The technical FIELD

The present invention relates to a security feature, particularly for banknotes, cards, badges, etc. that have a high potential for protection against forgery.

PRIOR art

As you know, as technology develops, and devices for copying graphic elements printed or placed on the paper for making money, become widespread, has increased and is still the need to have security elements that can be introduced at least partially into the paper for making money. One of the elements, which are continuously developed and studied, is a security thread, which is usually inserted at least partially into the paper for the manufacture of banknotes.

Over the years, the security thread has undergone constant, but a significant development so that it is still one of the most faked items because its fake is difficult even for experienced counterfeiters.

Among the protective strands can be identified, for example, metallic thread with a negative image of the text, i.e. the filament is equipped with a plastic substrate on which is deposited at least one layer of metal, with letters, labels, etc. performed on the wrong layer by removing the metal in the fields of letters and/or labels.

In EP 319 157 disclosed above described method.

For example, also known thread in which to improve the performance of protection, added at least one full-surface layer, which for this reason covers and area without metal and metal area printed with ink having a fluorescent property.

There are other types of threads, in which heterogeneity of metal inserted between the blocks of letters, so that the conductivity can be detected in certain lengths.

However, sales of the metallized strips "transfer" made all these types of threads endure significant counterfeiting, which has led to the need to create a partial detalizirovannoi thread, which thus leaves, letters small amount of metal that can be detected using appropriate laboratory equipment.

Therefore, in this last type of threads letters demetilirovanny only partially. Patent application WO 2004/014665 and WO 2004/098900 belong to the so-called partially detalizirovannym threads of the type indicated above.

There are also the types of threads that can be detected by magnetic sensors. In EP 516 790 describes the thread in which the designated magnetic field is inserted between the letters formed by implementing the full demetallized the AI, so the thread can be detected this way and as conductive (due to the presence of metal deposited in a continuous form), and by magnetic sensors (due to the magnetic elements placed over the metal layer and below, but never inside the letters.)

Therefore, in EP 516 790 described protection device in which characters or letters fully demetilirovanny.

Usually, a coded magnetic thread is made in real time by applying a magnetic zones in the fully metallized polyester substrate; these zones are composed using a single type of magnetic ink and are separated by spaces, which create a region without a metal material used to create texts. Obviously, as soon as it was revealed the presence of magnetic zones, their coercivity and residual magnetism can be easily installed, and consequently, the magnetic material can be used to create a counterfeit or fake; thus obtained code produces the same signals and, therefore, the same code, and when it detects longitudinally (along the axis of the thread), and when it finds across (reading at right angles to the filament).

Security threads with magnetic fields performed using a single type of magnetic ink, powersalesmobile, again with the help of technology transfer. In fact, it is possible to create a tape or strip, which has negative signs, with metal transfers, which later transferred magnetic elements between blocks of letters and in continuous form, and in the intermittent form, in order to create a magnetic codes. In order to create an industrial by the thread of the type indicated above, it is enough to have a rotary printing machine with many sections of the press as described above also in EP 516 790, printing on transparent material (usually polyester) marking using a disposable paint, carrying out full-surface vacuum metallization so as to cover the removed paint, remove the paint and subsequently also the metal that covers them, thus leaving marks that are identical to the labels printed using a disposable paint, and subsequently re-printing with magnetic inks continuous or discontinuous zones in areas that were not demetilirovanny and which, therefore, adjacent to detalizirovannym areas.

Thus, the presence of the magnetic elements are not visible using conventional instruments for inspection (to the naked eye, optical magnifying device, and so on), because they are always covered with metal. Magnetic elements are visible only with the help deter ejstvujuschij devices used for detection of magnetism, such as magnetic scanners or lenses with a liquid magnetic ink, is inserted into the vacuum.

The INVENTION

The present invention is to create an element of protection, particularly for banknotes, cards, badges, etc. with magnetic elements in which the magnetic potential difference regions cannot be detected using conventional instruments to detect existing magnetic codes created on the protective threads.

Within this task, the objective of the invention is the creation of a protection element, particularly for banknotes, cards, badges, etc. in which the aforementioned magnetic elements can be detected only by dedicated sensors.

