The present invention relates to a security element () for security papers, value documents and the like, having a microoptical moir&#xe9;-type magnification arrangement for depicting a moir&#xe9; image () having one or more moir&#xe9; image elements (), having

Security element

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

Security element, value document comprising such a security element, and method for producing such a security element

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 () that is broken down into two or more partial target images (), having

Depiction arrangement

The present invention relates to a depiction arrangement for security papers, value documents, electronic display devices or other data carriers, having a raster image arrangement for depicting a specified three-dimensional solid () that is given by a solid function f(x,y,z), having a motif image that is subdivided into a plurality of cells (), in each of which are arranged imaged regions of the specified solid (), a viewing grid () composed of a plurality of viewing elements for depicting the specified solid () when the motif image is viewed with the aid of the viewing grid (), the motif image exhibiting, with its subdivision into a plurality of cells (), an image function m(x,y).

Representation system

An anti-counterfeit printed matter forming an invisible image that can be visualized clearly and prevents a visible image from impeding visibility of a visualized invisible image. In the anti-counterfeit printed matter according to this invention, a plurality of object elements are arranged at a predetermined pitch in a matrix, each object element including a first and second object arranged along a first direction on both sides of a boundary at a center, opposing each other, and third and fourth objects arranged along a second direction perpendicular to the first direction on both sides of a boundary at the center, opposing each other. The first object and the second object, and the third object and the fourth object of each object element have a negative/positive relationship. The first object and/or the second object forms a first invisible image. The third object and/or the fourth object forms a second invisible image.

Endless material for security elements

The present invention relates to a depiction arrangement for security papers, value documents, electronic display devices or other data carriers, having a raster image arrangement for depicting a planar target image that is given by an image function f(x,y), having a motif image that is subdivided into a plurality of cells (), in each of which are arranged imaged regions of the target image a viewing grid () composed of a plurality of viewing elements for reconstructing the target image when the motif image is viewed with the aid of the viewing grid (), the motif image exhibiting, with its subdivision into a plurality of cells, an image function m(x,y).

The present invention relates to a security element for protecting valuable articles, having a first and a second authenticating feature. The first authenticating feature comprises a first arrangement having a plurality of focusing elements present in a first grid, and a second arrangement having a plurality of microscopic structures present in a second grid. Here, the first and second arrangement are disposed in such a way that the microscopic structures of the second arrangement are seen magnified when viewed through the focusing elements of the first arrangement. The second authenticating feature is machine and/or visually verifiable and is not influenced by the first arrangement of the first authenticating feature.

Security element and method for the production thereof

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.

The present invention relates to a security element for security papers, value documents and the like, having a microoptical moir&#xe9; magnification arrangement () for depicting a three-dimensional moir&#xe9; image () that includes, in at least two moir&#xe9; image planes spaced apart in a direction normal to the moir&#xe9; magnification arrangement, image components (), having a motif image that includes two or more periodic or at least locally periodic lattice cell arrangements having different lattice periods and/or different lattice orientations that are each allocated to one moir&#xe9; image plane and that include micromotif image components for depicting the image component () of the allocated moir&#xe9; image plane, for the moir&#xe9;-magnified viewing of the motif image, a focusing element grid that is arranged spaced apart from the motif image and that includes a periodic or at least locally periodic arrangement of a plurality of lattice cells having one microfocusing element each, wherein, for almost all tilt directions ({right arrow over (k)}), upon tilting the security element, the magnified, three-dimensional moir&#xe9; image () moves in a moir&#xe9; movement direction ({right arrow over (v)}) that differs from the tilt direction.

This invention relates to a value document, in particular a bank note, having a value document substrate and at least two different feature substances for checking the value document. According to the invention, a first feature substance is incorporated into the volume of the substrate of the value document. A second feature substance is formed by a luminescent substance which is applied to the value document substrate in the form of a coding.

Value document

The present invention relates to a security element () for security papers, value documents and the like, having a micro-optical moir&#xe9; magnification arrangement having a motif image that consists of a periodic or at least locally periodic arrangement of a plurality of micromotif elements () that is planar or applied on a curved surface, and a periodic or at least locally periodic arrangement of a plurality of microfocusing elements () that is planar or applied on a curved surface, for moir&#xe9;-magnified viewing of the micromotif elements () of the motif image, the arrangement of micromotif elements () and/or the arrangement of microfocusing elements () exhibiting, in the planar case, no symmetry axis in the plane of the arrangement in its periodic or at least locally periodic regions.

The present invention relates to a grating image () for depicting at least one unscreened halftone image having multiple brightness levels, the grating image exhibiting multiple grating fields (---) that include in each case an electromagnetic-radiation-influencing grating pattern composed of a plurality of grating lines and that, when illuminated, produce in each case an areal region of the halftone image having the same brightness level.

Grid image and method for the production thereof

A security element, preferably for documents of value, which at least has one area with a diffraction structure, which under specific viewing conditions reconstructs a diffractive image. This area has subareas, which do not take part in the reconstruction of the diffractive image, and which represent a recognizable information. Essential is that the information represented by the subareas is recognizable mainly only under the viewing conditions, under which the diffractive image can be perceived.
