Abstract

Improvements introduced into systems of reproduction of original engravings. The improvements consist in replacing the classical working phases of engraving Cobex sheets by means of stamping, that is to say, depositing said sheets on the original plate and pressing and heating it and, in addition, the following metallisation phase of said Cobex sheets in a copper galvanic bath, by two phases being the application of resins or polyurethanes with polymerisation, specifically a first phase in which the polyurethane resin is poured over the plate or original engraving, forming a layer of suitable thickness, which self-polymerises in a period of approximately one hour, obtaining an engraving with the design referred to, and then over the resin or polyurethane part thus obtained, a second layer is deposited or poured, of another resin or polyurethane, by means of which a negative plate is obtained, from which, as is conventional, by means of nickel electrolytic baths, a first positive nickel mould and a second nickel mould engraved in negative is obtained.
