Abstract
347,657. Printing surfaces. HERBERT PHOTOS, Inc., 480, Lexington Avenue, New York, U.S.A. Oct. 24, 1929, No. 32343. Convention date, April 19. Void [Published under Sect. 91 of the Acts]. [Class 100 (ii).] Consists in a method of producing flexible printing-plates bearing pictures, advertisements, &c., in half-tone and descriptive matter or headings in clear lines. From a photograph of the picture &c. is prepared a copper or zinc plate 11, Figs. 1 and 5, bearing a copy of the picture in half-tone. Outside the area of the picture and on a smooth background is formed the clear line headings or descriptive type matter 11a and the plate is also preferably formed with ridges and depressions 11c, 11b, Fig. 5. A number of lead moulds 12, Fig. 5, are obtained from the plate 11 by pressure, the ridges and depressions 11c, 11b preventing side flow of the lead. The moulds 12 are then placed in one or more recesses 14b, Fig. 4, in a frame comprising a base 14 and a frame or bars 15 which overlie the edges of the moulds. A sheet 16 of celluloid, fiberloid (produced from paper, camphor, and alcohol), or other suitable material to form the printing plate, is then pressed upon the mould by means of a felt or other resilient member 17 in a hydraulic or other press. The member 17 is smaller than the opening in the frame 15 so that side flanges 16a are formed on the plate to facilitate attachment to the mounting block.
