Abstract
Printing plates can be reliably extracted from a plate cylinder with an automatic plate changer even when the plate lock has a very narrow plate gap between the trailing edge and the leading edge of the printing plate. First, the trailing edge of a printing plate is released by the locking member and the printing plate is elastically deformed at the trailing edge. This allows the guide fork of the automatic plate changer to reliably peel the printing plate away from the plate cylinder. In addition, the guide fork may engage the leading edge of the printing plate after the plate lock has been disengaged once more and peel the leading edge away from the plate cylinder by pivoting away from the cylinder.
