pulls out the vehicle of the ink through the capillary action of the paper surface. The capillary action of the paper is directly associated with the pore size and volume of the paper surface. A paper that quickly sets up the ink will be good for ink drying, but if the ink sets up too quickly it can contribute to other problems such as picking and downstream piling.—Brian Fenner, NewPage
