The invention relates to a data carrier, in particular a valuable document, for example a banknote, identification card or similar storage media having lot with hallmark, and to a method of manufacturing such media.

In order to protect the media, for example, protective, securities or identification documents, as well as other precious objects, often provide protections that allow you to check the authenticity of the medium and at the same time providing protection from unauthorized reproduction. Currently, increasingly transparent protective means, such as a transparent window in the notes. To obtain such a window, for example, on the banknote, in which you previously completed a through hole, place the specified closing the opening film, one side of which has the adhesive layer.

Based on the foregoing, the object of the present invention is a further improvement of the media of the specified type from the point of view of their appearance and protection from unauthorized reproduction.

The problem is solved by offering media and manufacturing method characterized by the features stated in the independent claims. Options offer aemula of the invention are reflected in the dependent claims.

In accordance with the invention, the original data carrier, in particular a valuable document, such as a banknote, identification card or other similar document that contains a substrate having an area with a distinctive sign, formed by the family of curves consisting of a set of curved and/or diverging cut lines, and within this area with the hallmark put an identification mark in the form of patterns, characters or a code made by visual or machine recognition.

In this case, the curvature of the cut lines can be continuous, arcuate, decreasing or increasing along the cut lines, or undulating in the form of the wave profile. In the case of diverging straight cut lines, the distance between them is not constant, but rather increases, and the direction in which the distance is increased, in the context of the present invention is arbitrary. Curved cut line can be equidistant, may diverge or may be on different sites to get different.

Preferably, the identification mark is formed by a family consisting of a set of curved and/or diverging cut lines so that the cut line identification sign form the first cut line and cut the line plot with the hallmark, beyond identification sign, form a second cut line, and first and second cut lines that adjoin each other, the different width of the slots. Because of the different widths of the grooves in the first and second cut lines and the resulting varying degrees of coverage area inside the surrounding transparent area identification sign be visually perceptible in transmitted and/or reflected light, or if it is covered with an opaque layer, its detection is possible by a machine.

In this case, the width of the first cut lines may be more or less than the width of the second cut lines. Wide cut line at least 10%, 20%, 50%, and even more than 100% wider than the narrower slotted line. In preferred variants of the invention, the width of the first and second cut lines is essentially constant in each case. The phrase "essentially constant" indicates that, in practice, laser cutting, even with the same settings, maybe a small change in width and, thus, it will not be quite constant.

In a preferred embodiment of the invention at the site with the hallmark of the substrate is provided with a label substance modified under the influence of laser irradiation is of, and at least cut the line with the hallmark outside of the identification mark, have a regional area, modifiable under the action of laser radiation. If the cut lines exist within an identification sign, they usually also have a regional area, changing under the action of laser radiation. In other embodiments of the invention, the area identification mark has no slits, she just specially equipped with marking lines or marking contours, as explained below. The substrate can be specially equipped with a marking substance that changes color under the influence of laser radiation. In this case, the cut line on the plot with the hallmark outside of the identification mark, and cut lines on the inside of the identification mark, if any, have colored edge areas.

Alternative or additionally, the substrate can be provided with a marking substance having the properties of absorption of infrared radiation, magnetic, electric or fluorescent properties, changing under the action of laser radiation. In this case, cut the line plot with the hallmark outside of the identification mark and incised lines the inside of the identification mark, if any, have edge areas with the changing characteristics of the absorption of infrared light, magnetic, electric or fluorescent properties compared to the surrounding areas. These implementation options allow you to perform simple additional automatic authentication plot with hallmark. Of course, it is possible, in accordance with which authentication can be performed with the naked eye or using a simple additional means, for example, ultraviolet lamp.

Preferably, as the marking substance is possible using a modified laser dyes. Dyes with different properties, in particular with respect to their primary color, the color change under the influence of laser radiation, the energy threshold and the desired laser wavelength known to the person skilled in the art. Specialists also known dyes with such effect that changes under the action of laser radiation not only color, but also the characteristics of the absorption of infrared radiation, magnetic, electric or fluorescent properties. Changing the properties of the dyes is possible under the action of laser radiation of ultraviolet, visible or infrared spectral what about the range, for example, under the action of radiation of CO2laser with a wavelength of 10.6 microns.

