Abstract
An apparatus and method for positioning and aligning one or more pre-punched printing plates on a cylinder for imaging a plate in a computer-to-plate drum imaging device. The apparatus includes an imaging cylinder and a registration device connectable to the cylinder. The apparatus includes at least one groove and one pair of register pins, with a first register pin in a fixed position, and a second register pin movable in the groove to a second position, and collinear with the first register pin in the axial direction of the cylinder, arranged such that when connected to the cylinder, the registration device allows a plurality of pre-punched printing plates with variable widths to be positioned and aligned on the cylinder with simplicity.
