Cleanliness class zones 7 securities 4 is selected from the condition of ensuring the possibility of obtaining the effect of specular reflection of light from zones 7 during playback on securities 4 through sections of the printing form 2 with the same location of DEATH 6. 3 C.p. f-crystals, 2 Il.

The invention relates to the field of printing and can be used for mass production and simultaneous protection against forgery, e.g., banknotes, credit documents and other securities with the possibility of determining their authenticity through visual inspection by the naked human eye.

Currently, direct financial losses of the developed countries due to tampering (unauthorized production and putting into circulation on a large scale) notes, loan documents and other securities amount to considerable sums. This is due to the fact that the modern level of development of computational, analytical and copying equipment allows to reproduce with a high degree of identity almost any valuable paper in unlimited quantities at relatively low costs.

Especially this is a major problem in cases of mass is the CTL should be minimal. In addition, in this case, the protective elements (tags) must promptly be detected via an inexpensive and accessible to a wide range of user controls. Optimally, to provide the ability to control specific characteristics of the protective elements (tags) through visual inspection by the naked human eye.

Currently, there are various methods and means of protection against forgery of valuable products, in particular banknotes, credit documents and other securities.

For the selected group of the protected items, such as banknotes, securities, etc., used protective elements (tags), as a rule, are divided into three groups: pre-press, printing and finishing.

Prepress protective elements are composition, paper, watermarks, metallic thread, color and glow in ultraviolet rays fiber, confetti, etc.

To print protective items include:

elements that implement the methods of graphic reproduction, including microprinting, combined code and drawings etc.;

elements implemented directly by the methods of printing, including through deep, high) optical effects;

- applied printing ink.

The combination of finishing protective elements may include embossing, coating, film coating, labeled items, etc.

A significant portion of the known methods and means of protection against forgery are the ways of protection through protective metal labels. Moreover, the label may be formed as a direct application of the label (such as paint) to protect the product and applying the above mentioned product is separately manufactured from the material of the label means, for example, in the form of strips.

In particular, there is a method of protection of banknotes against counterfeiting, according to which the banknote as a protective element is applied a special image by a magnetic ink. Registration of this mark is carried out using a magnetic detector (GB, N02079506, CL G 07 D 7/00, 1982).

A disadvantage of this known from the prior art means for the protection of banknotes against counterfeiting and method of its implementation include the following:

- it can be quite easily reproduced and imitiroval with a high degree of identity to the original using modern widely known from the prior art means, accessible to a wide range of sinter the means of registering the presence of protective elements (magnetic detectors), which not always has a massive user.

Known personal protection documents in the form of a perforation pattern which is recognizable irregularities. The perforation is carried out using a laser beam, on the basis of the usual pattern, the management of the laser is carried out by computer in such a way that each perforation has an individual irregular, depending on the original value (DE, application N03628353, CL 44 F 1/12, 1988).

The disadvantages of this known from the prior art protection against forgery and method of its implementation are as follows:

- limited functionality due to the fact that through such a protective element it is advisable to protect only a limited amount of products due to its poor performance (because the speed pointwise laser burning significantly below methods for forming labels simultaneously over the entire area of media).

- the need to use expensive technological equipment for the industrial implementation of the protective element on the protected product;

to check the availability of recognizable irregularities such protective label, you must use special is ment, protected from fraud, according to which the remedy is performing as applied at least on one side of the sheet of media reflecting layer, hosting groups of grains, resulting in the surface of the reflecting layer has a varying reflectivity. Label, formed by groups of grains, can be read by a machine (EP patent EPO N0155982, CL G 06 K 19/05, 1985).

This is known from the prior art protection of documents against forgery has a number of significant limitations to its use. In particular, significant technical problems arise in the detection of protective label with the required resolution due to the mounting of the grains in the process of grinding and coating. While increasing their dispersion increases the spectral width of the image in the region of low spatial frequencies.

In addition, it is impossible to carry out operational control of the presence and specific features formed according to the method of the protective label without the use of special means of control.

The prior art also widely known printing plates for the production of securities, including made in funkcj, forming a protective surround the figure of a given configuration (EN, No. 2004918, CL G 03 F 7/00, 1993, RU, No. 94020443, CL 23 To 26/00. 1996, SU, No. 286497, CL G 03 F 7/00, 1970, SU, No. 636861, CL G 03 F 7/00, 1983, SU, No. 439098, CL G 03 F 7/00, 1974).

The disadvantages known from the prior art printed forms should be attributed to their limited functionality, due to the fact that we get through these printed forms prints on securities products are limited (low) degree of protection against forgery, which makes them practically unusable for large-scale production of valuable products, such as banknotes, without the use of additional remedies. And this complicates the process and increases the cost of manufacture.

Modern technological processes in the field of Photocopying and/or scanning techniques has led to the fact that some of the above remedies is no longer sufficient to prevent unauthorized issuance of securities and documents. Since the advent of color photocopy machines with high performance manufacturers of securities began to focus on the creation of documents zones, giving a moiré effect in digital kopirovani effect distorts the original image and allows you to visually distinguish the copy from the original. The moiré effect occurs when parallel lines or line, the gap between which is different from the element discretization (sampling), intersect perpendicularly to one of the axes of the sampling machine. Reading of information is thus broken and the original image is distorted. In particular, there is formed an uneven change shades and colors.

