Multicolor ink transfer arrangement and method

摘要

Differently colored inks are applied in close proximity to each other during inking of an etched or engraved surface of a die or plate in a printing press. The spacing between the inks is controlled by the pressure of a transfer roller against the die or plate surface. The spacing can be reduced to effectively zero so that the inks effectively touch each other on the die or plate. Cross contamination of the inks when the transfer roller picks up the inks from a fountain roller is prevented.
