Abstract
A plastic material which is suitable for simulating engraving on metal has a substrate which is not deformed by the heat or pressure of a hot stamping process. A sheet or layer of thermoplastic material of limited thickness is laminated to the upper surface of the substrate. The opposite side of the thermoplastic material is covered by a containment film. Thus, within the limits of manufacturing tolerances, the layer of thermoplastic material may be subjected to any amount of pressure to produce a debossment which is no deeper than the depth of the limited thickness when a hot stamping die bottoms on the non-deformable substrate. Therefore, there is a much more predictable end product.
