Abstract

Claimed is a security paper for the production of e.g. banknotes or identity cards, and incorporating two or more holes (12, 16). The first hole (12) is formed during the paper manufacturing process and bears characteristic marginal (14) irregularities. The second hole is incorporated after the paper manufacturing process has been completed. The second hole is formed by cutting or punching and has a sharply defined edge (18). The two holes have a spatial relationship to each other. The margins around each hole bear supplementary information relating to each other e.g. an image, mark or code. The second hole is surrounded by foil and cut by laser beam. The security paper product is of pre-determined thickness and further incorporates a zone of reduced thickness incorporating the second aperture and a watermark. Further claimed is a process to manufacture a commensurate security document.

Description

The The invention relates to a security paper for the production of security or value documents, such as banknotes, ID cards and the like.

security papers or value documents are often used to hedge with different Authenticity features, which is a verification of the authenticity of the security paper or document of value and at the same time as protection against unauthorized Serve reproduction.

in the For the purposes of the invention, the term "security paper" denotes the unprinted Paper, usually is in quasi endless form and will be further processed at a later date. A "document of value" becomes a document designated for that its intended use is finished. Value documents in the sense of the present invention banknotes, stocks, bonds, certificates, vouchers, checks, high-quality tickets, but also other forgery-prone papers, such as passports and other Identity documents, as well as product protection elements, such as labels, Seals, packaging and the like. The simplified term "security paper" or "value document" concludes below all such documents and product securing means.

The Document WO 95/10420 describes a value document in the after its production is punched through a continuous opening, which subsequently with one the opening outstanding on all sides Cover film is closed on one side. The cover is at least in a subarea transpa rent, so that when trying to document the value copy, the surface shows through and from the copying machine accordingly is reproduced. In this way counterfeits can be easily detected. However, the aperture created by punching may be from a counterfeiter as well be generated. Although the color copy of a true value document shows the transparent area no longer, this area can however later punched out analogous to the real value document and with a matching Cover foil should be closed again. Such fakes are difficult to recognize.

to Remedy has been proposed in the document WO 03/054297, already during the Paper production to create a through hole. Such, opening created during sheet formation has characteristic irregularities in the edge area, which on the finished Paper later can not be produced. The irregularities are particularly evident by the lack of a sharp cutting edge or by irregular attachment of fibers in the edge region and by projecting into the opening of individual fibers. Such generated openings have a similar high security value, such as a watermark created in papermaking or a security thread embedded in papermaking.

Indeed Such openings produced in papermaking vary often in their quality and are not easy to produce reproducible. Partially exists also the risk of having fiber bundles open the opening Close part.

outgoing It is the object of the invention to provide a security paper to avoid the disadvantages of the prior art. In particular, the security paper should be highly tamper-proof the openings produced in papermaking with high reproducibility in the production and good recognizability of the through the openings connect established authenticity features.

These The object is solved by the features of the independent claims. Further developments of Invention are the subject of the dependent claims.

In A first aspect of the invention contains a generic security paper at least two through openings, a first one of the through holes during papermaking is generated and characteristic irregularities in the edge region and a second of the through holes after papermaking by cutting or punching with a sharply defined edge area is generated.

The Outlines of the first and the second through hole stand preferably in a sense context. In particular, can be provided that the outline of the first and the second through opening related or complementary information, such as represent a picture, character or encoding.

In a preferred embodiment, the second, sharply defined opening is produced by laser cutting. The sharply delimited edge surfaces of the second opening can run parallel and perpendicular to the paper surface. In other embodiments, however, the second opening is formed with edge surfaces inclined towards the surface normal. This can be done, for example, in laser cutting by a suitable choice of beam divergence and beam tilt relative to the paper be reached. In particular, beam divergence and jet inclination to the paper surface can be adjusted so that the second opening is produced with edge surfaces which are differently inclined to the surface normal. Flattened edges result in a smoother transition between a covering foil arranged over the openings and the paper substrate, and thus, inter alia, a lower susceptibility to soiling.

Different inclined edge surfaces offer about it In addition, advantages in a mutual lamination of the opening with Slides and minimize in particular those with mutual lamination potential Problem with air entrapment. Furthermore, the openings with inclined edge surfaces opposite vertical edge surfaces An additional optical effect, since they differ depending on the viewing direction appear big.

