Description

The invention relates to a value document.

A value document within the meaning of the invention can be banknotes, identification documents, check cards or credit cards, but also stocks, certificates, postage stamps, checks, admission tickets, tickets, air tickets, ID cards, visa stickers or the like, as well as labels, seals, packaging or others Elements. The simplifying term “document of value” therefore always includes documents of the type mentioned in the following. The term value document also includes security paper for the production of bank notes.

It is known from the prior art to equip value documents with security elements, such as security strips or security threads, which contain a code. For example A magnetic coding with a sequence of magnetic and non-magnetic areas can be provided as coding of a security thread, the sequence being characteristic of the type of document of value to be secured. It is also known to use different magnetic materials for magnetic coding, for example with different coercive field strengths.

For example, two different coercive magnetic materials can be used as the magnetic coding, from which two types of magnetic bits are formed. Along the magnetic coding, the different coercive magnetic bits are usually separated from one another, e.g. separated from one another by non-magnetic material.

The DE 10 2007 025 939 A1 describes a security element with a magnetic coding which has at least one first coding element and at least one second coding element. The first and second coding elements are arranged on or in the security element along a predetermined direction. The first coding element has a first magnetic area with a first coercive field strength continuously along the predetermined direction, the second coding element contains a first gap area and a second magnetic area with a second coercive field strength that differs from the first coercive field strength. The first magnetic area is arranged directly adjacent to the second magnetic area along the predetermined direction. In addition, the lengths of the first and second magnetic areas are selected such that the sum of the lengths of the first and second magnetic areas along the predetermined direction is a maximum of 8 mm. Such a magnetic coding can even then can be reliably detected by the magnetic sensor when the security element is transported along the magnetic coding.

The EP 1 567 714 B1 describes a method for the precisely registered introduction and positioning of elongated security elements in a value document substrate.

The EP 2886362-A1 discloses a document of value, in particular a bank note, with a visually and machine-readable individualizing identifier, which is formed from alphanumeric characters, and with a machine-readable checking element. The individualizing identifier has a machine-readable coding and the checking element contains the type of coding for verifying the authenticity of the individualizing identifier in a coded form.

Other examples of documents of value with machine-readable codes are from US 2002 / 130186- A1 , WO 2016/037895-A1 and GB 2318089-A known.
The invention is based on the object of providing a document of value with a machine-readable coding, the document of value being improved in terms of its authenticity in terms of its verifiability.

This object is achieved by the combination of features defined in claim 1. Further developments are the subject of the independent claims and the subclaims.

Detailed description of the invention

The value document according to the present invention comprises a value document substrate with a value document substrate control feature and an elongated security element introduced into the value document substrate with a security element control feature, the security element extending from one end of the value document substrate to another end of the value document substrate and thus introduced into the value document is that the security element control feature is aligned with the value document substrate control feature, and the security element has precisely one long magnetic code which extends essentially over the entire length of the elongated security element introduced into the value document substrate. The value document thus has exactly one long magnetic code, i.e. the magnetic code contains only one code length and no repetitive, repetitive code sequences. In this way, a high information content can be provided for each value document. In addition, the magnetic coding can be detected by the magnetic sensor with high reliability.

The production of an endless paper web for security and value documents by means of a cylinder mold paper machine is known in the prior art, see e.g. Helmut Kipphan, "Handbuch der Printmedien", Springer Verlag, 2000, pages 124-127 .

A method for precisely registering elongated security elements in value document substrates is disclosed in US Pat EP 1 567 714 B1 known. The method is based on the use of a value document substrate control feature and a security element control feature. When the elongated security element is embedded in the paper substrate, the relative position of the two control features to one another is monitored. By controlling the tension of the elongated security element when it is introduced into the value document substrate using the position information, the speed at which the elongate security element is introduced can be regulated so that the control feature of the elongate security element is aligned with the control feature of the value document substrate, ie positioned in precise register is. A watermark mark, for example, can serve as the value document substrate control feature. Alternative value document substrate control features, for example inkjet marks, are, for example, from the EP 2 496 504 B1 known. By means of the method for precisely registering elongated security elements, a document of value can be produced with exactly one magnetic code, the magnetic code essentially extending from one end of the document of value to another end of the document of value and being positioned precisely in register in the document of value.

