    Abstract: The present invention relates to a method and a system for the local or remote authentication of an item, in particular a security document, with the help of a authenticating device, comprised in, connected to, or linked to mobile communication equipment. Said item carries a marking exhibiting a characteristic physical behavior in response to interrogating energy, such as electromagnetic radiation and/or electric or magnetic fields. Said marking may comprise physical and logical security elements, e.g. a barcode, or a characteristic particle or flake pattern, exhibiting a characteristic physical response.

    Abstract: A bleeding or fugitive printing ink is disclosed and claimed which can be printed by the method of dry or wet offset or letterpress. This ink allows, when printed on security documents and dried, to prevent attempts of forgery or counterfeit in that the ink contains at least one dyestuff which is sensitive to organic solvents and other chemical reagents. The ink, when printed, forms a solid, polymerized or cross-linked binder matrix on the surface of the document when the printings are submitted to energy radiation, or by an oxypolymerization reaction. This matrix is formed near immediately, in the case of oxypolymerization within 24 hours, in contrast to conventional bleeding printing inks whose matrixes do not really dry and remain liquid in the interstices of the substrate.

    Abstract: A printing ink for the printing of security documents by the method of engraved steel die printing, wherein the volatile solvents comprise at most 15%, referred to the total weight of the ink, of one or more volatile organic substances, and wherein the volatile matter may further contain water.These inks reply to the new environmental requirements and have still a better wipability on the printing cylinders or plates. They allow document printing without interleaving.

    Abstract: A printing ink for the printing of security documents by the method of engraved steel die printing, having a viscosity of at least 1 Pa.multidot.s at 40.degree. C. under a shear of about 1000 sec.sup.-1, containing a binder matrix, a polymerization initiator for polymerizable matrix components, fillers and pigments, and the usual additives. The binder matrix contains at least one cationically polymerizable compound, modified to bring about the desired rheology of the ink, and the photoinitiator, activable by UV, heat and EB, is an onium salt capable of releasing a Lewis or Bronsted acid.This ink has best and very rapid drying characteristics.

    Abstract: The invention relates to an ink set comprising a plurality of inks of a first and of a second group, having different colors. Inks of said first group comprise a visible colorant and an additional IR-absorbing compound (IR-taggant) which has an absorption peak at a predetermined wavelength in the near infrared. Inks of said second group comprise a visible colorant which has at the same time an infrared absorption peak at the same wavelength as that of the IR-taggant used in the inks of the first group. Preferred embodiment is a four-color process ink set comprising an IR feature.
