Definitions
- the invention relates to a security paper with at least two types of mottled fibers, which differ in their luminescent properties and which form a coding.
- mottled fibers as a security feature for security documents has been known for a long time. They usually consist of short plastic or cotton fibers that are inserted into security paper during paper production. Mottled fibers have the advantage over other security features, such as planchettes or mica platelets, that mottled fibers are smaller and less visually unobtrusive and therefore have less of an adverse effect on the overall aesthetic impression of the security document.
- DE 677 711 discloses mottling fibers which fluoresce under UV light and are mixed into the paper pulp before the sheet is formed, so that the mottling fibers are then distributed arbitrarily in the volume of the finished security paper. Different fluorescent mottled fibers can also be used, so that mixed fluorescence occurs under UV lighting.
- DE 31 22470-C2 also discloses a security paper with luminescent mottled fibers incorporated therein.
- the mottled fibers consist of cellulose acetate, which are colored in the fiber volume with narrow-band emitting luminescent substances from the group of lanthanide chelates. These luminescent substances can be introduced into the fiber material in a concentration up to 20 times higher than the previously known luminescent substances, and are furthermore distinguished by a relatively narrow-band emission spectrum.
- the mottled fibers can also be used for threads are twisted or woven. If different luminescent individual fibers are used for this, a coding can also be generated which is based on an evaluation of the presence or absence of certain luminescent substances.
- the present invention is therefore based on the object of proposing a security paper with luminescent mottled fibers which represent a code, the code being intended to be very easy to read by machine.
- the invention is based on the knowledge that for a mechanical check of the mottling fibers with a sufficient signal / noise ratio, the mottling fibers with different luminescent properties must be arranged sufficiently spatially separated from one another. For this reason, non-overlapping partial areas are defined on the security paper according to the invention, in each of which a certain type of mottled fiber with certain luminescent properties is arranged. Coding can be represented by a defined geometric arrangement of the partial areas and / or by the presence or absence of the mottled fibers. Due to the arrangement in limited sub-areas, the mottled fibers with the different properties can be easily localized and the luminescent properties can be measured independently of one another without mutual interference.
- the intensity of the measurement signal increases compared to the known security documents due to the higher surface density of mottled fibers in the measurement area to be checked.
- the signal yield can also be increased if special luminescent substances with an intense, narrow-band luminescence emission are used, as are described, for example, in US Pat. No. 5,448,582.
- These luminescent substances are multiphase systems which contain an optically "pumpable" light-emitting material, light-scattering centers and a transparent matrix material. These materials show laser-like effects with a spectrally extremely narrow-band emission. Another advantage of these materials is that the wavelength of the emission band can be set in limited areas during production.
- the light-scattering centers consist of particulate, transparent materials with a preferably high optical refractive index.
- the luminescent substance absorbs part of the flash and is thereby converted into an excited, so-called “optically pumped” state.
- the luminescent light is created by spontaneous emission from the excited state, with at least a part of the emitted luminescent light not leaving the material directly, but rather is scattered several times at the light-scattering centers, which leads to a high amplification of the emitted light intensity and particularly narrow emission bands.
- the use of luminescent substances with narrow-band emission has the advantage that when measuring the luminescent light, the spectral sensitivity range of a detector can be matched to a narrow spectral interval in which the emission band lies. This suppresses background light from neighboring spectral ranges during the measurement and improves the signal / noise ratio.
- luminescent substances that preferably emit narrowband can also be used, since the measurement signal is determined not only by the intensity of the emitted luminescent radiation of a pigment, but also by the concentration of luminescent substance that can be introduced into the mottling fiber and the areal density of the mottling fibers on the paper.
- mottled fibers become more and more apparent and lead to an increasing disturbance of the overall aesthetic impression of the security paper, which is often printed with an artistic representation.
- the areal density of mottled fibers should therefore be in the range of 2 to 20 mottled fibers per square centimeter.
