Abstract: A method and apparatus for screen printing a sequence of accurately registered images on a plurality of sheets or objects such as T-shirts use a primary register platen supported by a platen support table. The primary register platen may be moved in a horizontal plane relative to the platen support table, and repositionably secured thereto. Each object to be printed is temporarily fastened to separate secondary register platen, which may be quickly placed in a precisely repeatable overlying relationship to the primary register platen, and quickly removed therefrom. The apparatus includes a transparent register plate which may be quickly placed in an overlaying relationship to an object on a secondary register platen, in a precisely repeatable position relative to said platen support table, and quickly removed therefrom.

Abstract: A vacuum exposure registry apparatus holds a thin, image-bearing sheet in intimate contact with a flat photo-sensitive surface while exposing both to a light source to register an image on the photo-sensitive surface. The apparatus includes a flat plate made of rigid transparent material and having a hollow, tubular vacuum fitting extending through the plate near a corner of the plate. A flexible elastomeric tube joinable at its ends to form a continuous perimetral loop is placed around an image-bearing sheet lying on a photo-sensitive surface. The plate is then placed down on the upper surface of the elasomeric tube, with the lower opening of the vacuum fitting within the perimetral boundary defined by the loop. Applying a vacuum to the vacuum fitting evacuates the region within the loop and between the plate and photo-sensitive surface, drawing the surface and overlying image-bearing sheet into tight contact with the underside of the plate.
