Abstract
A security document, such as a banknote or a cheque, is provided with a perforation pattern (5) having holes (5a, 5b) with elongate cross section. When viewing the perforation pattern (5) from a direction that is non-perpendicular to the surface of the document, different holes will have different optical transmission, which can be verified by eye or electronically. Perforation patterns (5) of this type are hard to forge and easy to verify.
Description
Security document and verification method Technical Field The invention relates to a method for verify-ing the authenticity of a security document as well as to a security document having perforations of elongate cross section.
Background Art Fine perforations have been used successfully as a security feature for security documents, i.e. for documents the authenticity of which can be verified in a reasonably reliable manner, such as bank notes, passports or parts thereof, checks, etc.
Background Art Fine perforations have been used successfully as a security feature for security documents, i.e. for documents the authenticity of which can be verified in a reasonably reliable manner, such as bank notes, passports or parts thereof, checks, etc.
2 describes a security document having a pattern of fine perforations that are visible when viewed in transmission while they are invisible when viewed in reflection. Even though this feature has found to be a very reliable means for authenticating the docu-ment, it is desired to increase the uniqueness of these and similar perforations in order to provide an even higher degree of recognizability and reliability.
WO 00/43216 teaches, inter alia, to add per-forations that extend obliquely through the document and that must be viewed under a given angle. However, manu-facturing such oblique perforations is difficult and their quality is likely to degrade over time, in particu-lar when used for paper or thin plastic sheet documents that are subjected to frequent mechanical stress, such as bank notes.
Disclosure of the Invention Hence, it is an object of the present inven-tion to provide a method and a document of the type men-tioned above that further increases the reliability of this type of a security feature based on perforations.
This object is met by the method and document according to the independent claims.
The invention uses an effect that is observed with perforations having an elongate cross section. When such perforations are viewed from a direction that is non-perpendicular to the surface of the document, the transmission characteristics depend on the orientation of the viewing direction in respect to the directions of smallest and largest diameter of the cross section of the perforations. Hence, viewing the document from an direc-tion as described above allows to determine the authen-ticity of the documents from the observed optical trans-mission of the perforations, e.g. by comparing the ob-served optical transmission to an expected optical trans-mission and rejecting the document as invalid if there is no match.
When viewing a perforation from a direction that is perpendicular to its minimum diameter, large transmission can be observed even if the angle between the viewing direction and the direction perpendicular to the document becomes large. On the other hand, when view-ing a perforation from a direction that is perpendicular to its maximum diameter, the transmission is smaller.
Hence, both these viewing directions are preferred view-ing directions for a verification. Preferably, both view-ing directions are used.
If the document comprises several perfora-tions with different cross sections, a single view along the viewing direction allows to observe differently ori-ented perforations with different expected optical trans-mission values, which further increases the reliability of the verification.
For obtaining very strong visual effects, the minimum diameter of the elongate perforations should sub-stantially be equal to or smaller than the thickness of the document carrier.
In one aspect, the invention provides a security document comprising carrier and a security feature with a plurality of perforations in said carrier, wherein:
a first part of the perforations have an elongate cross section with a minimum and a maximum diameter; and a second part of said perforations have circular cross section; and the perforations of said first part and of said second part have equal area of cross section and therefore uniform transmission when being viewed from a viewing direction perpendicular a surface of said carrier.
In one aspect, the invention provides a security document comprising carrier and a security feature with a plurality of perforations in said carrier, wherein:
a first part of the perforations have an elongate cross section with a minimum and a maximum diameter; and a second part of said perforations have circular cross section;
the perforations of said first part and of said second part have equal area of cross section and therefore uniform transmission when being viewed from a viewing direction perpendicular a surface of said carrier;
said perforations extend through said document in a direction perpendicular to a surface of the carrier.
Brief Description of the Drawings The invention will be better understood and objects other than those set forth above will become ap-parent when consideration is given to the following de-tailed description thereof. Such description makes refer-ence to the annexed drawings, wherein:
Fig. 1 shows a bank note having a security perforation pattern, Fig. 2 shows the security perforation pattern in close view, 3a Fig. 3 shows a detail of the perforation pat-tern of Fig. 2, Fig. 4 is a sectional view of the perfora-tions of Fig. 3, Fig. 5 is a detail of a second possible per-foration pattern, and Fig. 6 is a detail of a third perforation pattern.
