Abstract

FIELD: methods for producing securities, protected from forgery, such as a banknote, identity card, note.

SUBSTANCE: method for protecting securities from forgery is realized by bending security, made with protecting element, consisting of at least two portions with through micro-apertures. These portions are combined with each other and/or with a separate decoding control sample with production of image visible in light, consisting only of combined portions of micro-apertures, and carrying information, making it possible to identify the security. Micro-apertures are made in form of rectangles with rounded narrow sides with transverse dimension from 10 micrometers to 500 micrometers, and with longitudinal dimension from 10 micrometers to 10 millimeters. If one of portions is shifted relatively to another one and/or relatively to separate decoding control sample, changing image is produced - unfolding, compressing or stretching wholly or partially, or a row of images different from each other.

EFFECT: increased protection level of securities.

Description

The invention relates to methods for manufacturing counterfeit securities, such as a banknote, an identity card, bills, etc.

A known method of protecting securities and documents (patent WO 2004/089644 A1), which consists in the fact that they are applied to a specific area of the protective element, consisting of a series of round through holes. On the valuable document or on the decoder there is a second section with similar holes, and the first section and the second section are arranged so that when they overlap, information becomes visible when the observer looks through the perforated holes in the first section and the second plot or decoder.

However, the displacement of these sections with round through-holes with respect to each other by a distance greater than the diameter of the holes leads to the disappearance of the image, which is a limitation of the protective properties of the protective element.

The proposed method due to the fact that in it security holes are made of arbitrary shape, is devoid of this drawback. In the area of intersection of holes of arbitrary shape, for example, rectangles with rounded narrow sides, a through hole will always be observed in the lumen, which allows to improve the protective properties of microperforation. The result of the application of the proposed method of protection is to increase the protective properties of a banknote, security or document.

The specified technical result is achieved by the fact that in the method of protecting securities from counterfeiting by bending a security made with a security element consisting of at least two sections with through micro-holes and combining these sections with each other and / or with a separate decoding control sample with the receipt of the image, consisting of only compatible sections of the micro-holes, and carrying information that allows you to identify a security paper, according to the invention, the micro-holes in the form of rectangles with rounded narrow sides with a transverse size from 10 to 500 microns and a longitudinal from 10 microns to 10 mm, and when one of the sections is shifted relative to the other and / or a separate decoding control sample, a changing image is obtained - expanding, contracting or stretching in whole or in part , or a series of images differing from each other, as well as the fact that when applied to a banknote, security paper or document more than two sections with through micro-holes are obtained when combined and consistently with each other in the lumen of the observed image each time a different type.

The invention is illustrated by the accompanying drawings, in which:

figure 1 is a schematic illustration of a method of inflection of a security to combine areas with micro-holes;

figure 2 - image that occurs when combining sections with micro-holes.

The invention relates to a security method that allows you to protect a security paper from counterfeiting due to the fact that individually taken portions with micro-holes do not carry ordered information, and the encoded image appears only when they are superimposed on each other and / or on a separate decoding control sample and even with their significant mutual displacement.

The overlay can be done by special marks or manually by visual inspection of its result, which allows for genuine banknote, security paper or a document with the security element applied when it is bent and combined, for example, sections of the security element located on the corners of one of the sides of the security, easily achieve preliminary alignment of the perforated areas, and then precisely combine them to ensure maximum visual effect. A similar result can be achieved using a separate decoding control sample. No auxiliary precision equipment is required to implement this protection method. When one of the sections is shifted relative to another and / or a separate decoding control sample, a changing image is obtained - expanding, contracting or stretching in whole or in part or a series of images that are different from each other. When applying to a banknote, security paper or document more than two sections with through micro-holes, they are obtained by combining them sequentially with each other, the image observed in the lumen each time of a different kind.

In addition, by varying the shape and angle of the axis of the holes, it is possible to achieve that when the sections shift relative to each other, the image observed by the lumen, consisting of the aligned sections of the microholes, will gradually change - compress, stretch or expand.

Figure 1 shows a diagram of a method for bending a security paper 1 in the direction of the arrow, used in the implementation of the proposed security method for combining sections 2, 3 with micro-holes and superimposing these sections on top of each other.

Figure 2 shows the image that occurs when implementing the proposed method of protection, when combining areas on which the micro-holes are applied.

The proposed method of protecting securities allows you to effectively determine their authenticity. The manufacture of fakes with this security element will cause difficulties due to the multivariance of obtaining a combined image embedded in the used security element.
