ABSTRACT:
A registration/adapter apparatus aligning a printing screen with an image platform. A screen tensioning and printing frame has four tensioning rollers coupled together by corner members. The corner members support the rollers for rotation about their longitudinal axis. Each roller has a channel for retaining an edge of a screen fabric. A bolt associated with each corner member locks each roller in a predetermined rotative position to hold the screen fabric at the desired tension. One of the rollers has a pair of associated adapters interposed between the head of the bolt and the associated corner member. The adapter has a hole on one surface and a slot on the opposite surface. 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 adapter 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.
