A process for producing a metal mould (1) provided with at least one structured surface (2) bearing a pattern (3) obtained by applying, to the surface (10) of an initial mould (4), a first protective layer (5) that reproduces said pattern (3) and subsequently treating the surface thus prepared with a corrosive substance suitable to create corroded portions (6), distinct from the uncorroded portions (7) coinciding with said protective layer (5). The invention also provides for applying, to the aforesaid surface (10) of the mould (4) a second protective layer (8) and subsequently treating the surface (10) thus obtained with a matting substance, suitable to form a structured surface (2) having corroded portions (6) with a degree of gloss different from that of the uncorroded portions (7). In relation to the prior art, the process of the invention can be used to obtain a metal mould provided with at least one structured surface in which, as no additional materials are used with respect to those forming the actual mould, the production costs are lower and the method as a whole is also simpler, faster and more effective. In this way, the mould with structured surface of the invention is reliable and durable, also because the absence of coatings on the structured surface of the invention prevents adhesion of the panel to the surface of the mould. |
