Thin-film devices in security printing inks, 1210
Papers and any printable surface that have value are subject to forgeries. Various methods of security printing are identified and utilizing luminescent pigments as security items are discussed. Problems with classical luminescent pigments because of toxicity and particle size are identified. A new range of luminescent pigments that are either excited by UV or IR are presented and their chemical and physical characteristics defined. Also samples from actual security applications are given. © 1995 John Wiley & Sons. Inc.
