KEYLESS INKING USING SUBTRACTIVE AND CLEAN-UP ROLLERS

摘要

Keyless inking systems and methods are disclosed which employs a main form roller (202) and a smaller clean-up roller (206), both in contact with a rotating print plate roller (204). Separate application and subtractive roller systems control the ink film on the form roller (202). The clean-up roller (206) removes residual ink from non-image areas on the printing plate roller (204). The clean-up roller (206) is in ink communication with the main form roller (202) through a vibrating roller (208). Mechanisms are provided to selectively engage and disengage the various rollers.
