ABSTRACT:
A registration/adapter apparatus for aligning a priming screen with an image platform. A screen tensioning and printing frame has four tensioning rollers coupled together by comer members. The comer members support the rollers for rotation about their longitudinal axis. Each roller has a channel for retaining an edge of a screen fabric. A means of locking each roller in a predetermined rotative position to hold the screen fabric at the desired tension is associated with each corner member. One of the rollers and its associated corner members has a pair of alignment means. The alignment means have a hole associated with one corner member and a slot associated with the other corner member. A registration member associated with the image platform has a pair of pins for aligning and being received by the hole and slot in the alignment means associated with the screen tensioning and printing frame. The pins received by the hole and slot ensure alignment of the screen tensioning printing frame with the image platform.