Furthermore, in a preferred embodiment, individual documents of value can be equipped with different magnetic codes. It is thus possible, during the production of the paper web by means of a cylinder mold paper machine, to embed several different security threads or security strips, which are arranged parallel to the running direction or longitudinal direction of the paper web and each have a different magnetic code, in the resulting paper web will. In the case of four different security threads arranged in parallel, each in the form of a continuous thread and embedded in the paper web emerging on the cylinder mold at the same time, paper sheets with four columns would result, each column of which has a special security thread with a special magnetic code.

According to the invention, the magnetic code of the elongated security element introduced into the value document substrate is related to a further machine-readable feature of the value document. Thus, the magnetic code of the elongated security element introduced into the value document substrate can be the first component and the further machine-readable feature of the value document, e.g. a luminescent or magnetic print motif produced on the paper, the second component of a combined code formed by the first component and the second component represent. So it is possible that when producing the paper web by means of a cylinder mold paper machine, several different security threads or security strips, which are arranged parallel to the running direction or longitudinal direction of the paper web and each have a different magnetic code, are embedded in the resulting paper web. In the case of four different security threads arranged in parallel, each in the form of a continuous thread and embedded in the paper web emerging on the cylinder mold at the same time, paper sheets with four columns would result, each column of which has a special security thread with a special magnetic code. The resulting paper sheets with four columns would later be provided with luminescent or magnetic print motifs. In the event that everyone single sheet of paper has five lines with differing luminescent or magnetic print motifs, 20 different value documents would be obtained per sheet of paper, which differ from one another in terms of the combined code (in plain language: a sheet of paper with four columns with different Contains security threads and five lines in the transverse direction with different print motifs).

The magnetic code can have a sequence of magnetic and non-magnetic areas. It is preferred to use different magnetic materials, for example with different coercive field strengths. For example, two different coercive magnetic materials can be used from which two types of magnetic bits are formed. Along the magnetic coding, the differently coercive magnetic bits can in particular be arranged at a distance from one another, e.g. separated from one another by non-magnetic material.

Security elements with magnetic codings based on different magnetic materials are, for example, from DE 10 2007 025 939 A1 , of the WO 2006042667 A1 , of the WO 2010113192 A1 and the WO 2012000568 A1 known. The magnetic code is preferably based on at least two different magnetic materials that differ with regard to at least one magnetic property. In particular, it is preferred that the two different magnetic materials have different coercivity values and the remanence values are identical or different.

The elongated security element introduced into the value document substrate is in the form of a security thread or a security strip. Furthermore, the elongated security element can be completely embedded or partially embedded in the value document substrate, which is preferably a paper substrate. For example, the elongated security element can be a completely embedded security thread, a window thread or a double-sided window thread. A window thread comes up to one side of the surface of the substrate, a double-sided thread comes up to the surface of the substrate on both sides. An embedded thread, on the other hand, is located within the substrate and, although it does not reach the surface of the substrate, it can span recesses, for example a hole, in a substrate. Embedded threads, for example, are made of EP 1 141 480 A1 and window threads and double-sided threads, for example EP 1 854 641 A2 , WO 2003/068525 A1 or WO 2003/070482 A1 known. A special case of the two-sided window thread is also referred to as a see-through window thread, which is clearly visible from both sides of the security element at the same time. A see-through window thread spans, so to speak, a hole or a translucent area in a substrate. Another two-sided window thread is a so-called alternating window thread, which is alternately clearly visible on the front and back of a substrate.

The long magnetic code can preferably extend over the elongated security element introduced into the value document substrate in such a way that the magnetic code is at a distance of at least 2.5 mm, preferably at least 5 mm, from the respective ends of the value document substrate.

The length of the magnetic code of the security element is at least 75%, preferably at least 80%, particularly preferably at least 85%, based on the length of the security element extending from one end to the other end of the value document substrate. In the event that the value document, for example a bank note, has a longitudinal direction and a transverse direction, it is preferred that the elongated security element introduced into the value document substrate extends along the transverse direction of the value document.

