Abstract
An electrosensitive substrate from which a metallized surface layer is selectively removed using electrosensitive printing to expose a patterned underlayer. The patterned underlayer may be randomly exposed, or exposed in prescribed portions. Tags, labels or the like of this description may be electrically imprinted with unique identification codes, such as serially printed alphanumeric characters. Such tags and labels resist duplication by conventional printing techniques. The patterned underlayer may be imprinted using inks of a variety of surface textures, resulting in an embossed effect in the metallized surface. Alternatively, a lacquer layer may be provided between the patterned layer and the metallized surface to achieve a uniform appearance of the metallized surface.
