(57) Abstract:

The invention relates to valuable instruments, in particular securities, and solves the problem of creating valuable documents and securities, with evidence of reliability, which can be easily seen by the public, but may not be copied forgers of documents and papers. The invention also solves the problem of creating the characteristic of reliability in the form of a color character and the task of getting the securities of uniform thickness. The inventive features valuable paper for inclusion in a valuable document or other valuable on their own documents. Valuable paper contains resinous sheet substrate on which are printed identification. Sheets of paper are formed on each side or any side of the resin sheet substrate using a suitable adhesive. In a molded valuable paper signs, printed on a sheet substrate, indistinguishable when considering in reflected light, but become visible when considering the transmitted light within the boundaries of the visible spectrum. Securities can be included in a valuable document in which the set of symbols printed on at least one of the external surfaces of the sheets of paper, e.g. adamem light. It is also proposed a method of manufacturing this valuable paper. Graphic print on the resin sheet substrate as a transparent image. Printed sheet substrate formed between the two sheets of paper by means of a suitable adhesive. 4 C. and 29 C.p. f-crystals, 1 tab., 4 Il., 'n

The invention relates to securities, namely layered securities for the manufacture of banknotes, passports, shares, cheques, etc.

A large number of printed documents requires a highly reliable means of ensuring their identity due to the fact that these documents associated value. These documents are different from banknotes to securities giving the right of ownership, and include the signed documents, shares, cheques and passports. For this paper can match the value for their owner, the funds used for their identification must be quickly and easily seen. Moreover, to ensure that the public can rely on the authenticity of such documents, these funds should be permanent, long-term actions and difficult faked. This last quality is especially important to keep so that at least people no attempt was made by the knot, passports, checks and other valuable documents are very important to the authenticity of the document, because at any time any person may become the owner or user of such a document. Thus, the creators of these valuable documents are often concerned to create a means by which people could verify the authenticity of the documents, because ultimately most deceive unsuspecting people.

In a historical perspective attempts to guarantee the identity of valuable documents focused on two aspects of these documents: (1) the paper used as the basis for the document, which experts usually referred to as "securities", and (2) some indication of the reliability or put in the paper itself, or added when the conversion of paper into the final document. Due to the important role of public trust when creating documents of use to the authenticity of such documents, and securities, and a sign of reliability must meet a number of stringent criteria related to their structure and practicality. Among the criteria for securities are physical and optical requirements. Requirements for signs of reliability include n is sterowanie the authenticity of the final document.

Physical requirements for securities, particularly securities that are used for the manufacture of banknotes, mostly more stringent than the requirements for other types of paper. However, of these requirements is the "base weight" or "gymnast" paper, which is usually expressed in grams per 1 m2or in pounds per foot of printed paper (516 pages). For most securities underlying the weight must be in a very narrow range in order to give the document a sufficient weight or feeling such, meet the owner, despite the fact that the document should be easy to fold and unfold. Closely connected with the base weight of the gauge or thickness of paper, which is expressed in fractions of millimeters or inches. It is important that the caliber of securities used in any particular application, functioned well when working with machines, such as automatic Bank cash machines and high-speed sorting machines, which inevitably will process the final document.

Strength and durability are the most important quality securities because they give the final document, the ability to withstand both correct and nepravilnosti the main longitudinal load which can withstand a piece of paper without breaking. Other options include tear resistance in wetted form, simply tear resistance, resistance to tear and durability when folded. Because banknotes inevitably repeatedly fold and unfold in the course of their turnover from paper, from which they are made, requires great strength and durability when folded. Usually paper for banknotes produced in such a way as to allow approximately 5,000 - 8,000 collapse during the turnover of the banknote. It should be noted that the ratings of the securities, based on how much of the collapse of the paper can withstand not pervasis, can vary within a wide range depending on the applied test procedures. Moreover, modern banknotes, except that they should allow a significant number of bends should still maintain a certain degree of stability or resistance to bending, which is sometimes called the "christinam", so that they could pass through an automatic Bank cash machines and high-speed sorting device.

Among other important qualities securities include their porosity, the ability with the ability to absorb impurities, basically desired relatively low porosity securities to increase the likelihood that the document will retain a neat appearance during the period of its use. At the same time, securities require the characteristics of a good save printing to ensure accurate and specific seal used in the manufacture of the final document, as well as to ensure proper penetration and adhesion of the ink used in the production of documents. The printing processes used in obtaining themselves valuable documents, can produce extraordinary requirements for the paper. For example, deep or engraving print, often used in the printing of banknotes and other documents, assumes the existence of huge pressure between plate and paper. Selected paper must be able to withstand this pressure without loss of physical integrity. Finally, the dimensional stability of the paper during the manufacturing process and during the lifetime of the final document. In particular, the paper should not swell or shrink excessively because of the humidity, which is usually present during the manufacturing process and during normal use.

