SETT ATT MERKA UT PASSMERKEN

摘要

A method for forming or marking register marks used for the automatic registration between a plurality of printing plates in a printing press. A register mark forming or marking device is mounted on a printing frame of an automatic composer so that a register mark can be formed or marked on a printing plate simultaneously with the printing of a film original over the printing plate. Misalignment between the thus formed or marked register marks and patterns or images can be eliminated.
