ABSTRACT:
A system for predetermining appropriate settings for the ink flow control devices of a printing press in dependence upon the average inked area in each of a plurality of image zones whose ink supply rate is controlled by a respective one of the ink flow control devices. An image-bearing member such as a lithographic printing plate is imaged onto an electronic camera tube where it is scanned. Electrical signals from the camera tube are integrated for each ink control zone and the resultant signals indicate the appropriate settings for the ink flow control devices, which can be remotely controlled. Spatial variations in illumination are compensated; output signals are automatically normalized.
