Printing unit for printing on substrates using an intaglio printing process

Abstract

The invention relates to a printing unit for printing on a substrate using an intaglio printing process, comprising a form cylinder with a counter-pressure cylinder forming a printing point and which includes an image-forming pattern of first depressions on its circumference, and an inking unit for inking the pattern of depressions provided on the form cylinder, wherein the inking unit comprises a first inking cylinder whose outer surface can be supplied with printing ink by an inking device, and a second inking cylinder interacting downstream with the first inking cylinder, which interacts directly or via a third inking cylinder with an ink collection cylinder, which in turn interacts downstream with the form cylinder, and wherein the first inking cylinder comprises a cylinder base and an ink transfer form designed in the form of a sleeve.which is detachably attached to the cylinder base in its operational state. The cylinder base is segmented in the area of ​​its outer circumference and has several individual circumferential segments arranged one behind the other in the circumferential direction, extending axially and mounted at variable radial distances to the cylinder axis on a one- or multi-part inner cylinder body.
