Abstract: An apparatus and method for maintaining a minimum amount of ink in an ink fountain (10) of a printing press includes an ink fountain level sensor (28) and ink dispenser (26) mounted on a carriage (30) for lateral movement on a track (32) across the ink fountain. The carriage traverses the ink fountain. When the ink in the fountain develops a spot below a preset minimum level, a preset amount of ink is immediately dispensed upon detection of the low spot by the sensor.

Abstract: An ink management system for an offset printing press includes a cartridge of offset printing press ink, wherein the cartridge has an exit opening in one end through which ink is dispensed and an open end opposite said exit opening. A movable member is disposed within said ink cartridge for dispensing ink from said ink cartridge. Movement of the movable member dispenses ink into an ink fountain through the exit opening. The displacement of the movable member is determined in order to track an amount of ink dispensed during, for example, a printing run.

Abstract: The dampening apparatus and method provides automatic ink/water control for a lithographic printing press by means of a hydrophylic metering roll in a pan for fountain solution which contacts an oleophylic transfer roll. The transfer and metering rolls are free wheeling friction driven rolls which are driven in substantially a one-to-one surface speed ratio by friction between the transfer roll and a dampener form roll to cause the metering roll to provide an unmetered excess of dampening fluid from the pan to a nip with the transfer roll. The dampener form roll is positively driven from the drive system for the press plate cylinder at a one-to-one surface speed ratio with the plate cylinder and is a resilient oleophylic roll having a durometer within the range of 20 to 30 durometer. The transfer roll is harder and of different diameter than the dampener form roll with a durometer in the range of from 30 to 60 durometer.
