Abstract
A system for the continuous and automatic supply of a mixture of ink and dampening fluid to a lithographic press. The ink and dampening fluid are mixed and then pumped to the press fountain. The fluid mixture is sampled downstream from the mixing location and a signal is sent to control feed of ink and dampening fluid to the mixing location to ensure that the desired ratio of ink to water is maintained.