In an advantageous embodiment of the invention, the security paper a predetermined paper thickness and a thin spot of reduced paper thickness on, wherein at least the second through opening in the region of the thin point is introduced. The thin spot may in particular include a watermark.

The two openings are functional on at least one side of the security paper closed with a film element. In some designs, the openings are even on both sides verschlos sen with a slide. This may include possible problems of air entrapment through the above mentioned inclined edges are minimized.

To Another aspect of the invention includes a generic security paper at least one through opening, where the edge surface the through opening first, sharply delimited partial areas and second partial areas with characteristic irregularities having. First and second sections alternate with each other along the Outline of the opening preferably from. In particular, it may be provided that the first and second portions follow each other along the outline of the opening in irregular sequence alternate.

In In one embodiment, first and second subregions extend each through the entire paper thickness. It can also be provided that first and second portions in a direction along the Thickness of the security paper follow each other and towards each other complete the through opening. For example can in a border section sharply delimited subareas by 90 % of the paper thickness extend while the edge surface for the remaining 10% of the paper thickness is irregular. Such edge sections can also be combined with other margins, in which themselves first or second partial areas completely through the entire paper thickness extend.

A Such sequence of first and second portions along the Thickness of the security paper can be generated, for example be that while the paper making a through opening with characteristic irregularities is generated in the edge region, and the edge region of the opening thus created modified paper production by cutting or punching and characterized sharply limited, at least in some areas. The modification is preferably generated by laser cutting, and here too the above mentioned possibilities the inclination of the edge surfaces consist.

The Sequence of first and second subregions along the thickness of the For example, security paper can also be created by that a piece of paper with the desired Shape of the opening with broken, sharply delineated cut lines in the security paper is defined, and then defined piece of paper then from the security paper torn out, in particular blown out or pulled out. The paper piece is preferably defined by laser cutting, again the above mentioned possibilities of Inclination of the edge surfaces consist.

A another possibility the sequence of first and second parts to create exists in that in the security paper a sharply defined thin spot generated with the shape of the desired opening and that in the area of the thin spot due to the residual paper thickness formed piece of paper torn out of the security paper, in particular blown out or pulled out. Also the sharply limited thin spot is in a preferred process control by laser cutting produced, if desired, with inclined edge surfaces, like explained above.

In an expedient embodiment the security paper has a predetermined paper thickness and a thin place with reduced paper thickness, for example a watermark, on, the through opening introduced in the thin area is.

The through opening is functional on one or even on both sides of the security paper with one Closed foil element.

In a further aspect of the invention, a generic security paper contains at least one through opening produced during papermaking, which has characteristic irregularities in the edge region. The through hole is laser-etched with one Engraving combined, which complements the opening to a projection representation. Preferably, the through opening is closed on one or even on both sides of the security paper with a film element.

To Yet another aspect of the invention includes a generic security paper an embedded foil element, which in parts by papermaking produced window areas is visible. The security paper has further in the region of the film element after the papermaking opening created by cutting or punching with sharply defined Border area on.

In an advantageous embodiment is the sharply defined opening and / or arranged directly next to the film element. Preferably the sharply limited opening with the exception of a possible overlap area formed continuously with the film element.

The Window areas are according to a preferred embodiment on a first main surface of the security paper while the sharply limited opening of the opposite main area of the security paper extends to the film element.

In In all embodiments, the film element can be a security element, in particular a security thread or a security band.

The sharply limited opening is produced with advantage by laser cutting. The edge surfaces of the opening can be inclined be as explained above. In an expedient embodiment the security paper has a predetermined paper thickness and a thin place with reduced paper thickness, for example a watermark, on, the sharply limited opening introduced in the thin area is. The sharply limited opening is functional on one or even on both sides of the security paper with one Closed foil element.

The Invention contains also a value document, such as a banknote, an identity card and The like, with a security paper of the type described. The security paper according to the invention or Value document can for the counterfeiting security be used by goods of any kind.

Further embodiments as well as advantages of the invention are described below with reference to FIGS explains in their representation on a scale and proportion Play has been omitted in order to increase the clarity.

16 in (a) and (b) two embodiments of laser-cut openings with against the surface normal inclined edge surfaces.

The invention will now be described by way of example Banknote explained in more detail. 1 shows a schematic representation of a banknote 10 The two through openings 12 respectively. 16 having. The first of the through openings 12 was doing while making the for the banknote 10 used security paper and has a fibrous, irregular border area 14 on. Such a border 14 is characteristic of the openings already made in sheet formation and can not be subsequently produced by punching or cutting the paper.

