Definitions
- Security feature for a document of value for a document of value, document of value and method for producing a security feature
- the invention relates to a security feature for a document of value, a document of value and a method for producing a security feature.
- Documents of value or data carriers such as passport and ID documents, ID cards, credit cards, bank cards and the like are being used to an increasing extent in public areas, but also in the internal area.
- the object of the present invention is therefore to improve the presentation of these security features.
- the security feature is a combination of a positive and an image-processed positive of a single, ie the identical representation.
- a tilted image with this positive and the image-processed positive is easy to recognize because there is no color space change. Because the representation always remains positive, a tilting image with a smooth or flowing transition is created, which even allows verification with a standard card reader.
- the positive and the image processed positive can each be viewed as an identifier of the security feature. Both together can result in a flip image.
- the positive and the imaged positive can both be introduced through light-diffractive or light-refractive structures. Alternatively, one of the two can be introduced through the light-diffractive or refractive structures and the other can be introduced from a backside. This allows a combination of a viewing-angle-dependent marking introduced by a lens grid and a viewing-angle-independent marking introduced from a rear side.
- the changes in the optical properties of the recording layer or the security feature can be visible in transmitted and/or reflected light.
- the positive or the image-processed positive can be in a rastered form, wherein the raster elements can be formed by, for example, rod-shaped pixels.
- the positive or the image-processed positive also includes several identifiers such as individual numbers or letters, but also biometric features such as a portrait or a fingerprint.
- the security feature proposed here therefore has the advantage that simplified identifiability and/or verification of the authenticity of the security feature is made possible.
- the photoluminescence in the form of fluorescence or phosphorescence is considered here. For example, if white fluorescence is used, when viewed under a UV light, an effect can be achieved as if a light is switched on, or a beam of light is focused on the security feature. In this way, simpler and clearer recognition and identifiability as well as increased security against counterfeiting can be achieved.
- one of the positive or the retouched positive is a dynamic representation and the other is a static representation is.
- the static image or representation will be introduced from the side away from the lens, the dynamic image or representation from the lens side.
- the static image can be a main image.
- the positive and the image processed positive can each be a dynamic representation.
- both the positive and the image-processed positive are introduced via the light-diffracting or light-refracting structures.
- the two angles for inserting the positive or the image-processed positive can be offset by 90°.
- a marking is introduced at an angle of 90°, ie perpendicular to the light-diffracting or light-refracting structures. It can then be advantageous to increase the energy of a laser beam, for example.
- the contrast or image depth of the display can be changed using filters or image processing algorithms.
- the image-processed positive can thus be an overdrawn positive, for example.
- the imaged positive can be a relief representation of the positive.
- one of the positive or the image processed positive is a biometric representation and that the other is an outline of this biometric representation.
- the dynamic image can be the contour or outline of the main image, which can be a photo, for example, or vice versa.
- CLIP-ID as disclosed for example in DE 102018007207 B4, is also possible.
- personal data such as a signature, a date of birth, a portrait or the like.
- all elements that can be represented graphically can be represented from individual pixels that are activated by laser irradiation.
- all graphically displayable elements can be displayed from individual pixels, which are activated by laser radiation.
- a good optical representation and a smooth movement between the markings can be achieved by means of a lenticular grid with a number or multitude of individual lenses such as spherical lenses, rod lenses and/or cylindrical lenses.
- a document of value according to the invention such as a bank note, identity card or the like, comprises a substrate with an opening in which a data carrier as described above is at least partially arranged as a security element.
- the data carrier can be arranged completely in the opening.
- the opening with the data carrier located therein can be covered, for example, by means of one or more foils. Otherwise, the same advantages and modifications as previously described apply.
- a method according to the invention for producing a security feature comprises the steps:
- FIG. 2 shows a sectional representation of the document of value from FIG. 1 along the line II;
- Figs. 3 a basic representation of a security feature with a front side provided with a positive and with an image-processed positive and a negative back;
- Figs. 4 a basic representation of a security feature with a positive and with an image-processed positive
- Fig. 5 a method for producing a security feature for a document of value.
- FIG. 1 shows a plan view of a document of value 10 in a schematic representation.
- the document of value 10 can be a bank note, a passport and identification document or the like.
- the document of value 10 is an identity document.
- the document of value 10 contains a security feature 11 in the form of a portrait of the cardholder and other personal data 12 such as the First and last name of the holder.
