Definitions
- the invention generally relates to banknotes.
- Banknotes are documents of value that embody value. They are issued by banks, especially central banks, and serve as legal tender.
- the invention further relates to the production of a series of banknotes in which banknotes of the same value are designed in the same way.
- Banknotes are made from a flat substrate and have a graphic design, in particular printed, on both surfaces.
- banknotes are provided with a variety of security features. These include, for example, a security print, e.g. B. in the form of one or more guilloches, or are using special printing processes, e.g. B. intaglio printing, or special printing inks, e.g. B. optically variable colors (OVI - English Optical Variable Ink), which change their color impression depending on an illumination direction and / or a viewing / detection direction.
- a security print e.g. B. in the form of one or more guilloches
- special printing processes e.g. B. intaglio printing
- special printing inks e.g. B. optically variable colors (OVI - English Optical Variable Ink)
- the composition and design of the substrate which is referred to as banknote paper, is also a security feature, even if the substrate is often not paper in the strict sense, but a fiber or fiber composite, for example based on cotton fiber.
- the substrate can be one or more layers and made of different materials.
- the invention is therefore based on the technical task of creating banknotes that have novel security features that enable good differentiation and at the same time also enable verification.
- a banknote comprising a flat substrate element, wherein the substrate element has a plurality of folds, so that a three-dimensional body can be created when the substrate element is folded along the folds.
- banknotes are produced in series, i.e. H. Similar banknotes, which embody the same value, for example, are designed similarly in such a way that the formation of a three-dimensional body by means of folds leads to the same shape of the three-dimensional body.
- a fold is a material taper or change that promotes and facilitates folding of the substrate element along the fold compared to folding of the substrate element elsewhere.
- banknotes with a flat substrate element, which enable a user to fold this substrate element for verification purposes and thereby form a three-dimensional body. If the folds are arranged in such a way that a three-dimensional body can be formed when folded along the folds, the banknote is verified as genuine.
- the banknotes When originally manufactured, the banknotes are flat and stackable.
- the plurality of folds are preferably introduced into the material of the substrate elements by pressing or embossing plates. In some embodiments, material removal may also occur when forming the folds.
- banknotes produced in series are similar in terms of the folds formed.
- the presence of the folds and their precise arrangement and design can also be used individually or in combination as a security feature for verification.
- the production can be done in single use or multiple use.
- At least one fold is designed to be selective in the folding direction. This means that the fold favors folding in one folding direction over another folding direction. If you look at a flat substrate, for example a sheet of paper, from one side, it is possible to fold the sides facing the viewer onto each other along a fold, which is one represents the folding direction, or to fold the sides facing away from the viewer along the fold, which represents the other folding direction. A fold can now be formed in some materials such as paper in such a way that it promotes folding in one folding direction over the other folding direction or vice versa.
- the plurality of folds include fold direction-selective folds for both fold directions.
- the folds can be designed for Platonic solids. These Platonic solids can only be produced by folding a flat substrate element with a rectangular base. The surface elements of the three-dimensional Platonic solid themselves have no folding edges. The three-dimensional Platonic solids are also stable without adhesives such as glue.
- the parts of the substrate element that are delimited by folds and/or outer edges of the substrate element are referred to as surface elements.
- Surface elements that form an outer surface of the three-dimensional body are called body surface elements.
- Each surface element has surface portions formed on its opposing surfaces, which are portions of the opposing surfaces of the substrate element.
- Surface elements that do not form an outer surface of the body are referred to as stabilization surface elements.
- Preferred embodiments provide that the three-dimensional body completely encloses a volume, i.e. each surface of the three-dimensional body is at least partially formed by a surface element of the substrate element.
- the substrate has a security print that is designed such that a pattern continues in the three-dimensional body over a body edge that does not arise exclusively from one of the folds is. This means that the surface elements in the substrate that abut one another at the body edge are not only separated by a fold. A precise formation of the pressure is therefore necessary.
- the three-dimensional body thus gives the impression as if it had been provided with the pattern from the outside in the three-dimensional state, for example printed.
- one of the surface elements has a transparent window area. This creates the possibility of seeing into the interior of the three-dimensional body and verifying features on surface sections that are arranged in the interior of the three-dimensional body.
- Transparent is an object or material through which imaging according to geometric optics is possible for at least one wavelength or a wavelength range of visible light. If transmission of light of one wavelength or a wavelength range through an object/material is possible, but the light is scattered diffusely or stochastically as it passes through, the object/material is referred to as translucent.
- a transparent window area in a surface element of the substrate element can be formed, for example, by a punched out recess.
- a transparent window region is preferably formed in a surface element of the substrate element by means of a transparent element, for example a transparent plastic material.
- a region of the substrate element can consist of a transparent plastic material or several interconnected transparent layers of plastic material.
- the transparent material can be colored so that imaging according to geometric optics is only possible for individual wavelengths or wavelength ranges of visible light.
- the window area is therefore formed by a transparent plastic element.