Securities usually p is th. The most important of these qualities is characteristic of the surface of the paper and its opacity. The surface characteristics include color, brightness, gloss, finish and smoothness. These parameters are usually specified by the designer of the final document on the basis of aesthetic qualities required from a document. To achieve the desired look and feel you require different processes, such as coating and calendarevent (polishing). The opacity of the paper is linked to the relative inability of light to penetrate through the paper. Opacity is usually expressed in percent of the light falling on one side of the paper, which is to monitor, on the other hand, does not pass through the paper, but is reflected or absorbed by the paper. For securities is usually desirable high opacity, i.e. exceeds approximately 75%. However, change the opacity on the fact can serve as an indication of the reliability of the final document, as in the case of watermarking, when the image of the sign, visible in transmitted light, is formed so that the paper takes the levels of opacity thus, to determine identifiable mark.

Selection and definition of the characteristics of reliability, the consist as it will be used. For this there are a number of reasons. First of all a sign of reliability is often a sign of the quality of the paper, for example, in the form of a watermark or special part of the paper. Even in the case when the topic is on the visibility to be an element separate from the paper, such features are often incorporated into the paper during its manufacture. This applies to a large number of characteristics of reliability, including the so-called "hairs reliability", chemical additives, colored confetti or thin ribbon, containing micro or other designations. In addition, even imposed on the surface characteristics must be compatible with the paper on which they are imposed, to create the desired adhesion and durability of the final document. Such imposed on the surface characteristics of reliability include nereproduguye image, such as artificially made lines that when photocopies, when applying the photosensitive coating and decamerone produce a shimmering figure. Even sophisticated artificial pattern printed on the surface of the document may be a sign of reliability, because it is difficult to copy. But in any case, the sign of reliability should be well-functioning the be. Such signs are difficult to copy to scare off potential falsifiers or at least with the intention that the documents were not achieved to the public. These characteristics should allow easy determination on the part of the holders or owners of the final document. In respect of banknotes and other documents, the authenticity of which usually relies on the audience, the signs should be different and scanned in normal light conditions. Finally, in certain cases it may be desirable that the characteristics of reliability could help determine the movement of large quantities of documents, for example banknotes.

Although these criteria may seem simple, the development of signs of reliability that reliably respond to them, not an easy task.

Historically, the production of an effective sign of reliability for documents based on specialized knowledge or skills possessed by only a very few people. Thus, for centuries, the rare talents of a master engraver and specialized knowledge of the printer was enough to prevent or discourage any attempts at tampering. Later a combination of specialized values from multiple DF teams of counterfeiters. However, modern advances in technology, colour Photocopying, scanning, printing and offset printing has made it possible to produce very convincing fakes even without such specialized knowledge. In order to be truly effective against fakes, signs of reliability should now be not only difficult replicable because of the specialized knowledge required for their production or due to a combination of specialized scientific disciplines embodied in one document, but they should be very difficult or impossible to copy on the most difficult photocopy machines.

Finally, in order to be suitable for the production of valuable by themselves documents, securities and an indication of reliability included in the paper or deposited, shall be jointly capable of conversion into an aesthetically pleasing document, with commercial speeds and with relatively low costs. Governmental, quasi-governmental and corporate structures that normally produce such documents require the least that their documents reflected the character producing their organization and taught to his greatest confidence as his funktsionalnostej a greater degree of freedom in the design and execution of the final document.

In the past, been proposed a number of approaches collateral securities effective sign of trustworthiness. Many of the proposed securities include signs of reliability during the paper production process, i.e. on the paper machine during the formation of the roll of securities. These types of paper are the signs of safety as watermarks, veins reliability, tape reliability with the microtext and without, confetti and other images included in the paper to complete the manufacture of paper. However, such securities generally cannot provide an indication of reliability, covering the entire surface of the securities, because of the need to drain the paper from moisture during final processing. In addition, such signs of safety as confetti, usually not localized within securities, as required by many of its applications. Although the features of reliability, as the ribbon and veinlets reliability can be localized in the paper, these images can cause difficulties when printing, cutting sheets and in other stages of the process due to high local paper thickness arising due to their presence.

