embosser

This term refers to both the mechanical tool and the artisan performing the craft. When referring to the device, it often implies a professional or legal context, such as the handheld stamps used by notaries to create a permanent, tactile seal that is harder to forge than ink.

In the context of a person, the word describes a specialist in leatherwork, bookbinding, or metalwork. The focus is on the physical manipulation of a material to create a three-dimensional effect, distinguishing it from printing or engraving which removes material or adds ink.
