A pressing tool for producing a workpiece, comprising:
- a pressing surface,
- a base structure, which comprises a surface, and
- at least two ceramic layers which are arranged on top of one another on the surface and form the pressing surface, of which one of the ceramic layers is a full-surface ceramic layer with one degree of gloss and the other is a partial ceramic layer with a further degree of gloss which differs from the degree of gloss of the full-surface ceramic layer.
A method for producing a pressing tool, comprising the following method steps:
- providing a base structure, having a surface,
- applying a first ceramic layer onto the surface of the base structure, and
- applying a second ceramic layer onto the first ceramic layer, wherein one of the first and second ceramic layers is a full-surface ceramic layer and the other of the first and second ceramic layers is a partial ceramic layer, and wherein the degrees of gloss of the first and second ceramic layers differ.