Previously it was proposed that the product of molded boom is the super thick sheets of paper on each side of the synthetic substrate, include machine readable marks on the substrate material. These signs, such as universal product codes printed ink, which does not allow the passage of light with wavelengths nearest infrared radiation. Other characters are printed on the substrate and the printing inks, which transmits infrared light. The resulting marks are indistinguishable in visible light, but can be distinguished and read, if the cards of this paper to pass between a light-emitting diode with the desired wavelength and a photodetector. However, as described cards are not intended, and is unsuitable for use as securities because of their rigidity and low resistance to bend, which will inevitably be a consequence of their physical structure. In addition, as described in this document, the indication of reliability is not easy for various owner under normal lighting. On the contrary, the characters printed on the substrate, cannot be seen in visible light and, thus, they are not suitable for the average owner, without special detection equipment.

Another approach is the inclusion of the trait reliability in securities consists in forming the finished sheets of paper for education com the sheet molded with the formation of the securities in layers which included a pointer to its authenticity. Index of authenticity is printed on the inner surface of at least one of the sheets of paper to be formed and detected in transmitted light, but not in the reflected light. However, the printing of the signs of authenticity from one of the sheets of paper may cause problems associated with the "manifestation" or seepage of ink used to print the signs of authenticity, through the sheets of paper to the surface of the securities. Moreover, if the printing is applied on the thin inner sheet of paper, it usually involves the use of thin printing ink ("ink") that leads to a significant masking indication of the reliability of the surface seal and to the fact that the sign of reliability becomes less visible or completely invisible. In addition, the use of paper sheets in a layered structure does not lead to the fact that composite securities would have physical properties that exceed those that can be achieved in the case of more traditional odnorodnoi paper. In particular, the quality associated with life in circulation, including resistance to bend and tensile strength, in no way improved in the resulting layered structure.

In accordance with one aspect of the invention there is valuable paper containing the first and second sheets of paper and indicate which basically indistinguishable when viewed in reflected light and visible through the sheets of paper when viewed in transmitted light within the boundaries of the visible spectrum. In securities entered resinous sheet substrate having two surfaces, one of Cotai resinous sheet substrate, and the second sheet of paper is continuously formed on the other of the surfaces of the resin sheet substrate. Sheets of paper can be continuously formed on each surface of the resin sheet substrate by adhesive.

In accordance with another aspect of the invention includes a molded valuable paper containing the first layer of paper, a layer of colored symbols and a second layer of paper. In a molded securities entered resinous sheet substrate having first and second surfaces, and a layer of colored symbols located on the first surface layer of the substrate, and these color designations include at least one phase, the color of which corresponds to the light wavelength from 380 to 720 nanometers, while in securities entered in the first and second layers of adhesive and the first adhesive layer positioned on the first surface layer of the substrate on the specified layer of colored symbols, the second adhesive layer placed on the second surface layer of the substrate, the first layer of paper is placed over the first layer of adhesive and permanently attached to the layer of the substrate and a layer of colored symbols through the first layer of adhesive and the second layer of paper is placed over the second layer of adhesive and permanently attached to the layer polozcnych document containing the first and second sheets of paper, each of which has inner and outer surface. Valuable document has a resinous sheet substrate having two surfaces placed on one of these symbols, with each of the sheets of paper are continuously formed on a corresponding surface of the resin sheet substrate through an adhesive placed between the corresponding surface of the sheet substrate and the inner surface of each of the sheets of paper, and on at least one of the outer surfaces of sheets of paper printed a set of designations made interoperable with symbols on a sheet substrate with the formation of a complete image when viewed in transmitted light.

In accordance with another aspect of the invention includes a method of manufacturing securities, including defining a graphic pattern (design), printing this graphic picture as mostly transparent image and forming two sheets of paper. The method consists in the fact that determine a graphical illustration in color, print this graphic on the resin sheet substrate as mostly transparent color and the A.

In Fig. 1 shows a partial vertical section of a molded securities in accordance with the invention, showing the various layers of the layered structure and their interaction in transmitted light; Fig. 2 is a partial vertical section of a molded securities in accordance with this invention, showing the reflection, absorption and propagation of light falling on the paper surface of Fig. 3 is a perspective view of the banknote containing securities in accordance with the invention, with parts of the paper removed to show some of the possible interactive effects between the symbols on the various sheets or layers of paper; Fig. 4 is a perspective view of the banknote containing valuable paper according to the invention, with parts of the paper removed to show additional possible interaction effects between the symbols.

