Embossing processes enable fine structures to be transferred to the surface of a workpiece. Coin minting is one of the best-known processes. In addition, holographic security features on identity documents are also produced by means of an embossing process. For this purpose, the electroformed negatives of the holographic structures are embossed into the surface of plastic foils, which are then applied to the target product by adhesive bonding. A variety of new applications are also offered by holograms that are embossed directly into the surface of sheet materials, thus forming an inseparable bond with the product. These embossed markings protect the product against imitation on the one hand and ensure an exclusive product design on the other. The feasibility of embossing holograms directly into metallic materials has been demonstrated in several research projects at IFUM.

The precise embossing of diffractive structures in polymers is currently being researched as part of the PhoenixD cluster of excellence.
