Description

Field of the invention

The The invention relates to a first security and / or value document a security element, wherein the security element at least two different security features selected from the Group consisting of "hologram, laser engraving, print motif, fluorescence motif, Luminescence motif, diffractive motif and Optical Variable Ink (OVI) motif " contains a method of producing such a safety and / or value document, as well as a method for validating a such security and / or value document.

Background of the invention and state of the art Technology.

security elements serve a security and / or value document against counterfeiting or Copy to backup. Typically, a security and / or Value document several different security elements and will only then accepted as valid if all security elements exist are.

A long known type of security feature is the printing technology made guilloche. This is a very fine Line pattern, which reproduces only under high technical pressure can be.

A Another type of security feature is by way of laser engraving produced. For this purpose, a security and / or value document a security feature layer with a material, which absorbs light of the wavelength of a laser, wherein which converted into heat upon absorption of the laser light Energy to decompose and / or discolour the material leads, which is visible with the eye. A laser beam can, for example, by means of a mirror arrangement on the security feature layer are driven, resulting in lines, To create patterns as well as surfaces. The laser engraving can also be done in a security feature layer, the Is covered by further layers, provided the other layers Do not or only slightly absorb the laser light.

Another type of security feature is the hologram. The production of a volume hologram is, for example, in the reference EP 0 896 260 A2 described. Embossed holograms are produced by imaging a holographic structure, for example by means of photographic processes, on a die, then subjecting the die to a chemical process, wherein the holographic structure is formed as a topography, and by means of the die, for example, in a plastic layer by pressure and / or or Temperatureinwirkung the holographic topography is transferred to the plastic layer.

A Another type of security feature is the luminescent motif. Here, a graphic structure by means of a luminescence (Fluorescence or phosphorescence) of competent substance. Excited with light, such as UV light, luminescent the substance and the motive become recognizable (if not without irradiation recognizable) or is recognizable as luminescent (if without irradiation recognizable, for example based on the color).

Out practice, for example, a 50, - Euro bill, is a security element known, with different layers Have security features, which register each other are positioned and connect their graphic structures together. These are those on the front left top in the transmitted light recognizable value "50". In reflected light are on both sides only to recognize complementary parts of the "50". Here are the Both security features with the same technology, namely the printing technique, manufactured.

For example, from the literature DE 39 32 505 C2 a security and / or value document of the aforementioned construction is known, wherein in the context of security features various techniques, such as holograms and laser engraving, are combined. For example, an individual character set is written into a hologram by laser engraving. The two security features are usually in one and the same layer and, moreover, always represent independent graphic structures.

With increased technical complexity are the extent known Security and / or value documents can be reproduced.

Technical problem of the invention

Of the The invention is therefore based on the technical problem of a security element specify a security and / or value document which does not or is replicable only under extreme technical effort.

definitions

The term of various security features refers to security features that are manufactured using different technologies. For example, all printing techniques for non-fluores Decorative inks are referred to as a technology. All printing techniques for fluorescent inks are also a technology (different from the above printing techniques). The same applies to all holography techniques. Various security features are, for example, the following combinations: hologram / print motif, hologram / fluorescence motif, hologram / laser engraving, print motif / laser engraving, print motif / fluorescence motif or laser engraving / fluorescent motif. Correspondingly, the same applies if three different security features are set up, then, for example, the combinations hologram / print motif / laser engraving, hologram / print motif / fluorescence motif, or print motif / laser engraving / fluorescence motif. In the case of four different security features, this would be, for example, the combination hologram / print motif / laser engraving / fluorescent motif.

One Security element is the combination of several different ones Security features formed.

