ABSTRACT OF THE DISCLOSURE The specification describes a register system for the inregister aligning of a flexible printing plate on the plate cylinder of a rotary printing press. The system includes at least two register punch holes provided in the printing plate and corresponding register marks in the plate cylinder. The register marks have an area similar to and smaller than the register punch holes, the register marks lying at most on a level with the surface of the printing plate and contrasting with their surroundings. The disclosed system is easy to operate and guarantees the accuracy of the printing plate is retained when it is used on the press. Furthermore, the system overcomes problems of prior art arrangements by providing precise alignment quickly and without damaging or deforming the register punch holes.
