Cassette for storing and accessing plates within an automated plate handler

摘要

A light-tight cassette for housing a stack of unexposed printing plates in an automated plate handler, includes a bottom container and a removal cover fitting onto the bottom container to enclose an interior of the bottom container and make the interior of the bottom container light-tight. A first registration member is provided inside the bottom container for a first side of the stack of plates to be referenced against. A second registration member is provided inside the bottom container for a second side of the stack of plates perpendicular to the first side to be referenced against. A first adjustable stop member is positioned opposed to said first registration member for securing the stack of plates with the first side referenced against the first registration member. A second adjustable stop member is positioned opposed to said second registration member for securing the stack of plates with the second side referenced against the second registration member.
