The invention relates to the control elements for printed objects, in particular for securities or their analogues, containing the first pattern on the first side of the specified object containing at least one first raster.

Known control elements are used to prevent forgery of securities, in particular the copying paper money. To impede or completely prevent such fraud by photocopy or use a scanner connected to a color printer, in addition to known means, such as watermarks in the paper, began to apply the control elements, usually referred to as protective elements.

Technical advances in production scanners and photocopiers allow you to use them for everyone. As a consequence, there is a need to increase the number and improve the protective elements.

To perform protective elements on securities developed various technologies. The first technology is the so-called technology of application of the latent image color. The idea of this technology is the printing on securities special image that cannot be seen with the naked eye. To do this, use an assignment of colors and contrasts. When Photocopying or scanning securities is printed patterns in a hidden color this picture becomes visible to the naked eye, that facilitates detection of forgery. The method disclosed in publication EP 0882599 drawing the image hidden color.

In European patent application EP 0509916 described paper money, containing a graphic image and two stacked on top of each other protective sign, each of which is made in the form of a water grid, the first sign is made in the form of periodic water grid, and the second is the result of the division printed graphics on the parallel bars, encoded binary code and are located symmetrically to the axis of symmetry of the document, and the wave water grid has a General direction that is not perpendicular to the direction of the stripes printed graphic image, and the overlay of these characters to each other does not allow you to read each of these characters individually.

In the publication EP 0710574 described method of generating pattern and the protective pattern consisting of multiple lines. In accordance with outlined in this patent application the principle of simultaneously modulate the space between the lines and change the width of these lines, while maintaining constant the ratio between the line width and space between lines so that visually when considering the naked eye appearance of the picture has not changed much. This technology is especially prefer the d, if you want to calculate the distribution of the lines depending on the type of photocopiers and scanners, from which I want to protect.

The present invention is to improve the known control elements for the difficulty of counterfeiting the securities, securities, i.e. the implementation of this pattern, shifted to areas which cannot be seen with the naked eye and cannot be reproduced via photocopier, or to scan.

According to the invention proposed is relatively simple in execution of the control element, allowing easy control over the printed object.

The control element in accordance with the present invention is defined by the features stated in the independent claim 1 of the claims.

In dependent clauses 2-7 claims defined some methods of performing the present invention.

In dependent clauses 8 and 9 are defined respectively valuable paper and the sheet containing at least one control element in accordance with the present invention.

The figure in accordance with the present invention is used in double-sided printing, when the register between the front printing and back printing is particularly important.

The essential feature element in accordance with the present invention are the two which is the fact that it can be used for protection against forgery or for monitoring the print quality during double-sided printing of the printing object, in particular, to monitor the case when double-sided printing.

Further the present invention explained in the description of the preferred variants of the embodiment with reference to the accompanying drawings, on which:

Figure 10 - drugalcohol of the drawing, in accordance with the present invention.

11 is a schematic illustration of the sheet containing the printed objects, such as paper money, with each bill contains a control pattern in accordance with the present invention, and the sheet also contains a control figure, according to the invention.

The first method for executing drawing according to the invention is described with reference to figa-1D. Primary background 1 (figa) contains a set of parallel lines 2 and applied on two sides of the printed object printed in register, i.e. lines 2 are exactly against each other. To complete the picture when printing at least one side of the printed object change the shape of lines 2 through displacement plots of these lines. The modification shown in figv, where the unchanged line indicated position 2, and modified lines sequentially marked positions 3-11.

Line 3 contains multiple serial sections indicated by the positions 3A-3g (pigv). Similarly, lines 4-11 contain a consistent, properly indented areas. As shown, this background can be printed on the obverse and on the reverse side of the printed object. On figs shows the background, identical to the primary background, shown in figa. This background is printed on the other side of the printed object with respect to the ISM is United to the background, shown in figv, but with full respect of the register with the specified modified background. The result of such full compliance register is coincident straight lines or parts of straight lines when viewing the printed object using x-ray, whereas the shifted serial sections 3A-3g and plots lines 4-11 viewed by probing between matched the specified lines. The result is viewable only by probing the special pattern shown in fig.1D. If the offset sections form a predetermined special image, it is easy to check that is there at the x-raying is a predetermined image, and in this way control at the same time the authenticity of the printed object and register double-sided printing.

