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

A data carrier with an optically variable structure having an embossed structure with raised areas and a first coating contrasting with the surface of the data carrier. The embossed structure and the first coating are so combined that at least parts of the coating are completely visible upon perpendicular viewing but concealed upon oblique viewing so that a tilt effect arises upon alternate perpendicular and oblique viewing. The first coating is provided only in certain areas. Additionally, the optically variable structure has at least in partial areas a second coating likewise contrasting with the data carrier surface and disposed in overlap with the first coating at least in partial areas.

Data carrier comprising an optically variable 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.

The invention relates to a data carrier with a security printed image produced by intaglio printing. The security printed image consists of a plurality of contrasting structural elements disposed in exact register. A first part of the structural elements is designed to be relieflike and tactile and a second part of the structural elements flat and nontactile.

Data carrier with a printed security element and gravure production method thereof

The invention relates to an intaglio printing plate for producing a printing image with at least one engraved area in the printing plate surface, characterized in that the engraved area has one or more structural elements in which the edge area has a greater engraving depth than the inside area, the edge area and the inside area are directly adjacent, and the inside area is designed as a plateau that is lowered relative to the printing plate surface, to a method for producing the printing plates, to a data carrier with a printed image produced by intaglio, and an intaglio printing process.

Gravure printing plate and valuable document produced by the same

A data medium having a printed image is created by the intaglio printing process. The printed image has at least one first ink area with a first ink layer thickness and at least one second ink area with a second ink layer thickness adjacent to the first ink area, such that the ink layer thicknesses are different. The first and second ink areas are separated by a sharp border line invisible on examination with the naked eye, and the ink layer thickness of both ink areas passes through a minimum in the region of the border line.

Gravure process for printing adjacent color surfaces with various color coating thicknesses

The invention concerns a data medium with a printed image created by the intaglio printing process. The printed image has at least one first ink area with a first ink layer thickness and at least one second ink area with a second ink layer thickness adjacent to the first ink area, such that the ink layer thicknesses are different. The first and second ink areas are separated by a sharp border line invisible on examination with the naked eye, and the ink layer thickness of both ink areas passes through a minimum in the region of the border line.

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 ( ).