Another object of the invention is to create a protection element, in which the magnetic elements are of such potential difference to develop different codes, which can be determined even with the help of the device, the feed rate of which varies from one banknote per second to at least 50 banknotes per second.

Another objective of the present invention is the creation of a protection element for which it is fake is even more difficult with respect to known types of elementality, because only someone who knows the basic principle and the location of the zones to determine their contents.

Another object of the invention is the creation of a protection element, which is highly reliable, relatively simple to build and has a competitive cost.

This task, as well as these and other tasks, which will later become clear, are attained by means of an element of protection, particularly for banknotes, cards, badges, etc. containing the first substrate, which is at least partially opaque when viewed in transmitted light, and a set of magnetic zones that are hosted on the aforementioned substrate, in which each of these magnetic areas formed by using the first magnetic material, the second magnetic material or composition of the first and second magnetic materials which are at least partially superimposed on other, and the first magnetic material and the second magnetic material are different values of coercivity, which is determined using a sensor, while the first and second magnetic materials are magnetically saturated, so one of the first and second magnetic materials is not under the influence of another.

EXAMPLES of carrying out the INVENTION

As seen in the drawings, the protection element is provided according to the present invention, indicated generally by the reference number 1, includes the first substrate or the first supporting layer 2, which is at least partially opaque when viewed in transmitted light, and which caused the magnetic areas 3, 4. The substrate 2 is properly made of plastic, such as polyester, while the opacity is provided by the presence of sediment metal or paint with coloring agents and/or pigments, or change colors, or materials obtained from mixtures of such materials.

One of the features of the invention is that the magnetic areas 3, 4 contain at least two types of magnetic zones, respectively formed first and second magnetic materials, which have different values of coercivity and residual magnetism which is identical or different; the difference in coercivity, and identical or different residual magnetism aim to develop at least three different codes.

In particular, the magnetic areas formed by the magnetic paint, the coercivity which is different (for example, 200 OE for the lowest and 3000 OE to high), and the residual magnetism which may be identical or different depending on the type of encoding equally, when they are placed in series is, next to or superimposed on one another.

Suppose that the sequence of the nine magnetic areas 3, 4, spaced from each other with the help of 4 (mm, mm) (more than 4) gap printed on the threads of width 2 (mm, mm) with identical residual magnetism, but in which the first, third, fourth, sixth and ninth areas have a coercivity of $ 4500 OE, while the second, fifth, seventh and eighth zones have a coercivity of $ 300 OE.

By focusing all zones 3, 4 using the magnet with high coercive force (15000 (G, HS)) and define them using the first read head sensor reading get consistently six zones; a second magnet with a reduced coercive force (2500 (G) HS), but sufficient to rotate 90 magnetism zones 4 with low coercive force, allows the second read head to determine only the remaining magnetic zones, which are areas with a high coercive force.

In Fig. 3A-3C graphically represented, respectively, the signals that can be detected using the sensor reading for the protection element 1 according to the first variant implementation of the present invention according to Fig. 1 and 2, while in Fig. 3A graphically presents the signals that can be detected from all of the magnetic areas 3, 4; Fig. 3b graphically presents the signals that can be detected from the magnetic zones with high coercivity, and in Fig. 3C graphically presents the signals that can be detected from the magnetic zones with low coercivity.

Essentially, he was offered the protection element, such as a security thread, which contains the first code worked out all of the magnetic areas 3, 4, which are (read the first reader head), the second code is generated only areas 3 with a high coercive force (read second read head), and the third code is generated only zones 4 with low coercive force (the result of all of the zones 3, 4 minus zone 3 with a high coercive force). This is accomplished by using, for example, the same value of residual magnetism as for zones 4 with low coercive force, and for zone 3 with a high coercive force.

In order to additionally increase the degree of impossibility of tampering protection element according to the present invention, it is possible to perform zone 3 with a high coercive force, which are placed so that they were at least partially superimposed on the zone 4 with low coercive force (see, Fig. 5), in which the amount of residual magnetismo equal to the residual magnetism of the neighboring areas, and if they have a high coercive force, and if they have a low coercive force.

Magnetic zones are saturated in magnetized condition, so that the mutual magnetized the awn of the first and second magnetic materials, having different coercive values is suppressed.

