ABSTRACT:
A lithographic ink and moisture control system is provided for maintaining copy quality over a wide range of operating and environmental conditions without special operator assistance. The control system, among other things, momentarily increases the moisture feed rate each time ink is added to the system to maintain a substantially constant ink/moisture balance at the master, particularly under high coverage conditions.
