ABSTRACT:
A system for supplying dampening fluid to a lithographic press dampening system. The system prevents dampening fluid starvation at a metering nip located between dampening system rollers, and minimizes contamination of the dampening fluid in the dampening system. A pre-determined distance is maintained between (1) the surface of a roller partially immersed in dampening fluid and (2) a fluid collection pan, so as to remove contaminants from the system. Sensors are used to determine the proper level of dampening fluid within the system to avoid nip starvation.