Thus, when the overlap of the two lines marked on figa and 1C position 2, get lines marked position 2 (fig.1D), and the result of the blend line sections 3 and 3A-3g (pigv) on the appropriate line 2 (figs) receive line 12 (fig.1D) with thickened portions 12A-12b.

Similarly, the overlay lines 4-11 and indented sections on the corresponding lines (figs) results in lines 13-19 (fig.1D) with thickened portions 14a and 14b, 15A, 16A, 17A, 18a and 18b, 19a and 19b, 20A and 20b, respectively.

Line figa-1D specifically shown in the enlarged view for Lu is our understanding of the invention. In fact, the lines have a thickness of from 10 μm to 500 μm, and the intervals between the lines have a width equal to approximately one half to double the line width, i.e. from 5 μm to 1000 μm. So you figure, the offset areas which cannot be seen with the naked eye and cannot be reproduced via photocopier, or to scan, so they are missing on a fake printed object. Check radiography allows to determine the absence or presence of the element and to control register reverse printing, because only in full compliance with register, you can receive the necessary element.

In the example shown displaced sections of the lines form the letter "K". Of course it is possible to get more letters, combination of letters or figures, it is important to be able to change the color density when scanning to form a character that is easy to detect if the installation of the register is done incorrectly.

This method is not limited to shift up, shift can produce down or, if the background line rotated by 90°, - right or left, on the front or on the reverse side.

In the first embodiment shown in figa-2D, simultaneously changed the background line on the front side and lines on the reverse side. On Pervin the m background 1 (figa) with parallel lines 2 on one side, for example on the front side, shifted serial sections of lines (pigv). The resulting line 21 contains a sequential sections 21A-21g, and each of the lines 22-29 also contains the offset areas (pigv).

In the first embodiment, also changed the background line on the other side of the printed object (figs), that is, on the flip side, if you count the first side face. However, in this embodiment, the change in parcel lines is reversed between the underside and face. If we assume that figv shows the front, then the line parts, for example, 21A-21g are skewed towards the upper edge, while figs, which is the flip side, lots of lines, for example, 31A-31g biased towards the bottom of figs.

The result of scanning the overlay figv and 2C shown in fig.2D. In this case, the result of the superposition of lines and shifted parts of lines, if the case is correctly installed, form a pre-defined sign-dependent offsets, which subject line. Overlay lines on figv and 2C results in line 2 on fig.2D. Overlay line 21 with sections 21A-21g (pigv) on the line 30 and the sections 30A-30g (figs) results in a line 30 and advanced sections 39A-39b (fig.2D)if the register is set correctly. Similarly, the combination of lines 22-29 (pigv) with lines 31-38 (figs) pozvolyayuschei when scanning lines 40-47 (fig.2D) with extended areas if the register is set correctly.

The advantage of this variant execution is that, because it performs the reverse change of the two backgrounds, bias may not be as significant than the change of only one background, because the offsets on the front and back sides complement each other. To verify this, it suffices to compare figv and 2B. From this it follows that since the bias on each background are smaller, and to distinguish them with the naked eye or to reproduce using a photocopier or scanner harder in comparison with offsets only on the personal background or the reverse background. However, the effect in the x-raying is not reduced, as by probing bias complement each other and remain visible.

This is not limited to shift up or down. You can also offset to the right or to the left on the front side and/or on the flip side, if the background line rotated by 90° in relation to the lines on figa-2D.

The third variant of the first method of implementation described with reference to figa-3D. This option is similar to the variant shown in figa-2D. The difference lies in the carrying out of alignment when double-sided printing. In the variant shown in figa-2D, it was necessary to accurately impose on each other is the turn personal background and working background, to select the offset sections (21A-21g or 30A-30g) between these lines.

In the variant shown in figa-3D, during the duplex print line, combining them with each other, and Vice versa, shifting them relative to each other, alternating so that each line on the front side caught between two adjacent lines on the reverse side. Offset creates an empty space corresponding to the offset sections of the lines to the control element formed by the absence of print, and not the presence of the offset areas. For example, if the front side of the printing line 2 (figv and 3C) and 48, line 57 on the reverse side will be located between lines 2 and 48 of the front side, and so on for successive lines 42 to 2 (pigv), between which are sequentially printed on the other side of the line 58-66 (figs). On fig.3D shows the result of printing while scanning. As shown, the frequency lines increased, and when the offset sections of the lines formed in the gaps, for example, 67 and 68 forming a specific image, in this case the letter "K". The result can easily control register printing by scanning.

