A printing press comprising a plate cylinder having an outer circumferential surface having an axially-extending slot therein, the slot having a first side and a second side, the plate cylinder having an axially-extending hole at least partially opening along the first side and having a hole axis. A printing plate has a lead edge and a tail edge, the lead edge and tail edge being located in the slot, and the plate cylinder has an eccentric shaft situated in the hole. The eccentric shaft is for eccentric rotation with respect to the hole axis so as to selectively provide a force against the lead edge and tail edge.
