ABSTRACT:
Process for the production of flexographic printing plates by means of direct laser engraving, in which the particulate and gaseous degradation products formed in the course of the engraving are taken up by means of a suction apparatus, and the waste gas stream laden with the degradation products is purified by means of a combination of at least one solids filter and at least one oxidatively operating purification stage.
