A method for manufacturing a value document includes: providing a value document substrate; printing the value document substrate with magnetically orientable effect pigments which are dispersed in a UV-curable lacquer; the step of exposing the lacquer containing the magnetically orientable effect pigments to a dynamic magnetic field; the step of irradiating the lacquer containing the effect pigments with UV radiation; and optionally the step of embossing the cured or at least partially cured UV lacquer.

Method for manufacturing a value document, value document and printing device

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 &#x3bc;m and a height of less than 10 &#x3bc;m. The first motif is adapted at least partially to the second motif.

A multilayer card-shaped data carrier has a core layer based on paper, with an individualization formed in the layer. At least a part of the area of the data carrier is deformed into a relief which has a viewing angle-dependent optical effect and which extends into the core layer through the cover layer.

Reliefed card-shaped data carrier

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.

Security element comprising a plurality of optically variable structures

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.

Layer-type value document comprising an ink mixture in one layer

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.

Security document

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.

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.

Scanning device for barcodes

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.

Value document comprising a serial number

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 () that exhibits a print image () and a laser marking () at least partially overlapping the print image (). According to the present invention, the security element () further exhibits, at least partially overlapping the print image (), a laser modification area () that is in register with the laser marking () and in whose overlap area () with the print image () the visual appearance of the print image () is modified by the action of a laser beam.

Data carrier with security element and method for the production thereof

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.

Data support with an optically variable structure

The invention relates to a data carrier having a security element that is at lest visually testable and has an embossing in at least a partial area, the embossing being a halftone blind embossing executed by inkless line intaglio printing, and to a method for producing the data carrier and a printing plate for blind-embossing a security element.

Data carrier, method for the production thereof and gravure printing plate

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.

Method and device for checking authenticity of a security element

The invention relates to a data carrier having a security element that is at least visually testable and has an embossing in at least a partial area, the embossing being a halftone blind embossing executed by inkless intaglio printing, and to a method for producing the data carrier and a printing plate for blind-embossing a security element.

Printing plates for all-over printing of large areas by the intaglio printing process, a method for producing the printing plates and data carriers, in particular bank notes, with large-area printed images produced by the intaglio printing process area proposed. Flawless inking is ensured by providing partitions in the engraving of the printing plate which rise up vertically from the base of the engraved area and have at least a height of 50% of the engraving depth. The partitions largely prevent ink from being wiped out of the engraved areas when ink is wiped off the printing plate surface. This permits a large printed area to be covered all over with ink layers on a data carrier. By special arrangement and design of the partitions one can also produce fine structures in the printing area which area recognizable only with magnifying aids depending on the selected distances between the partitions.
