Claim:
1. An intaglio printing press comprising an intaglio cylinder and an ink wiping system with a rotating wiping roller assembly contacting a circumference of the intaglio cylinder for wiping excess ink from the surface of the intaglio cylinder, a rotational speed of the wiping roller assembly being adjustable with respect to a rotational speed of the intaglio cylinder, wherein the intaglio printing press comprises an adjustable drive unit, which adjustable drive unit is interposed between the wiping roller assembly acting as a rotating output body of the adjustable drive unit and a driving gear coupled to the intaglio cylinder and acting as a rotating input body of the adjustable drive unit, wherein the adjustable drive unit is designed to allow selected adjustment of a rotational speed of the wiping roller assembly with respect to a rotational speed of the driving gear, wherein, in an adjusting state of the adjustable drive unit, driving into rotation of the wiping roller assembly is adjusted by means of an adjustment motor of the adjustable drive unit to change the rotational speed of the wiping roller assembly with respect to the rotational speed of the intaglio cylinder, and wherein, in a non-adjusting state of the adjustable drive unit, the adjustment motor is inoperative and driving into rotation of the wiping roller assembly is performed exclusively mechanically via the adjustable drive unit, the wiping roller assembly rotating at a defined rotational speed with respect to the rotational speed of the intaglio cylinder.