The main disadvantages of these technical solutions should include the fact that the appearance of such moire effects are quite hard to predict, since it largely depends on the technical characteristics and adjustments used to play equipment.

Closest to the claimed technical solution is the method of forming the optical and mechanical elements of the protection of securities from a fake, printed form to implement the method and securities derived on their basis, deriving from a patent RU No. 2172679, 2000

Stemming from the above-mentioned patent method of forming the optical and mechanical elements of the protection of securities from a fake (mainly at high printing) is that the functional layer of the printing form to create the printing elements in the form of visually perceived the second configuration, in this case, at least one section of the side surface of the restriction profile of at least one printing element, mechanically create additional security elements, by means of which provide a change in reflectivity of the respective zones paint layer formed on the imprint of the securities in the area of the location mentioned additional protection elements.

Known from the above patent printed form for the production of securities with opto-mechanical elements of protection against forgery includes made it functional layer of the printing elements in the form of visually perceived specialized structures through which the imprint of the securities formed a protective figure of a given configuration, in this case, at least one section of the side surface of the restriction profile of at least one printing element mechanically created additional security features that ensure the changing reflectivity of the respective zones paint layer formed on the imprint of the securities in the area of the location mentioned additional protection elements.

Realizowania with opto-mechanical elements of protection against forgery includes made in formed on the functional surface of the paint layer protection elements in the form of visually perceived relevant agencies, forming a protective pattern of a given configuration, in this case, at least one section of the side surface of the restriction profile of at least one core structure formed additional security features in the form of predefined areas with reflective, non-adjacent to these zones plots the lateral surface of this structure.

The disadvantages of these (known from the prior art technical solutions should include the complexity of the implementation of technological facilities, as well as the above-mentioned drawbacks inherent remedies that implements an unauthorized reproduction (copying) moire effect.

The basis for the claimed invention was based on the task of creating such method of forming the optical and mechanical elements of the protection of securities from a fake, printed forms to implement the method and securities received based on them, by means which would provide formation on a printed impression securities additional remedies (in the form of additional security features and implemented by these elements optical effects other than the moire effect) simultaneously with formation of the primary visual vesprini what you are naked to the human eye.

The solution of the problem (in relation to the subject of the invention: “device”, i.e., the “securities”) is ensured by the fact that securities with opto-mechanical elements of protection against forgery, including made in formed on the functional surface of the paint layer protection elements in the form of visually perceived specialized structures, forming a protective pattern of a given configuration, with at least one portion of the surface bounding the profile, at least one profile of a structure formed additional security features in the form of predefined areas reflecting the incident light flux, other than adjacent to these areas of the surface sections of this structure, according to the invention mentioned reflective zones of the location of additional security features provided through the implementation of these zones with a high purity in relation to adjacent areas of the surface of this structure, and roughness, and the spatial orientation of the areas of the additional protection elements selected from the provision of the mirror effect of the incident aprosodia on the imprint of securities through sections of the printing form with a similar arrangement of additional elements of protection and is governed by the roughness of the surface of the latter.

Suitable areas additional protection elements to be performed on parts of the pair of lateral surfaces referred to specialized structures with their tops.

Valid zone additional protection elements to be performed on parts of the pair of lateral surfaces referred to specialized structures with their bottom parts.

The profile of the pair of lateral surfaces referred to specialized structures with their bottom parts to perform optimally straight and positioned orthogonal to the side surface of the connecting profile structures.

Zone of the location of additional security features can be performed on the upper surfaces referred to specialized structures.

Zone of the location of additional security features can be implemented and curvilinear forms.

The invention is illustrated in graphic materials.

Fig.1 is a cross section of a fragment of volumetric protective pattern configuration of a functional layer of the printing form.

Fig.2 is a cross section of a fragment of volumetric protective pattern configuration formed colored layer on the functional surface of the securities by the printing form according to Fig.1.

The claimed method forms is implemented as follows.

The functional layer 1 of the printing form 2 create the printing elements 3 in the form of visually perceived specialized structures through which to imprint securities 4 port protective figure of a given configuration. In this case, at least one section of the side surface 5, the bounding profile, at least one printing element 3 mechanically create additional elements 6 protection. By means of additional elements 6 of defense to provide the change in reflectivity of the respective protection zones 7 forming the paint layer 8 on the imprint of securities 4 in the area of the location mentioned additional protection elements 6. Additional security elements 6 create by improving the cleanliness class of the relevant parts of the side surface 5 of printing elements 3 of the printing form 2 in areas where additional protection elements 6. The class purity mentioned sites in areas where additional protection elements 6 increase within such limits, to ensure the possibility of obtaining the effect of specular reflection light from the respective protection zones 7 of the paint layer 8 on the imprint valuable butalnital security features 6.

