摘要

The offset printing process involves the simultaneous relative adjustment of the temperatures of the surface to be printed on and/or of the damping medium and/or the printing ink. The surface of the residual ink on the printing plate is cooled down by the wetting to such an extent that it is colder than the ink on the application roller. - The applied printing ink is somewhat colder than the temperature of the printing ink on its way to the zone of the application roller. This temperature is preferably room temperature. A temperature regulation unit (15) is used to cool the damping medium and/or the printing plate as well as at least one of the rollers (20, 21) of the inking system.
