Abstract
A registration system for exposing photosensitive sheets to controlled light through images formed on film includes a thin, relatively stiff, dimensionally stable support board having a relatively flat upper surface for supporting a photosensitive sheet and an image forming film sheet in overlying relation thereon including an upper layer formed of resilient material and having at least one registration opening extending between opposite faces of the board for receiving a registration pin. The pin includes a stop flange adjacent a lower end for limiting upward movement of the pin in the board and includes an upper body normally projecting above the upper surface of the support board to extend into aligned registration openings which are punched in the photosensitive sheet and the image forming film. Each opening has a diameter in the upper layer of the board that is slightly less than the diameter of the pin and the resilient material around the opening holds the pin in the board even after extended use and wear causes the pin to fit loosely in a lower layer of the registration opening.