When graphical structure are, for example, lines, characters, or surface patterns or parts thereof. In the case of the lines may be the line width be in the range of 0.001 mm to 1 mm, preferably it is in the range of 0.01 mm to 0.02 mm. For example, characters can be alphanumeric characters, such as numbers or letters. surface pattern are generally uniform flat constructs with defined shape, such as circle, rectangle, square, Ellipse, circle segment, ring, ring segment, etc ..

graphical Structures then form a graphic representation when the different security elements are each graphical structures, which in conjunction with each other is an overall graphical representation form. So can the different security elements be complementary to each other. For example, a first Security element a first part line and a second security element form a second partial line, both partial lines then due of the complementary relationship an overall line form. This can be done, for example, in the context of a line pattern, z. B. a guilloche pattern, be set up, in which case a first security element forms a first part of the line pattern and the second security element comprises a second part of the line pattern. Another example is the training complementary to each other Partial sign for various security elements, which together a character, such as a letter or a Make number. In these cases, close the graphic Structures against each other, of course, at least partially overlaps are possible, as well as with the human eye not immediately apparent gaps between the graphic Structures. An overall graphic representation finally includes the surface underlay of a line pattern or a Character. Then superimpose the different security features each other.

A overall graphical representation is a given graphical representation, resulting from the graphical structures of the various security features total results. The overall graphic representation forms the security element.

One Security element is a structural unit, which at least one Security feature includes. A security element can be a self-contained one be a structural unit with a security and / or value document connected, for example, glued, can be. It may be but also an integral part of a security and / or Act on the value document. An example of the former is, for example a holographic sticker. An example of the latter is one within the framework of a layered structure of a security and / or value document integrated layer with a security feature.

One Security and / or value document is typically constructed with a flat substrate, on one side or whose two sides have at least one layer, for example a printing layer, is applied. Come as materials for a substrate All customary materials on paper and / or plastic in question. The substrate is not necessarily one layer but can in turn consist of a plurality of layers, For example, films (laserable, non-laserable, opaque, inlay with chip, etc.). It can also be transparent or translucent, or a translucent or translucent one Have windows. In the case of a multi-layered substrate, the Connecting the different substrate layers together in the same Course as the connection with according to the invention on the substrate applied layers, for example, in a single lamination step.

A graphical structure or overall graphic representation is individualizing if it is different for different security and / or value documents of the same type. In this case subgroups may be formed for security and / or value documents of the same type, in which the graphical structure or overall graphical representation is the same and only differentiate between the subgroups. Examples of such graphical structures or graphical representations are representations of the name of the owner of a security and / or value document, the serial number of a security and / or value document ment, the domicile of a holder of a security and / or value document, etc.

A graphical structure or overall graphical representation is non-individualizing or static, if they are for all security and / or Value documents of the same type is the same. Examples of this are coats of arms, seals, insignia, guilloche patterns, currency, Nationality information, etc.

A graphical structure or overall graphical representation can only Machine-recognizable or machine-readable, or machine-recognizable or machine-readable and be recognizable by inspection. An example of the former is a barcode. An example for the latter is an alphanumeric string.

Two Layers of a security and / or value document are in register one above the other arranged when the graphical structures of various security features, which are arranged in different layers, a given Overall presentation result.

In the former case can work with a non-transparent substrate become. Should the security element (also) be visible in the review, so the substrate should be transparent below the security element or translucent or below the security element have transparent or translucent window. In case that the substrate is transparent or translucent or such a window may differ from the layer structure described above also be provided that the optional second intermediate layer, the second security feature layer and possibly a second cover layer on one of the first security feature layer opposite lying main surface of the substrate are arranged.

In the context of the invention, the first intermediate layer and / or the second intermediate layer and / or the cover layer may be composed of several partial layers.

A preferred variant of the invention is characterized in that the first security feature a laser engraving or a print motif and the second security feature is a hologram. It can the hologram will be selected from the group from "Volume Holograms, Embossed Holograms, Transparent Kinegram Overlay, Kinegrame and Zero Order Gratings. "The print motif can a line pattern, in particular a guilloche, or an alphanumeric Sign or part of it.

When Security and / or value documents are in question identity cards, Passports, ID cards, access cards, visas, tax stamps, Tickets, driving licenses, motor vehicle papers, banknotes, Checks, stamps, credit cards, chip cards and self-adhesive labels.