In accordance with another, preferred, embodiment of the present invention use a modified laser marking substance that does not contain dyes. May also be applied to the substrate or enter the inside of the substrate not containing coloring substances, for example, gravure printing or printing inks. When using do not contain dyes marking materials can produce a coating with high transparency, which under the action of the laser is injected with high speed constant and high contrast identification mark. You can change that does not contain dyes marking substances under the action of laser radiation of ultraviolet, visible or infrared spectral ranges, for example, under the action of radiation of CO2laser at a wavelength of 10.6 µm. Specific non-limiting amount of the proposed invention examples of marking materials that do not contain dyes and modified under the action of laser radiation, described in the publications WO 02/101462 A1, US 4,343,885 and EP 0290750 B1. In particular, as the marking materials can be marked by the use of laser compositions described in the publication EP 1648969 B1, changing under the influence of the cutting sub> 2the laser.

In accordance with another preferred variant of the invention, the identification mark is formed by a section of the substrate without slots. Thus, the identification mark is visible on the background segment with hallmark, especially in transmitted light.

According to another preferred variant of the invention, the identification mark is formed by a section of the substrate without slots, containing a collection marking of curves with many marking lines connected with incised lines outside of the identification mark. In General, in the context of the present description, the term "marker line" always refers to not cut, but merely marked lines. We can also perform lines having inner slotted area and external marking area, such lines are called lines (color) edge or lines (color) edge.

In accordance with the specified variant of the invention, the identification mark is visible in transmitted light as part of the substrate without slots, and is clearly visible when observed from above due to the presence of the marking lines.

In this case, the substrate is applied marking material that changes color under the action of the laser is wow radiation, so marking line identification sign be colored. Alternative or additionally, the substrate can be provided with a marking material whose properties associated with the absorption of infrared radiation, as well as magnetic, electric or fluorescent properties change under the action of laser radiation so that the marking line identification sign will have a different characteristic absorption of infrared radiation or other magnetic, electrical and luminescent properties compared to the surrounding areas. As the marking materials can also apply any of the above substances.

By choosing the appropriate laser parameters it is possible to apply color marker line without additional marking substances, for example, in the firing process, when the fibers of the paper discolor, or when under the influence of the laser change the transparency of the polymeric substrate.

In accordance with another preferred variant of the invention, the identification mark is formed by a section of the substrate without slots containing many nested into each other marking contours with decreasing size. Here marking the contours properly follows the form of the identification mark, keeping the sun is the details of its external contour, when reducing the size of the circuit is not already played. In this embodiment, the identification mark with the drawn pattern is clearly visible in reflected light.

As in the previous embodiment of the invention, in this embodiment, a coating on a substrate marking substance with changing under the action of laser radiation color and/or changing the properties of absorption of infrared radiation, magnetic, electric or fluorescent properties so that the marking circuits are, respectively, the changing properties.

In all variants of implementation within the zone with the picture may be placed through the window with a picture in the form of patterns, characters or a code. In preferred embodiments of the invention, the shape of the window with the figure and shape of the identification mark have a semantic relationship. Such a semantic relation can be expressed in that window figure has the same pattern as the identification mark, with possible differences in their position in space and/or sizes of the two painted figures. The semantic relationship may lie in the fact that the first and the second depicts the drawings represent only part of the picture that complement each other to get the whole picture, or that depicts the first and second drawings complement the each other and form a complete associated image.

In all embodiments of the invention it is also possible execution of the plot with hallmark in the form of patterns, characters or a code, and possible semantic relation between the form of the plot, with the hallmark with the form of the identification mark and/or, if applicable, with the existing window with a picture. However, the shape of the plot, identification sign and window picture can be chosen in such a way that they were independent from each other and each of these elements formed the independent figure.

