Abstract

322,007. Weck, H., Weck, T., and Buggenhoudt, G. van. Sept. 3, 1928. Photo-mechanical printing-surfaces.-Printing plates are prepared by superposing a layer of casein-gelatin on a layer of chrome-gelatin and exposing the sensitized surface through a screened negative. The plate e.g. of zinc, is coated with a layer containing gelatin, chromealum, potassium silicate and water. Over this is applied a layer consisting of casein, hard gelatin and water. The plate is sensitized with ammonium bichromate and exposed for 2 to 4 minutes to arc lamps of 4000 candle power. The plate is then washed, first with water and then with glycerine. For printing it is moistened with glycerine and water, leather rollers being used for inking and hard gelatin rollers for drying. It is claimed that a screen negative with the white areas free from black dots and the black areas free from white dots may be used.