- the disturbance of the overall aesthetic impression can, however, also be reduced by suitably positioning the partial areas on the security paper. This means that the sub-areas are preferably arranged so that the main motif of the artistic representation is not covered.
- the mottling fibers should appear as little as possible when the security document is viewed visually
- the mottling fibers consist of transparent plastic fibers which are colored in volume with luminescent substances which are also largely transparent in the visual spectral range. If the luminescent substances have a certain intrinsic color, they can, if the luminescent light intensity is appropriate, be introduced into the mottled fiber in such low concentrations that the fiber itself still appears largely transparent.
- the fibers can also be provided with the luminescent substance only on the surface, for example in a dye bath.
- Fiber materials that can be processed into thin fibers, such as silk or cotton, can also be used as fiber materials.
- the sub-areas in which the mottled fibers are arranged preferably have the form of strips which extend over the entire width of the security document. They preferably have a width in the range from 5 mm to 30 mm.
- the partial areas can also have any other shape, such as rectangular, round, oval, star-shaped, etc.
- the mottling fibers are introduced during the production of the security paper in such a way that the mottling fibers are at least partially cross-linked with the fiber tissue of the paper and are therefore at least partially covered by paper fibers on the surface of the paper.
- a method is suitable for introducing mottled fibers into endless, strip-shaped partial areas.
- the mottled fibers are slurried in an aqueous suspension and, during paper production, through a tube, the end of which is a special outlet nozzle has, applied to the rotating rotary screen near the point where the sheet formation on the rotary screen is just beginning.
- the layer of the mottled fibers applied in this way is immediately dewatered by a negative pressure generated within the circular screen, as a result of which the mottled fibers, together with the first layer of the paper fibers accumulating on the circular screen, lie firmly on the circular screen.
- the fibers can be applied to the Fourdrinier in a similar manner.
- mottled fibers with different luminescent properties are arranged in parallel in the paper machine.
- the feed devices of the mottled fibers are controlled in accordance with the coding to be applied. If the coding consists solely in the geometrical arrangement of the partial areas provided with different mottled fibers, the feed devices are positioned accordingly on the paper machine at the start of paper production. The mottled fiber is then fed continuously.
- the coding consists exclusively or additionally in the presence or absence of one or more types of mottling fibers, the supply of these mottling fibers must be stopped in accordance with the coding. If the coding does not change during the production of a paper web, it is also sufficient here to place the required feed devices accordingly at the start of production.
- the coding can represent any information, for example the denomination, date of issue, country of issue or the like.
- the finished security paper which can of course have other security elements, such as a security thread or the like, in addition to the coding according to the invention, is then further processed in the usual way, in particular printed and cut into individual security documents, such as banknotes, shares, checks or the like.
- the coding is measured with appropriate sensors for the respective luminescent properties of the mottled fibers to be evaluated and compared with a reference value.
- the luminescent property to be evaluated can be, for example, the luminescence wavelength or the decay time of the luminescence radiation.
- Fig. 1 is a supervision of a security document, here one
- 2a, b are a top view of two security documents, each with four strip-shaped partial areas, which represent a different coding; 3 shows a section of the wavelength spectrum with four defined wavelength intervals for a coding system made of four different luminescent substances;
- Fig. 4 shows an arrangement for measuring the luminescent
- Fig. 5 shows the time course of the electrical signals on
- FIG. 1 shows a top view of a security document 1, here a bank note which is made from security paper 2.
- the border 3 of an image field is shown in dashed lines on the security document 1, in which an artistically designed image representation 4 (not shown in the figure) is often printed on.
- On the security document 1, three stripe-shaped control areas 8a, 8b, 8c are indicated with dash-dotted lines. They denote the areas in which the detector checks the properties of the luminescent mottled fibers. Its position on security document 1 is therefore determined by the coding to be checked.
- all the strip-shaped partial areas 5a, 5b, 5c are provided with mottled fibers of the same type A, i.e. In all sections 5a, 5b, 5c there are mottled fibers with the same luminescent property.
