Abstract

276,070. Trist, A. R. May 18, 1926. Printing-surfaces.-In a printing-plate having mercurial ink-repelling areas and comprising upper and lower layers of metal supported by a metal base, the metal employed for the upper layer is unaffected by mercury and is soluble in an etching-fluid, whilst the metal employed for the lower layer is practically insoluble, in the etching-fluid and will amalgamate with mercury. Preferably iron or mild steel is employed for the base, and the upper and lower layers consist of chromium and copper or copper alloy respectively. In the manufacture of the plate, the iron base is immersed for two or three minutes as an anode in a 10 per cent solution of sulphuric acid and. is supplied with a current of high density, for instance 200 amperes per square foot. The base is then electrolytically coated with successive thin layers of nickel, copper, and chromium, the nickel layer causing the copper layer to adhere to the base. The layers of copper and chromium may be from three to ten thousandths, and from one to two ten-thousandths of an inch in thickness respectively. In the subsequent preparation of the plate a resist is applied locally to the chromium layer and an etching-fluid is employed to dissolve the exposed parts a suitable etching- fluid consisting of one volume of concentrated hydrochloric acid solution, and three volumes of glycerine. Gold or silver is then deposited on the exposed parts of the copper layer by treating the plate with a solution of cyanide of gold or silver. If the deposit does not fill the recesses in the chromium layer, the plate is employed as a cathode in the solution and current is passed until the deposit is flush with the surface. After washing and drying, the plate is polished with mercury and chalk, the mercury amalgamating with the gold or silver parts to form ink-repelling. areas.
