摘要： 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.

摘要： A platelet-shaped pigment with a layer construction comprises the following layers in the order, optionally a carrier substrate; a transparent embossing lacquer layer with an embossed relief structure; a reflection-increasing coating which follows the relief structure and forms a reflecting microstructure, wherein the reflecting microstructure is present in the form of a mosaic of a multiplicity of reflecting mosaic elements and the reflecting mosaic elements do not reflect the incident light in the direction of the specular reflex, regarding the plane of the platelet, but in a spatial direction deviating therefrom and respectively have a lateral dimension 1 greater than 2 μm.

摘要： The invention relates to a depiction arrangement for security papers, value documents, electronic display devices or other data carriers, having a grid image arrangement for depicting a target image (40) that is broken down into two or more partial target images (42, 44), having a motif image that is subdivided into a plurality of periodically or at least locally periodically arranged cells (24) in each of which are arranged mapped regions of one or more of the partial target images (42, 44), a viewing grid (22), composed of a plurality of viewing grid elements, that, when the motif image is viewed, reconstructs the complete target image (40) from the mapped regions arranged in the cells (24), the motif image being, independently of the cell subdivision, split into at least first and second microinformation regions (60, 62) in which the cells each include different combinations of mapped regions of the partial target images (40, 42), and the microinformation regions (60, 62) being arranged in the shape of specified image motifs that exhibit information-bearing image patterns whose dimensions are below the resolution limit of the human eye.

摘要： A security element (1) for a security paper, value document or the like, having a carrier (8) which has an areal region (3) which is divided into a multiplicity of pixels (4) which respectively includes at least one optically active facet (5), whereby the majority of the pixels (4) respectively have several of the optically active facets (5) of identical orientation per pixel (4), and the facets (5) are so oriented that the areal region (3) is perceptible to a viewer as an area that protrudes and/or recedes relative to its actual spatial form.

摘要： An optically variable security element wherein the areal expansion whereof defines a z direction standing perpendicularly thereon, and has a multicolored, reflective areal region. The areal region includes two relief structures arranged at different height levels in the z direction. The relief structures are each supplied with an ink coating which produce a different color impression. The ink coating of the relief structure disposed at a higher level is configured in the feature region as a regular or irregular grid with grid elements and grid spaces. The dimensions of the grid elements and/or grid spaces are below 140 μm at least in one direction, so that, in the feature region, for a viewer from at least one viewing angle, the ink coating of the relief structure disposed at a lower level is visible through the grid spaces of the ink coating of the relief structure disposed at a higher level.
