Coated vs. Uncoated Paper

Switching to uncoated paper at PCOM required a few modifications. Chalking was one of Gray's challenges, and he had concerns about scuffing as the uncoated sheets went through the bindery process. He has found that, in dealing with uncoated paper, he must have more inks formulated to avoid chalking and enhance drying. And he has to adjust the screen—sometimes to 250—to compensate for dot spread.