The claimed printing form to implement the method includes executed in the functional layer 1, the printing elements 3 in the form of visually perceived specialized structures through which the imprint of securities 4 is formed a protective figure of a given configuration. In this case, at least one section of the side surface 5, the bounding profile, at least one printing element 3, mechanically created additional elements 6 protection. Additional elements 6 protection is made with the possibility of changing the reflectivity of the respective zones 7 forming the paint layer 8 on the imprint of securities 4 in the area of the location mentioned additional elements 6 protection. Additional elements 6 protection made in the form of plots of the lateral surface 5 of printing elements 3 with a high purity with respect to related sections of this lateral surface 5. The class purity of additional elements 6 protection chosen from the condition of ensuring the possibility of obtaining the effect of specular reflection light from the respective zones 7 of the paint layer 8 on the imprint of securities 4 that (i.e., zone 7) are reproduced should be noted, what class of purity plots of the lateral surface 5 of printing elements 3 in the locations of the additional elements 6 protection, as a rule, is governed by the optical properties of paint used for forming the paint layer 8 on the imprint of securities 4.

The claimed printing form 2 for the production of securities 4 can be obtained by various known from the prior art methods and means. For example, by photo - and/or rentgenoterapii, laser engraving, mechanical way by processing the functional layer by cutting using superprecision equipment. Additional elements 6 protection are formed solely by a mechanical method using mainly a special diamond or abrasive tool after forming the aforementioned printing elements 3 in the functional layer 1 of the printing form 2.

The claimed valuable paper (reproduced on the basis of the claimed method and the printing form 2 for its implementation) includes made in a formed on its functional surface 9 a paint layer 8 security features in the form of visually perceived core structures 10, forming a protective figure sagapo least one core structure 10 formed additional security features in the form of predefined areas 7 with a reflectivity that is different from adjacent to these zones 7 plots the lateral surface 11 of this structure 10. Mentioned reflectance zones 7 location of additional security features provided through the implementation of these zones 7 with a high purity with respect to adjacent portions of the side surface 11 of the considered structure 10. Cleanliness class zones 7 location additional protection elements selected from the condition of ensuring the possibility of obtaining the effect of specular reflection of light from these zones 7 of the paint layer 8 in the process (i.e., zones 7) play on the imprint of securities 4 through sections of the printing form 2 with a similar arrangement of additional elements 6 protection and regulated by the roughness of the surface of the latter (i.e., items 6). Zone 7 location of additional security features can be located on any of the parts of the surface profile of the considered structure, for example, as shown in the graphic materials. In addition, through said additional elements of protection on the field of securities may be sformirovat from the discussion above, that simplifies the process of monitoring the authenticity of the user. The width of the zones additional protection elements (located on side surfaces of the specialized structures), usually selected such that when looking at the field of securities perpendicular to the surface of the mirror effect are not visually perceived by the naked eye (only possible machine control using a special optical detectors), but when viewed perpendicular to the mentioned side surface profile of the structure (i.e., at an angle to the field of securities) the effect of specular reflection of the incident beam of light is visually perceived by the naked eye of the user.

The physical principle of the formation of the imprint securities 4 additional security features (i.e., protective zones 7) declared by the printing plate 2 is based on the following.

Due to the presence of the side surfaces 5 of printing elements 3 of the printing form 2 additional elements 6 protection formed on a printed impression (securities 4) the paint layer 8 will be different (for example, the height of the specialized structures 10 of the paint layer 8) reflectivity. While the protective zone 7 core strsta 11 referred to specialized structures 10 will reflect the incident luminous flux diffuse. This provides:

firstly, the formation of certain parts of the protective figure visually perceived grayscale plots (due to reflections and interference of light beams /threads/ with different structure);

- secondly, due to the presence of zones 7 mirrored (and, respectively, formed through these zones 7 directed light beams) will be observed effect of the emergence of “Sunny Bunny” when the user changes the angle received on securities 4 of the drawing process control authentication securities 2 (i.e., manifests secondary optical effect, visually perceived by the user even when a very small width of the zones 7 and disappear when unauthorized reproduction of securities 2, for example, by heliographic equipment).

The present invention does not exclude the possibility of manufacturing the printing plate 2 with at least a part of the visually perceived specialized structures (i.e. printing elements 3) with different relative to each other in width, whereby the valuable paper 4 can provide additional security by providing records from which I can be laid on any part of the protective figure and read from this plot by a machine.

In addition, in the manufacture of printing plates 2 with at least a part of the visually perceived specialized structures (i.e. printing elements 3) with different relative to each other in depth, you can provide additional security by ensuring the recording imprint code given information in the form of a set of stripes with different colors. This code may also be laid on any part of the protective figure and read from this plot, for example, by a machine.

A high degree of protection is guaranteed not due to any unique materials, methods and means of formation and detection of security marks, but solely due to the extremely low probability of repeated reproduction is formed by patentable inventions protection elements with the effect of “Sunny Bunny”, as this effect is not reproduced by modern heliographic equipment.

Thus, the above data confirm that the implementation of the use of the claimed technical solution the following cumulative conditions:

objects embodying the claimed technical solution in their implementation, prednaznachennyh securities (mostly bills) from forgery;
