Abstract

271,468. Depth-o-Tone Corporation, (Assignees of Stockinger, F.). May 18, 1926, [Convention date]. Drawings to Specification. Photo-mechanical printing-surfaces.-In a process of producing printing plates for photo-encess of producing printing plates for photo-engraver's cuts, an impression is made from an inked, etched, half-tone copper plate on to a crystal glass plate and this impression is utilized as a diapositive to make an intaglio zinc printing plate, from which impressions are made on to the offset blanket. In making the zinc plate it is coated with ink-shedding varnish after etching, the varnish being removed from the surface, but left in the hollows.