The second through opening 16 was only produced after the paper production by laser cutting or with the aid of a punching tool and has a sharply delimited border area 18 on. The two through openings 12 and 16 show, spatially separated, twice the same information, in the embodiment of 1 one isosceles triangle each. It is understood that instead of the triangle also more complex shapes can be used, the outlines of which represent, for example, a number sequence or a simple graphic.

Even if that from the first opening 12 represented information by its irregular border area 14 should not be immediately recognizable, the viewer can through the second contour formed with clear contours 16 establish the relationship between the two forms and recognize the information beyond doubt. By presenting the information twice in different guises, the viewer's attention and attention are directed to the difference between the two openings. The high counterfeit security of the irregularly edged opening 12 becomes so with the clear recognizability of the sharply edged opening 16 combined.

The section of the 2 shows a view of a security paper 20 according to a further embodiment of the invention. The security paper 20 has a first paper-made opening 22 with an irregular border area 24 and a second opening created by laser cutting 26 with a sharp edge 28 on. Again, the outline of the two openings 22 and 26 together in a meaningful context. In contrast to the embodiment of 1 However, they do not present the same information, but form complementary parts of an overall information.

Preferably, the illustrated motif is adapted to the different edge properties of the two openings. For illustration shows 2 a flower motif in which the flower through the first, irregularly bounded opening 22 and the stems and leaves through the second, sharply edged opening 26 are formed. Since flowers look very different and variable in nature, the overall picture looks very realistic. At the same time a high protection against counterfeiting is ensured by the use of the two opening forms.

3 and 4 show further embodiments of designs in which the outline shapes of an irregularly bounded first opening and a sharply edged second opening in a meaningful context.

The embodiment of 3 (a) shows a sun in the form of a circular, irregularly bordered first opening 32 with radially outward-facing rays through laser-cut or punched triangular openings 34 are formed. The from the second openings 34 formed rays in this embodiment, a dependent of the first opening motif. Also in 3 (b) represents the irregularly edged, star-shaped, first opening 36 a main motive, of which the sharply edged, circular, second openings 38 depend graphically.

4 shows a further embodiment of the invention, in which the irregularly bounded openings 42 and the sharply edged openings 44 in each case for the denomination "100" of a banknote 40 complete. As usual, the denomination of the banknote is applied again clearly readable elsewhere, for example, printed. In a real banknote, only one of the designs of the 4 can be used or it can be provided both at different locations of the bill and possibly other designs.

A sense context of the two types of opening can also result from the fact that the irregularly bounded opening is modified by the sharply edged opening, as now with reference to the 5 to 7 explained. 5 (a) shows a view of a security paper 50 , in the first paper production, a first, irregularly bounded opening 52 was introduced. The opening 52 becomes after papermaking by laser cutting with two sharply edged openings 54 modified their positions in 5 (a) dashed lines are shown.

After laser cutting results in a single continuous and continuous opening 56 that, as in 5 (b) shown, due to the two-stage production on the one hand subareas 58 with irregular border and on the other hand subareas 59 with sharp edge. By such a modification, the edge properties of the two types of opening can be combined in a single through opening.

In the embodiment of the 6 In the papermaking process, in a first step, an irregularly bounded opening is formed 62 in the form of a given figure, for example in the form of in 6 (a) shown four-headed figure, in a security paper 60 generated. The irregular border area 64 This figure is then partially recut with a laser. As in 6 (b) illustrated, this results in a continuous opening 66 , on the one hand subareas 68 with irregular border and on the other hand subareas 69 with sharp edge. The relationship and the sequence of the subareas 68 . 69 can be chosen arbitrarily.

7 shows a further embodiment in which, as in the embodiment of 6 , first an irregularly bounded opening 72 in a security paper 70 is introduced, as in 7 (a) shown. After paper making, the opening becomes 72 completely cut with a laser (reference numeral 74 ), where the size of the re-cut 74 a little smaller than the size of the opening 72 is selected. This creates a continuous opening 76 , which are in irregular sequence subareas 78 with irregular border and subregions 79 with sharp edge, as in 7 (b) shown.

