Today, 4-color process—and to a large degree 7-color process—have become well-established, … Continued
When I was first learning how to run a press, one of the biggest things I could remember thinking was, “How am I supposed to know how these different anilox rollers print?” I would watch all the veteran operators switching out anilox rollers, and they knew exactly which one to drop into press for each … Continued