Although the invention permits of various modifications and alternative forms, the drawings are shown as examples of specific embodiments, which are discussed in detail and will be described. However, it should be understood that this invention is not intended to be limited to specific described species. On the contrary, the invention should include all modificati is ormula invention.

In Fig.1 shows a molded valuable paper 10 in partial vertical section to show the layers of which it is composed. Securities 10 ultimately intended for inclusion in the final document 11, for example a banknote, share certificate, cheque, passport or any other valuable in itself a document, which is desirable for ensuring the authenticity signs. It should be noted that valuable paper 10 may also find application in other areas, including letterhead, paper for special invitations, etc. Securities 10 includes a first sheet 12, the sheet substrate 14 and the second sheet of paper 16. Denote, collectively denoted by reference numeral 18, are located on one surface of the backing sheet 14 prior to forming the three sheets 12, 14, 16. Set notation 20, 22 may be located on the external surfaces 24, 26 either or both of the sheets of paper 12, 16, as shown in Fig. 1. Although throughout the description and in the claims refer 18, 20, 22 are referred to in the plural, it should be understood that the symbols 18, 20, 22 may be a single symbol or image on the sheet of substrate 14 or on any of the paper sheets 12, 16.

As will be more fully described below, spoon 14 thus, to register and interact with some set or all sets of symbols 20, 22 on the paper sheets 12, 16 with the formation of the "full image", for example, color images, when considered in transmitted light.

Preferably, the sheet substrate 14 was thin transparent resinous sheet material. As the sheet substrate 14 can be used on synthetic materials such as polyester or polypropylene, or organic resinous materials, such as cellophane. At the present time sheet substrate mainly preferred material of polyester film such as polyester film, manufactured by the firm of E. I. Du Pont de Nemours and commercially sold under the trade name Mylar. Preferably, the sheet substrate 14 had a basis weight of 11.0 - 22,5 g per 1 m2inclusive, and the thickness or gauge 8 to 16 μm. For the best working characteristics as in the course of further operations transformation, and for use after inclusion in the composition of the molded securities 10, it is desirable that the sheet substrate had a good geometric (dimensional) stability of the order of 1.5% (150oC 30 min). Information about the geometric stability obammunism comes in several types, including rolls, different manufacturers, including E. I. Du Pont de Nemours and Company, Imperial Chamical Industries Plc, Eastman Kodak Company and 3M.

Paper sheets 12, 16, included in securities 10, preferably of thin paper with high opacity. Preferably, the basis weight or gramnesty" sheets of paper ranged from 19 to 50 g per 1 m2inclusive, with the currently preferred "gymnast" about 34 g per 1 m2. Preferably, the thickness of the sheets 12, 16 were in the range of 0.038 - 0,050 mm inclusive. Usually the paper sheets 12, 16 may include fibrous raw materials, for example cotton, flax, hemp and wood fibre or a mixture of such fibers and cellulosic materials, such as wood pulp. Currently, the preferred composition of the paper, which is a combination of 75% cotton textile fibers and 25% wood pulp. However, it should be understood that this valuable paper 10 is not limited to any particular composition of the paper sheets 12, 16 and in specific applications, the exact composition of the paper sheets 12, 16 can be determined by persons producing the final document 11. In such cases, the paper sheets 12, 16 may include additional submit the NOC, and certain chemical additives that do not significantly affect the operation data color marks as a sign of trustworthiness. Preferably, the opacity of the paper sheets 12, 16 was at least 75%, and the degree of opacity in the range of 75 - 85% of such sheets gives good results when they are included in a molded securities 10. To obtain such a level of opacity in very thin paper, it is appropriate to process the transaction paper production add fillers and pigments. As a pigment it is convenient to use titanium dioxide together with a number of other substances, for example with calcium carbonate.

One such filler of titanium dioxide is commercially manufactured by the canadian firm Kronos under the trade name "Titanox RA 50.

The paper sheets 12, 16 can be manufactured by any suitable process of paper production. Although for receiving the paper sheets 12, 16 usually prefer machine Furdrine because of their ability to produce high-quality paper, you can apply and machines of other types, for example a cylindrical machine. To obtain good strength when wet during the process of paper production, it is preferable to add the resin Ho is manufactured by American Cyanamid Company and sold under the trade name "Parez" resin 607 and 613, or resin, supplied by Hercules Inc., under the trade name Kymene," such as Kymene 450" .