The invention provides that the magnetic code of the elongated security element introduced into the value document substrate is related to a further machine-readable feature of the value document. The magnetic code of the elongated security element introduced into the value document substrate represents the first component and the further machine-readable feature of the value document represents the second component of a combined code formed by the first component and the second component and possibly by a further component Document of value can for example be a luminescent feature, a magnetic feature, a feature obtainable by printing technology, an opening or perforation in the document of value substrate or a motif in the form of openings or perforations formed in the document of value substrate. Furthermore, the further machine-readable feature of the document of value can be generated, for example, by printing the document of value substrate, for example with luminescent or magnetic ink. In particular, the further machine-readable feature of the value document can be by means of Intaglio printing can be generated. In the event that the value document substrate is a If the substrate is paper, the paper itself is printed on. According to an alternative, the further machine-readable feature of the document of value can be part of a, for example patch-shaped or strip-shaped, film element applied to the document of value substrate and produced on the film element, for example by means of printing, in particular with luminescent or magnetic paint. Magnetic (printing) ink can, for example, be based on iron oxide or on another material based on iron, nickel or cobalt. Ferrites, for example barium ferrite, and alloys, for example AlNiCo or NdFeCo, are also suitable. Hard and soft magnetic materials can also be used, or materials with high or low coercivity. Transparent magnetic colors, like those in the scriptures GB 2387812 A and GB 2387813 A colors described can also be used. In addition, magnetically alignable magnetic pigments can be used to generate the further machine-readable feature of the value document. Such magnetic inks are, for example, from WO 2005/002866 A , of the WO 2008/046702 A and the WO 2002/090002 A known. A method for magnetically aligning a printing layer with orientable magnetic pigments is disclosed, for example, in US Pat EP 2792497 A1 described. Suitable printing inks are available, for example, under the trade name “SPARK” from SICPA Holding SA, Switzerland. Many of these colors use magnetic optically variable pigments called OVMI pigments. Such pigments lead to a different appearance depending on the viewing angle.

The elongated security element introduced into the value document substrate has, in addition to the long magnetic code, a further, separately machine-readable feature, for example a luminescent feature. The further, separately machine-readable feature of the elongated Security element can be formed, for example, by a security feature produced by printing and / or holographic technology. It can advantageously contain identification elements such as characters, symbols, text or even patterns. Furthermore, in particular, the further, machine-readable feature, for example, by an element or by several elements selected from the group consisting of a hologram, a laser engraving, a print motif, a fluorescence motif, a luminescence motif, a diffractive motif and an optically variable motif be educated. In particular, the further, separately machine-readable feature can be a diffraction structure, such as a (volume) hologram, or a hologram-like diffraction structure, a matt structure, a metallization, whereby several different colored metals can also be used, a perforation, a lens or micromirror structure , a micro-optical system, in particular a micro-optical moiré magnification arrangement, a thin-film element, a polarization filter or an imprint which has at least one substance with optically variable or luminescent properties. Suitable substances with optically variable properties are, for example, effect pigments, in particular pigments produced on the basis of liquid crystalline polymers or so-called pearlescent pigments, such as the silver-white, gold-luster or metallic luster pigments sold by Merck KGaA under the name Iriodin® or Colorcrypt. Furthermore, interference layer pigments are suitable as substances with optically variable properties. Interference layer pigments typically have a thin layer structure which expediently contains at least one reflective layer, an absorber layer and a dielectric spacer layer arranged between the reflective layer and the absorber layer.

The value document substrate control feature is formed by a watermark, by an opening in the value document substrate, by a feature obtainable by printing technology or by a feature in the form of a hologram. A control feature generated by printing technology can be measured, for example, in an opto-electronic way. With suitable sensor or measuring systems known in the prior art, very small control features can be recognized. In some cases, they are only a fraction of a square millimeter, so that they can hardly be seen in the printed image, i.e. they hardly disturb or are easy to arrange. In particular, the value document substrate control feature can be formed by a magnetic material. Magnetic printing ink can, for example, be based on iron oxide or on another material based on iron, nickel or cobalt. Ferrites, for example barium ferrite, and alloys, for example AlNiCo or NdFeCo, are also suitable. Hard and soft magnetic materials can also be used, or materials with high or low coercivity. Transparent magnetic colors, like those in the scriptures GB 2387812 A and GB 2387813 A colors described can also be used.