On figa-4D is shown in a more General form of the control drawing, given by way of example, allow a more complete understanding of the effects generated by the drawing in accordance with us is oasim invention. On figa-4D presents a method of execution in which personal background and current background contain the offset of the line parts. Primary background 1 (figa), contains a set of parallel lines 2. On FIGU first four lines 2 above has not changed, then, since the fifth line, shifting areas of successive lines 21', 22', etc. similarly figv. Similarly, on figs the first four lines 2 are not affected, since the fifth line 31', land lines displace similarly figs. Line figv and 4C print mode register on the obverse and on the reverse side of the object. If the case of double-sided printing is set correctly fig.4D by probing receive the corresponding fig.2D.

According to the second method of performing background 67 (figa-5D) consists of concentric circles (figa). Similar to the previous methods shift the plots concentric lines in the framed areas 68, 69 (figv and 5C). As in the previous cases, if the case of double-sided printing is set correctly, these shifts result in a predetermined image which becomes visible when scanning, as shown in fig.5D. In this case, this image is also the letter "K".

On figa-6D shows a third method of implementation, according to which the background 70 formed by wavy lines. Similarly to the previous method is m run displace parts of lines for forming a predetermined character or image. You can shift parts of lines or only on one of two sides of the printed object, or on two sides for when scanning the desired image. In the example shown in figa-6D, changed the background on the front side (pigv) in the zone 71 and on the reverse side (figs) in the zone 72. When combined, if the case is correctly installed, get the result shown in fig.6D, which appears when scanning the letter "K".

On figa-7D shows a fourth method of execution in which combine visible to the naked eye change the background lines, as well as offsets in accordance with the present invention. In this way use the primary background 73, consisting of parallel oblique lines (figa).

On the obverse there is a background 74 (pigv), visible to the naked eye, i.e. offset for forming a predetermined mark 75, in the described embodiment, the number "200". At the same time carry out the offset sections of lines, as described above, for example as shown in figv, this bias is very small and cannot be seen when considering only the front side. Similarly, received from the reverse side, as shown in figs. In current background 76 visibly change line, forming a consecutive letters "DLRG" in the background. At the same time the background lines alternate, the AK was described above (figs), changing them slightly, so they were not visible to the naked eye, but thus forming the specified character. The result when scanning is shown schematically in fig.7D, where you can simultaneously see the figure "200", the letters "DLRG" and the reference picture, which in this case is the letter "K", which appears when the register is double-sided printing is set correctly.

One advantage of this method is that, because the images, numbers and letters are formed so that they are easily discernible in the background, whether it's personal background 74, or working background 75, then change the lines for the formation of a protective figure, even harder to see when considering only one of the backgrounds 74 or 75 no show-through. Conversely, when x-raying (fig.7D) is an effect in accordance with the present invention, it becomes possible to control.

Another way to run, which used the principle of the present invention, shown in figa-8D. In this case, for forming the backdrop is not used line and raster - background 77 (figa). Similar to the previous methods of performing for the formation of a given character in a certain way the raster deform. In the presented example the raster deform 78 on the front side (pigv) in areas 79 and 80 and raster 81 on the reverse side in the zones 82 and 83 (figs). After printing, if p is gistr was installed correctly, the corresponding changes in the areas of rasters on the front and back sides form a definite sign that is visible when the x-raying. In this case, the formed mark is shown schematically in fig.8D in the form of letters "OK".