When the symbols 18 of the substrate is printed on the sheet substrate 14 as described in more detail below, the paper sheets 12, 16 are formed on each side of a sheet of substrate 14. In order to form the paper sheets 12, 16 to the sheet substrate 14 between the surfaces of the sheet substrate 14 and the inner surface of sheets of paper 12,16 be imposed by a suitable adhesive and leaves 12,14,16 are pressed into the molding machine, where the adhesive is cured, as described below.

Good adhesion of the paper sheets 12, 16 to the sheet substrate 14 is important for the efficiency of securities 10 in preventing attempts to copy it. Specifically, molded securities 10 should not be subject to delamination, which could open symbols 18 of the substrate up. You can use any suitable adhesive which, when cured in a layered structure to prevent delamination securities 10.

The adhesive may be one-component adhesive or glue, consisting of two or more components. You can also use adhesives, a vulcanized in the ultraviolet or e-beam. As is Elista by adhesive, preferably, the adhesive is transparent.

The particular adhesive used must be compatible with the substrate and with the paper sheets used in securities 10. Usually manufacturers of adhesives can provide this type of information about compatibility and suitability. Depending on the specific type of use of the adhesive may be imposed either on the paper sheets 12, 16, or on the surface of the sheet substrate 14, and the paper sheets 12, 16, and the sheet substrate 14. Usually prefer adhesives based on polyurethane, and are successfully using the adhesive supplied by the company Imperial Chemical Industries Pls from the UK and sold under the trade name "Novacote ADH 222". The degree of coverage of the adhesive should preferably be in the range from 1.5 to 3.0 per 1 m2however , the levels of consumption can vary depending on the type of adhesive.

Preferably, the symbols 18 of the substrate is deposited on the sheet substrate 14 by the seal. This purpose is prepared graphic symbols 18 in accordance with any motivic image that it is desirable to have at the end a valuable document 11. These designations 18 often contain the image, as shown in Fig. 3 and contain black-and-white signs, or to include the full range of visible colors can cover the entire surface of the sheet substrate 14, or may apply only to certain areas. If the designation of 18 on the sheet substrate 14 are designed to interact with a set of symbols 20, 22 on any of the sheets of paper 12, 16, to determine the signs of the substrate usually prefer transparent inks. As will be described in more detail below, the use of transparent inks allows the observer rassmatrivaya securities 10 or the final document 11 in transmitted light, to perceive the full image, created by the interaction of the transparent color designations 18 on the sheet substrate 14 and the set notation 20, 22 on the sheet of paper 12, 16.

The designation of the substrate can include a layer of white or opaque inks on or/and under the transparent color designation. Preferably these white layers on both sides of the transparent colored paint. These white layers serve two functions. First, they increase the opacity of the securities 10, at the same time allowing you to see the symbols 18 of the substrate in transmitted light. Secondly, these layers create an additional sign of reliability in the case when the value of paper 10 rassart forgers, trying to copy the symbols 18 of the substrate, the white layers are not allow to reproduce the color designations. Any further attempts to access a color notation by removing the white layer will lead to the destruction of colored symbols that will frustrate all efforts to make the fake.

An important aspect of this securities 10 is its ability to allow you to control its authenticity by any owner under normal lighting. Because the visible spectral range of the person corresponds to wavelengths of light from about 380 to 720 nm, the ink used for the symbols 18 of the substrate, it is preferably colored transparent inks whose colors correspond to wavelengths within this range.

