Abstract
Embossed holograms or diffraction patterns are formed on hard, unembossible metal substrates such as steel sheet metal. The hard metal substrate has a soft embossible metal layer such as tin formed on it, and holograms are embossed thereon by means of a surface relief, metal master. The soft metal layer must be sufficiently thick to accommodate the deepest surface relief pattern. For tinplate, the embossing can be preformed at room temperature. Among other things, the process produces tinplates and tin cans with embossed holograms.
