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, adjusts the ink and moisture feed rates to compensate for predicted changes in master conditions associated with the absorption of moisture by the master during the course of a copy run.
