Abstract
Described herein are an apparatus and a method for direct engraving an elastomeric printing plate or sleeve by multiple laser beams simultaneously. In one embodiment, an elastomeric printing plate or sleeve is positioned on an imaging drum for direct engraving. The imaging drum is rotatable around its longitudinal axis. Such rotation defines a circumferential direction, also called the transverse direction. The axis of rotation defines an axial direction, also called the longitudinal direction. The printing plate or sleeve has an body and a surface made of an elastomer (made of polymer or rubber). A drive mechanism provides relative motion between a plurality of laser beams and the plate or sleeve in both the transverse and longitudinal directions.
