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.