In accordance with another variant of the invention the plot with the hallmark contains in addition to the family of curves with many curved and/or diverging cut lines, also the family of the marking of curves with many marking lines, preferably a lot of curved and/or divergent marking lines. Perhaps the performance of slotted and marking lines going under arbitrary angles to each other. In this case, the identification mark is formed preferably the area of the substrate without slots containing two families marking of curves, each of which includes a set of marking lines and marking lines of one family connected with incised lines located outside of the identification mark, and marking the line of the other family connected with marking lines, located outside of the identification token.

In accordance with another preferred variant of the invention, the boundary identification mark has a marking circuit, in particular, color marking circuit to improve the readability of the identification mark in the reflected light.

In all variants of the invention, the width of the cut lines is from 0.05 mm to 1 mm, the Preferred distance between the centers of these lines ranges from 0.05 mm to 3 mm, in particular between 0.5 mm and 1.5 mm, the distance between the centers of the lines may be permanent (equidistant cut line) or variable (diverging cut lines). In the cut lines with boundary zones the preferred width of the marginal zone on each side is from 0.02 mm to 1 mm, and a simple marker line without zones with slots typically have a width of from 0.05 mm to 3 mm

In a preferred embodiment of the present invention a family of curves on the plot with the hallmark formed by many equidistant curved incised lines. In another preferred embodiment of the present invention a family of curves on the plot with the hallmark of established many direct diverging cut lines.

In accordance with one embodiment offer aemula of the invention, the relative location of the family cut lines and identification mark forming an additional sign of authenticity, in accordance with which different instances of the media choose different relative location of the family cut lines and an identification sign.

The plot with the hallmark of the recording medium can be enhanced element of the foil. In this case, the element of the foil may include a family of curves, creating together with the curves on the plot with the hallmark, the moire effect. For example, the distance from center to center family of curves on the element of the foil may be slightly different (for example, a few percent) of the distance from center to center in the family of curves on a plot hallmark, and/or the two families of curves can be slightly rotated (e.g., a few degrees) relative to each other.

However, you can also use plot with hallmark without an additional element of the foil, performs the functions of the protective element. The media, in particular, can be a protective element, a security paper or value document.

In one preferred embodiment of the present invention, the area with the hallmark forms a transparent area in which the appearance of the identification mark in the reflected and/or noise light is different from the appearance of other parts of the plot from ikitelli sign.

According to another preferred variant of the invention the plot with the hallmark of the cover on one or both sides of the information carrier layer with a low light transmittance so that the identification mark is not actually visible in reflected light, but is allocated only in transmitted light.

Finally, according to another preferred variant of the invention, the section with the hallmark of the cover on one or both sides of the media opaque layer so that the identification mark is not readable visually, but is readable by a machine, for example, using ultrasound.

The present invention also includes a method of manufacturing a data carrier of the type specified above. For this purpose, the substrate form the plot hallmark, by laser cutting put a family of curves consisting of a set of curved and/or diverging lines, and within the area with the hallmark perform identification mark made with visual or machine recognition, in the form of patterns, characters or a code.

Identification mark preferably form a family of curves with many curved and/or diverging the first cut lines made the e the cutting laser beam, as the second cut line on the plot with the hallmark outside of the identification mark, and the first and second cut lines perform different cutting width by changing the laser parameters, in particular, its capacity and/or cutting speed.

In accordance with a preferred variant of the invention the substrate at the site with the hallmark equipped with modified under the influence of laser marking substance, and cut the line, beyond identification sign, modify their edge zones by exposure to laser radiation. Thus, preferably under the action of laser radiation cut line lying inside identification sign, modify their edge zones by exposure to laser radiation.

In accordance with an additional preferred option identification mark is formed on the area of the substrate without slots, with identification mark preferably form a family marking of curves with many marking lines, made by the same laser beam that cut line located on the transparent area outside of the identification mark, with incised lines outside of the identification mark, and labelling cnie line identification sign performed by changing parameters of the laser, in particular, its capacity and/or cutting speed.

Below the invention is explained the example of the banknote. In figures 1 and 2 is shown schematically banknote 10, having a site with hallmark, made in accordance with the invention, in the form of a transparent part 12, shown in more detail in figure 2.