- the ID card can contain additional data 13, such as date of birth, nationality, issuing authority, date of issue and the like.
- the security feature 11 is at least partially arranged in an opening 10a of the document of value 10 .
- a tilting image 14 is arranged in the security feature 11 in the form of a portrait of the document of value 10, which contains two different items of information or identifiers written by means of a laser beam in the form of a positive 19 of a representation and an image-processed positive 20 of the representation.
- the two identifiers are part of the security feature 11 or the two identifiers form the security feature 11.
- the two markings are not recognizable simultaneously when viewing the document of value 10, but only by tilting the document of value 10 at a different tilting angle in each case.
- FIG. 2 shows a section through the document of value 10 along the line I-I of FIG.
- the document of value 10 contains a transparent card body 15 and at least one, preferably two, laser-sensitive recording layers 16 and 17.
- the card body 15 can be transparent or partially transparent.
- the card body 15 can also be opaque, in which case a transparent or partially transparent window is provided in the area of the two laser-sensitive recording layers 16 and 17 .
- the recording layers 16 and 17, like the substrate or the card body 15, are transparent or partially transparent in the visible spectral range.
- the recording layers 16 and 17 can be a part of the card body 15 or separate layers.
- the document of value 10 here comprises a surface relief in the form of a lenticular grid 18 on an upper side or front side.
- the lenticular grid 18 is arranged above the recording layer 16 and can be arranged directly on the recording layer 16 .
- the recording layer 16 is thus located between the lenticular grid 18 and the recording layer 17.
- the surface relief in the form of the lenticular grid 18 can be arranged on an underside or rear side of the recording layers 16 and 17. Then the lenticular grid 18 is located inside the card body 15.
- a lenticular grid 18 with individual lenses such as spherical lenses, rod lenses and/or cylindrical lenses is used.
- lenses instead of the lenses, light-diffracting and/or light-refracting structures can also be used.
- a first identification in the form of a positive 19 of a representation is introduced into the recording layer 16, which can be referred to as the first recording layer.
- the recording layer 17 which can be referred to as the second recording layer, a second identification in the form of an image-processed positive 20 of the same representation is introduced.
- the two recording layers 16 and 17 run parallel to a main surface of the document of value 10 and can directly adjoin one another.
- the markings 19 and 20 introduced into the tilting image 14 contain personal information and are only written into the recording layers 16 and 17 after the lens grid 18 has been applied, for example by means of a pulsed infrared laser. This applies at least to the first marking 19 in the recording layer 16.
- the laser beam is directed onto the lenticular grid 18 from different directions 21 or 22 . Focus the individual lenses of the lens grid 18 the laser beam, depending on the direction of irradiation, onto different small sub-areas 23 or 24 of the recording layer 16.
- the effect of the laser radiation changes the optical properties of the recording layer 16 locally, for example the layer is locally blackened.
- the blackened sub-areas 23 can be seen precisely because of the focusing effect of the individual lenses, and they combine to form an image for the viewer.
- the partial areas 24 written from this direction can be seen from the viewing direction 22 and form an image for the viewer.
- the document of value 10 can comprise additional layers, for example one or more protective layers or functional layers provided with other security elements.
- the transparency of the document of value 10 in the area of the inscribed positive 19 and the inscribed image-processed positive 20 should be retained.
- the recording layer 17 is described similarly to the recording layer 16.
- the various partial areas 25 and 26 are arranged in the recording layer 17 in a matrix-like arrangement.
- the second indicia in the form of the imaged positive 20 is also inscribed in the recording layer 17 by means of a laser such as a pulsed infrared laser.
- the image processed positive 20 can be inscribed through the lenticular screen 18, for example from the direction 22.
- Both positives 19 and 20 are then dependent on the angle.
- the result is a tilted image from viewing directions 21 and 22.
- the underside is that side of the document of value 10 which is opposite the lenticular grid 18 . In this way, the image-processed positive 20 is introduced into the recording layer 17 undistorted.
- the viewing angle-dependent positive 19 of the recording layer 16 and the viewing angle-independent image-processed positive 20 of the recording layer 17. While, as described, the positive 19 is viewing angle-selective from one or the two directions 21 and 22 is recognizable, the image-processed positive 20 can be seen from all directions, including both directions 21 and 22.