Modes for Carrying Out the Invention Fig. 1 shows a bank note having a carrier 1 of paper or plastic with conventional graphical and-tex-tual elements 2, 3, 4 and a security perforation pattern 5.
As shown in Fig. 2, security perforation pat-tern 5 comprises a plurality of perforations (holes) 5h, 5b extending through carrier 1. The perforations are ar-ranged in a two-dimensional array. Preferably, they ex-tend through the whole of carrier 1, but they may also extend only partially therethrough as long as the optical transmission when viewed from a viewing direction perpen-dicular to the surface of carrier 1 is much larger at a perforation than at unperforated locations.
As can be seen from Fig. 2, which is a close-up of perforation pattern 5, two different types of holes are used.
A hole 5a and 5b, respectively, of each per-foration type is shown in Fig. 3. In the shown embodi-1o ment, each hole 5a, 5b has elongate cross section and ex-tends through carrier 1 in a direction perpendicular to the surface la of the same. The cross section is prefera-bly substantially uniform through the carrier.
The cross sections of holes 5a and 5b in the embodiment of Figs. 3 and 4 are of equal elongate shape, but rotated in respect to each other by an angle of 900.
Each hole is of roughly ellipsoidal cross section having a minimum diameter dl and dl' and a maximum diameter d2 and d2', respectively. The minimum diameter dl of hole 5a is substantially parallel to the maximum diameter d2' of hole 5b and vice versa.
The minimum diameter dl and dl', repsec-tively, is preferably smaller or approximately equal to the thickness D of carrier 1 and may be in the range of 50 to 300 m for a bank note, preferably not more than 150 pm. The maximum diameter may be substantially larger, e.g. at least 1.5 times larger than the minimum diameter.
The areas of the cross sections of the holes 5a, 5b are preferably equal. In that case, when the docu-ment is viewed against a light source in optical trans-mission from a viewing direction 7 that is perpendicular to surface la of carrier 1, the transmission of both types of holes is the same and the holes appear equally bright. However, when viewing from a viewing direction 7' that is not perpendicular to surface la, the amount light transmitted through the different types of holes 5a, 5b will generally be different because part of the light will be blocked be the walls of the holes. For example, when viewing the document from direction 7' of Fig. 4, around 50% of the maximum amount of light will be trans-mitted through hole 5a while hole 5b will appear to be 5 substantially blocked.
Generally, a high transmission will be ob-served when viewing the perforation pattern along a view-ing direction that is perpendicular to the direction ml of minimum diameter dl while a low transmission will be observed if the viewing direction is perpendicular to the direction m2 of maximum diameter d2.
This effect can be used for verifying the authenticity of the document by viewing it from at least one viewing direction that is non-perpendicular to sur-face 1a. The observed optical transmission of the perfo-rations can e.g. be compared to an expected optical transmission from this viewing direction.
To simplify visual verification, it is pre-ferred to provide carrier 1 with two types of perfora-tions having differing cross sections, as shown in e.g.
in Figs. 3, 5 or 6. When the document is viewed from a direction non-perpendicular to surface 1a, the perfora-tions of the two groups will generally have differing op-tical transmission, which allows to check the feature by visually comparing the transmissions.
For example, when viewing perforation pattern 5 of Fig. 2 from a viewing direction perpendicular to di-rection ml and non-perpendicular to surface 1a, the per-forations within the cross will generally be better visi-3o ble than those outside it.
In the embodiment of Figs. 3 and 4, the two types of holes 5a, 5b have cross sections that are mutu-ally rotated by 90 . In another embodiment, the holes have cross sections of different shape. Preferably, how-ever, the areas of the cross sections of the different types of points are substantially equal such that the perforations have substantially uniform optical transmis-Sion when viewed along a viewing direction perpendicular to surface la. an example of two holes of such a perfora-tion is shown in Fig. 5.
It is also possible to use a perforation pat-tern having more than two types of points with different cross sections for obtaining even more elaborate effects when viewing the document under an angle.
If the perforation pattern is to be inspected by a human, it is preferred to arrange the types of holes to form a human-recognizable pattern, such as the cross of Fig. 2.
The perforations of perforation pattern 5 are preferably manufactured by laser pulses. For producing a hole with elongate cross section, the beam from the laser can either be moved while applying the pulse or several separate pulses may be applied side by side in spatially overlapping manner.