As shown in the top view in figure 2, the section 12 with the hallmark formed by a family of curves consisting of a set of direct diverging cut lines 22, which is made on the paper 20 banknotes by exposure to laser radiation. In the specified embodiment of the invention the width of the slits in the family of curves cut lines 22 is 0.15 mm, and the distance between the centers of the lines on the bottom edge of the transparent section 12 is equal to 0.4 mm, and at the top edge to 1.0 mm So that the cut lines cover from 15% to 37.5% of the plot, so transparent ucast the 12 visible on the top view, and, if you look through it.

Transparent region 12 made in the form of geometric shapes, such as oval, shown in figure 2. Its circuit is shown in figure boundary line 24, indicated by the dashed line, and is used simply for graphical illustrations of some form.

Inside the transparent part 12 placed identification plate 30 whose appearance in reflected and/or transmitted light differs from that of the surrounding transparent part 12, due to which this sign is perceived by the observer. Specified identification mark 30 is usually performed in the form of patterns, characters or a code; in this example embodiment of the invention it looks like a maple leaf. The circuit 34 identification plate 30, indicated by the dashed line, is used only for graphical illustrations of its shape and does not necessarily correspond to the real contour, available on the banknote.

In the embodiment of the invention shown in figure 2, the identification mark is also formed by a family of curves consisting of a set of direct diverging cut lines 32, connecting with exact alignment with the cut lines 22, beyond the identification mark on a transparent area 12. This cut line 32 inside identification plate 30 is made with a width of the slit of 0.3 mm, and thus the m significantly wider than the cut lines 22, outside of the identification mark. Because identification plate 30 covers the lower area of the paper, the figure "maple leaf"formed by this sign, depending on lighting conditions and background clearly visible in reflected and/or transmitted light.

The exact combination of cut lines 22, 32 of different widths is achieved through the execution of these lines are laser cut using the same laser beam in a single operation. The difference in width of the slots is achieved by changing the laser parameters, in particular, its capacity and/or speed of cut during the cutting process.

As an illustration, figure 3 (a) shows the normal spatial distribution of the power W of the cutting laser beam. At constant speeds and maximum power (distribution 40) the energy of laser radiation delivered to the paper exceeds the threshold required for cutting paper 20 in wide area 42 of the cutting. In contrast, when the distribution of 44 with a lower maximum power threshold energy required for cutting paper, is exceeded in a more narrow area 46 of the cutting, and the result is a smaller width of the slots. Thus, at a constant cutting speed due to the almost instantaneous change of the laser power, dostigao is required by changing the width of the slot, created by a laser beam, along a path of the laser beam.

Thus, as illustrated in figure 2 and detailed drawing presented in figure 3 (b), you can perform connected cut lines 22, 32 in a single operation, thus achieving the perfect combination of these lines. To do this, when switching from a transparent part 12 (cut line 22) in the area identification mark 30 (cut line 32) increase the laser power and thus the width of the slits, and the transition from the zone identification mark 30 (cut line 32) in the transparent area 12 (cut line 22) the laser power and, consequently, the width of the slits is again reduced. This is clearly shown in figure 3 (b), illustrating the transition from the wide cut lines 32, inside identification mark 30 (width 42 is equal to 0.3 mm), narrow cut lines outside of the identification mark (width 46 0.15 mm), occurring exactly on the border 34 of the identification plate 30.

Changing the width 42, 46 of the slots is also possible by changing the cutting speed at constant laser power. At high cutting speed of the laser radiation acts on the paper relatively short time so that the energy supplied to the paper, small. Accordingly, the threshold energy, the mu is necessary for cutting paper, will be exceeded when a high power laser only in a narrow zone of cutting. On the contrary, at low cutting speed of the laser radiation acts on a longer paper, so the paper gets more energy. Accordingly obtained over a wide area of cutting, which exceeded the threshold required for cutting paper. Also, to extend the range of available changes, possible joint and simultaneous change of both parameters of the laser power and cutting speed.

