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.