This provides magnetic isolation between different magnetic materials.

In other words, the saturation of the first and second magnetic materials has such an effect that one of the first and second magnetic materials is not under the influence of another.

The third magnetic material may be performed, at least in part of magnetic zones that are at least partially superimposed on the first magnetic material and/or the second magnetic material. This third magnetic material obtained by mixing the first and second magnetic materials.

As paints with a high coercive force, and paint with a low coercive force can be obtained by mixtures of oxides or with only one type of oxide, all of which are aimed at achieving significant different coercivity.

This overlap can occur, for example, by imprinting, or even better, by joining in the register of the two bearing layer or layers 2, 5 of the substrate, in which, respectively, the first layer contains zone 3 with a high coercive force and residual magnetism, for example, equal to 100 (nW/m, NW/m), with other areas 3 with a high coercive force and residual magnetism, for example, equal to 50 (nW/m, NW/m), while the second supporting layer 5 contains the zone 4 low the coercive force and residual magnetism, equal to, for example, 100 (nW/m, NW/m) and 50 (nW/m, NW/m).

If two layers 2, 5 are connected to the register, blocking zone 50 (nW/m, NW/m), receive the sequence of zones, the signals are focused by using a magnet with high coercive force and read by the first read head are very similar sequence, which causes only the length of the zones and the corresponding gap.

Then by turning 90 to the magnetic flux zones 4 with low coercive force, using a weaker magnet, for this reason, for example, magnet 2500 (G, HS), receive a number of signals in the sequence, which is equivalent to the signals of the first head, but with an electric signal, which is 50% weaker in areas obtained by overlaying each other inks, or by connection.

Placing the threshold of detection of the analog signal at different levels (as shown, for example, by broken lines in Fig. 6b, 6c), you can get more codes, because the bits that are initially have a high value as soon as the decrease can be detected or they can be neglected, even more, by placing the noise threshold is different.

Additionally, using, for example, the base module 4 (mm, mm), which should be applied to the strip and/or the appropriate clearances, much easier, if all bits of the first code and partial availability of the second and third code to recognize the codes, because they depend on the underlying 4-mm module.

Another way to fabricate zone, the characteristic of which is that they are made using inks with different coercivity and residual magnetism which is initially identical, then is different, when such zone is additionally magnetized using the magnet, the flux of which is rotated 90, is to run them through a single printing ink, which contains a mixture of oxides (such as, 50% 4000 OE +50% 300 OE), thus, depending on the percentage content of the mixture used can have a number of opportunities to get different codes.

Another example is to use, for some areas of the printed ink only pigment in 4000 OE and for the remaining zones of the printing ink with a mixture consisting of 33% of the pigment with 4000 OE and 66% pigment with a coercivity of 300 OE. Thus, get the area prepared by using mixtures, which are pre-programmed to produce magnetic signals as a function of the strength of the magnet used, the orientation of the flow and usage.

Systems of this type provide a number of manufacturers in order that significantly increase the degree of impossibility of tampering in addition to providing validation den is the author of the sign, which contains a security thread, as at low speed and at high speed.

Suppose that the security thread, which is 2 (mm, mm) in width, has a first supporting layer 2, made of plastic, such as polyester, which caused full aluminum surface 10 by vacuum metallization, in which through a process of demetallization is completely or partially deleted text and/or graphical symbols in accordance with a given graphical markup, given the thickness of the aluminum.

Thus, the magnetic areas 3, 4, for example, length 2 (mm, mm), spaced from each other with spaces 10 without magnetic material on a length component, for example, 4 (mm, mm), applied in such a way between one text and another. Magnetic zone 3 is made by the use of paints with a high coercive force, alternating magnetic zones 4 with low coercive force, residual magnetism of these zones are completely identical to the tolerances specified in the various processes of manufacture.

The first supporting layer 2 is then combined with additional or second bearing layer 5 made of polyester, which is always metallizer and demetallizing in areas at least partially, in order to leave a free zone, where was located the text, so that they can be read by transmitted light.

