  • Patent number: 7892338
    Abstract: The invention discloses 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. According to the disclosed method, the security article carries a marking in the form of 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 authentication of said marking includes the mathematical transformation of the crude spectral information to statistically independent hyper-color coordinates, and the comparison of selected hyper-color coordinates with corresponding reference values.

  • Patent number: 7402614
    Abstract: Re-dispersible pigmented printing ink compositions, preferably for the continuous ink jet printing process are obtained by the addition of a flocculating agent to the pigment dispersion in the printing liquid. The compositions do not form hard sediments and are easy to re-disperse on stopping and resuming the printing operations. Suitable flocculating agents bind the pigment particles in the sediment into three-dimensional “airy” structures, which are easy to break up. The ink compositions of the invention are furthermore characterized by a good printability in the dispersed state.