The security element control feature is metallic information, information in the form of a recess within a metallization, a motif in the form of a hologram, an electronic chip, a magnetic feature, a luminescent feature, a printing technology obtainable feature, formed by a photochromic or thermochromic feature or by an optically variable feature.

The value document substrate is preferably a paper substrate or a paper-like substrate, for example a plastic substrate or a film / paper / film composite or a paper / foil / paper composite. Any type of paper can be used as paper, in particular paper made of cotton. Of course, paper can also be used which contains a proportion x polymeric material in the range from 0 <x <100.

The at least partial embedding of the elongated security element in the substrate is advantageously carried out by means of the EP 1 567 714 B1 described cylinder mold paper machine. The elongated security element to be embedded in the substrate arises here from a thread material which comprises a multiplicity of elongated security elements in the form of repeating units. The thread material is in a state stored on rollers. The elongate security element is embedded by means of a variable braking device which slows down the unwinding speed of the roll on which the elongate security element is wound and thus controls the tension of the elongate element as it is introduced into the substrate. Via the tension of the elongated security element when it is being introduced into the substrate, the speed at which the elongated security element is introduced into the substrate is controlled in such a way that the control feature of the elongate security element is aligned with the control feature of the substrate.

Further exemplary embodiments and advantages of the invention are explained below with reference to the schematically greatly simplified figures, the representation of which has not been reproduced true to scale and proportion in order to increase the clarity.

Figure 1 illustrates a document of value not according to the invention, in the present case a bank note.

The bank note 1 is based on a paper substrate 2 which has a watermark 3 in the form of the denomination “20”. A security thread 4 is completely embedded in the paper substrate 2, ie the security thread 4 is barely recognizable to the viewer from the front of the banknote as well as from the back of the banknote when viewed in incident light, but recognizable when viewed in transmitted light. The banknote 1 has a dimension "A" of 7.2 cm in the transverse direction. The completely embedded security thread 4 has a magnetic code 5 with a length "B" of 6.2 cm. The magnetic code 5 is based on two different magnetic materials which have different coercivity values, the remanence values being identical. Of the Security thread 4 was created in accordance with the EP 1 567 714 B1 Known methods registered in the paper substrate 2, ie the security thread 4 and its magnetic code 5 are positioned in the bank note 1 in register. The distance between the end of the magnetic code 5 and the edge of the bank note paper is in each case 0.5 cm, ie the magnetic code 5 is introduced in the middle of the bank note 1. When the elongated security element 4 was embedded in the paper substrate 2, the relative position of the value document substrate control feature 3, namely the watermark "20", to the security element control feature, in the present case the magnetic code 5, was monitored. By controlling the tension of the elongated security element, which is present in the form of a continuous thread during the manufacture of the banknote paper, when it is introduced into the value document substrate using the position information, the speed at which the elongated security element is introduced can be regulated so that the control feature of the elongated security element is aligned with the control feature of the value document substrate, ie is positioned in precise register. The security element 4 thus has exactly one long magnetic code 5, which extends, in register, essentially over the entire length of the elongated security element 4 introduced into the bank note 1. The magnetic code 5 contains only one code length and no repetitive, repetitive code sequences. In this way, a high information content can be provided for the bank note 1. In addition, the magnetic coding 5 can be detected by the magnetic sensor with high reliability.

