Abstract
A device and method prevents movement of a printing plate during clamping of an end of the plate to an external drum of an imaging system using a clamping apparatus having: a clamping portion disposed on the external drum, wherein the clamping portion may be selectively displaced between a clamping position for clamping the leading edge of the printing plate against the external drum and a release position; and an inflatable member positioned between the clamping portion and the external drum for displacing the clamping portion between the clamping position and the release position. The device includes: a first spring-metal component mounted onto the external drum wherein the end of the plate can be positioned between one end of the first spring-metal component and the external drum, and the first spring-metal component is positioned between the clamping portion and the plate, to prevent the plate from moving during clamping.
