Abstract (en)
[origin: DE3930584A1] The novel electro-photographically produced offset printing plate comprises an electrically conductive dimensionally stable substrate (A), at least one photoconductive layer (B) and a printing surface (C) composed of hydrophilic, water-bearing, unprinted tonered areas (c1) and oleophilic, colour-bearing printing untonered areas (c2). The novel offset printing plate can be made by the prior art manner making use of hydrophilic toner or toner which can be easily hydrophilised chemically by conversion with suitable reagents, thermo-chemically by heating and/or photo or radio-chemically by irradiation with electromagnetic or particle radiation.
