Definitions
- the present invention relates to a security element particularly for banknotes, security cards and the like, which has a high anti-counterfeiting capability.
- security threads it is possible to identify for example metallic threads with negative text, i.e., threads provided by a plastic substrate onto which at least one layer of metal is deposited, characters, lettering and the like being formed in such layer of metal by total removal of the metal at the regions of the characters and/or lettering.
- EP 319 157 discloses the method outlined above.
- a thread is also known for example in which, in order to increase the security characteristics, at least one full-surface layer is added which therefore covers both the regions without metal and the metallic regions with ink having fluorescent properties.
- Patent applications WO2004/014665 and WO2004/098900 relate to so-called partially demetallized threads of the type described above.
- threads which can be detected also by means of magnetic sensors.
- EP 516 790 discloses a thread in which detectable magnetic regions are inserted between the letters formed by performing total demetallization so that the thread can thus be detected both as conductive (due to the presence of metal deposited in continuous form) and by means of magnetic sensors (due to the magnetic elements arranged above or below the layer of metal but never inside the letters).
- EP 516 790 discloses a security device in which the characters or letters are totally demetallized.
- coded magnetic threads are currently produced by depositing magnetic areas on a fully metallized polyester substrate; these areas are composed with a single type of magnetic ink and are separated by spaces in which regions without metallic material, meant for generating texts, are generated. It is evident that once the presence of magnetic areas has been discovered, their coercivity and residual magnetism can be identified easily and consequently so can the magnetic material to be used to create a counterfeit or forgery; a code thus provided generates the same signals, and therefore the same code, both when it is detected longitudinally (along the axis of the thread) and when it is detected transversely (reading at right angles to the thread). Security threads with magnetic regions provided with a single type of magnetic ink also have undergone counterfeiting, again with the transfer technique.
- magnétique elements are not visible with normal viewing instruments (naked eye, optical magnifying devices, et cetera), since they are always covered by metal.
- the magnetic elements are visible only by means of suitable devices dedicated to the detection of magnetism, such as for example magnetic scanners or lenses with liquid magnetic ink inserted in vacuum. Disclosure of the invention
- the aim of the present invention is to provide a security element particularly for banknotes, security cards and the like, having magnetic elements in which the magnetic difference of the regions cannot be detected by normal instruments for detecting current magnetic codes provided on security threads.
- an object of the present invention is to provide a security element, particularly for banknotes, security cards and the like, in which said magnetic elements can be detected exclusively by means of dedicated sensors.
- Another object of the present invention is to provide a security element in which the magnetic elements have such differences as to generate different codes which can be detected even with devices whose feed rate is from one banknote per second up to at least 50 banknotes per second.
- Another object of the present invention is to provide a security element in which its counterfeiting is made even more difficult with respect to known types of security elements since only someone who knows the basic principle and the location of the areas can detect their content.
- Still another object of the present invention is to provide a security element which is highly reliable, relatively simple to provide and at competitive costs.
- a security element particularly for banknotes, security cards and the like, comprising a first substrate which is at least partially opaque when viewed in transmitted light, magnetic areas being deposited on said substrate, characterized in that said magnetic areas comprise at least two types of magnetic areas which have different coercivity values and whose residual magnetism is identical or different, said different values being adapted to generate at least three mutually different codes.
- Figure 1 is a plan view of a security element according to the present invention, with the optional second supporting layer removed, according to a first embodiment of the invention
- Figure 2 is a sectional view of the security element of Figure 1, with the second supporting layer present;
- Figures 3a, 3b and 3c are views of respective signals which can be obtained, and therefore of codes which can be obtained, by reading the security element according to Figures 1 and 2;
- Figure 4 is a plan view of a security element according to the present invention, with the optional second supporting layer removed, in accordance with a second embodiment of the invention;
- Figure 5 is a sectional view of the security element of Figure 4, with the second supporting layer present;
- Figures 6a, 6b and 6c are views of respective signals which can be obtained, and therefore of codes which can be obtained, by reading the security element according to Figures 4 and 5. Ways of carrying out the Invention
- the security element according to the present invention comprises a first substrate or first supporting layer 2 which is at least partially opaque when viewed in transmitted light and on which magnetic areas 3, 4 are deposited.
- the substrate 2 is conveniently made of plastics, such as polyester, and the opacity is provided by the presence of deposits of metal or inks with colors and/or pigments, or color-shifting materials or materials obtained from mixtures of such materials.
- the peculiarity of the invention consists in that the magnetic areas 3, 4 comprise at least two types of magnetic areas which have different coercivity values and whose residual magnetism is identical or different; the difference in coercivity and the identical or different residual magnetism are aimed at generating at least three different codes.
- the magnetic areas are provided by means of magnetic inks whose coercivity is different (for example 200 oe for the lowest and 3000 oe for the highest) and whose residual magnetism can be identical or different depending on the type of coding, equally when they are deposited sequentially, adjacently or superimposed.
- a sequence of nine magnetic areas 3, 4 spaced by 4 (and more than 4) mm of gap is printed onto a thread which is 2 mm wide, 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 areas have a coercivity of 300 oe.
