ABSTRACT:
A method of and apparatus for controlling the amount of ink and water supplied to the plate cylinder of a web offset press. The web offset press operates to print an image on a travelling substrate and the method includes the steps of: (A) monitoring a characteristic of the substrate; (B) changing by a known quantity the amount of ink supplied to the plate cylinder in response to said monitored characteristic; (C) monitoring the change in the characteristic after the step (B) to determine whether the density of ink supplied to the substrate has changed in response to the step (B); and (D) decreasing the amount of water supplied to the plate cylinder when the monitored characteristic does not change in response to the step (B).