The The invention further relates to a method for producing a security and / or value document according to the invention with the following process steps: a) a substrate is optionally included coated on a first intermediate layer, b) on the substrate or the first intermediate layer becomes a first security feature layer applied, c) to the first intermediate layer or the first security feature layer Optionally, a second intermediate layer is applied, d) on the first security feature layer or the second intermediate layer a second security feature layer is applied, e) to the second security feature layer is optionally a cover layer applied, wherein the stages a) to e) simultaneously or sequentially can be executed, either a first Security feature already included in the stage b) in the first security feature layer or at step d) or e) subsequently in the first Security feature layer is introduced, and / or where either a second security feature already in the stage d) in the second Security feature layer is included or to the stage d) or e) then into the second security feature layer is introduced. This is the introduction of a Security feature after step d) or e), for example, a Laser engraving. It is then understood that the layer superimposed with the laser engraving Layers permeable to the light of the laser are.

in the It is within the scope of the process according to the invention important to note that the different stages of application layers and their connection with each other in one go, For example, by laminating the successive to the substrate laid layers. Of course, that too is Subsequent application and bonding of the layers possible.

in the individual exist different ways of execution the method according to the invention.

The first security feature can already be in stage b) in the first Security feature layer and the second security feature already in step d) may be contained in the second security feature layer. Then the second security feature layer in step d) becomes register-accurate, based on the first security feature layer applied. This can be done by that before the step d) the position and orientation of the first security feature on the security and / or value document by means of optical detection means are determined, wherein the optical Detection means with a control device for positioning the second security feature layer are connected, and wherein the control device in the step d) is driven with the proviso that will be the positioning of the second security feature layer register accurate. Optical detection means can For example, include a CCD camera. The control device recognizes Using the signals from the CCD camera, the position and orientation of the first security feature or its graphical structure in relation on the CCD camera and controls the control device, for example a robot arm, with coordinate signals.

However, the first security feature can also not be mounted in the first security feature layer in the step b) and the second security feature in the step d) in the second security feature layer. Then, following the step d) or e), the first security feature is introduced in register into the first security feature layer, for example by laser engraving. This can be done by subsequently determining the position and orientation of the second security feature, for example a hologram, on the security and / or value document by means of optical detection means following step d), wherein the optical detection means are provided with a control device for controlling means for Insertion of the first security feature are connected, and wherein the control device is then controlled with the proviso that the introduction of the first security feature in the first security feature layer is accurate register. In the case of laser engraving for introducing the first security feature, the control device then comprises, for example, a mirror system pivotable in two spatial dimensions with which the laser beam can be arbitrarily positioned within the main plane of the first security feature layer. Conversely, the second security feature in stage d) may not be in the second security feature Layer and the first security feature in the step b) be mounted in the first security feature layer, wherein subsequent to the step d) or e) the second security feature is introduced into the second security feature layer register. Then the above applies analogously.

The Finally, the invention relates to a method for verification a security and / or Value document, whereby first the presence of both the first security feature and the second security feature is tested, with a positive result of this test register-accurate positioning of the first security feature and the second security feature checked each other and if the result of the test is positive register-accurate positioning the security and / or value document is considered valid. The exam can be the simplest Trap by visual inspection. That's the way it is, for example recognizable, if with a counterfeiting by not register exact Positioning the two security feature lines of a Line pattern stages, gaps or kinks have. Of course This test can also be done by mechanical means, for example by means of a camera, in which case by a processor the measured patterns compared with the stored predetermined pattern becomes. If one of the two preceding tests is negative, Thus, the security and / or value document is rejected as invalid.

in the Within the scope of the invention, the first security feature and the second security feature individualizing or static be. Likewise, the first security feature can be individualizing and the second security feature be static, or vice versa.

in the The invention will be described below with reference to exemplary embodiments only illustrative figures explained in more detail. Show it:

1 in a cross section, the layer structure of a security and / or value document according to the invention in a first variant,

2 in a cross section, the layer structure of a security and / or value document according to the invention in a second variant,

3 : Supervision of a security and / or value document according to the invention,

4 : Supervision only on a second security feature layer of the object 3 .