- the plastic element has a light-refractive property, for example in the form of a magnifying glass, and information can be detected on a surface section inside the three-dimensional body inside the three-dimensional body through which the plastic element can be detected, which is on the surface section in the flat state of the flat substrate element cannot be detected. This creates a hidden security feature that can only be verified without tools when the three-dimensional body is produced from the substrate element by folding it.
- information is encoded in the plastic element, which is projected onto at least one internal surface section of one of the surface elements when light is irradiated onto the plastic element from outside the three-dimensional body, so that this information is transmitted through the surface element can be detected from the outside or through the plastic element inside the three-dimensional body. If at least the surface element onto which the information is projected is translucent, the information can usually be observed or recorded from the outside. Verifying may be or include verifying an existence of projected information. It can also be checked whether the projection is observed on the surface element on which it was expected. However, the content of the information can also be checked against specifications that come from outside the banknote or are contained in the banknote.
- a light-deflecting optical security element is formed on a surface section which is arranged in the interior of the three-dimensional body opposite the window area, which deflects the light when light is irradiated through the window area onto the security element in such a way that Light is deflected at least partially at a distance from the security element onto the one surface section or another surface section arranged inside, so that it can be perceived through the window section or from the outside through a surface element, in particular through the surface element on which the one surface section or the other surface section are formed is.
- the substrate element can have a rectangular shape when flat.
- Other embodiments may include simpler folding patterns such as folding mesh as a substrate element.
- the substrate element often has a polygonal, rather than square, outline shape.
- the banknote has a flat edge region in addition to the substrate element and the substrate element is delimited from the edge region by a material weakening, for example a perforation, so that the substrate element is separated from the edge region the edge element can be separated along the weakening of the material (for example the perforation) without any aids.
- the edge element has no value without the substrate element. This means that the substrate element alone without the edge element is the fully marketable banknote.
- the substrate element can comprise body surface elements and stabilization surface elements, with the stabilization surface elements being arranged inside the three-dimensional body in the folded three-dimensional state or partially overlapping body surface elements.
- the substrate element has incisions for forming plug connections or perforations for forming such incisions.
- FIG. 1 shows a banknote with an edge element and a substrate element
- FIG. 2 shows a schematic view of the substrate element of the banknote according to FIG. 1 folded into a three-dimensional body
- Fig. 3 shows another banknote in a flat state without an edge element
- Fig. 4 is a schematic view of the folded into a three-dimensional body
- Fig. 5 another banknote in the flat state
- FIG. 6 is a schematic view of the substrate element of the banknote according to FIG. 5 folded into a three-dimensional body
- Fig. 7 is a schematic view of a banknote with the folds to form a tetrahedron as a Platonic solid;
- Fig. 8 is a schematic view according to Fig. 7 of the banknote in the three-dimensionally folded state
- 9 to 18 further banknotes alternately first in the flat state (odd figures) and then in the corresponding three-dimensional state (even figures).
- a banknote 100 is shown schematically in FIG.
- the banknote 100 has an edge region 110 and a substrate element 120. Both are flat. This means that a material thickness perpendicular to the plane of the drawing is significantly smaller than the extent in the plane of the drawing.
- the edge region 110 and the substrate element 120 are preferably made from the same substrate material. This can be any material from which banknotes are usually made. For example, this can be banknote paper based on cotton fibers. It is also possible for the substrate material to be a composite made up of several layers.
- the banknote 100 is preferably provided with a security print from a top side 101 and a bottom side 102, which correspond to the top and bottom sides 111, 121, 112, 122 of the edge region 110 and substrate element 120.
- the banknote has a plurality of security elements, as are common in banknotes. For reasons of simplicity, these are neither shown nor explicitly described. For the person skilled in the art, however, it is apparent that these can be formed in any combination in the banknote 100 as shown in FIG. 1, as well as the other banknotes 100 described here.
- optically variable colors, security prints, various printing techniques, watermarks, hologram patches, transparent elements, etc. can be implemented in the banknote.
- the substrate element 120 is delimited from the edge region 110 by a material weakening in the form of a perforation 130, which is formed all around the substrate element 120.
- the perforation 130 can be designed in any shape, as long as it makes it possible to separate the substrate element 120 from the edge region 110 without further aids. In the embodiment shown, the perforation is shown by a dotted line.
- the substrate element 120 also has folds 200, which facilitate buckling of the substrate element 120, in particular after the substrate element 120 has been separated from the edge region 110, along the folds 200.
- folds 200 In order to be able to refer to individual folds 200, these are numbered 201-212 in the illustrated embodiment.
- the folds 200 and the outline edges 140 of the substrate element 120 jointly delimit surface elements 300.
- Some of these form body surface elements 310 which form surfaces of a three-dimensional body 500, which is shown schematically in FIG.
- Others of the surface elements 300 form stabilization surface elements 320, which are generally arranged inside the three-dimensional body 500 after folding.
- the folds 200 are generally designed to be selective in the direction of folding.
- a fold 200 which is shown by a dashed line, favors a folding direction or folding in which the surface sections facing away from an observer are folded towards one another. This is also referred to here as outward folding.
- Folds which are indicated by a solid line, promote a folding direction or folding in which the surface sections 430 facing the viewer are folded onto one another. This is also known as inward folding.
