  • Patent number: 10322601
    Abstract: A value and safety document comprises a substrate having a front side and a back side. An ink layer is applied to the front or back sides of the substrate. A first motif is incorporated into the ink layer, and is combined with a second motif. The second motif is arranged on the same side of the substrate as the first motif. The second motif is configured in the form of an emboss structure comprising a plurality of raised emboss elements having areas of different orientation. The emboss structure forms the second motif having a second tilt or motion effect, by different groups of emboss elements, having different characteristic parameters, reflecting incident light in different spatial areas. The emboss elements have respectively a lateral dimension of less than 30 ?m and a height of less than 10 ?m. The first motif is adapted at least partially to the second motif.

  • Patent number: 9669647
    Abstract: A security element includes an optically variable structure having a multiplicity of first embossed structures each including at least two flanks which converge at at least one certain angle. In at least one first partial region of the optically variable structure, at least one flank of the first embossed structures respectively has at least one additional embossed structure which is mounted on the flank of the first embossed structures or inserted into the flank of the first embossed structures. The geometry of the at least one additional embossed structure is executed to be at least near-inverse to the geometry of that flank of the first embossed structure on which the at least one additional embossed structure is mounted or inserted.

  • 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: 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: 8524039
    Abstract: A screen for producing two-level watermarks is produced by completely closing part of the screen with a viscous sealing compound, which is subsequently cured actively or passively. At the thus closed partial areas of the screen, paper deposit is hindered during papermaking so that the finished paper appears light in transmission in the areas. A mask is used for exactly positioning the sealing compound in the partial areas of the screen and/or for curing the sealing compound only in the given partial areas, whereby in the latter case the uncured areas of the sealing compound are washed out.

  • Patent number: 8511561
    Abstract: Scanning apparatuses for scanning bar codes applied to documents have a reflector arrangement having either a variable reflection element or a light guide system. The reflection element or light guide system serves to deflect the beam path of the electromagnetic radiation emitted by a radiation source or an illumination device in the document plane along a line substantially perpendicular to the feed direction of the document, or to capture it, and to relay it to a detector.

  • 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: 8100436
    Abstract: The invention relates to a security element with an optically variable structure, which has an embossed structure and a coating, wherein the embossed structure and the coating are combined such that at least parts of the coating are completely visible upon perpendicular viewing, but are concealed upon oblique viewing. This embossed structure has nonlinear embossed elements, which are combined with the coating such that when changing the viewing direction different pieces of information become visible.