- the coding is represented solely by the distances a, b of the partial areas 5a, 5b, 5c and the control areas 8a, 8b 8c.
- FIG. 2 shows, using the example of two security documents 1 a, 1 b, another possibility for a coding according to the invention.
- the distance a between the individual control areas 8a, 8b, 8c, 8d is constant and the coding is represented by the presence or absence of one or more partial areas with special mottled fibers within the control areas 8a, 8b, 8c, 8d.
- the mottled fibers arranged in the partial areas differ in the luminescent property to be tested.
- the document la only has subareas 7a, 7b within the control areas 8a, 8b, in which there are mottled fibers of type A or B, whereas the document lb only in the control areas 8a, 8d with subareas 7a, having mottled fibers A, D, 7d is provided.
- control areas used and the number of different mottled fibers can be varied as desired.
- the same mottled fibers with the same luminescent substance can be used for all control areas. This has the advantage that the construction of the sensor can be made much simpler.
- the distances between the control areas can additionally be varied analogously to the embodiment shown in FIG. 1.
- any properties of the luminescent substances contained in the mottled fibers can be evaluated, such as eg the luminescence wavelength or the decay time of the luminescence radiation.
- the luminescent substance A emits at shorter wavelengths than the luminescent substances B, C, D.
- all substances A, B, C, D each show a very narrow-band luminescence emission that does not match that of the other luminescent substances used overlaps so that the luminescent substances A, B, C, D can be distinguished very well from one another.
- the luminescence intensity of the substances is also sufficiently high so that the substances can be reliably recognized and detected by machine.
- FIG. 4 schematically shows a possible arrangement for detecting and evaluating a coding, which is shown with the aid of the luminescent substances or mottling fibers having emission lines shown in FIG. 3.
- the checking of the bank note usually takes place in a bank note processing device, through which the bank notes are guided past the sensors at high speeds with the aid of a transport system.
- This transport of the bank note 2 according to the invention is indicated by the arrow 11 in FIG. 4.
- the banknote runs past an illumination source 12, the radiation of which is focused on the document using optics 13.
- the illumination source 12 is selected such that it emits radiation of the excitation wavelength of the individual luminescent substances.
- the excitation wavelengths of the individual Lumines zenzscher in different wavelength ranges, it may be useful to use several excitation sources as the illumination source, each emitting light in the range of one of the excitation wavelengths.
- This detector 16 preferably contains a spectrometer with a diode array, each of the diodes being sensitive to one of the emission wavelengths 23a to 23d.
- the banknote la according to FIG. 2a is transported past under the measuring device shown in FIG. 4 and the mottled fibers A, B, the emission lines 23a, 23b shown in FIG. 3, the detector in the control areas 8a, 8b, 8c , 8d associated measuring channels on the signals shown in Fig. 5.
- the signals I of the measurement channels assigned to the individual types of mottled fibers A, B, C, D are plotted against the time t.
- the time windows 30a, 30b, 30c, 30d shown in broken lines correspond to the control areas 8a, 8b, 8c, 8d and denote the measurement windows in which a signal is expected in each case. If the note la is passed under the sensor in the direction of arrow 11, the control area 8d is first illuminated. Since there are no mottled fibers within this control area, the associated measuring channel does not perceive any signal in the time window 30d. Since the type C mottling fibers are also absent, the associated measuring channel also receives no signal.
- the sensor Only when the partial area 7b or the control area 8b is transported past under the sensor arrangement does the sensor record the emission band 23b of the luminescent substance B in the time window 30b. analog ges applies to the subsequent sub-area 7a or the signal 23a in the time window 30a. If, as already explained, the presence of the luminescence emission 23a, 23b, 23c, 23d in the correct time window 30a, 30b, 30c, 30d means a binary "1" and the absence of a binary "0", the signals in FIG the code 1 1 0 0 is shown.
