Abstract

Major developments in the evolution of embossed holography are discussed in this paper. It contains brief descriptions of typical systems and techniques, as well as problems that were encountered. It is unavoidably narrow in that it represents the perspective on the author, dealing mainly with Eidetic Images. ABN Holographics, and Simian Company. All of the major processes currently used in embossed holography had been demonstrated by 1970. Yet it took another decade for embossed holography to flourish since no market materialized in spite of efforts to invent one. Then in 1981, American Bank Note purchased the rights to the Leith/Upatnieks patents, and acquired Eidetic Images, a holographics origination laboratory, as well as an embossing plant called `Old Dominion Foils'. The mating of these two acquisitions allowed product to be made almost immediately. Later developments included a hot stamp foil required for credit card holograms, a production casting system for National Geographics magazine covers, a composite (stereogram) system, and computer generated imagery. Current technology has obsoleted many of the old methods, mainly because of advances made possible by the extensive use of computers both to create the imagery and to control the hologram construction.
