ABSTRACT:
A control circuit for controlling ink supplied to the inking surface of an intaglio printing device includes a sensor for sensing voids in the ink on the inking surface. The control circuit provides a predetermined volume of ink to a reservoir when such a void is detected. A timer inhibits the control circuit for a predetermined time after each ink transfer to avoid overfilling the reservoir.
