Abstract

Vorrichtung zur Bestrahlung einer Druckwalze eines Laserdruckers oder dergleichen mit Licht umfassend mindestens eine erste Laserlichtquelle, Modulationsmittel (3) für die Modulation mindestens eines ersten von der Laserlichtquelle ausgesandten Laserstrahls (1) entsprechend zu druckenden Informationen sowie Abbildungsmittel (7) für eine der Druckwalze (8) entsprechende Abbildung des von der Laserlichtquelle ausgesandten modulierten Laserstrahls (5) auf einen vorgegebenen Ort (Auftreffpunkt 10) der Druckwalze (8), wobei durch den modulierten Laserstrahl (5) an dem vorgegebenen Ort (Auftreffpunkt 10) der Druckwalze (8) eine der zu druckenden Informationen entsprechende lokale Änderung der Druckwalze erfolgen kann, wobei die Vorrichtung Mittel zur Erzeugung eines zweiten Laserstrahls (2,6) sowie Abbildungsmittel (4, 7) umfaßt, mit denen der zweite Laserstrahl (2,6) gleichzeitig oder zeitlich kurz vor dem ersten Laserstrahl (1, 5) am gleichen Ort (Auftreffpunkt 10, 11) wie der erste Laserstrahl (1, 5) oder in räumlicher Nähe zu diesem auf die Druckwalze (8) abgebildet werden kann.
