  • Publication number: 20240002989
    Abstract: A method for producing a pressing tool for producing a workpiece, the pressing tool may include a pressing surface having a structure of protrusions and recesses, the method may include applying a mask for covering regions, applying a metal layer to the regions not covered by the mask while adding mineral particles, and/or repeating the foregoing steps until the pressing surface with the structure of the protrusions and recesses is formed by repeated, layered application of masks and metal layers while adding mineral particles. The pressing surface may have regions of different degrees of gloss and/or metal of at least two metal layers may be different in order to obtain the regions of different degrees of gloss.
