Abstract
Abstract The invention disclosed is directed to a mounting means for detachably mounting flexible thin printing plates. Printing plates are detachably mounted on at least one terminal edge of the backing plate or saddle by means of a studded plate securing bar which is spring biased by a slidable bar positioning element. The co-action of the positioning element and the securing bar both disposed within the thickners of the backing plate or saddle provides an efficient highly acceptable means for securing a thin printing plate in position.
