Protective sign containing the perforation pattern

 

The present invention relates to a document that must be protected from tampering containing protective characteristic in the form of a perforation pattern. The document has a security feature in the form of a perforation pattern containing holes of different sizes, and perforation pattern get through the laser beam. This perforation pattern is a reproduction of the pictures located in the passport. In addition, the present invention relates to a method of applying a protective characteristic in the form of a perforation pattern in the document. The technical result is to increase the protective properties of the document. 2 S. and 9 C.p. f-crystals, 5 Il.

The present invention relates to a document that must be protected from tampering containing protective characteristic in the form of a perforation pattern.

This document is known from international patent application PCT/NL/00119.

In this document relating to the prior art perforation pattern has the form of a symbol or series of symbols. This perforation pattern here is applied in the form of round, rectangular perforations or perforations in the form of symbols. Therefore, these perforating drawings always pry already creates a significant impediment to potential counterfeiters, there is a need in the protective trait that counterfeiting more difficult.

This goal is achieved by the fact that provided the document is protected from a fake containing protective characteristic in the form of a perforation pattern with holes of different sizes, and perforation pattern get through the laser beam and this perforation pattern is a reproduction of the pictures located in the passport.

In this document, the picture is visible when the document cover from the back side, and the document itself can be a passport, in which the protective sign printed on a page other than the one where the passport photograph.

Shades of brightness of the image in the perforation pattern is obtained by changing the size of the perforations or by changing the density of the perforations. Bright shades can be represented large perforations respectively high-density perforations, and dark shades - small perforations respectively low-density perforations.

In addition, in accordance with the invention is provided a method of applying a protective characteristic in the form of a perforation pattern in the document, which sing by electronic image playback, use the laser tool adapted for sequential application of the perforation pattern in the document, and the perforation pattern is performed in the form of playback pictures, located in the passport.

In the process the passport photo can be converted into digital form by means of optical-electronic devices, and perforation pattern is drawn on the basis of digital playback passport photos.

Thus, the perforation pattern extends over the surface of the document and represents an image containing shades of brightness.

Perforation pattern in this case is formed so that, for example, when thus treated, the document is inspected for clearance or placed on a lighting device, the image becomes visible at the location of the perforation pattern.

It is obvious that the creation of such images, representing the shades of brightness, requires the use of advanced technologies. Such technology is not available to potential counterfeiters, and therefore, the documents provided with this perforation pattern, it is very difficult to forge.

Perforation pattern, preferably, is applied when Arial, for example, paper, plastic or textile is completely removed so that when, for example, a fingertip hold on the document, no protrusions or grooves or burrs are not felt.

If, for example, perforating the figure was caused by the forgers using, for example, formed in the shape of a cone needles, necessarily would be formed Cup-shaped edges or burrs, which are easily perceptible by touch. It is, therefore, provides a good means of detecting possible fakes.

According to another preferred variant of the invention, the perforation pattern is a reproduction of the image formed on the document using a different technique.

With the ability to visually compare images and perforation, thus no need to use complicated auxiliary means are not absolutely perfect fake at least one protective means of the two becomes easily recognizable. Thus, achieve a high degree of protection against forgery.

This measure requires that production of the document it is necessary to have means for making a perforation pattern and a tool for creating wired is preobrazovaniya it in digital form to obtain control means, necessary for the manufacture of punching pattern.

According to another preferred variant of the invention, the image made by another technique, characteristic of the document. This gives you the opportunity to personalize the document. It is obvious that it leads to an even higher level of protection.

An important application of the present invention is that the document is a passport, and that the image is a photograph in the passport.

Other preferred embodiments of the invention set forth in the dependent claims. It should be noted that the invention also relates to a method for formation of a protective characteristic in the form of a perforation pattern in the document, in which perforation, a drawing, a laser medium, which is adapted for sequential application of the perforation pattern in the document, where the size of the perforations or the density of the perforations regulate through the electronic representation of the image.

The present invention also relates to a device for implementing this method.

The present invention is disclosed below with what I document in accordance with the present invention; Fig.2 is a detailed view of the perforation pattern shown in Fig.1; Fig.3 is a perspective view of a passport, in accordance with the present invention; Fig. 4 - kind of the banknote with the drawing, in accordance with the present invention and Fig. 5 - stamp, provided with a perforation pattern in accordance with another embodiment of the present invention.

Before the description of the equipment it should be noted that in accordance with this technique, execution shades of brightness, as in graphics, possibly with perforations that are in accordance with a fixed grid, where the size of the perforations is a measure of intensity, and that can also be played hues brightness the use of perforating holes of equal size, where the density of the location of these holes is a measure of intensity. Both, in principle, can be combined.

It should be noted that in the graphical image of the first option is equivalent to the style in which black and white photographs reproduced in the Newspapers, and that the example of the second technique can be found in the Dutch series of postage stamps, where the image of Her Majesty the Queen represented by dots with variable density improvement is EPA 1 records an image on pictures 2 in the passport, converts it into electronic format, and delivers the thus obtained signal to the computer 3, in which it is stored.

The device shown in Fig.1 also includes means 4 for generating a laser beam, which is controlled by the computer 3. This control applies not only to the intensity and focus of the laser beam 5 emitted by the laser medium 4, but also to the direction in which the emitted laser beam 5. You can change this direction in two planes for applying perforating figure 7 on the document 6.

It should be noted that these laser tools known from the prior art; to change the orientation of the laser beam using a system of mirrors, not shown in Fig.1.

You can also have a fixed laser medium 4 and to cause movement of the carrier, on which is placed a document 6. You can also cause movement of the carrier in one direction and movement of the laser beam in the other direction; the choice between different possibilities depends on the technology used.

It is very important, however, that the perforation figure 7 contains sprocket holes of different diameter, where the diameter is a function of the brightness of the reproduced image. The perforations is or fewer holes.

This in more detail is shown in Fig.2, showing a detail of the perforating figure 7. It is seen that in this embodiment of the invention perforation pattern formed perforations 8, which are arranged in the shape of a regular grid, for example, a rectangular grid. Hole sizes are a measure of the brightness of the image reproduced perforation figure 7, in this case, the 2 photos in the passport. It should be noted that the size of the perforations regulate continuously, in principle, the analog way; by processing the digital computer can be obtained limited, but still a large number of brightness levels. Tests have shown that it is nevertheless possible to obtain a reproduction image which forms an adequate display of the corresponding image and can easily be compared with him.

It is obvious that in this way receive a good sign of authenticity that is hard to copy.

In Fig.3 shows the passport 9 to which is attached a photograph of 2, for example, with glue, tubular rivets, or other attachment method. On the same page next to the photo cause perforation figure 7, so the processes page of the passport into the light.

In another case, also possibly causing perforation pattern on another page of the passport, with a quick visual comparison. This makes it more difficult falsification, as it requires you to forge at least two different pages. You can also put the image of increased size, reduced in size or modified in another way.

In Fig.4 shows a banknote 10 which is provided with a sprocket figure 11, in this case, in the form of owls. This perforation pattern does not apply to another image that is located on the banknote, but forms an extremely protective of the sign itself; can be provided to the banknote such a protective sign. Again it should be noted that unlike prior art is that the image 11 is different shades of brightness, for example, gray tints. In another case, there may be used an arbitrary mesh, in this case, applying the same dimensions of the perforations, and the density of the perforations vary for playback grey shades.

The same applied to a postage stamp 12 shown in Fig.5, which supply the perforation pattern 13 as an image of Her Majesty Caroliniana.