- Figures 3a-3c plot respectively the signals which can be detected by a reading sensor, for a security element 1 according to the first embodiment of Figures 1 and 2, in which Figure 3 a plots the signals that can be detected from all the magnetic areas 3, 4, Figure 3b plots the signals that can be detected from the magnetic areas with high coercivity, and Figure 3 c plots the signals which can be detected from the magnetic areas with low coercivity.
- a security element such as a security thread
- This is achieved by using for example the same value of residual magnetism both for the areas 4 with low coercive power and for the areas 3 with high coercive power.
- Both inks with high coercive power and inks with low coercive power can be provided by means of mixtures of oxides or with a single type of oxide, all this being aimed at achieving the different significant coercivity.
- This overlap can occur for example by overprinting or, better still, by coupling in register two supporting or substrate layers 2, 5 in which respectively the first one contains the areas 3 with high coercive power and with a residual magnetism for example equal to 100 nW/m, with other areas 3 with high coercive power with a residual magnetism for example equal to 50 nW/m and the second supporting layer 5 contains areas 4 with low coercive power with a residual magnetism equal for example to 100 nW/m and 50 nW/m.
- the two layers 2, 5 are coupled in register, overlapping the 50 nW/m areas, one obtains a sequence of areas whose signals, oriented with a magnet with high coercive power and read by the first reading head, are a very similar sequence, the variation of which is caused only by the length of the areas and of the corresponding gap.
- Another example consists in using, for some areas, an ink with only 4000-oe pigment and, for the remaining areas, an ink with a mixture composed of 33% 4000-oe pigment and 66% pigment with a coercivity of 300 oe. In this manner, one obtains areas composed with the mixture which are preset to generate magnetic signals as a function of the strength of the magnet that is used, of the orientation of the flux and of the method of use.
- a security thread which is 2 mm wide, has a first supporting layer 2 made of plastics such as polyester, onto which a full surface of aluminum 10 is deposited by vacuum metalization in which, by means of a demetallization process, text and/or graphic markings are removed completely or partially, according to a preset graphic layout, considering the thickness of the aluminum.
- magnetic areas 3, 4, for example 2 mm long, spaced by spaces 10 without magnetic material for a length of for example 4 mm, are thus deposited between one text and the other.
- the magnetic areas 3 are provided by means of inks with high coercive power alternated with magnetic areas 4 with low coercive power; the residual magnetism of these areas is all identical with a tolerance given by the different production processes.
- This first supporting layer 2 is then coupled to an additional supporting layer 5 of polyester which is always metalized and demetallized, at least partially, in regions in order to leave free the areas where the text has been positioned so that they can be read in transmitted light.
- new magnetic areas 3 are printed with a different surface: one difference might be for example a 66% coverage of the area, arranging the magnetic material on the edges of the thread.
- the width of the thread which has been assumed to be for example 2 mm, is divided into three parts: one has a first area measuring 0.66 mm made of magnetic material, a space of 0.66 mm and a second area of 0.66 mm of magnetic material.
- the codes that are present on the thread can be detected with suitable sensors which are described hereinafter.
- This last type of thread therefore, has an additional characteristic, which consists in highlighting the presence of two additional areas only when the document is read transversely to the thread.
- the second areas 4, printed on the second supporting layer made of polyester 5, can also be overmolded directly onto the first areas 3 which are already present on the first supporting layer 2 made of polyester.
- the magnetic areas 3, 4 provided with different coercivities may have the same and/or a different residual magnetism determined by the different amount of magnetic material that is present for an equal area and thickness, or by the difference in thickness of the deposition for an equal area, or by oxides which have the same coercivity but different residual magnetism (oxides of different physical origin), or between mixtures of all of the above.
- Figures 6a, 6b, 6c plot, in a manner similar to Figures 3 a, 3 b and 3 c, the signals (codes) which can be detected by the security element provided according to the second embodiment of the invention.
- All the previously described threads provide for non-orientation of the magnetic direction of the magnetic ink during the transition from wet ink to dry ink which is characteristic of printing. Further customizations can be performed for example by orienting the iron oxide which is used for the areas 3 and therefore has a high coercive power during printing, when it is still wet, then overmolding or coupling in register the magnetic areas 4 with low coercive power.
- the magnetic areas 3 always have a north-south orientation, while the areas 4 can have a north-south or south-north orientation (180° rotation of magnetism) or are canceled out (for reading which is parallel to the thread), rotating the magnetism of the areas 4 only through 90°.
- the security elements thus provided detected by the sensors as described and therefore the three codes that exist in a single banknote, can be used for example by different devices intended for different operators, such as ordinary shopkeepers with the first code, commercial banks with the first and second codes, and central banks with all three codes.
- the security element according to the present invention can be for example a security thread or a security ribbon or stripe.
- the security element according to the present invention can comprise, on at least one of its sides, holographic and/or color-shifting and/or mono- or multifluorescent images.
- the materials used may be any according to requirements and to the state of the art.
