摘要： 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).

摘要： OOptical scanners (18, 19) mount to a press (1 to 8) and provide information to a register control system (15, 16, 17, 20) which automatically maintains color-to-color register. The same information is processed to provide signals to a scanner interface circuit (17) which controls the position of the optical scanners (18,19) to insure that they track the register patterns on the moving web (6).