Figure 4 shows a variant embodiment of the invention, which has a transparent section 50 with the cut lines 52, beyond identification mark 54, and performed, as in figure 2, by laser cutting. Unlike the implementation shown in figure 2, the family of curves a transparent part 50 contains equidistant curved cut line 52. Also within the area identification mark 54 power cutting laser was installed below the threshold of cut paper 20, so that the area of the cut lines are missing. Thus, the identification mark 54 is not subjected to the cutting area of the paper and clearly perceived in the background section 50 with hallmark, especially in transmitted light.

Figure 5 shows another variant implementation of the invention, in the cat the rum has a transparent region 60 with a family of curves, containing cut lines outside of the identification mark 64, representing curved and diverging cut lines 62. In addition, figure 5 shows the optional marking of the external circuit 66 identification mark 64, made using laser radiation. For this purpose, as described in more detail below, the paper 20 banknote provided with a modified laser marking substance that changes color under the action of laser radiation. To create the external circuit 66 parameters of the laser is set so that the laser energy was below the threshold of cut paper across the diameter of the laser beam, but in the inner zone, it must be above the threshold for the reaction of modified laser marking substances, providing, thus, a color change.

Figure 6, similar to figure 3 (b), illustrated in detail a variant implementation of the invention in which the transparent area 70 and the identification mark 80 is formed by a lot of curved and/or diverging cut lines 72 and 82. Cut lines 72, 82 are connected with the exact combination on the border 86 identification mark, and the width of the cut lines 72 beyond the identification mark 80 is selected, as in the example embodiment of the invention in figure 2, less than the width of the slit lines 82 identification inside the Naka 80 through an appropriate change of parameters of the laser. In addition, each of the cut lines 82, inside identification mark and lines 72, beyond identification sign, both sides have exactly the combined colored edges 74 and 84.

To obtain such colored edges, just shared with incised lines, before carrying out laser cutting paper for 20 banknote cover in certain places of the alleged transparent part 70 modified by the laser material, for example, dyes that change color and delivers the desired color change when exposed to laser radiation, for example, from colorless to red.

The principle of joint run with the exact combination of cut lines 72, 82 and colored edges 74, 84 are explained in figure 7, which shows a graph 90 of the spatial distribution of power or energy of the cutting laser beam. In the inner zone (zone 92 cutting) laser energy exceeds the threshold energy E1 required for cutting paper 20. 7 the energy response of the current dye, above which occurs desired color change indicated by E2. From the graph it is evident that in the marginal zone of the laser beam, a marking zone 94, the laser energy is between the energy E2 reactions required for color change, and energy E1 required for cutting, so marcinowicz the Oh zone 94 is changing color of existing dyes without cutting the substrate.

Thus, the laser beam 90 cuts the paper 20 banknotes with dyes that change color under the influence of the laser, in the Central zone 72 or 82, the corresponding area 92 cutting, shown in Fig.7, and also changes the color of the paper in the marginal zones 74, 84, precisely aligned with the cut lines 72 and 82. Here the width of the color of the edge zones 74, 84 corresponds to the width of the marking zone 94 and depends on the parameters of the beam, energy of the reaction of existing dyes used for protection, and paper properties. Outside zone 92 cutting and marking zone 94, the laser energy below the threshold of response of these dyes, so the paper condition is not changed.

In order for the circuit identification label was better visible in reflected light, the outer contour of 66 identification mark 64 can be marked by means of laser radiation, as shown in figure 5. For this purpose, the parameters of the laser is set so that the laser energy was below the threshold of cut paper across the diameter of the laser beam, but in the inner zone it should still be above the threshold for the reaction of active dyes, which is achieved, for example, by setting the laser energy in the range between the values of E1 and E2, as shown in Fig.7.

