Abstract

442,473. Photo-mechanical printing- surfaces. HEIDENHAIN, J., 108, Gitschinerstrasse, Berlin. March 14, 1935, No. 7951. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 16, 1935.] [Class 98 (ii)] Originals for producing photo .mechanical printing plates without the use of screens are prepared by applying a layer of heavy metal sulphide e.g. lead sulphide to a grained transparent support e.g. a glass, celluloid or other transparent plate, applying a drawing to this by means of a material which is unattached by a solvent for the sulphide layer, and dissolving out the unprotected parts of the layer. The drawing may be applied by means of grease chalks or by applying a light sensitive layer e.g. of asphalt, exposing under the drawing and removing the unaffected parts, for example, with turpentine. The process of Specification 183,817, [Class 98 (ii)], may also be used. Specification 327,068, [Class 98 (ii)], also is referred to.
