  • Publication number: 20150132543
    Abstract: This invention relates to the field of authentication of coating compositions such as varnishes, inks and paints, and it is particularly useful in the field of authentication of such coating compositions when applied to substrates like banknotes or other valuable documents. It is particularly directed to a marked coating composition. e.g. an ink, that is marked with a marker (taggant) such as to allow for its authentication, and a method for authenticating such a marked coating composition. The marking is achieved by covalently binding a taggant to a coating composition component. e.g. such used for security documents. The taggant, which is not extractable through usual chemical treatments like washing methods or the use of solvents, can be detected and identified upon thermally induced chemical fragmentation with a PY-GC-MS apparatus. The marked ink or the marked substrate is thus authenticated as belonging to a particularly marked ink, varnish or batch.

  • Publication number: 20150104800
    Abstract: A method for authenticating a textile material that is initiated by selecting a unique nucleic acid marker having a specific length and a specific sequence. A media that causes the unique nucleic acid marker to adhere to a fibrous material is then selected. The method then proceeds to generate a nucleic acid marker mixture by mixing the media with the nucleic acid marker. The nucleic acid marker mixture is then applied to the fibrous material. A marked fibrous material is produced by marking the fibrous material with the nucleic acid marker. The textile material is manufactured with the marked fibrous material. The textile material is then authenticated by detecting the unique nucleic acid marker with primers that are specific to the unique nucleic acid. In an alternative embodiment, the media is used as a topical treatment for the fibrous material.

  • Publication number: 20140106357
    Abstract: A method of marking an inventory item includes providing an activatable smoke generator and a reservoir for holding a smoke fluid and adapted to provide a flow of smoke fluid to the generator. The reservoir contains a smoke fluid including a carrier nucleic acid having a uniquely identifiable sequence, and upon activation of the smoke generator, marker smoke is generated and targeted to flow over the inventory item. The method further includes activating the smoke generator to produce the marker smoke including the carrier nucleic acid so as to cause the marker smoke to flow over the inventory item and thereby to detectably mark the inventory item with carrier nucleic acid.

  • Patent number: 8697177
    Abstract: There is described a method for varnishing security documents, especially intaglio-printed security documents such as banknotes, wherein both sides of the security documents are covered by a protective varnish. The method comprises the step of applying a thicker layer of protective varnish on a side of the security documents which exhibits a greater surface roughness, especially the side which is opposite to the side of the security documents which was last printed by intaglio printing. Also described in a varnishing machine for carrying out the above method.

  • Patent number: 8691369
    Abstract: A layer combination with a marking is proposed, for example, for a miniaturized electrical component. The layer combination includes a first layer and a different release layer, which is applied on it, on which a pattern is formed by a released pattern-like area. The release area is formed from an inorganic, semiconducting, insulating material, where the pattern produced thereon is machine-readable.

  • Patent number: 8685488
    Abstract: The present invention relates to a method for producing a micropattern on a substrate (22), in which a substrate (22) is provided with a relief pattern (26, 28) that exhibits elevations (26) and depressions (28), and in which the elevations (26) and/or depressions (26) are arranged in the form of the desired micropattern, and with a printing tool, an imprint material (30; 34) is transferred to the relief pattern (26, 28), the viscosity of the imprint material (30; 34) being chosen such that the imprint material (30; 34) is selectively transferred either substantially only onto the elevations (26) or substantially only into the depressions (28) of the relief pattern.

  • Publication number: 20140077485
    Abstract: An article includes a substrate and a graphical component forming an image and an optical component which includes magnetic pigment flakes aligned so as to form a frame pattern which surrounds the image. When light is incident upon the pigment flakes from a light source, light reflected from the frame pattern forms a dynamic frame which surrounds the image and appears to move as the substrate is tilted with respect to the light source. The image appears to be stationary when the dynamic frame appears to move.

  • Patent number: 8632849
    Abstract: An anti-counterfeit film comprising an amphichroic pattern is prepared by (1) mixing a polymerizable liquid crystal material of chiral structure and a photoinitiator, blade-coating the mixture on a base film and then drying; (2) partially exposing the resulting material produced in step (1) using a positioned UV lamp, then drying and exposing in an UV radiation to obtain a desired film. The film prepared by the method has an amphichroic pattern which typically presents a red and green picture when being vertically observed, the original red and green respectively changes into green and blue when being observed at a certain incline angel. The anti-counterfeit film is characterized by obvious color change, easy identification, practicability and convenience, thus facilitating promotion and application.

  • Publication number: 20130266722
    Abstract: A security device includes an optically variable device (OVD) having diffraction-based micro-optics including at least one moiré magnified visual representation of a micro-object. A diffractive structure provides micro-objects with unique optical effects when the OVD is viewed through the micro-object structure from a predetermined relative observation point. In addition to magnifying the micro-objects, the diffractive structure can impart optical effects such as change in observed color, enhanced contrast, animation of the observed visual representation, and change in size or shape of the observed visual representation. The micro-objects and the diffractive structure can be disposed on the same or different portions of a substrate. A method of making OVDs, and an article employing such OVDs are also disclosed.

  • Patent number: 8545928
    Abstract: A method and system for including a double layer security mark in digital document data defining an image of a document to be printed and in the printed document. A fluorescence mark region including a fluorescence mark is defined using first and second metameric colorant mixtures. Variation in colorant spatial coverage between the first and second metameric colorant mixtures results in colorant-free areas that define the fluorescence mark due to substrate fluorescence under UV illumination. The fluorescence mark region is modified to define a double layer fluorescence mark region including the fluorescence mark and also including at least one visible light object defined by a third colorant mixture. The third colorant mixture is added to the fluorescence mark region by masking the colorant-free areas of the fluorescence mark region to prevent writing of the third colorant mixture data to the colorant-free areas to avoid disturbing the colorant-free areas.
