Abstract: A screen printing frame comprises four extruded plastic frame members made of a material which is recyclable and resistant to attack by the inks and solvents used in a sreen printing process. Each of the frame members include transverse reinforcing webs dividing the frame member into four elongated channels. At each mitered junction of the frame, four L-shaped plastic connectors are inserted into the contiguous channnels of contiguous frame members and adhesively secured. The screen or mesh is suitably stretched and attached to the frame by means of an adhesive.
