Impulse Press Simulation of a Gravure Printing Nip, 1990 International Printing & Graphic Arts Conference Proceedings
A hammer-and-anvil-type “impulse press”, originally used to study the wet pressing of paper, was modified to simulate the nip region on a high speed rotogravure printing press. This apparatus allowed fundamental studies of gravure ink transfer to be done at contact times approaching current commercial printing speeds. The effects of several variables on gravure ink transfer were studied. While the results showed similar trends to those of earlier studies done at slower printing speed, they indicate that capillary forces do not contribute significantly to ink transfer at high speed.
