发明名称 Method for screen printing
摘要 The specification discloses a method for screen printing comprising providing a sheet of masking sized to cover a porous printing screen, with pressure sensitive adhesive on one side of the masking and a protective cover sheet thereover. The masking is positioned, cover side up on a work surface, and the desired pattern is scribed on the cover sheet with a pointed instrument, so as to form an indentation in the masking which is visible from the front side thereof. The masking is then turned over on the work surface, front side up, and is cut along the indentation. The cover sheet is peeled from the back side of the masking, thereby removing the enclosed, cut areas from the masking to form a mask or stencil corresponding to the desired pattern. The stencil is then pressed onto the lower side of the printing screen to attach the same to the screen.
