ABSTRACT:
A plurality of ink pumps are mounted directly on an ink rail. The ink pumps are gear pumps, each having a D.C. motor associated therewith. Each gear pump delivers ink to a particular section of the ink rail from which the ink is then applied to a particular circumferentially extending segment of the ink roll corresponding to a column on the page to be printed. By controlling the speed at which the motor operates, the amount of ink pumped can be varied, and thus the amount of ink delivered to the roll can be varied.