In a valuable paper you can reach other optical effects by printing some or all of the symbols 18 with fluorescent or phosphorescent inks, such as inks, visible only under ultraviolet light. If education is part of the legend of the substrate used UV paint, signs, printed with such inks may be in principle not recognized in normal conditions, but visible in ultrafiltration use opaque paints, such as opaque white ink, or by plating, for example by deposition of metal from the vapor phase on the surface of the sheet substrate 14. Using the last method is especially suitable in the formation of microtext as part of the designation 18, clearly visible on securities only in strong transmitted light, but in principle indistinguishable in the light reflected. Finally, denote 18 can include parcels, printed magnetic ink, which serves a dual purpose: it forms part of the full image, visible in transmitted light, and creates an additional sign of reliability, the detected magnetic-sensitive detector, the type of which is well known in the art. The design of the symbols 18 of the substrate securities 10 allows a greater degree of flexibility to the pattern characteristic of reliability that should be included in the final document 11 due to the complete image, which was mentioned above. For instance, 18 may represent a region resembling a watermark in the final document, but in any visible color or any combination of colours. Alternatively, the color designations of 18 can add colorful details to set notation 20, 22, imataka cases, at least part of the surface of symbols or characters 20, 22 you can also print transparent printing inks. As will be described in more detail below, when using transparent paints for surface signs 20, 22, and signs 18 on the substrate will dominate in the full image when observed in strong transmitted light, whereas only the color of the surface designations 20, 22 will be visible when the final document 11 is viewed in reflected light. This happens even if the opaque layers are located next to the colored areas, as already mentioned. Plots of surface designations 20, 22 can be in principle invisible when observed in transmitted light due to the dominance of the symbols 18 of the substrate. Similarly the symbols 18 of the substrate created by colored printing inks can create a colored background, such as a rainbow or color company logo, on which is printed on the surface of the designations 20, 22 appear when observed in transmitted light. For example, the surface designation can be lines or printed words, such as the name of the company, and they do not necessarily have to cover designations 18 on the substrate. As will become apparent in the course of further discussion, though, about imagestate with surface marks 20, 22 on any of the sheets of paper 12, 16, or two sheets of paper.

In Fig. 1 and 2 more shows different layers securities 10 modes of the reflected and transmitted light. As shown in Fig. 1 and 2, a molded securities 10 includes a substrate layer 14, the layer designations 18, is placed on one surface of the layer of the substrate 14, the first layer of paper 12, is permanently fixed above the layer with the notation 18, and a second layer of paper 18, is permanently fixed on the other surface layer of the substrate 14. Layers of adhesive 28, 30 serve to link layer of the substrate 14 with the paper layers 12, 16. As mentioned above, the final document 11, including securities 10 has a surface designation 20, 22, printed on the outside surface 24, 26 of each of the paper layers 12, 16, or to both layers.

Light, for example white, including components of wavelengths of approximately 380 to 720 nm, incident on security paper 10, or passes through the paper, absorbed it, or reflected. As shown by line 32 in Fig. 2, passing the light passes through all layers securities 10 and emerges from the surface 24 of the paper opposite the surface 26 through which the light entered. The absorbed light, however, is scattered and absorbed Volovec, presented on Fig. 2 line 36, does not penetrate into valuable paper 10, and the rebound bounces from the surface 26 of the paper and any designations 22 placed on the surface 26.

As shown in Fig. 2 in respect of securities 10 observer located on the same side of the paper as the light source (not shown), which may extend the lines 32, 34, 36, perceives only the reflected light 36, while the observer on the opposite side securities 10 sees past the light 32 from the light source. Since the absorbed light 34 effectively "captured" in the layers securities 10, it is not perceived by any of the observers. Due to the high opacity of the layers 12, 16 of this securities 10 virtually all of the light penetrating the valuable paper 10, passes through the layers securities 10 or absorbed by the paper layers 12, 16. Since almost no light is reflected from the symbols 18 on the substrate, the labels 18 are practically not perceived by an observer, learning valuable paper 10 in the reflected light, and cannot photographic reproduction of surface symbols 18 of the quality that you want to forgers.

Interaction designations surfaces 20, 22 kotoroe the amount of light 38, falling on security paper 10, penetrates into the paper through the surface 26 and passes through the surface layer 16, adhesive layer 30 and the substrate layer 14, falling to denote the substrate 18. The sections 40, 42, 44, 46, 48 transparent light signs substrate 18, the color of which preferably matches the colors of the visible spectrum having a wavelength of approximately 380 - 720 nm, absorb certain frequencies of the transmitted light depending on the color transparent ink superimposed on this plot, and miss the rest of the world. Then this ozvuchenny light shown in Fig. 1 shaded areas, passes through the layers of adhesive 28, the paper 12, and exits the surface 24 securities 10.

If the surface designation 20 do not contain transparent color designations, the light emerging from securities 10 has basically the same color as the sections 40, 42, 44, 46, 48 symbols 18 of the substrate through which the light passed. In regions of the surface designations 20, is covered with a transparent colored printing inks, the color of the transmitted light emerging from the paper, basically the same areas of the substrate under these sections. The total image is observed and leaving securities 10 in the festival is located on the surface. The stronger the light passing 38 incident on security paper 10, the more the image created by the designations 18 on the substrate, will dominate over the whole image, created by the signs on the surface. In Fig. 1 also shows how other optical effects can be included in a security paper 10. Instead of a transparent printing ink notation 18 on the substrate may contain sections 54, which are made opaque by metallization or by printing an opaque ink. Of course these areas 54 will effectively stop all passing light and thereby create dark areas in full of the perceived image. Alternatively, substrate 14 can be perforated in some areas 56. This perforation is filled with adhesive during forming different layers securities 10. Because the adhesive is preferably transparent, such perforated sections 56 will transmit light without changing its composition.