Another way of carrying out the invention is described with reference to figa-9F. In this way the figure in accordance with the present invention is used for alignment of the printing cylinder when installing the machine for double-sided printing. Since in accordance with the present invention has the ability to control register double-sided printing on a printing object, then this principle can be applied to detection of counterfeits, made by Photocopying or scanning, and to adjust the register of the double-sided printing of the printing press by creating for this purpose a special sign. In the shown figa-9F embodiment, the control character contains two arrows in opposite directions. The primary background of the front side 85 consists of consecutive parallel lines 86 (figa). The primary background of the reverse side 87 consists of consecutive parallel lines (pigv). Each line 88 includes the additional offset areas a-88f (pigv). Feature lines 88 (pigv) is that their height, for example the length of the sections 88b and 88d equal to the width of the lines 86 (figa). On figa the 9V shown part 89, framed by a dotted line. Height is important, and allows you to set the register double-sided printing. If the case is correctly installed, backgrounds 85 and 87 are aligned, that is, lines 86 and 88 are aligned, and by probing personal background closes the current background. In other words, when scanning an image will appear, shown in figs, line 89 constant thickness.

In case of improper installation of the register and the longitudinal offset prints on the front and back sides of a situation arises, shown in fig.9D or 9F, depending on the actual displacement. If the current background is shifted upward with respect to the personal background, i.e. the cylinder which prints the reverse side, "ahead of" the cylinder, printing the front side, the areas of a, 88f and 88h appears at least partially by probing, as shown in the lower part fig.9D and straight sections 90 will correspond to overlap each other direct 86 and a, e and 88g (figa and 9B). If parcels are located so that they form a given image, such as two directed to the opposite sides of the arrow, and if the bias is directed upwards on the flip side, the arrow pointing up will be dark (left side fig.9D), and click the down arrow will light (right side fig.9D). Conversely, if the offset is pointing down, that is when x-raying appears plots a, E and 88g (fige), and line 90 of this figure will be the result of the overlapping each other lines 86 (figa) and plots 88p, 88f and 88h (pigv). In this case, the dark arrow pointing down and the arrow pointing up will be bright (upper part file).

Such a control pattern allows you to easily control register double-sided printing, the accuracy of the installation related to the thickness of the lines 86 and offsets a-88g. In addition, the stated control means can be used simultaneously for the installation of longitudinal displacement and installation of lateral displacement. It is enough to combine the graphic shown on figa and 9B, with the same figure, in which the lines perpendicular to the lines shown on figa and 9B.

Figure 10 shows another method of performing image in accordance with the present invention. In this case, the offset is masked to further complicate its consideration to the naked eye. In the present example, each line is divided into sections s1-sn. The plot of sncharacterized by a width lnlines and distances dn1and dn2between this area and the corresponding area of the previous line and next line. Control ratio is determined by the first section of the line:

r1=l1/(d11+d12)/2.

This sootnoshenie the line width/average distance is kept constant and equal to r 1for all lines. So, for site snwe obtain rn=ln/(dn1+dn2)/2=r1where ln=r1·(dn1+dn2)/2.

In addition, the lengths may vary along the lines of, in particular shorter sections preferably are located in areas with strong change and provide the best camouflage.

Figure 11 shows how you can combine drawings on the same sheet containing prints, such as reprints of securities. Sheet F contains a certain number of impressions 91 with a matrix arrangement of rows and columns that are next to each other. Each of the prints 91 contains at least one control element 92, is made in accordance with the principle described with reference to figa-8D. The element 92 is used as a protective element to prevent possible tampering with prints, for example, by photocopy or scan. In addition, use two controlling element 93 and 94, performed according to the method described with reference to figa-9F, to set the case of two-sided printing. Control elements 93 and 94 can be, for example, at the edges of the sheet F, and be aligned along two perpendicular between an axis that allows you to adjust the case of double-sided printing on two perpendicular between the lines op the toboggan above.

You can use controls for all types of securities, in particular paper money, Bank notes, etc.

The control element in accordance with the present invention can be used not only to combat counterfeiting, but also to control print quality. For example, when the printing of paper money is easy to check the print quality of individual cuts, controlling the control element. Using a simple and well-known tools, you can see if the check digit. For example, when the illumination of the notes on the reverse side located on the front side of the camera clearly captures the presence or absence of a control token.

You can also change the substrate of the printed object: you can use paper or any other substrate, for example, of plastic, polymer, polyester, or their equivalents. The greater the transparency of the printed substrate, the more clearly manifest when the scanning of the control element in accordance with the present invention. You can pre-preparation of the printing substrate in the print area that contains the control element in accordance with the present invention, for example, using varnish or using a watermark effect.
