Abstract
A method for controlling the temperature of print bearer surfaces during printing in rotary printing machines. The print bearers are fastened in exchangeable fashion on the circumferential surface of print form cylinders. The surfaces of the print bearers are inked by inking form rollers. The temperature of the color-separation-guiding surfaces of the print bearers is controlled in such a way that narrower/broader printing and/or shorter/longer printing arising during the passage of the printed material through the printing unit is compensated per individual printing unit.
Claims7
A method for controlling the temperature of print carrying surfaces during printing in a rotary printing machine, which comprises:
- providing at least one printing unit having a print form cylinder with a circumferential surface;
- exchangeably fastening a print carrier on the circumferential surface of the print form cylinder;
- using at least one inking form roller to ink the print carrier;
- providing a targeted linear deformation of the print carrier;
- and
- during printing, controlling a temperature of a color separation-guiding surface of the print carrier to produce said targeted linear deformation to compensate for at least one printing effect selected from the group consisting of narrower/broader printing and shorter/longer printing that respectively arises during passage of printed material in each of the at least one printing unit.
