  • Apparatus and method for screen printing a rigid object with cleaning of the print side of the frame
    Patent number: 5485781
    Abstract: The apparatus for screen printing from one edge to the other of an object of a rigid material, beside the conventional components for screen printing, includes a scraper, acting on the lower face of the printing frame, for removing ink from the portion of design that exceeds the perimetric dimensions of the object to be printed. Through the apparatus it is possible to perform a method for screen printing from one edge to the other of an object made of a rigid material, which method consists of printing the design on the object, exceeding the printing on at least one of the edges of the object; spacing the printing frame from the printed object and scraping, from the lower face of the printing frame facing the object, ink which has not been deposited on the object because of the lesser dimensions of the object with respect of the design.
