Definitions
- the invention relates to the field of security printing and can be used in the production of banknotes, securities, passports, excise stamps, credit cards, identification documents and other security printing products, which is an urgent task for the security of our country.
- visual security features based on various visual effects.
- Such visual effects may include, in particular, the effects of movement of a graphic object, the effect of changing the shape and size of a given object, the effect of changing its color, the effect of volume (“3D” effects) or the combination of several visual effects.
- optically variable structures are known from the prior art, for example, from RU 2440248 C1, 08/03/2010, an information carrier is known, including a coating made in the form of printed and three-dimensional rasters.
- the optically variable structure is used as a feature that a person can check without the use of auxiliary means if necessary, along with other features to determine the authenticity of the information carrier.
- Cards that are used for personal identification or for making transactions or providing services can also be used as information carriers.
- an information carrier is known in which the relative position of the printed and three-dimensional rasters ensures the formation of moire in the form of color stripes smoothly transitioning into each other.
- the level of anti-counterfeiting provided by such embossed optically variable security elements can be further enhanced by creating additional visually distinctive effects by deliberately altering the line pattern or altering the embossed structure. Examples of such additional effects are described in WO 97/17211 and WO 02/20280.
- the optically variable effect created by known security elements arises by combining the imprint with a blind embossing, preferably carried out by an intaglio printing plate.
- the disadvantage of blind embossing is that it cannot be integrated into a color printed image obtained by intaglio printing, but can only be used as a separate security feature. This is due to the fact that when applying paint to a printing plate for intaglio printing, it is possible to virtually eliminate the ink from getting into the recesses in the printing plate intended for blind embossing only if there is a sufficiently large distance between its areas intended for blind embossing and the areas rolled up with printing ink.
- the points of the printed raster are placed on the side edges, bottoms or white-space elements of the three-dimensional structure, regardless of the positioning of the printed and three-dimensional rasters, to obtain an image on the carrier that has the form of intersecting linear structures.
- the protective element When observed at an angle of 90 degrees from the plane of the carrier, the protective element is visible in the form of a uniform field of the integral color of the substrate paints, and when the carrier is observed at an acute angle, a change in the color of the element to an integral, mixed color of two substrate paints is observed, while when the carrier is rotated, a moire pattern appears, and depending on the angle of rotation, a color change and/or character of the moire pattern is observed, and the pattern appears in the form of continuous moire stripes, intermittent stripes and/or may have a lattice structure in the form of intersecting moire stripes.
- a similar solution is known from RU 2659989 C1, 08/25/2017.
- the technical result of the invention is the elimination of these disadvantages and the actual development of another technology that is inaccessible for forging documents and securities.
- the problem to be solved by the proposed invention is to create a secure storage medium that would have a new optical visual effect and an increased degree of protection of banknotes, securities, identity cards, passports and other forms of valuable documents on a multilayer media from unauthorized modification using visual features based on a combination of printed and three-dimensional rasterized elements to obtain a stable optically variable image effect.
- the main technical result is the creation of another new security printing technology, expanding the arsenal of technical means for creating visual security features based on various visual effects.
- a protected information carrier with an optically variable effect includes a paper, polymer or combined base containing an area with an applied dot raster regular and/or irregular structure, and the points that make up the raster structure are made in the form of geometric figures containing straight lines, broken, curvilinear lines, several colors, and in the area of the raster structure a three-dimensional raster is applied, made by metallographic inkless embossing and/or relief embossing and/or blind embossing and/or relief printing, and when observing the area at an angle of 90° from the plane of the information carrier a uniformly colored field is visible with the color formed as a result of the synthesis of paints of a point structure, and when observing the zone at an acute angle on a uniform field of the protective medium, the first image is visible, uniformly colored with color or stripes alternating with different colors, in addition, when observing the zone of the information carrier at an acute angle and rotated 90°, the first image changes to
- a method for producing a secure information carrier with an optically variable effect involves applying a zone with an applied dot raster regular and/or irregular structure to a paper, polymer or combined base, wherein the points that make up the raster structure are made in the form of geometric shapes containing straight lines, broken lines, curved lines, several colors, and in the area of the raster structure a three-dimensional raster is applied using the method of metallographic inkless stamping and/or relief embossing and/or blind embossing and/or relief printing at a pressure in the range of 5 - 200 MPa and as materials for creating a three-dimensional raster brass, copper, nickel, photopolymer based on elastomers are used, and when observing a zone at an angle of 90° from the plane of the information carrier, a uniformly colored field with a color formed as a result of the synthesis of paints of a point structure is visible, and when observing a zone at an acute angle on a uniform field of the protective carrier
- An embossing tool such as an embossing stamp or a printing plate, with an engraved surface allowing the production of a protective medium is characterized by the arrangement of the side walls of the first and second multi-directional grids having a profile of any shape, or having a trapezoidal profile with an angle of the side edge to the long base in range from 45° to 75°.

Abstract
L'invention peut être utilisée dans la fabrication de billets de banque, de papiers valeurs, de passeports et autres produits polygraphiques sécurisés. Ce support d'informations sécurisé à effet optique alternant comprend une base papier, polymère ou combinée comprenant une zone où est appliquée une structure matricielle de points. Les points, qui constituent la structure matricielle, se présentent sous forme de figures géométriques, et une matrice tridimensionnelle appliquée dans la zone de la structure matricielle se présente sous forme d'un embossage et/ou d'une impression en relief. Lorsque l'on observe la zone à un angle aigu, on aperçoit dans le champ du support sécurisé une première image colorée uniformément par des bandes. Lorsque l'on observe la zone du support d'informations à un angle aigu et avec une rotation de 90°, la première image se transforme en une seconde image colorée uniformément par une couleur différente de la couleur de la première image, ou par des bandes alternantes de couleur différente qui diffère de la couleur des bandes de la première image. Le résultat technique consiste en une augmentation du niveau de protection.
