The present invention concerns a document with protection against forgery containing protective characteristic in the form of an image, which is formed holes and is shown in shades of gray when considering on a light background.

This document is known from WO 98/19869.

Although the document in question, known from the prior art, provides very good protection against forgery, the importance of the development of new security features, taking into account the technical UNISA least a certain number of holes, forming part of the image formed by the holes extends relative to the main plane of the paper at an angle different from 90.

This hole cannot be made very small drills, and must be made by laser, which requires, on the one hand, large investments, and, on the other hand, a high level of technical knowledge.

This method of execution holes allows you to change the angle to obtain the intensity of the gray color.

In addition, as with conventional straight holes, there is a possibility of changing the density of holes and their size, i.e. their diameter.

The holes preferably form an image.

It should be noted that the image formed by the holes can be to a certain extent subjected to the “image processing”. Through image processing can be compensated signs images, lost due to the required quantization. An example of such image processing is the selection of paths.

The invention is applicable also to the generated holes to the drawings, which represent an image, and are bookonline holes, of course, can be combined with conventional straight holes. This combination provides the possibility of introducing additional images. The main image that is made variable with the opportunity to display Grays, formed, for example, straight holes, then as an additional feature, for example, in the form of a logo or letters formed by the inclined holes. The angle of slope or other features of inclined holes can be selected so that under normal viewing it at an angle of approximately 90appears normal image, but when viewed at a different angle becomes visible second image as a logo or letter combinations.

Another example is the formation of two images on the media in the same place, though from different angles, so that each eye saw its own image, and thus there is a stereoscopic image.

Obviously, this can be varied in numerous ways.

While it is preferable to use a method that allows the document to be protected, is irradiated with the laser generator with two positions. Of course, you can use two laser generator, though, the con is another position, in which it is irradiated by the same laser generator from a different angle.

In those cases, when the laser oscillator is close to the document, you can also holes at an angle different from 90°; this is achieved by the fact that to make the holes the laser beam is moved within the conical or pyramidal space. Thus, the image whose angle of inclination of the holes increases with increasing distance from the center of the image.

According to another preferred variant embodiment of the invention, the cross section of the holes in their transverse plane is made non-circular. The use of laser generator provides the possibility of formation of such holes is adequate control over the provisions of the laser spot. In any case, it is almost impossible to achieve by mechanical means due to the subtleties of the structure of the desired image.

According to another preferred variant embodiment of the invention, the displayed image is hidden code. In this case, can be used the methods already used in the technology of printing production, according to which you can make izmenitca give a perceived code.

And Vice versa, can also be obtained directly visible code. This code can be used, for example, to identify the machine on which was the appropriate product. Thus, it can be identified by the corresponding machine in case of misuse.

In addition, according to the invention, it is proposed to form holes in the protective element, placed on the media, such as optically variable element type hologram or Kinegram. Such security features are not available for a person of a sort that falsified document, as they operate only between one supplier and one buyer. If such protective sign to provide additional personal image formed by the holes, the face of a sort that falsified documents will also be deprived of the possibility to transfer the item from one document to another.

In those cases, when the image formed by the holes corresponds to another image made on the document, you can have a matching image. This allows you to have two exactly identical image.

It has the advantages of: complicated problems for a person of a sort that falsified documents, and the deceiver, audits by the positive surface area.

Hereinafter the present invention will be explained with reference to the drawings, in which:

Fig.1 shows a view in the context of the first variant of execution of the document according to the present invention; and

Fig.2 shows a view in section of a second variant of execution of the document according to the present invention; and

Fig.3 shows a view in section of a third variant of execution of the document according to the present invention; and

Fig.4 shows a view in section of a fourth variant of execution of the document according to the present invention; and

Fig.5 shows a view in section of a fifth variant of execution of the document according to the present invention; and

Fig.6 shows a schematic detailed perspective view of a sixth variant embodiment of the invention; and

Fig.7 shows a schematic detailed perspective view of a seventh variant embodiment of the invention; and

Fig.8 shows a view in section of the eighth variant embodiment of the invention, which also serves to explain the method used it, and

Fig.9 shows a view in section of the ninth variant embodiment of the present invention.

In Fig.1 shows a cross section of the document 1. The document 1 is made of plastic, but it can also be made isoloader of materials of different kinds.

As explained in international patent application with publication number WO 98/19869, such a document is provided with holes. In Fig.1 shows the holes 2. In this first variant embodiment of the present invention the holes 2 does not extend over the entire thickness of the document 1, and is left untouched part 3 of the document.

With the remaining part of the 3 have different thicknesses in different holes. Therefore, they transmit the light to a greater or lesser extent, when the document is kept in the light, this will be an image containing shades of gray depending on the thickness of the remaining portion 3 and the depth of the hole 2.

According to a variant embodiment of the invention shown in Fig.2, the holes relative to the main plane of the document is formed obliquely, i.e. at an angle different from 90. In this case, you can obtain the change in gray tones, changing the angle. This is due to using dash-dotted lines in Fig.2.

In addition, as shown in Fig.3, it is possible to change the width, i.e. the diameter of the holes 4. Of course, you can combine both types of changes. Moreover, can one of these two types of changes, or both, combined with the density change of the location of the holes.

To the.4.

Direct review of the document, as shown in phantom lines in Fig.3, for each of the holes reveals similar gray tone. This gray tone can be varied by changing the density or size of the holes. In this case, it is possible according to the invention to form the image.

Due to the fact that the holes 4 of both kinds are inclined, you can ensure that these holes additional information, for example, having them in the form of letters or logo. Of course, it will be seen only by looking at the image at a certain angle.

In a variant embodiment of the invention shown in Fig.5, openings in both cases is made in the form of a cone or truncated cone. Here the change in the apparent gray tones can be achieved by changing the “depth” of a cone or a corner solution. Thus, a combination of changes in the depth of the holes and change their diameter. Holes 10 thereby are, for example, end-to-end, while the holes 11 - deaf.

In addition, as shown in Fig.6, holes may be formed to a shape different from a circle, for example with a rectangular shape 6. The rectangular opening is difficult to OBRAZOVATEL thus, so he formed a hole with such a contour that is possible with a thin enough focus. Obviously, there are other possible forms, namely triangular, square, oval and so on

In Fig.7 shows a variant in which the document is provided with a layer 7 bearing printing ink. This layer is not particularly noticeable, when the holes are formed by laser; this layer is also removed by laser. In cases where will attempt to provide such an instrument holes by mechanical means, for example by drilling, printing ink will otmazyvatsya that will be clearly visible.

Such an embodiment can also be applied to layered cards, inner layer of which has a color, for example white, which is different from colors of the other layers.

In Fig.8 shows how you can use the same laser generator 8, to form in the same document 1 in its different positions to direct the hole 5 and then inclined hole 4. Of course, important here is the ability of a sufficient deflection of the laser beam 9, which extends from the laser generator 8. In addition, the required precision stops, etc. to provide the necessary precision when placing documents the EC, in Fig.9 shows a variant embodiment of the invention, in which the laser generator 8 is placed relatively close to the document 1, so that the angular deviation obtained apertures that extend at different angles.

In addition, it is obvious that within the present invention countless possible changes to the shown variants of embodiment of the invention.
