The invention relates to the media, protected from fraud, and ways of protection against forgery of printed products, such as securities, banknotes, identity documents, both paper and polymer-based.

A known method of manufacturing securities DE 3208204 A1, the invention relates to the protection from unauthorized copying, offset printing method. As the media used transparent paper or other transparent carrier material coated on both sides of periodic or almost periodic drawings, consisting of dots or lines. For the application you are using an exact alignment of images on the front and back sides of the media are made available for duplex printing. It is therefore proposed that the periodic structure of the lines, which with proper correlation in the transmitted light has the appearance of fine lines, and with a slight shift patterns in the case of forgery get moire image.

The disadvantage of this technical solution is the necessity of keeping an accurate register of the elements of the front and back side, which complicates the technological process of production, as manufacturers are forced to only use the equipment for double-sided printing, and increases the probability of appearance the Oia marriage. It should also be noted that the use of double-sided printing because of the way technology does not allow to use images with a line width of less than 40 microns.

Similar technical solution is presented in US 6494491 B1, 17.12.2002, in which to obtain a latent image graphical elements forming the protective element are arranged so that a part of the elements has a slight offset relative to the other elements. For the manifestation of the latent image is using a transparent material to which applied the lattice corresponding to the position of the graphic elements that do not have offsets. When applying such material to the media elements of the lattice close the graphical elements of the media, without bias, and the latent image is shown as positive. When applying a transparent material with a shift, so that the elements of the lattice of closed elements with an offset, the latent image is shown as negative.

The disadvantage of this technical solution is the necessity of combining without distortions transparent material with sealed area, making it difficult to identify protective element by an unskilled user.

Closest to the claimed technical solution is the invention described in patent RU 2386544 C1, 20.04.2010, where PR is needed protective element for printed products, containing multilayer transparent polymer film with the first rasterized image, made on the upper surface of the upper layer film with a resolution of the same order as the thickness of the film, and the second rasterized image is made on the bottom surface of one of the underlying layers of a polymeric film and/or on the surface of the protected products, which is a protective element, and the second rastrirovano image is located so that when the observation image on the reflection from different angles or in the lumen of the observed image gradually changes from positive to negative or Vice versa, with the first and second rasterized image is made transparent, and/or semi-transparent and/or reflective and/or luminescense, and/or relief. A method of manufacturing a protective element includes applying image on the surface of the film layers by methods of local carbonization and/or engraving with a laser beam in the surface layers of the film thickness of 1-10 μm, and/or methods method copy.

The disadvantage of this technical solution is the limitation on the formation method of raster elements, namely the impossibility of creating such items without the use of laser treatment that substantially ograniczenie the scope of protected printing products.

The problem solved by the invention, the enhancement of security products through the use of high-resolution images are not available for digital printing devices and commercial printing, as well as obtain a new optically variable effect and/or the effect of motion, as well as improving technology and reducing the cost of the protective element by forming a raster printing method.

This task is solved by the features set forth the claims. Preferred variants of the medium and methods of its manufacture are presented in the dependent claims.

The media protected against forgery, has at least one transparent region, on both sides of which there are graphic elements in the form of a linear screen, forming a periodic structure of a high-resolution, according to the invention, the graphical elements are formed in the printing method, and after passing through the printing process media retains its flatness, thickness of the applied paint layer ranges from 3 to 10 μm, and the mutual arrangement of these elements is such that they form an image, which is hidden when viewed in reflected light and visible when viewed against the light, and primenenii direction viewing on clearance the image changes from positive to negative and Vice versa and/or change its color completely or partially, and/or an effect of motion monochrome or multi-color moiré patterns. The width of named graphical elements and the amount of clearance between them should be less than or equal to the thickness of the recording medium, it makes use of graphics and high resolution images, since the thickness of the transparent part of the recording medium can vary from 10 to 40 microns.

The transparent area of the recording medium can be made: in the form of single layer or multi-layer polymer film, a transparent or partially dyed or surface; or specially impregnated paper; or filigree watermark.

The image can be formed, broken or curved lines, or dots, or dashes, or graphic primitives, or a combination thereof.

A method of manufacturing a tamper-resistant storage media includes applying at least one transparent region of the carrier graphical elements in the form of a linear raster forming a periodic structure according to the invention the graphical elements cause the printing means on one or both sides of the media, and their relative position is such that they form an image having an optically variable effect.

Graphic elements applied by way of metallographic printing, when due is subject to the following conditions: the depth of the stroke prints must not exceed 14 μm, and the width of the graphic elements must match the order of the thickness of the media. Thus obtained recording media should retain its flatness, and thickness of the paint layer should be in the range of 3 to 10 μm.

In particular, for the formation of the graphical elements on one or both sides of the carrier can be used the method of partial removal using laser technology pre-applied, respectively, with one or both sides of the carrier metal layer.

The claimed technical solution is as follows.
