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. A screen frame pivotable in vertical plane and fastened to the platen support table is pivoted down into overlying contact with the upper surface of the transparent register plate, and a test image printed on the surface. The screen frame is then tilted away, permitting repositioning and securing the primary register platen to align the image with a desired printing position on the surface of the object affixed to a secondary register platen attached to the primary support platen. The transparent register plate is then removed, permitting the surface of the object to be printed. Since each secondary platen bearing an object is removably installable on the apparatus in a precisely repeatable position, each object may be printed with a precisely registered image.