Figure 2 illustrates a value document according to the invention, in the present case a bank note, according to a first Embodiment. The one in the Figure 2 Banknote 1 shown has in addition to that in FIG Figure 1 The banknote shown has a security strip 6 based on a carrier film. The security strip 6 is applied to the paper substrate 2 of the bank note 1 by means of an adhesive layer and has a film security element, for example a hologram, on its surface. The hologram can be produced, for example, by metallizing the embossed relief structure of a UV lacquer layer. In addition, the security strip contains a machine-readable feature in area 7, which in the present case is produced by a magnetic material. The magnetic feature 7 of the security strip 6 can, for example, be obtained by printing technology, either (alternative 1) during the production of the security strip 6 or (alternative 2) only after the security strip 6 has been applied to the paper substrate 2 by printing the security strip 6 applied to the banknote 1 with magnetic paint. The magnetic feature 7 of the security strip 6 can, for example, be in the form of a character and, together with the magnetic code 5 of the security thread 4, represent a combined code. In the present case, the security strip 6 has a width of 1.6 cm and, according to a special variant, can span a hole or window formed in the paper substrate 2.

Figure 3 illustrates a value document according to the invention, in the present case a bank note, according to a second exemplary embodiment.

The one in the Figure 3 Banknote 1 shown has in addition to that in FIG Figure 1 The bank note shown has a printed area 8 produced by means of screen printing and / or intaglio printing. The printed area 8 is visually perceptible to the viewer. The printed area 8 also contains a machine-readable feature in a special area 9, which in the present case is produced by a magnetic material. The magnetic feature 9 is based on transparent magnetic paint. The area 9 is therefore not visually recognizable for the viewer. The magnetic feature 9 can, for example, be in the form of a character and, together with the magnetic code 5 of the security thread 4, represent a combined code.

As an alternative to the above example, the magnetic feature 9 could of course also be generated by means of a magnetic color that is visually perceptible to the observer, e.g. with a magnetically orientable SPARK color. Such a color is based on magnetic, optically variable pigments, so-called OVMI pigments. Such pigments lead to a different appearance depending on the viewing angle.

Figure 4 illustrates a value document according to the invention, in the present case a bank note, according to a further exemplary embodiment.

The one in the Figure 4 Banknote 1 shown has in addition to that in FIG Figure 1 The bank note shown has a security patch 10 based on a carrier film. The security patch 10 is applied to the paper substrate 2 of the bank note 1 by means of an adhesive layer and has a film security element, for example a hologram, on its surface. The hologram can be produced, for example, by metallizing the embossed relief structure of a UV lacquer layer. In addition, the security patch 10 contains a machine-readable feature in the area 11, which in the present case is produced by a magnetic material. The magnetic feature 11 of the security patch 10 can, for example, be obtained by printing, either (alternative 1) during the production of the security patch 10 or (alternative 2) only after the security patch 10 has been applied to the paper substrate 2 by printing the one applied to the banknote 1 Security patch 10 with magnetic paint. The magnetic feature 11 of the security patch 10 can, for example, be in the form of a character and, together with the magnetic code 5 of the security thread 4, represent a combined code. According to a special variant, the security patch 10 can span a hole or window formed in the paper substrate 2.

Figures 5 and 6th illustrate an example for the production of documents of value according to the invention.

The Figure 5 shows an endless paper web 12 for the production of banknotes. The endless paper web 12 is subdivided _{into a plurality of identical sheets of paper 13 n-1} , 13 _n , 13 _{n + 1} extending transversely to the endless longitudinal direction "L".

In the production of the paper web 12 was according to the from EP 2496504 B1 At least one watermark mark 20 and one inkjet mark 21 are applied to each sheet of paper adjacent to known methods. The watermark mark 20 and the inkjet mark 21 are not absolutely necessary, but can be used with advantage for (for example, register-accurate) control of further processing steps.

Each sheet of paper 13 contains a plurality of individual copies 14 which, in the exemplary embodiment, correspond to the later cut bank notes. The individual copies 14 each have a watermark in the form of the denomination “20”. The watermarks 15, as well as the watermarks 20, are available in the course of the cylinder mold technology.

The endless paper web 12 has four different endless threads 16, 17, 18 and 19 which differ from one another at least with regard to their magnetic coding. The continuous threads 16,17,18 and 19 are made by means of the EP 1567714 B1 known method embedded in the paper web 12 in precise register. When embedding the continuous threads 16, 17, 18 and 19 in the paper substrate 12, the relative position of the control features 15, namely the watermark "20", to the security element control feature, in the present case the magnetic code of the continuous threads, was monitored. By controlling the tension of the continuous thread when it is introduced into the paper substrate using the position information, the speed at which the thread is introduced can be regulated so that the control feature of the thread is aligned with the control feature of the value document substrate, ie positioned in perfect register. Each individual use 14 thus has exactly one long magnetic code which extends, in register, essentially over the entire length of the elongated security element introduced into the individual use 14.