In the areas of WTO the CSOs supporting layer 5, which correspond to the areas where the magnetic areas 3, 4 have already been printed on the first support layer 2, type a new magnetic zone 3 different surfaces: one difference may be, for example, 66% of the coating zone, placing the magnetic material at the edges of the threads.

Suppose that the width of the thread that was supposed to be, for example, 2 (mm, mm), divided into three parts: one is the first area the size of 0.66 (mm, mm), made of magnetic material, the space in 0,66 (mm, mm) and second zone component 0,66 (mm, mm) of the magnetic material. In doing so, the codes that are available on the threads, as described previously, the codes can be detected by appropriate sensors, which are described next.

This last type of thread, therefore, has an additional feature, which is to highlight the presence of two additional zones, only when the document is read transversely to the thread.

It is also clear that the second zone 4, printed on the second support layer 5, made of polyester, can also be fabricated directly on top of the first areas 3 that are already on the first support layer 2 made from polyester.

It is also clear that the magnetic areas 3, 4, made with different coercitivity can have the same and/or different residual magnetism defined by a different number is inanaga material, there is for equal size and thickness, or the difference in the thickness of the coating for equal area, or oxides, which have the same coercivity, but different residual magnetism (oxides of different physical origin) or between mixtures of any of the foregoing.

In Fig. 6A, 6b, 6C graphically presented, similar to Fig. 3A, 3b and 3C, the signals (codes)that can be detected by the protection element made according to the second variant of implementation of the present invention.

All the previously described thread not provide the orientation of the magnetic direction of the magnetic printing ink during the transition from wet ink to dry printing ink, which is a sign printing.

Additional customization can be carried out, for example, by focusing iron oxide, which is used for zones 3 and, therefore, has a high coercive force at the time of printing, when it is still wet, and then forming the top or connection in the wiring of the magnetic zones 4 with low coercive force. In this case, the magnetic zone 3 always have orientation North-South, while zone 4 can be orientated North-South or South-North (turn magnetism 180) or negated (for reading, which is parallel to the thread), turning magnetism zones 4 only 90.

For Cohocton to find the codes made so you can, for example, to use the method of reading described in EP 0428779 type.

In this patent actually disclosed method, which is based on the recognition zones, separated by spaces, the magnetic characteristics of which have different coercivity, in order to generate two sequences of signals generated by the first magnet orientation, the first read head, a second magnet orientation for rotation, magnetism and the subsequent second read head with an additional magnet reorientation. This way of reading therefore entails many elements placed in series.

In the case of this application was mainly detected that the magnets and the read head must be placed at an angle in the range from 40 to 50 with respect to the longitudinal and/or transverse to the continuation of the protection element.

Preferably, this angle should be 45.

Protection element made thus detected by the sensors, as described, and therefore, three codes that exist in the monetary sign, can be used, for example, different devices designed for different operators, such as ordinary shopkeepers with the first code, the commercial banks with the first and second codes, the Central banks with all the Tr the two codes.

To summarize, three code protection element defines all of the magnetic zones that exist, the magnetic areas formed the first magnetic material, and magnetic areas formed the second magnetic material, respectively, the value of the coercivity of the first magnetic material is higher than the coercivity of the second magnetic material.

It is noted that the protection element according to the present invention can be, for example, security thread, or a protective tape or strip.

In addition, the protection element according to the present invention may contain at least on one of its sides, holographic, and/or changing color, and/or mono - or multi fluorescent image.

The protection element according to the present invention can be manufactured using the following steps.

First, the first magnetic material (magnetic zone 3 with low coercivity) is printed on the first substrate 2. Then the magnetic zone 3 saturated and analyze the signal coming out of these zones.

Subsequently, then print the second magnetic material (magnetic zone 4 with high values of coercivity) as on areas where there is no first magnetic material and the areas where the first magnetic material available. In the latter case, the second magnetic material will chataut, at least with a partial overlap in relation to the first magnetic material.

Then, both the first and the second magnetic material is saturated and analyze resulting from the first and second materials signals with regard to their maximum values to the maximum amplitude. These signals can all be the same, or different, in accordance with the residual magnetism of each of the printed magnetic zones.

Finally, the second substrate 5 is placed on top of the first substrate 2 with a magnetic zones 3 and 4.
