摘要: A lithographic ink and moisture control system as 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 high moisture conditions which occur at several short copy runs, wherein significant moisture is introduced with each new master.