In a subsequent step, the individual sheets of paper 13 are cut from the endless paper web 12 obtained.

Figure 6 shows a single sheet of paper 13 with a plurality of individual copies 14 which correspond to the later cut bank notes. The paper sheets 13 contains single copies in the form of four columns and five lines. With regard to the four columns, the individual benefits differ with regard to the magnetic coding of the embedded security threads 16, 17, 18 and 19 (in the Figure 6 the different magnetic coding is illustrated by means of different dashed lines).

The sheet of paper 13 was additionally printed with a transparent magnetic ink in the form of letters 26, 27, 28, 29 and 30 by means of screen printing and / or intaglio printing, the individual uses differing from one another with regard to the five lines in the type of letter: the Individual copies in the top line each have a magnetic print in the form of the letter "A"; the individual copies in the second line each have a magnetic print in the form of the letter "B"; the individual copies in the third line each have a magnetic print in the form of the letter "C"; the individual copies in the fourth line each have a magnetic print in the form of the letter "D"; the individual copies in the fifth line each have a magnetic print in the form of the letter "E".

The one in the Figure 6 The individual uses 14 shown can be distinguished from one another by machine by means of the combined code formed by the transparent magnetic print on the one hand and by the magnetic coding of the security thread on the other hand.

Using the in the Figure 6 A forgery attempt can be effectively prevented by embedding a real security thread in a counterfeit banknote paper. The code of the security thread of a bank note is related to the code of the bank note paper both spatially (ie the relative position on the bank note) and in terms of content (ie with regard to the information content).

There in the Figure 6 Both the code of the security thread and the code of the security paper are made magnetic, the check can be carried out in a simple manner by means of a magnetic sensor.

The magnetic features 7, 9, 11, 26, 27, 28, 29 and 30 mentioned in the above exemplary embodiments can of course be replaced by other machine-recognizable features, for example luminescent features. Luminescent features can be detected by machine in particular in the IR or UV range.

Furthermore, the elongated security element 4, 16, 17, 18 and 19 described in the above exemplary embodiments does not necessarily have to be completely embedded in the value document substrate, but it can just as well be partially embedded. For example, the elongated security element can be a window thread or a double-sided window thread. A window thread comes up to the surface of the substrate on one side, a double-sided thread steps up to the surface of the substrate on both sides.

In addition, the value document substrate is not limited to paper.

The magnetic code of the security thread can of course be generated with just one magnetic material, e.g. through the spacing and lengths of magnetic bits. At least one other magnetic material, e.g. with a different coercive field strength, can be used to advantage in order to generate further codes and to increase the complexity.

The machine-readable feature of the value document can also be formed on the front and / or the back of the value document. The application of the machine-readable feature (for example with luminescent or magnetic paint) both on the front and on the back of the document of value, for example by means of a Super simultaneous printing machine, enables the generation of further combined codes in which the information on the front and the information on the back are related to a specific spatial and / or content-related relationship. Machine-readable combined codes that are applied on both sides, ie both on the front and on the back of a value document, are, for example, from the EP 2 545 489 B1 known.

Furthermore, the function of the value document substrate control feature was taken over in the above exemplary embodiments by the watermark “20” (reference numbers 3, 15). The function of the value document substrate control feature could, however, also be taken over by another machine-readable feature, e.g. through an opening or a perforation in the value document substrate, through a printing technology-available feature, through a feature in the form of a hologram, through a luminescent feature or through a magnetic feature .

In addition, the presence of the value document substrate control feature 3, 15 within the area of the individual use 1, 14 (ie the bank note) is merely preferred. The value document substrate control feature could alternatively be arranged outside the individual uses 1, 14. For example, those in the Figure 5 watermark marks 20 shown and / or inkjet marks 21, which are produced adjacent to each sheet of paper 13 and outside the areas of the individual uses 14, also serve as value document substrate control features.
