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.

Security element with effect pigments and an embossing structure and method for the production thereof

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

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 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 printed data carrier having a printed surface and at least one printed partial surface enclosed thereby on all sides, the surface and the partial surface being printed by intaglio printing and contrasting visually due to an ink layer of varying thickness. The invention likewise relates to the method for producing the data carrier, the printing plate used therefor, and the method for producing the printing plate.

Photoengraved printed data carrier

A data carrier ( ), such as a security, bank notes, ID card or the like, that is embossed in such a way that at least part of said embossment ( ) is shaped like an oblique plane ( ).
