Tiefprägeprägung

Tiefprägeprägung, a German term, translates to "deep stamping" or "intaglio printing" in English, particularly in the context of coinage and medals. It refers to a method of creating raised designs on a metallic surface by impressing a die, which bears the desired image in reverse and in sunken relief, onto the blank metal. The die itself is a hardened steel tool, meticulously engraved with the artwork.

The process involves placing a blank piece of metal, often a coin or medal, onto a hardened anvil or base. The die, containing the negative image, is then positioned above it. Tremendous pressure is applied, either hydraulically or through mechanical means, forcing the metal to flow into the recessed areas of the die. This action pushes the metal outwards, creating the raised design on the coin or medal. The depth of the impression and the intricacy of the design are determined by the precision of the die engraving and the force of the stamping.

This technique allows for the production of highly detailed and durable images. Historically, Tiefprägeprägung has been a fundamental method for minting coins and producing commemorative medals, ensuring both aesthetic quality and longevity of the imprinted designs. Modern applications may involve advanced machinery, but the core principle of impressing a sunken design into metal remains consistent.
