ABSTRACT:
A frame structure for supporting a stretched printing screen of the kind used in the so-called silkscreen printing process. The frame structure is intended for use in screen printing relatively large surface areas, and comprises frame members which are joined at their ends to form an open rectangular screen frame across one side of which the printing screen is stretched. At least two opposing frame members of the screen frame have a unique truss construction which resists either or both vertical bending or sagging of the frame when it is raised and lowered during a screen printing operation and inward bowing of the opposing frame members in the plane of the frame by tension in the stretched printing screen.
