Definitions

  • a feature that is intended to prevent imitation, falsification, unauthorized production and/or to guarantee the authenticity and integrity of the object is referred to as a security feature.
  • a physical object that has such a feature is referred to as a security element.
  • Typical security elements are, for example, holograms, security threads, but also complete security documents or security document blanks.
  • security features and security elements For a class of security features and security elements, it is intended to be checked and/or verified optically, i.e. by means of a visual inspection, the capture of images and their evaluation and/or other optical methods. Different optical features can be used and/or checked for this purpose.
  • EP 2 384 901 A1 describes a substrate for the production of value documents, comprising a first layer with a first transmittance, which has at least one recess in the region of which the first layer has a second transmittance which is greater than the first transmittance, wherein an opaque layer is applied to a rear side and/or to a front side of the substrate, which has a third transmittance which is smaller than the second transmittance.
  • a substrate for the production of value documents comprising a first layer with a first transmittance, which has at least one recess in the region of which the first layer has a second transmittance which is greater than the first transmittance, wherein an opaque layer is applied to a rear side and/or to a front side of the substrate, which has a third transmittance which is smaller than the second transmittance.
  • US$4,710,614 describes a security document comprising a substrate containing at least one optical fiber, at least one end of which is flush with a surface of the substrate to enable authentication of the document by a test based on exposing the document to a source of electromagnetic radiation and simultaneously observing the radiation transmitted to both ends of the optical fiber.
  • the optical fiber has a transparent coating and is located within the substrate at a depth of at least one surface of the substrate that is not greater than the penetration depth of electromagnetic radiation into the substrate. The radiation that penetrates the substrate to the optical fiber is captured in the optical fiber and transmitted to at least one end where it is observed to authenticate the document.
  • the invention is therefore based on the object of creating a method for verifying security documents with a window area that is easy to verify but not easy to replicate.
  • the invention is based on the general idea of creating a volume area made of transparent material inside the security element, which on the one hand forms a volume area from the top to an opposite bottom of the security element body extending window area, but between the top and the opposite bottom side, has an extension in cross section in the interior that is larger than the cross-sectional areas of the window area of the top and bottom, which are designed to be flush with one another.
  • This makes it possible for light that passes through the window area to partially reach that area, referred to here as the window boom, which is covered translucently on the top and bottom, so that this transparent area is not visible in plan view.
  • the window area is covered during observation, so that no light inside the security element body can reach the window boom through the window area. If light is additionally or simultaneously irradiated through the window area, the window boom becomes even more prominent under suitable lighting and viewing directions, i.e. as a contrast difference in the security element body in the window boom area relative to the other non-transparent areas adjacent to the window area and/or the window boom area.
  • the window area is the area on a surface of the security element body through which it is possible to see through the security element body, through the transparent material inside to the opposite side. Areas where this is not possible are called non-transparent areas of the The non-transparent area under which the window boom, ie transparent material connected to the see-through window, is located is called the boom area.
  • a transparent material is a material which is clear in volume, possibly coloured, but through which an image can be projected according to geometric optics using light of at least one wavelength in the visible, i.e. human-perceptible, wavelength range.
  • imaging according to geometric optics is thus possible at least for light of some wavelengths in the visible wavelength range if the window region is clear and colored, or for all wavelengths of the visible wavelength range if the transparent material forming the window region is not colored.
  • the transmission of light through a material layer or through a body is the process of light passing through or penetrating the material layer or the body, whereby the light can be scattered in the material layer or the body in the sense of classical optics.
  • a method for producing a security element which comprises a security element body with a window region extending from a top to a bottom, which is made of transparent material and merges into a window boom, the transparent material of which is completely covered in a non-transparent manner towards the top and towards the bottom, comprising: providing a core layer which is non-transparent in at least one surface section; making a recess in the core layer within the non-transparent surface section so that the recess is enclosed all around by a non-transparent part of the surface section; inserting transparent material into the recess; covering a boom section of the recess towards the top and towards the bottom in a non-transparent manner and introducing heat in order to form the security element body.
  • the core layer itself can consist of a plastic material or can be a composite of several material layers into which, for example, other elements and security features are integrated.
  • a good and simple covering of the window boom on the top and/or on the bottom is achieved with an embodiment in which the window boom is covered on the top by an upper covering layer that is not transparent in volume and/or on the bottom by a lower covering layer that is not transparent in volume.
  • the covering layer here is a self-supporting layer before being connected to the core layer and the material of the window boom.
  • a pure printing layer made of ink or printing ink that is not independently load-bearing is not considered a covering layer within the meaning of the description here.
  • This manufacturing process ensures that the non-transparent material layers that border the window area all the way around, for example the upper cover layer and/or the lower cover layer, have the same recess cross-section as the window area of the core layer.
  • a good, secure connection is achieved to the transparent material of the window boom, which is initially introduced in such a way that it partially protrudes into the window area.
  • the core layer recess is expanded, not only the non-transparent material of the core layer but also that part of the transparent material of the boom section that protrudes beyond the boundary lines into the window area is removed from the window area, so that an optimal connection is created between the transparent material of the boom section and the transparent material located in the window area and inserted into it.
  • recesses are not made parallel to the surface normal of the respective layers, but at an angle. This makes it possible to ensure that inserted transparent material pieces, such as the cantilever insert or the window plug, are held in place despite gravity when they are joined together in the respective layers, whose surfaces are oriented parallel to the earth's surface, for example. This makes handling easier.
  • the transition section is that section of the window contour in which the transparent material of the window area merges into the window boom area.
  • the length of the transition section of the circumferential contour of the window area is preferably less than a quarter of the length of the entire circumferential contour of the window area.
