The apparatus and method of the present invention uses a register light unit to facilitate manual alignment of master photographic images on a flexible carrier sheet. The carrier sheet and master images are positioned relative to a photosensitive screen using a vacuum contact plate that receives a screen frame in tight registration using a substantially planar surface for supporting the flexible carrier sheet with master images thereon. Vacuum is drawn around the screen to develop a pressure differential across the carrier sheet to urge the master images thereon into surface contact with the photosensitive screen during exposure to a source of illumination. Work stations include storage bins for prepared screens and master films to expedite processing through an exposure unit that includes a vacuum contact plate which is mounted to translate between a load/unload position outside of a housing and an exposure position inside of a housing that shields an operator from radiation from the source of illumination.
