Abstract
A screen printing apparatus comprising a screen having an opening or openings of a desired print pattern and having a lower surface being positioned adjacent to a substrate to be printed, and a nonflexible squeegee comprising a cavity for containing a material to be printed on the substrate. The cavity is defined by the interior surfaces of surrounding walls extending generally vertically from the lower extremities at which the squeegee directly contacts the upper surface of the screen. While the squeegee travels with respect to the screen the material to be printed flows from the cavity into the openings of the screen, and thereby onto the substrate. The squeegee may be formed of stainless steel, a ceramic material or a synthetic resin.
