Abstract
There is described an ink wiping system (100) for an intaglio printing press comprising a rotatable wiping roller assembly (102) designed to wipe excess ink from the surface of a rotatable intaglio printing cylinder (80). The rotatable wiping roller assembly (102) comprises a rotatable hollow cylindrical body (110) having an outer surface (110a) positioned to wipe the surface of the printing cylinder (80), and a pressing device (130) disposed inside the cylindrical body (110) and designed lo exert pressure on an inner surface (110b) of the cylindrical body (110) and to allow adjustment of a wiping pressure between the cylindrical body and the intaglio printing cylinder (80). The pressing device (130) preferably comprises a plurality of pressing units (132) that are distributed axially along the inside of the hollow cylindrical body (110) to allow adjustment of the wiping pressure between the cylindrical body (110) and the intaglio printing cylinder at a plurality of axial positions along the length of the hollow cylindrical body (110).
