Abstract: A screen printing apparatus is provided with an improved registration system to ensure that a printing screen frame descends to a specific, predetermined, precise position relative to a screen printing platen each time it is lowered. The screen frame and the platen are provided with pairs of laterally separated registration elements. The platen may be provided with a pair of laterally separated, registration pins that project upwardly to corresponding registration openings defined in an angle bar that is attached to the distal end of the screen printing frame. Each time the screen printing frame is lowered down into a horizontal disposition directly above the platen, the registration pins enter the openings and ensure accurate, precise, consistent registration of the screen relative to the platen. In a multicolor screen printing machine a plurality of screens are carried by mounting arms that are hinged about horizontal axes to a turntable. Each platen is provided with an identical pair of registration pins at its distal extremity remote from the turntable axis. Each printing screen frame is likewise provided with an identical spaced pair of registration openings. The angle bar in which the openings are defined can be attached to the distal ends of the side rollers in a retensionable frame, as well as across the distal end of an older style, nonadjustable screen printing frame.