Examples of such interaction effects are shown in Fig. 3 and 4. In Fig. 3 line, in which figure 1, is surrounded by a circle (shown by the dotted line), shown in such a way that it could be printed in the lower corner of the outer surface and 26. Coloured areas 62 (only one such plot is shown in Fig. 3) on the sheet substrate 14 are arranged in such a way as to accurately adjust (register) to the number in a circle on the paper surface 26 and be over it. In this embodiment, the observer, viewing the outer surface 26 of the final document 11 in the reflected light, will perceive only located on the surface of designations 22, 60. When the same document 11 is inspected with the same hand, but the light source is on the opposite side of the document relative to the observer, the full image perceived by the observer, will include a line 60, ozvuchennoy colored patches 62 on the substrate.

A similar arrangement is shown in Fig. 3 for the labels 18 on the substrate, depicting the building and the landscape 64. Image 66 printed on the outer surface 24 of the sheet of paper 12, may include lines and transparent inks, covering some portion of the surface or the entire surface of the image 64. As in the previous example, the observer, considering the document 11 in the reflected light, will perceive only the image 66 as it appears on the surface 24 of the sheet of paper the children to perceive the full image, created surface image 66 in combination with the image on the substrate 64. In General, the greater the intensity of the light used to view the document 11 in transmitted light, the more the image on the substrate 64 will dominate in the full image perceived by the observer. If necessary, refer on the surface can even be in principle invisible when the document is viewed in proishodjaschem light due to the dominance of the image on the substrate 64 in the full image.

Another example of interaction effects signs 18 on the substrate and surface designations 20, 22 shown in Fig. 4. As mentioned above, the design and placement of signs 18 on the substrate need not be of identical design and placement of surface designations 20, 22.

As shown in Fig.4, the characteristic of reliability, included in securities 10 may consist of a "shadow" effect produced by the designations 68 on the substrate when seen in transmitted light. In such cases, the surface designation 20, 22 need not include lines or other designations, specifically "otoczenie" marks 18 on the substrate in the full image is to be placed 18 on the substrate form a complete image in combination with the marks on the surface 20, 22 posted on securities 10 in the final document 11, the process of manufacturing securities 10 in the General case begins with a graphic design of all symbols 18, 20, 22, which must be printed on the sheet substrate 14 and the paper sheets 12, 16. Alternatively, a graphical design notation 18 on the substrate can be prepared regardless of the surface designations 20, 22, especially if the one who produces the paper uses standard paper for a number of different target documents. In any case, graphic symbols 18 on the substrate can podgotovyatsya designer on the basis of any color picture or motif, and may include the full range of visible colors and details. When designing a graphic designer can specify that the image should be placed on securities 10 or continuously, or with repetitions printed on the substrate 14. As described above, the graphic design for the labels 18 on the substrate may include colored areas, which in the final document 11 will be printed surface designations 20, 22, including text.

In addition to color characters and images, a graphic designer may include in the designation 18 on p and transparent white ink, and the instructions printed fluorescence, fluorescence or magnetic paints. Moreover, the picture may contain perforations made in the sheet substrate 14 and designed to pass light passing without changing it. In the figure can also be metallized areas to make the sheet substrate 14 is opaque.

The graph is processed to convert it into manageable print. Preferably this is achieved by an electronic color separation. Known a number of suitable devices for the separation of colors, including laser analyzers and scanners. These devices convert the image into image elements or a matrix of tiny dots, containing the basic or primary colors. Device for separating colors determine the color intensity of the picture elements and encode and remember the analyzed image.

When color separation is completed, prepared printing plates or cylinders for printing signs 18 on the substrate on the surface of the sheet substrate 14. The preferred printing process is playing with Rotogravure. Electronic device for separating colors of the support of the photosensitive material in the indirect process of chemical engraving Rotogravure cylinder. Synthesis of colors in the printed designations 18 on the substrate is performed by a separate Rotogravure cylinders for each transparent color for each opaque or magnetic printing ink used in the graphical illustration. The depth of the engraving Rotogravure cylinder is typically in the range 3 - 32 ám.

