Abstract

Eine mit Laserlicht arbeitende Druckplatten-Beschriftungsvorrichtung (1) zur Beschriftung einer ebenen oder einer auf einen Druckmaschinenzylinder (2) aufgespannten Druckplatte (4) besitzt eine oder mehrere Druckplatten-Beschriftungseinheiten (5), deren Laserdiodeneinheiten (10) im Gegentakt mit einem in der Nähe der Laserdiodeneinheiten (10) angeordneten Heizelement (18) betrieben werden, um dadurch die Temperatur der Laserdiodeneinheiten (10) während des Beschriftungsvorganges im wesentlichen konstant zu halten.

Figure 00000001
A printing plate labeling device (1) working with laser light for labeling a flat printing plate or a printing plate (4) mounted on a printing press cylinder (2) has one or more printing plate labeling units (5), the laser diode units (10) of which are in push-pull with one in the vicinity the heating element (18) arranged in the laser diode units (10) are operated in order to thereby keep the temperature of the laser diode units (10) substantially constant during the labeling process.
