A method for producing pigments having a specified contour, comprises the steps of creating a pigment layer on a starting substrate; detaching from the starting substrate; and structuring the pigment layer into a plurality of the pigments; characterized by bringing into contact the pigment layer with an intermediate substrate, wherein the pigment layer adheres at least in sections to the intermediate substrate; and separating intermediate substrate and starting substrate.

Method for producing pigment fragments with a predefined internal and/or external contour, and pigment fragments

A platelet-shaped pigment with a layer construction comprises the following layers in the order, optionally a carrier substrate; a transparent embossing lacquer layer with an embossed relief structure; a reflection-increasing coating which follows the relief structure and forms a reflecting microstructure, wherein the reflecting microstructure is present in the form of a mosaic of a multiplicity of reflecting mosaic elements and the reflecting mosaic elements do not reflect the incident light in the direction of the specular reflex, regarding the plane of the platelet, but in a spatial direction deviating therefrom and respectively have a lateral dimensiongreater than 2 &#x3bc;m.

A method for detecting the fitness for circulation of a value document, includes the steps of: a) carrying out a measurement of the thickness on a tactile structure of the value document, and b) comparing the measured thickness with a previously known target thickness of the tactile structure in order to establish the fitness for circulation.

Method and apparatus for detecting the fitness for circulation of a value document

A security paper for manufacturing value documents has a planar substrate equipped on one surface with an anti-forgery means based on a carrier foil having an optically variable security feature. The anti-forgery means and a partial substrate area surrounding the anti-forgery means is furnished with a dirt-repellent radiation-curing first lacquer substantially not influencing the perceptibility of the optically variable security feature. The layer thickness of the lacquer lying is in a range of 0.7 to 2 micrometers. The radiation-curing first lacquer is may be a UV-cross-linking lacquer which after cross-linking is high-gloss. The substrate can be furnished on its surface lying outside the anti-forgery means with a dirt-repellent second lacquer and optionally partly overlaps the first lacquer in the region of the partial substrate area surrounding the anti-forgery means. The second lacquer involves either a physically drying, water-based dispersion lacquer, or a UV-cross-linking lacquer, and has a matt impression.

Security paper, value document obtainable therefrom and method for manufacturing said paper and document

A method or apparatus for examining a security element of a value document involves at least one optical property of the security element influenceable by a magnetic field. The value document is transported through a magnetic field which is inhomogeneous transversely to the transport direction and/or is changed time-dependently. An image of at least one portion of the value document having the security element is captured and image data describing the image are formed. The optical properties of the security element are influenced by the magnetic field, and the image data is checked whether they have a location dependence transverse to the transport direction corresponding to the location dependence of the magnetic field and/or have a location dependence in the transport direction corresponding to the time dependence of the magnetic field.

Device for examining a value document and method for examining a value document

The invention relates to a value document, especially a banknote, having a sequence of layers into which visually and/or mechanically perceptible identifiers in the form of patterns, letters, numbers or images are introduced by the action of laser radiation. According to the present invention, the sequence of layers includes a marking layer () composed of an ink mixture () exhibiting a laser-radiation-absorbing mixture component () and a laser-radiation-transparent mixture component (), the identifiers being visually and/or mechanically perceptible due to an irreversible change in the optical properties of the ink mixture (), effected by the action of the laser radiation.