  • the window boom area is not covered transparently at least on the top or bottom side in such a way that a minimum level of transmission for verification light exists, so that an area of increased brightness can be detected during verification by irradiating the window area with verification light.
  • a window boom is formed which consists of transparent material which merges into the transparent material 51 of the window region 25.
  • the window boom 60 which is located in the boom region 27 on the inside, is not transparently covered by the top side 21 or the bottom side 22. Therefore, the window boom 60 is only shown in dashed lines in this view, since it cannot be seen from either the top side 21 or the bottom side 22 when viewed from above due to the non-transparent cover.
  • the transmission in the boom region 27 is generally greater than in the rest of the non-transparent region 26. This is increased even further when light enters the window region 25 and partially passes through the transparent material 51 on the inside into the window boom 60.
  • Fig.2 is a schematic sectional view through the security element 1 according to Fig.1 shown.
  • the transparent material 51 in the window area 25, which merges into the window boom 60, is clearly visible. This is covered by an upper cover layer 70 to the top side 21 and by the lower cover layer 80 to the bottom side 22.
  • the boom area is therefore not immediately visible when looking at the security element 1.
  • the recesses 73 in the upper cover layer 70 and 83 in the lower cover layer 80 are identical to a window area 42 of the recess 40, which is however larger and additionally includes the boom section 41 in the core layer 30, which is non-transparent.
  • the core layer 30, the upper cover layer 100 and the lower cover layer 110 are therefore all three non-transparent.
  • the window 50 in the window area 25 and the boom 60 in the boom area 26, on the other hand, are made of transparent material.
  • the transparent material in the area of the boom 60 does not have to be identical to the transparent material of the window area 25. However, it is necessary that this material merges into one another without a gap. This allows light to pass from the window 50 into the window boom 60.
  • a transparent plastic material particularly preferably polycarbonate.
  • the core layer 30 and the upper cover layer 70 and the lower cover layer 80 are also preferably made of a plastic material, particularly preferably of the same material as the window 50 and the window boom 60. Polycarbonate is particularly preferred here.
  • Fig.3 is the schematic plan view of the underside of the security element 1 according to Fig. 1 and Fig. 2 shown.
  • the non-transparent area 26 can be seen, which covers the boom area and encloses and delimits the window area 25.
  • the underside 22 of the security element 1 is also non-transparent in the boom area 27.
  • FIG.5 A further embodiment of a security element is shown schematically. This differs from the embodiment according to Fig.4 in that the upper coating 100 for covering and the lower coating 110 for covering are each applied to a transparent upper protective layer 150 and a lower Protective layer 160 is applied.
  • the printing for forming one of the coatings 100, 110 on the upper or lower protective layer 150, 160 can be applied either on the side facing the core layer 30, as shown for the lower protective layer 160, or on the side facing away from the core layer 30, as shown for the upper protective layer 150.
  • the security elements 1 shown in the figures are preferably security document blanks which are combined with further layers to form a security document body. However, they can also be finished security documents.
  • an upper intermediate layer 180 and a lower intermediate layer 190 are joined to the core layer 30 and the information layer 90, with a non-transparent print 192 being applied to the lower intermediate layer 190, which precisely recesses the window area 25.
  • An upper protective layer 150 is provided on an upper side 21 and a lower protective layer 160 is provided on the lower side 22. All of these layers are heated in a final lamination step and combined to form a security element body.
  • a material layer that is not transparent in volume could also be provided below the core layer 30, into which a window recess is introduced at the same time as the extension of the recess 40 of the core layer and the introduction of the window recess 94 of the information layer, after this further layer has also been connected at certain points to the others before the formation of the recess.
  • the upper intermediate layer and the further lower intermediate layer can be omitted and an overprint of the cantilever area on the protective layer of the upper protective layer or the transparent insert can be carried out directly or towards the underside on the intermediate layer, the cantilever or the lower protective layer.
  • recesses in the various embodiments shown have side or boundary surfaces that are oriented perpendicular to the surfaces of the individual different layers, this is primarily due to a simplified representation.
  • recesses with vertically oriented side surfaces are possible embodiments, recesses that are designed with slanted, in particular tapered, side surfaces are preferred. This allows the preferably one-piece pieces of material intended to be inserted to fill the recess to be held optimally during production. These have correspondingly adapted slanted or also tapered side surfaces.
  • Verification light is then irradiated into the window area 210, the intensity of which is higher than the intensity of the ambient light, if any.
  • the irradiation occurs, for example, from the top. Alternatively, it could also occur from the bottom of the security element.
  • a verification decision is issued based on the classification 270. This can be used, for example, to control an access device.
  • An additional verification step can provide that the irradiation of the verification light during the capture of the at least one image or during the capture of a further image 300 takes place in such a way that a narrow strip of the area around the window region along at least one contour section of the window region is irradiated with the verification light.
  • the window contour is now examined 310 for brightness fluctuations outside a transition region from regions of increased brightness to the window region. If such fluctuations are found, this is an indication that the recesses of the core layer and covers, e.g. the cover layers, are not aligned.
  • a document is then also classified as not authentic in step 260 if such brightness fluctuations are found.
  • Additional tests can be included in the verification.
  • the same test can be carried out on both sides of the security element.
  • the verification can be carried out from one side, ie by shining the verification light and capturing at least one image from the same side of the security element.
  • This examination is particularly advantageous for detecting apparent forgeries that can simulate a similar effect in transmitted light. Only the examination of the contour of the window area is improved if this is designed in such a way that the light is emitted from the side opposite to the side from which the at least one image is captured.
  • Examining whether the contours of the various recesses that define the window section are correctly aligned with one another, possibly in different directions in certain sections, can be an independent or supplementary verification procedure. This verification can also be carried out using other optical means, such as a magnifying glass or a microscope.
