ABSTRACT:
A relatively light weight screen printing frame structure particularly adapted for use in making relatively large area screen prints. The frame structure has an open rectangular screen frame proper including truss frame members along at least two opposing sides of the frame which mount screen gripping and tensioning means and have a unique open truss construction which resists bending of these frame members by the screen tension forces and other forces acting on these members during screen printing operations. In the preferred screen frame structure described, the reinforcing truss structures of the truss frame members are located inwardly of the screen gripping and tensioning means in such a way as to minimize the overall size and weight of a frame structure for supporting a printing screen of any given useful area.