- a security print 600 comprising a triangle is formed on the surface sections 430, which is at an upper outline edge 141 of the outer surface section 431 ends and continues from the fold 212 into the outer surface section 434.
- this banknote/this substrate element 120 is a three-dimensional body 500 with the shape of a cube 501.
- This folded three-dimensional state is shown schematically in Figure 2.
- the outer surface section 431 of the body surface element 311 borders directly on the surface section 434 of the body surface element 314, so that the security print 600 appears to continue seamlessly over the front upper edge 511 of the cube 501. This feature can be used to verify whether it is a real banknote 100 or not.
- a transparent window area 700 is formed by means of a transparent window element 701.
- a transparent window element 701. This can be made, for example, from a transparent, clear plastic.
- the transparent window element 701 contains a volume transmission hologram 711, which, for example, diffracts light of a narrow wavelength range of visible light, for example in the green wavelength range, in such a way that information stored in the volume transmission hologram 711 is in Shape of the lettering 721 “HOLO” is projected onto the inner surface section 444 of the body surface element 314 when white light 800 is irradiated through the window element 701.
- the projection is carried out in such a way that when the projection is viewed through the window element 701, the lettering is perceived as a mirror image.
- the material of the substrate layer element 120 in the area of the body surface element 314 is translucent, so that the lettering “HOLO” 721 can be perceived from the outside as green lettering.
- This feature can also be used to verify banknote 100.
- the window element 701 is formed by a lens formed in a plastic film, which enables information (not shown) to be printed on the inner surface section 444 of the body surface element 314 opposite the window element 701, for example as microwriting, through the window element 701 Magnifying lens of the window element 701 to detect. The fact that this microwriting becomes readable and/or the fact that the microwriting is present and/or content encoded therein can be used to make verification decisions.
- FIGS. 1 and 2 A further embodiment of a banknote 100 is shown in Figures 3 and 4, once in the unfolded flat shape ( Figure 3) and once in the three-dimensional folded state.
- the banknote 100 does not include any edge area.
- FIGS. 1 and 2 A further embodiment of a banknote 100 is shown in Figures 3 and 4, once in the unfolded flat shape ( Figure 3) and once in the three-dimensional folded state.
- the banknote 100 does not include any edge area.
- FIGS. 1 and 2 A further embodiment of a banknote 100 is shown in Figures 3 and 4, once in the unfolded flat shape ( Figure 3) and once in the three-dimensional folded state.
- the banknote 100 does not include any edge area.
- FIGS. 1 and 2 A further embodiment of a banknote 100 is shown in Figures 3 and 4, once in the unfolded flat shape ( Figure 3) and once in the three-dimensional folded state.
- the banknote 100 does not include any edge area.
- This embodiment also differs from the embodiment according to Figures 1 and 2 in that this embodiment has further stabilizing surface elements 371-377 and further folds 213-219. Furthermore, cuts 271-277 are made in the folds 212, 208, 201, 211, 204, 205, 210, through which the further stabilizing elements 371-377 are accommodated in the folded state.
- an optical element 780 is formed, which deflects light 800 irradiated inside the cube 501 through the window element 701, which is formed from a transparent clear film, in such a way that the incident light cones 810 is deflected into two reflected light cones 791, 792, which strike the inner surface sections 441 and 446 and can be detected as bright circles from the outside by the corresponding body surface elements 311 and 315 on the outer surface sections 431 and 436.
- FIG. 5 and 6 show a flat state and a folded state of a further banknote 100, the three-dimensional body of which has the shape of a tetrahedron.
- the other characteristics that are related to the Figures 1-4 or explained elsewhere in the description can be implemented in any combination.
- FIG. 7 and 8 show a banknote 100 in the flat state and in the folded state, the folds 200 of the banknote 100, which are shown in Fig. 7, making it possible to fold a so-called Platonic solid, which also has the shape of a tetrahedron having.
- the letters A to U shown in the surface elements 300 serve to identify the surface elements for the folding instructions given below. In order to fold this 100 banknote into a tetrahedron, the following steps are necessary:
- the schematic shape of the finished folded three-dimensional body 500 is shown in FIG.
- a security feature for example, a pattern of a security print 600 that continues over the body edges is formed, which is, for example, on the back of the inner surface sections marked with the letters K and M, i.e. H. is designed away from the drawing plane and continues, so to speak, over the fold edges K-D, the M-G.
- the border of the pattern on the side facing away from the viewer is indicated by a dash-dot line.
- banknotes 100 are shown schematically, once in the flat state and once in the folded three-dimensional state.
- the resulting three-dimensional shapes differ in a series of banknotes corresponding to the values of the individual banknotes.
- the value of the banknote is therefore linked to a geometric shape of the three-dimensionally folded banknote or the substrate element of the banknote. For example, dice have a value of ten and tetrahedrons have a value of five.
- banknotes shown in Figures 3-18 can also have an edge region in the flat design, from which the substrate layer element shown in the figures is delimited by means of a perforation.
- the cuts 271-276 mentioned in connection with FIG. 3 can be preformed as perforations, which are then converted into the cuts when the three-dimensional body is folded.
