Abstract
Abstract A printing press control system for controlling a press having a plurality of printing units each of which has at least two printing cylinders, with each cylinder having a plurality of plate positions and a plurality of column positions within each plate position. An ink supply system is associated with each printing cylinder in the press, and includes means for separately adjusting the ink supply rate at each of the column positions. The control system includes means for generating an electrical signal representing a selected printing cylinder, a selected plate position, and selected column positions at which the ink supply rate is to be adjusted, and a selected direction and magnitude for the adjustment to be effected in the ink supply rate. Press adjustments other than in the ink supply system can also be controlled. The control system further includes receiver means associated with each of the printing units and responsive to the generated electrical signals for enabling the adjusting means at the selected cylinder, plate position, and column positions. The receiver means also energizes the selected adjusted means in the desired direction until an adjustment of the desired magnitude is effected, and then automatically deenergizes the adjusting means.
