Process for manufacturing a pressing die, especially for the production of optical discs. According to the invention, this process is characterised in that it consists in mounting a master disc (1), pre-etched by any known method, inside a support (8) in such a way that the surface of the disc coincides with that of the support, the die subsequently being produced by galvanoplastic replication of a blank (12), achieved directly on the etched surface of the master disc. <IMAGE>
