Ink wiping system for an intaglio printing press

摘要

There is described an ink wiping system (100) for an intaglio printing press comprising a rotatable wiping roller assembly (102) for wiping 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 for wiping the surface of the printing cylinder (80), and a pressing device (130) disposed inside the cylindrical body (110) for exerting pressure on an inner surface (11 Ob) of the cylindrical body (110) and for adjusting 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) for adjusting the wiping pressure between the cylindrical body (110) and the intaglio printing cylinder at a plurality of axial positions.