The production of the perforation pattern is easiest when the dimension of all points is only varied in a single direction because this allows to use a single beam deflector to be operated during hole generation.
This leads to a pattern where the minimum diameters of all holes are equal and parallel to each other.
A corresponding embodiment with elongate holes and circular holes is shown in Fig. 6. The first type of holes 5a has a minimum diameter dl that is equal to both diameters dl' of the second type of holes 5b.
Preparing a small perforation pattern as de-scribed above by purely mechanical means is, at best, 3o difficult. In order to avoid ridges, drilling techniques would have to be used - it is, however, highly difficult to prepare an elongate hole of the type shown here by means of a mechanical drill. Therefore, using elongate holes makes the perforation pattern more difficult to forge using mechanical production techniques.
Furthermore, mechanically manufactured perfo-rations have rougher edges and therefore increased light scattering as compared to perforations generated by laser light.
In order to make a mechanical reproduction of the perforation pattern difficult, the minimum diameter dl, dl' of the holes should preferably be 150 m or less.
In the embodiment shown here, the perforation pattern 5 was used in a banknote, but it may be used in other similar applications, such as in cheques or in the pages of a passport or other document that should be hard 1o to forge. Carrier 1 is preferably paper or a flexible plastic.
While there are shown and described presently preferred embodiments of the invention, it is to be dis-tinctly understood that the invention is not limited thereto but may be otherwise variously embodied and prac-ticed within the scope of the following claims.

Fig. 1 shows a bank note having a security perforation pattern, Fig. 2 shows the security perforation pattern in close view, 3a Fig. 3 shows a detail of the perforation pat-tern of Fig. 2, Fig. 4 is a sectional view of the perfora-tions of Fig. 3, Fig. 5 is a detail of a second possible per-foration pattern, and Fig. 6 is a detail of a third perforation pattern.
Modes for Carrying Out the Invention Fig. 1 shows a bank note having a carrier 1 of paper or plastic with conventional graphical and-tex-tual elements 2, 3, 4 and a security perforation pattern 5.
As shown in Fig. 2, security perforation pat-tern 5 comprises a plurality of perforations (holes) 5h, 5b extending through carrier 1. The perforations are ar-ranged in a two-dimensional array. Preferably, they ex-tend through the whole of carrier 1, but they may also extend only partially therethrough as long as the optical transmission when viewed from a viewing direction perpen-dicular to the surface of carrier 1 is much larger at a perforation than at unperforated locations.
As can be seen from Fig. 2, which is a close-up of perforation pattern 5, two different types of holes are used.
A hole 5a and 5b, respectively, of each per-foration type is shown in Fig. 3. In the shown embodi-1o ment, each hole 5a, 5b has elongate cross section and ex-tends through carrier 1 in a direction perpendicular to the surface la of the same. The cross section is prefera-bly substantially uniform through the carrier.
The cross sections of holes 5a and 5b in the embodiment of Figs. 3 and 4 are of equal elongate shape, but rotated in respect to each other by an angle of 900.
Each hole is of roughly ellipsoidal cross section having a minimum diameter dl and dl' and a maximum diameter d2 and d2', respectively. The minimum diameter dl of hole 5a is substantially parallel to the maximum diameter d2' of hole 5b and vice versa.
The minimum diameter dl and dl', repsec-tively, is preferably smaller or approximately equal to the thickness D of carrier 1 and may be in the range of 50 to 300 m for a bank note, preferably not more than 150 pm. The maximum diameter may be substantially larger, e.g. at least 1.5 times larger than the minimum diameter.
The areas of the cross sections of the holes 5a, 5b are preferably equal.

For example, when viewing the document from direction 7' of Fig. 4, around 50% of the maximum amount of light will be trans-mitted through hole 5a while hole 5b will appear to be 5 substantially blocked.
Generally, a high transmission will be ob-served when viewing the perforation pattern along a view-ing direction that is perpendicular to the direction ml of minimum diameter dl while a low transmission will be observed if the viewing direction is perpendicular to the direction m2 of maximum diameter d2.
This effect can be used for verifying the authenticity of the document by viewing it from at least one viewing direction that is non-perpendicular to sur-face 1a.

Preferably, how-ever, the areas of the cross sections of the different types of points are substantially equal such that the perforations have substantially uniform optical transmis-Sion when viewed along a viewing direction perpendicular to surface la. an example of two holes of such a perfora-tion is shown in Fig. 5.
