Embodiment Construction

[0019] The single figure shows a printing press 1 with at least four printing units 2 for four-color printing. The printing press 1 is a sheet-fed printing press and is constructed in a tandem configuration. For reasons of simplification, the feeder and delivery of the printing machine 1 are not shown in the figure. The printing units 2 are lithographic offset printing units and each comprise a printing cylinder 3 , a blanket cylinder 4 , a dampening unit 5 and an inking unit 6 . Furthermore, each printing unit 2 also includes an impression cylinder; however, these impression cylinders are not shown for reasons of simplification of the illustration.

[0020] The inking units 6 are anilox inking units and each comprise an inking roller 7 , an anilox roller 8 and an ink supply 9 which rests on the anilox roller 8 . The inking roller 7 and screen roller 8 of each printing unit 2 rest against each other without a pillow ring, ie the two rollers are not provided with a pillow rin...

Abstract

In a method for controlling the temperature of a press which has an applicator roller and a screen roller, the screen roller has its temperature controlled at different temperatures and the applicator roller has its temperature controlled at a constant temperature.

Description

technical field [0001] The invention relates to a method for regulating the temperature of a printing press. Background technique [0002] DE 197 36 339 B4 describes a printing press in which the temperature is adjusted for an screen roller and an ink form roller. [0003] DE 85 33 004 U1 describes a printing press in which the temperature is regulated with preselectable temperatures for an engraved roll. [0004] EP 0 870 609 A2 describes a printing press comprising offset printing units with anilox inking units (Anilox-Farbwerken). [0005] The problem of ink control being influenced by a plethora of influencing factors has not been solved by the mentioned prior art. Contents of the invention [0006] It is therefore the object of the present invention to specify a temperature regulation method by which the ink control can be simplified. [0007] This task is solved by a method for regulating the temperature of a printing press. In the method according to the inventi...
