Problems solved by technology

Thus, for example, for printing groups with a large axial width of the cylinders, in particular the plate cylinder 13 and the transfer cylinder 14, there is the problem that such cylinders with a large axial width have a tendency to deflect, wherein this This deflection may impair print quality
In this case, the transfer plate 23 has a tendency to increase wear

Abstract

The invention provides a printing unit for a printer, which comprises an inking unit, a transfer cylinder (14) and a forme cylinder. The inking unit is used for applying the printing ink onto at least one printing form on the forme cylinder. The printing ink positioned on the basis of each printing forme has at least one on the transfer cylinder (14) as a blanket or blanket plate (23) formed transfer form on a substrate to be printed (21) coatable, wherein between the transfer cylinder (14) and the or each blanket or between the transfer cylinder (14) and a metal support (24) of the or each blanket plate (23) a contact structure (28) is positioned, that is either with the transfer cylinder (14) or with the metallic support (24) of the respective rubber blanket plate (23) connected.

Description

technical field [0001] The invention relates to a printing couple of a printing machine according to the preamble of claim 1 . The invention also relates to blanket plates. Background technique [0002] figure 1 A schematic view of a printing color set of a printing press, ie an offset printing color set of a web printing press, is shown from the prior art. figure 1 The illustrated printing set 10 comprises an inking set 11 , a dampening unit 12 , a forme cylinder 13 and a transfer cylinder 14 . At least one printing forme 15 is arranged on the outer circumference of the printing form cylinder 13 . By means of the inking set 11 , the printing ink and by means of the dampening unit 12 , a dampening solution can be applied to the or each printing plate 15 positioned on the printing plate cylinder 13 . With regard to the inking color set 11 , an ink fountain 16 , an ink fountain roller 17 and a plurality of further inking unit rollers 18 are shown. With respect to the damp...
