The invention relates to an intaglio printing machine having a plate cylinder, and an impression cylinder which is equipped with an actuator for engagement and disengagement and can be adjusted by means of this actuator between an operating position resting on the plate cylinder and a position of rest removed from the latter. A wiping device has a wiping cylinder which interacts with the plate cylinder, and likewise can be adjusted by means of an actuator between an operating position, in which it rests on the plate cylinder with predetermined pressure, and a position of rest removed from the plate cylinder. The wiping cylinder is mounted in eccentric bushes and can be coarsely adjusted by means of hydraulic cylinders, by which the eccentric. bushes can be rotated, between its operating position resting on the plate cylinder and a position of rest removed from the latter. Additionally, a fine adjustment is provided, by which the change in spacing between the axles of the plate cylinder and the wiping cylinder, as a result of deflection of the plate cylinder occurring during the engagement of the impression cylinder, can be compensated. For this purpose, the hydraulic cylinders are each attached to a worm wheel which can be rotated by a worm spindle. Providing the fine adjustment of the worm spindle is a stepping motor, which is adjusted simultaneously with the engagement and disengagement of the impression cylinder in each case by a preselectable amount in either direction.