- the two recording layers 16 and 17 are in the form of two recording layers. It is also possible to provide a single recording layer in which the positive 19 is written through the lenticular screen 18 and the image-processed positive 20 is written through the lenticular screen 18 or from the back.
- a luminescence substance can be introduced between the positive and the image-processed positive 20 .
- the substance is brought into an excited state by energy supplied from outside and emits light when it transitions to its ground state, emitting photons.
- the photoluminescence in the form of fluorescence or phosphorescence is considered here.
- the luminescent substance can be integrated either by printing or by means of a film or an insert, preferably as white fluorescence.
- the luminescent substance allows the information to be easily recognized by border officials or police officers, for example, during passport control or a driver's license check using a UV lamp.
- FIGS. 3 show a basic representation of a security feature 11 with a positive front side provided with a contour and a negative back side.
- the security feature 11 is shown with its front side, ie the positive 19.
- the positive 19 here includes a positive representation 28.
- the positive representation 28 consists of a large number of image points or pixels, which are introduced by means of a laser beam, as described above. Since the first identification drawing 19 was introduced by the lenticular grid, the first identification 19 is dependent on the viewing angle.
- FIG. 3b also shows a representation of the front of the security feature 11 with an image-processed positive 20 in the form of a contour 29 which surrounds the positive representation 28 from FIG. 3a.
- the positive representation 28 of the positive 19 shown in FIG. 3a can be shown from the viewing angle or the direction 21.
- the representation of FIG. 3b can be represented from the viewing angle or the direction 22.
- the positive representation 28 or the contour 29 is emphasized.
- FIG. 3c shows a view of an optional rear side of the security feature 11 or a third marking 31. In addition to the two positives 19, 20 on the front, the third marking 31 is on the back.
- the third marking 31 here includes a negative representation 30 of the positive representation 28 from FIG. 3a. Since the negative representation 30 of the third identification 31 was not applied by the lenticular screen, the third identification 31 is a static representation.
- the security feature 11 is formed by the positive depiction 28 and the contour 29 as well as the negative depiction 30 .
- FIGS. 4 show a basic representation of a security feature 11 with a positive front side provided with a contour.
- FIG. 4a shows a positive 19 with a positive depiction 28.
- the image-processed positive 20 with a contour 29 is shown in FIG.
- the positive outline 29 or relief corresponds to an overdrawn image of the positive 19 in which the contrast along the edges of the positive 19 is increased or enhanced.
- the positives 19 and 20 shown in Figures 4a and 4b are dependent on the viewing angle. Accordingly, the positive 19 is angle only from a certain point of view, for example the direction 21 recognizable.
- the image-processed positive 20, on the other hand, can be seen from a second viewing angle, such as direction 22. All combinations of the positive representation 28 and the contour 29 in the positive 19 and the image-processed positive 20 are possible. A combination with a color extract as a CLIP ID is also possible.
- the positive 19 and the image-processed positive 20 are shown as portrait representations or as parts thereof.
- One or both positives 19, 20 can include any personal data, such as a signature, a date of birth or the like.
- the positives 19 or 20 can include data relating to the document of value 10, such as a period of validity, a card number, information about the issuing authority or the like.
- Figure 5 shows a method for producing a security feature 11 for a document of value 10.
- At least one laser-sensitive recording layer 16, 17 that is transparent in the visible spectral range is provided with a surface relief in the form of a lenticular grid 18 on a first side of the recording layer 16.
- a positive 19 of a representation 28 such as a portrait is provided.
- an image-processed positive 20 of the representation 28 is provided by image processing of the representation 28, such as, for example, increasing the contrast, so that an outline or a relief of the representation 28 arises.
- one of the positive 19 or the image-processed positive 20 is introduced with a laser beam from a first direction 21 through the lenticular grid 18 into the at least one recording layer 16, 17, so that one of the positive 19 or the retouched positive 20 at the later viewing of the security feature 11 from the first direction 21 is recognizable bar
- a fifth step 140 the other of the positive 19 or the image-processed positive 20 is introduced with a laser beam from a second direction 22 into the at least one recording layer 16, 17, so that the other of the positive 19 or the image-processed positive 20 is recognizable when the security feature 11 is viewed from the second direction 22 later.
- the order of the steps is not necessarily restricted to this order.
- the provision of one or both positives 19, 20 can also take place as a first or second step.
