Abstract
A method of further inserting a partially inserted leading and/or trailing edge of a printing plate into respective lock-up slots in a plate cylinder of a printing press to allow register slots in said edges to engage with lateral pins or a register mechanism in said lock-up slots is disclosed. The method comprises the step of positioning a pushing element relative to the curved surface of the plate cylinder, on which a printing plate is disposed with its leading and/or trailing edges partially inserted into their respective lock-up slots, such that said pushing element will engage and push a raised portion of said printing plate, adjacent to said partially inserted leading and/or trailing edge, down onto the surface of the plate cylinder and the leading and/or trailing edge further into their respective lock-up slots, as said plate cylinder rotates.