5 Supervision only on a first security feature layer of the object 3 , and

6 : a, schematic representation of a device for registration or introduction of a graphic structure.

In the 1 one recognizes a security and / or value document with a substrate 2 on which a first intermediate layer 3 , a first security feature layer 4 , a second security feature layer 5 and a cover layer 6 are applied. The first security feature layer 4 contains as security feature a first graphical structure 7 , which has been produced by laser engraving. The second security feature layer 5 contains as a security feature a second graphical structure 8th , which is formed for example as a hologram. The production can be carried out by first producing the illustrated layer sequence and then the first graphic structure 7 is introduced by means of a laser in the first security feature layer. For this purpose, the second graphical structure is first 8th detected for example by means of a light source and a camera with defined illumination. The thus determined position of the second graphical structure 8th is used to control a laser, so that the first graphical structure 7 register accurate to the second graphical structure 8th into the first security feature layer 4 is introduced.

In the 2 a variant is shown, wherein the first security feature layer 4 with the laser engraving (or a print motif) directly on the substrate 2 is arranged. This is optionally followed by a second intermediate layer 9 at. This is the second security feature layer 5 arranged with the hologram. The production can take place in that the first graphical structure 7 with the application of the first security feature layer 4 (For example, as a print motif) or immediately thereafter (for example, as a laser engraving) is attached. Optionally, then, an optical detection of the position and orientation of the first graphical structure 7 take place and then the register-accurate application of the second security feature layer 5 with the hologram, for example by sticking.

A comparative consideration of 3 to 5 is the register-accurate stacking of the first security feature layer 4 and the second security feature layer 5 removable. In particular, it can be seen that the lines of the first graphical structure 7 and the second graphical structure 8th connect exactly to each other. The figures are also taken from a third graphic structure 10 and a fourth graphical structure 11 the former being a lettering arranged on a circle and the latter a ring segment surface having a ring width of at least the height of the lettering, which is centered in the longitudinal direction of the lettering, is. With the graphic structures 7 . 8th respectively. 10 . 11 is each a security element 12 educated.

In both cases, the human eye readily recognizes when the first security feature layer 4 and the second security feature layer 5 not exactly register one above the other, because then the lines have interruptions or kinks and the lettering is not centered in the ring surface. This makes it easy to recognize and reject counterfeits. Real security and / or value documents are immediately recognized and accepted as valid.

For intermediate layers 3 . 5 and / or cover layers 6 All standard materials are suitable. These are typically polymer materials which are transparent. Also the security feature layers 4 . 5 are in areas outside the graphic structures 7 . 8th . 10 . 11 usually transparent, at least in those areas in which a graphical structure of an underlying security feature layer 4 or the substrate 2 is arranged.

In the 6 If one recognizes a device for registration or introduction of a graphic structure 7 . 8th . 10 . 11 , One recognizes optical detection means 13 with which the substrate 2 with attached first and / or second security feature layer 4 . 5 is received, wherein in one of the security feature layers 4 . 5 a first graphical structure 7 is introduced, but the second security feature layer 5 with the second graphic structure 8th not yet applied (for example by sticking), or in an applied second security feature layer 6 the second graphical structure 8th not introduced (for example by laser engraving) is. With the optical detection means 13 becomes the first graphic structure 7 received and the generated electrical signal of a control device ( 14 ) for positioning the second security feature layer 5 or for incorporation of the second graphical structure 8th into the second security feature layer 5 fed. To this control device 14 are means 15 for applying the second security feature layer 5 or for incorporation of the second graphical structure 8th into the second security feature layer 5 connected and are driven in accordance with the electrical signals so that the first graphical structure 7 and the second graphical structure 8th register accurately mounted on the substrate.
