Abstract
Abstract The material to be applied by a screen printing technique is mixed with a thermoplastic vehicle which is solid at room temperature and melts at a predetermined elevated temperature. The material is formed into a slab which is then pressed against a screen surface. The screen is heated enough to melt a portion of the slab and the molten material is then forced through the screen by a squeegee.