A sequence of regular and irregular marginal areas can also be achieved without the involvement of an opening already created in papermaking. For example, the desired shape of a through-going opening 82 Using a laser so from a security paper 80 be cut out that the cut lines 84 do not form a coherent cutting curve, but by non-cut sections 86 are interrupted, as in 8 (a) shown. The cuts 86 form holding webs, which initially prevent the release of the cut-out form.

The cut-out shape can then be blown out, for example, with an air jet or pulled out by means of vacuum. As in the in 8 (b) Detail shown in detail 85 illustrates tears the cut piece of paper in this procedure on the support webs 86 in an irregular way, while the cut lines 84 form sharp edges. The edge area to the opening 82 thus has a sequence of irregular subregions 88 and sharply cut parts 89 on whose relative size and sequence can be chosen almost arbitrarily by the cutting guide during laser cutting.

In the further, in 9 shown embodiment of the invention comprises the security paper 90 a through hole created during papermaking 92 with irregular, fibrous edge. The opening 92 is with engraving lines 94 combined, which are produced by laser etching. The engraving lines 94 are through locally thinned areas in the security paper 90 formed, as described for example in the document WO 98/03348, the disclosure of which is included in the present description in this respect. Location and arrangement of the engraving lines 94 are selected according to the invention so that they the opening 92 to complement a projection view.

When viewed in reflected light are the engraving lines 94 practically indistinguishable, there determines the flat shape of the opening 92 the appearance. On the other hand, if the security paper is viewed in transmitted light, the engraving lines will appear 94 due to the smaller paper thickness clearly out and complete the areal opening 92 to a three-dimensional projection representation. The combination of the irregular opening 92 with the engraving lines 94 leads to a visually striking interplay between 2D and 3D presentation.

According to a further embodiment of the invention, which now with reference to the 10 to 12 is described, the security paper with a film element, such as an embedded security thread or a one-sided covered film strip provided.

10 shows an example of a security paper 100 into which a foil strip 102 is embedded. It puts 10 (a) a supervision of the security paper that 10 (b) and 10 (c) show cross sections through the security paper of 10 (a) along the lines BB and CC. The foil strip 102 was before its embedding in the security paper on the bottom 104 full surface with heat sealing lacquer 107 coated. On the other hand 106 were only traces 108 provided on the edge of the film with heat sealing lacquer, so that the middle film area of the top 106 remains uncoated.

During papermaking, a nonwoven fabric now forms on both sides of the film. In addition, for example, using electric types, on the bottom 104 of the foil strip a window 110 recessed in which the Fo lienelement is visible. On the full surface with heat sealing lacquer 107 coated bottom 104 The fiber fleece is down to the recessed window 110 fixed in the dryer section. On the opposite front 106 On the other hand, only the heat-seal lacquer-covered edge areas are treated 108 fixed in the dryer section.

Subsequently, a laser is placed over the recessed window 110 the opposite side 104 a form 112 cut out as best in the cross section of the 10 (c) to recognize. The laser parameters are chosen so that only the paper, but not the foil strip 110 is cut. This can be achieved, for example, by performing the laser cutting with a laser wavelength for which the film strip 102 transparent and non-absorbent.

The cut-out shape 112 can then be removed with a suction device because of the lack of heat seal coating on the front 106 and the non-stick film surface has failed to bond the cut piece of paper to the film.

Another embodiment with foil element will now be described with reference to 11 and 12 explained. First, poses 11 (a) a supervision of a security paper 120 and the 11 (b) and 11 (c) show cross sections through the security paper of 11 (a) along the lines BB and CC. In the security paper 120 is a security thread 122 embedded, primarily in the papermaking window areas 124 the back of the paper can be seen as in 11 (b) shown.

Next is in the area of the window 124 from the front of the security paper 120 A sharply edged opening with a laser 126 introduced into the paper substrate extending over the security thread 122 extends. For this purpose, the laser parameters are chosen so that although the paper substrate 120 but not the security thread 122 is cut by the laser. In the area of the opening 126 is the security thread 122 then recognizable from both sides, as in 11 (c) shown.

At the in 12 shown alternative design is the laser cut opening 128 in contrast to the design of the 11 not about the security thread 122 led, the security thread is rather from the opening 128 framed. Except for this difference, the views of the 12 (a) to (c) those of 11 (a) to (c).

