Wet-Gate Printing on a Continuous Contact Printer
A system for wet-gate printing with a Bell & Howell Model J Printer has been designed to render scratches, digs and abrasion marks nonprintable, whether the defects occur on the base or emulsion of the negative. Both sides of the negative and the emulsion side of the raw stock are coated, and special modifications of the film paths of the two films are made in order to produce optimum contact. Very accurate control of the quantity of liquid applied to each film surface was found to be essential; this was achieved by means of a carburetor acting as a pressure regulator, and a wick used to control flow.
