Method for mounting printing plate on printing press

摘要

Disclosed is a method for mounting a printing plate having a paper or synthetic resin film as a support on an offset rotary printing press by inserting both ends of the printing plate into a holding slit of printing cylinder and a slit of a gripping rod which comprises previously folding the printing plate at the positions in both end parts of the printing plate which correspond to the positions of the holding slit of the printing cylinder and the slit of the gripping rod, respectively, to form hooked portions to be inserted into the slits, inserting one end portion of the printing plate into the holding slit of the printing cylinder and another hooked portion of the printing plate into the slit of the gripping rod and fixing the printing plate on the printing cylinder by stretching the printing plate by rotating the gripping rod, wherein perforations are previously made along which the printing plate is folded and the printing plate is folded along the perforations when the printing plate is mounted on the rotary printing press and/or said gripping rod is subjected to surface-working in at least in the portion which contacts with the printing plate to provide this portion with frictional force.
