    摘要: A method for marking and authenticating a security article, such as a banknote, a document, a ticket, a foil, a thread, a label, a card, or a commercial good, so as to provide for an easy authentication of said article by a machine, such as a currency acceptor, a ticket validator, or a hand-held authentication device. The security article is marked with a user-defined design, wherein said marking comprises dyes or pigments belonging to an extended, or hyperchromic color space which is not reproducible by commercially available, 4-color desktop reproduction equipment. The marking is authenticated by mathematically transforming crude spectral information to statistically independent hyper-color coordinates, and comparing selected hyper-color coordinates with corresponding reference values.

    摘要: The invention discloses a security element for a banknote, a document of value, right or identity, a ticket, a label, a branded good identifier, or a tax banderole. The element comprises a combination of a coating containing at least one optically variable pigment having a substantial viewing-angle dependent color variation, with at least one selective spectral absorbing material, which blocks out visible spectral components reflected by the optically variable pigment at orthogonal incidence. The security element appears black when viewed at orthogonal angle, and colored when viewed at grazing angle.
