  • Patent number: 11110734
    Abstract: A security element for securing security papers, value documents and other data carriers, having a lenticular image that, from different viewing directions, displays at least two different appearances. The lenticular image includes a lens grid composed of a plurality of microlenses and a radiation-sensitive motif layer arranged spaced apart from the lens grid. The radiation-sensitive motif layer includes, produced by the action of radiation, a plurality of transparency regions that are each arranged in perfect register with the microlenses of the lens grid. Outside the transparency regions produced by the action of radiation, the radiation-sensitive motif layer is opaque and patterned in the form of a first motif such that, when the security element is viewed through the lens grid from a first viewing direction, the first motif is visible as the first appearance.

  • Publication number: 20210074109
    Abstract: A method for verifying an object is furnished with a security element in which the security element is manufactured in a multi-step method with register variations and contains in a check field an individual characteristic feature of the security element in the form of a superimposition of at least two areal regions. The check field of the security element is optically captured by a camera, the area proportions of the superimposed and not superimposed areal regions are determined and from it a check value for the individual characteristic feature of security element is formed and compared with a reference check value, on which a verification result for the object furnished with the security element is created.

  • Patent number: 8936846
    Abstract: 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 (22) composed of an ink mixture (24, 26) exhibiting a laser-radiation-absorbing mixture component (26) and a laser-radiation-transparent mixture component (24), the identifiers being visually and/or mechanically perceptible due to an irreversible change in the optical properties of the ink mixture (24, 26), effected by the action of the laser radiation.

  • Patent number: 8875628
    Abstract: The invention relates to a data carrier, especially a value document or security paper, having a substrate (20) and, applied on the substrate, a coating (12) into which, through the action of laser radiation, markings (14) are introduced in the form of patterns, letters, numbers or images. According to the present invention, it is provided that the coating (12) includes a laser-radiation-absorbing layer (22) and a printing layer (24) that is disposed over the absorbing layer and that is at least partially transmissive to the laser radiation, and that the printed substrate is pressed (26) during or after the imprinting of the at least partially transmissive layer (24).

  • Patent number: 8622433
    Abstract: The invention relates to a value document, such as bank note, passport or the like, which has a security paper and a marking produced with the help of a laser, the security paper having at least one partial area with a coating, and the marking extending over the border area between coating and security paper. Further, the invention relates to a security paper and methods for producing an inventive value document and security paper.

  • Patent number: 8400673
    Abstract: The invention relates to a value document, especially a banknote, having an individualizing mark that is applied at least once each to the front and the reverse of the value document. Here, at least one of the individualizing identifiers applied to the front and reverse is applied to the value document with a non-contact method.

  • Patent number: 8251404
    Abstract: The present invention relates to a data carrier, especially a value document, such as a banknote, an identification card or the like, having a security element (20) that exhibits a print image (22) and a laser marking (24) at least partially overlapping the print image (22). According to the present invention, the security element (20) further exhibits, at least partially overlapping the print image (22), a laser modification area (26) that is in register with the laser marking (24) and in whose overlap area (28) with the print image (22) the visual appearance of the print image (22) is modified by the action of a laser beam.

  • Patent number: 7537161
    Abstract: The invention relates to a method, in which from two images of a security element, which are recorded with right-handed and left-handed circularly polarizing filters, a differential image is produced, on the basis of which the authenticity of the security element is tested, and an apparatus for carrying out the method.

  • Publication number: 20040245343
    Abstract: Coding 1, in particular a bar code, is printed by intaglio printing on substrate 10, in particular a bank note. Individual coding areas 2, 3, 4 differ in their ink layer thickness. The printing ink contains luminescent and/or electroconductive and/or x-ray absorbing and/or infrared radiation absorbing substances, so that the different ink layer thicknesses can be differentiated by different signal intensities.
