Abstract

Die Erfindung betrifft ein Verfahren zum Entbildern eines permanenten Bilds auf einer Oberfläche (12) einer wiederbeschreibbaren Druckform (11), insbesondere innerhalb einer Druckmaschine, wobei beim Löschen die Druckform um ihre Längsmittelachse drehend angetrieben wird. Erfindungsgemäß wird das Bild von der Oberfläche (12) der wiederbeschreibbaren Druckform (11) abgeschliffen, wobei hierzu vorzugsweise eine rotierende Schleifeinrichtung (14) an die Oberfläche (12) der drehend angetriebenen Druckform (11) angestellt und beim Schleifen an der Oberfläche abgetragenes Polymer von der Oberfläche der Druckform abgesaugt wird.

The invention relates to a method for deinterlacing a permanent image on a surface (12) of a rewritable printing form (11), in particular within a printing machine, wherein when erasing the printing form is driven to rotate about its longitudinal central axis. According to the invention, the image is abraded from the surface (12) of the rewritable printing forme (11), preferably a rotating grinding device (14) to the surface (12) of the rotationally driven printing forme (11) and abraded at the surface of the abraded polymer of the surface of the printing forme is sucked off.
