Abstract
A system for supplying dampening fluid to a lithographic press dampening system. A metering roller pair is arranged to form a metering nip such that dampening fluid cannot drain away in a circumferential direction when the rollers stop moving. The metering nip constitutes a reservoir capable of being replenished with dampening fluid so the metering rollers can deliver dampening fluid in a manner that prevents contamination. The system includes a pair of metering rollers having a nip at their junction and a sensor for controlling the supply fountain solution available for delivery to the metering nip.