On Fig shows another variant implementation of a transparent part 100 in accordance with the proposed izopet the tion, in which cut lines 102 outside of the identification badge 110 is made, as at 6, by means of laser cutting paper 20 banknotes, provided with a marking substance, together with colored edges 104. However, in contrast to the example embodiment of the invention, shown in Fig.6, the parameters of the cutting laser were changed in the transition zone identification badge 110 so that the incoming paper energy was below the threshold of cut paper 20, but still above the reaction threshold marking substance. Thus, the laser beam no longer makes the cut lines with colored edges inside identification badge 110, and generates only colored marker line 112 connected with precise alignment with the cut lines 102 on the border 116 identification badge 110. This exact transition from colored marking lines to cut the lines with colored edges attracts attention during the inspection, is easily detected and, in addition, creates a formidable technical obstacles for unauthorized reproduction.

Another variant embodiment of the invention shown in the detailed drawing presented on Fig.9. In accordance with the one shown here of the embodiment of the invention provides a transparent region 120, which is beyond the identification mark 130 has the Xia family of curves of the cut lines 122 with colored edges 124 and family marking lines 126 without sites with slots. Cut lines 122 and marking line 126 can represent, for example, equidistant curved lines, curved and divergent lines or straight and radiating lines. On the border of the identification mark 130 color marker line 126 and the cut line 122 with colored edges move with the exact combination in colored marker line 132.

In the shown embodiment of the invention lines 122 and 126 in the transparent area 120 are interleaved, however, there are also other sequences, for example, two cut lines 122 and one marking line 126, running after them. Because the family marking curves does not contain the cut lines, it may be placed at an arbitrary angle with respect to the family of incised lines.

In all shown embodiments of the invention, the relative location of the family cut lines and identification mark can generate additional sign of authenticity. For this, various instances of the media family cut lines have a different way in relation to the identification mark, and a different location due to the additional feature of media, for example, with a serial number.

As an illustration, figure 10 shows dualsensor banknotes (a) and (b) with the transparent portion 140, educated equidistant curved cut lines 142, as has already been explained by consideration of figure 4. In the area identification mark 144, in this case representing the nominal bills "10", power cutting laser installed below the threshold of cut paper, so there are no cut lines.

Two copies of banknotes, shown in figures 10 (a) and (b)vary the phase relation of the curved cut lines 142 relative to the identification mark 144. While figure 10 (a) the convexity of the curvature of the cut lines 142 is directed to the left on the top edge of the identification mark 144 (position 1, position number 146), figure 10 (b) they are directed to the right (position 2, position number 148). A possible choice of the phase ratio cut lines 142, for example, in accordance with the serial number of the corresponding instance of the banknote, for example, location 1 for serial numbers in the range 0000001-0100000, location 2 for serial numbers in the range 0100001-0200000, then location 1 for serial numbers in the range 0200001-0300000 and so on. Through visual or hardware validation phase relations cut lines 142 and compare with the value of serial numbers may confirm the authenticity of banknotes. In practice, it is desirable to choose the complex interaction of the serial number is s with relative location, so, while assigning serial numbers are kept secret, a potential counterfeiter was wondering what location corresponds to any serial numbers.

In addition to the different phase relations, for encoding, you can use other characteristics of the family cut lines, for example, tilt (up/down), divergence (open up/down or right/left) or the radius of curvature (increase/decrease).

If the plot with the hallmark covered on one or both sides of the media covering the layer with low transparency, the identification mark is practically not seen in reflected light, but clearly stands out in the visual control of the media in transmitted light.

It is also possible the performance of the site with the hallmark, in which the identification mark cannot be detected visually, but only by a machine. For this purpose, as shown in the cross section of figure 11, in the storage medium in accordance with the invention, a transparent film 150 covers both sides of an opaque covering layer 152. Film 150 includes section 154 with the hallmark that has a lot of curved and/or diverging cut lines 156 and identification mark 158 inside area with hallmark. Who's the one forming the identification mark 158, as shown in figure 11, in the area of film 150 without slots or, for example, in another embodiment of the invention in the area with the cut lines with a different width.

Because the film 150 is coated on both sides with an opaque layer 152 cut line 156 and consequently identification mark 158 are not perceived visually. However, there is a possibility of the detection of the identification mark by a machine, for example, using an ultrasonic sensor 160. Appropriate combination of identification marks that can be recognized only by a machine, ID, binding the relative location of the family cut lines and identification mark, as has already been explained in the description of figure 10.