Unlike 11 is in the embodiment of 12 the surface of the security thread 122 only in the window areas 124 recognizable. Such a configuration is particularly suitable when the laser radiation, the film material of the security thread 122 could damage or undesirably affect. As the security thread usually oscillates, the opening may be 128 typically not perfect on the security thread in this design 122 be centered, as by the in 12 (a) and (c) indicated register variations.

13 shows a design in which a laser with a sharply edged opening 132 in the area of a thin spot 134 of the security paper 130 is generated. The thin spot 134 For example, it can be produced by a suctioned short-former layer (a paper layer produced by jet-spraying the pulp onto a round screen) or by means of electrotypes. As the paper thickness in the area of the thin point 134 is reduced, can be used in laser cutting with lower laser power. As a result, higher cutting speeds are achieved, so that more complex shapes can be realized. This modification can be combined with all embodiments in which a laser is used to inscribe a sharply edged opening in a paper substrate.

Further embodiments of the invention will now be described with reference to FIG 14 and 15 explained. In the embodiment of the 14 becomes a thin spot by using a laser 142 given shape in the paper substrate 140 generated. The paper material is vaporized, burned or otherwise removed. It is just removed so much material that even a small residual thickness 144 of the substrate remains as in 14 (a) shown. Depending on the thickness tolerance of the substrate can be removed in some places so much that no material is no longer available. Since the thin spot is produced by laser cutting, the edge surface is 146 sharp and smooth.

The piece of paper remaining after the laser treatment 144 is then removed by blowing out or sucking out. Since it is only a very thin paper layer, the piece of paper tears 144 out at the edges, creating an irregular section 148 in the edge surface of the now continuous opening 145 as in the cross-sectional view of 14 (b) and the supervision of 14 (c) shown.

Follow the edge of the opening 145 along a direction extending through the paper thickness, starting at the surface 141 of the paper substrate, so follow the sharply defined portion 146 and the characteristically irregular shaped portion 148 each other. When looking at the security paper, the through opening appears 145 from opposite sides of the security paper with different impression, depending on whether the sharp marginal area 146 or the irregular border area 148 bordered on the paper surface.

As an exemplary combination of laser-generated openings with thin spots in the paper substrate ( 13 ) shows the embodiment of 15 first in the security paper 150 paper-making thin film 151 such as a watermark. In the area of this thin spot 151 will then, as related to 14 described, with the laser a second sharply bordered thin spot 152 produces only a small residual thickness 154 of the paper substrate, as in 15 (a) shown.

This remaining piece of paper 154 is torn out by blowing or sucking, leaving at the bottom of the paper substrate 150 an irregular border area 158 is generated as in 15 (b) shown. The edge area created by laser cutting 156 is sharply limited. The resulting through opening 160 is in a watermark area 151 embedded, which clearly appears when viewed in review, see 15 (c) , It is understood that the shape of the opening 160 and the watermark area 151 can also be in a meaningful relationship with each other.

Overall, the edge surface of the opening 160 successively a sharply delimited portion along a direction extending through the paper thickness direction 156 and a characteristically irregular shaped portion 158 on. Again, the through opening appears 160 when viewed from opposite sides of the security paper ago with different impression, depending on whether the sharp bounded edge area 156 or the irregular border area 158 adjacent to the paper surface.

In The described embodiments, the sharply edged opening instead be generated by a laser also by a punching tool. Also it is not necessary that the marginal areas of the laser-cut openings parallel and perpendicular to the paper surface, as in the figures for ease of illustration shown. Rather, it can be beneficial be to skew the laser source and / or the paper when cutting, so that "flattened" edges are generated.

16 shows in (a) and (b) two embodiments in which sharply bounded, laser-cut openings 172 and 174 in paper substrates 170 are introduced. The inclination of the edge surfaces 178 The apertures can be adjusted as desired by choosing an appropriate beam divergence and beam tilt. The openings 172 and 174 are each with a slide 176 covered. As can be seen immediately, the flattened edges result in a smoother transition between the film 176 and the paper substrate 170 , By such edge shapes, the susceptibility to fouling of the openings is significantly reduced.

The design of the 16 (b) in which the edge surfaces have different inclination, moreover, in a (not shown) mutual lamination of the openings with films has proven to be particularly advantageous. Problems with the possible inclusion of air between the opposing films can be minimized by such an edge design.

Also have the openings of the 16 as an additional advantage an additional optical effect, since they appear different sizes depending on the viewing direction.