Preferably, before the printing of the symbols 18 of the substrate sheet on the substrate sheet 14, the substrate to be processed by corona discharge to improve adherence of the ink sheet substrate 14. It was also found that treatment with corona discharge increases the adhesion of the paper sheets 12, 16, which are formed on the sheet substrate 14 later in the manufacturing process. This treatment by corona discharge can be carried out in any suitable apparatus, readily available commercially for processing films, for example in the apparatus for processing manufactured by Sherman treaters are North America Inc.

If desired, the sheet substrate 14 may be metallized or perforated to print, if it is determined graphical drawing of the symbols 18 of the substrate. For the metallization process, the preferred method is formirovanie sheet substrate 14 can be used for the formation of microtext, specific drawings or dotted contours to create additional sign of reliability. This perforation is usually made on special perforating machines having a needle diameter is usually from 0.8 to 1.0 mm, which pierce the sheet substrate 14. If the perforated pattern must interact with printed or metallic area on the sheet substrate 14, it is preferable that the step of punching was carried out after the completion of the stages of printing and plating. This perforation can be performed on any suitable machine, such as machines, commercially supplied by the firm Zimmermann & Co.from Berlin, Germany.

Then the sheet substrate 14 is imprinted designations 18 of the substrate, and between the stages of printing passes enough time for printing ink could dry. For printing, as for other stages in the preparation of securities 10, preferably of sheet substrate 14 was drilled from a roll resinous film or foil. Processing the substrate material in the form of a roll facilitates stages of printing and molding and allows the process suitable for production quantities of the product and with umerei 12, 16 to obtain securities 10, in this preferred device for moulding securities 10 forming is carried out at a molding station, comprising molding machine of well-known type and section vulcanization adhesive tunnel type. Such molding machines commercially supplied by a number of manufacturers, for example, the firm Cerruti from Italy. To form a layered structure, two sheets of thin paper with high opacity served in the molding station preferably from continuous rolls, and printed sheet substrate 14 is fed into the station between sheets of paper. The adhesive is continuously applied to either surface of the sheet substrate or on the surface of the paper facing sheet to the substrate, depending on the type of adhesive and the sheets are pressed intermediate calender rolls to obtain a layered structure. The layered structure passes through the section of vulcanization, where the adhesive is cured to permanently associate molded layers. Specific design section vulcanization depends on the type of adhesive used and the conditions of vulcanization, the manufacturer's recommended adhesive.

Securities, emerging from fourmeau is to cut the sheet during its manufacture. For this you can use any suitable device for cutting sheets, for example the cutter Pasaban. The format to be installed on the cutter, depends on the technical conditions to be determined by the end user securities 10, and ultimately the size of the document, which must be made of the securities.

After cutting the sheets you can perform counting and quality control and surface designations 20, 22 can be printed on one or both sides securities 10. Valuable paper 10 is suitable for gravure printing, which is generally preferred for documents, such as banknotes, as well as for multicolor offset printing. If you want a combination between the symbols 18 of the substrate and surface marks 20, 22, it is preferable that the signs match was included in the symbols 18 of the substrate. Printing on valuable paper 10 is exposed to the register basically the same way as for known watermark.

As was found, the above method allows to obtain high-quality securities with physical and optical properties were largely consistent with those that have known securities, or superior to them. Symbols 18 in the world and is clearly seen when considering in transmitted light. The stability of the colors forming the symbols 18 of the substrate is very high, especially if you print these symbols 18 are used pigments similar to those used for the manufacture of Bank notes and other valuable documents.

Since the designation of 18 printed on a sheet substrate 14, and 18 denote the substrate is separated from the paper sheets 12, 16 layers of adhesive 28, 30 in a molded valuable paper 10, it avoids the "manifestation" of the symbols 18 of the substrate. In addition, the speed with which you can obtain this valuable paper, exceeds the rate of production, normal to receive securities with watermarks.

Valuable paper 10 provides a number of additional characteristics of reliability in comparison with the known securities. Due to practical difficulties printing on thin resinous film and produce very fine papers with high opacity, only very few people will have the knowledge and machinery required for copying securities. In addition, the inability of fotosprivadas denote substrate 18 effectively prevents duplication by Photocopying. On the other hand, the full image, vosprinimaemogo spectrum creates a simple and effective means by which the owner can verify the authenticity of the document in normal lighting.

Securities in accordance with the above description was prepared and tested. The results of these tests are briefly summarized in the following four examples in the table, together with the results of similar tests are commercially supplied securities.
