Definitions

  • the invention is based on an ink waste kit for marking documents.
  • Ink waste kits of this type are often used in connection with document transport containers, in particular bank note cassettes for ATMs.
  • containers which are used to hold documents such as certificates, securities or banknotes, unattractive for criminals, in addition to armoring the containers and other countermeasures, attempts are made to mark the contents of the containers as soon as unauthorized persons access the container takes place.
  • Documents that have been marked and have come into circulation must be withdrawn from circulation as quickly as possible. This means that the marking of the documents must make them unusable for further use.
  • This also includes the deposit of marked banknotes at a self-service terminal such as an ATM or ATM. The marking of the documents must therefore be recognizable by a user with the naked eye and equally well detectable by an ATM.
  • Raid colors are known which cause both a visible coloring and a machine-readable identification of the documents provided with the marking.
  • the raid color usually shows some resistance to what is known as leaching, a treatment with chemical reagents to remove, fade, or etch the raid color. This is intended to prevent the marking of documents that were originally rendered unusable being removed and these being returned to payment transactions.
  • the problem with a number of overflow colors is that after a washing-out process, they have a visual appearance similar to dirt or contamination, which can also be found on the document. As a result, it is possible for the traffic to mistakenly take the residue of a marking with an overflow color after a washing-out process for contamination of the document, and the marking effect to be lost as a result.
  • banknotes are increasingly being subjected to a so-called fitness test.
  • the banknotes deposited at a self-service terminal are checked for stains, soiling, tears and holes. Dirty and damaged bills will be retained by the ATM.
  • the banknotes to be checked are guided over a black roller, while damage or soiling is detected by incident light measurement using CIS sensors. As a result, the corresponding areas appear black. It is problematic that when checking the fitness of banknotes, as is carried out in particular in ATMs using banknote readers, edge damage, open tears or holes appear as black areas and cannot be distinguished from black coloring caused by smear color.
  • the object of the invention is therefore to provide an ink waste kit with an overrun color that overcomes the disadvantages of the prior art, the color of which can still be clearly distinguished from contamination and dirt, even if it has been subjected to a washing process, which cannot be distinguished with a fitness test of the banknotes and which has a machine-readability that is not easily washed out or easily obfuscated.
  • an ink waste kit according to claim 1.
  • an overflow ink is described with a reflection of electromagnetic radiation in at least one wavelength sub-range of the visible spectrum between 380 nm and 780 nm, the reflection of the electromagnetic radiation in the visible spectral range of course also including the scattering of radiation at the surface of the fallout color.
  • the degree of scattering depends on the surface texture of the fall color.
  • the reflection of the electromagnetic radiation of at least one wavelength or one wavelength range results in the incident color having a coloration different from black.
  • the raid color retains a marking character and differs from dirt and contamination.
  • the attack color according to the invention has no disruptive effect on a conventional fitness check of banknotes in an ATM using incident light cameras.
  • the fall color has an absorption of electromagnetic radiation in the infrared range.
  • conventional attack colors show no or only a negligible amount Absorption. They are transparent in the infrared range.
  • the infrared absorptive property of the trapping ink of the present invention aids in machine readability.
  • absorption in the infrared range is of particular use since most of the banknote, and particularly the edge of the banknote, is transparent in the infrared range, i.e. non-descript. Therefore, an attack color with an absorption in the infrared range is particularly easy to detect.
  • banknote readers primarily use optical imaging sensors such as CMOS, SMOS and CCD sensors, which have sensitivity in the visible spectral range as well as sensitivity in the near infrared range.
  • the incident color of the ink waste kit has an absorption of electromagnetic radiation in at least one further, second wavelength sub-range of the visible spectrum, which differs from the first wavelength sub-range with regard to the reflection of the electromagnetic radiation.
  • a red, orange, blue, green or violet coloration of the incident color occurs, for example, with a correspondingly complementary reflection of the remaining electromagnetic radiation.
  • These colorings are different from a white coloring. Bright riot colors alarm the consumer to a greater extent than white coloring.
  • a chromatic trap color is particularly advantageous if the trap color should only reach unprinted areas of light-colored documents.
  • the depth of penetration is often not sufficient to wet more than the unprinted edge area.
  • the necessary contrast to bright areas of the document is created by coloring the overflow color, thus facilitating the visual recognition of a document marked with an overflow color.
  • the first wavelength sub-range has radiation with wavelengths between 490 nm and 575 nm and the second wavelength sub-range has radiation with wavelengths between 380 nm and 490 nm and/or between 575 nm and 780 nm.
  • a green overflow color has the advantage that it can still be clearly distinguished from soiling, especially after it has been washed out.
  • a green raid color has high potential for alerting a user.
  • the first wavelength sub-range has radiation with wavelengths between 380 nm and 490 nm and the second wavelength sub-range has radiation with wavelengths between 490 nm and 780 nm.
  • the portion of the absorbed electromagnetic radiation in the infrared range is greater than the portion in the visible spectrum.
  • the absorption of the attack color has a higher value in the infrared range, which is particularly important for machine readability, than the absorption in the visible spectral range.
  • This is particularly desirable when the document is treated with a visible color washout reagent which also reduces the infrared absorbing fraction. This becomes clear when one considers that the highest possible degree of washing out is to be achieved by washing out the overflow color, but the treatment with the chemicals is accompanied by damage to the document, which, particularly in the case of banknotes, can lead to a loss of features that are important for the Passing an authenticity check is absolutely necessary.
  • the incident color has an absorption maximum in the infrared range.
  • the size of the wavelength range can be between 2 and 50 nm, preferably between 2 and 20 nm, particularly preferably between 2 and 5 nm. However, areas that are only 1 nm are also conceivable.
  • absorption maxima also of different sizes, can be distributed over the infrared range. This has the added benefit of being a proof of several narrow-band absorption maxima using a single sensor, whose sensitivity range is usually limited, is very difficult.
  • the attack color emits electromagnetic radiation when excited by electromagnetic radiation.
  • electromagnetic radiation This is given, for example, by the fluorescent properties of the attack color.
  • the raid color absorbs electromagnetic radiation with a lower wavelength and emits electromagnetic radiation with a higher wavelength.
  • the attack color can be excited by electromagnetic radiation with a wavelength below 380 nm. Electromagnetic radiation is emitted in the visible spectral range.
  • the fallout color it is also possible for the fallout color to have up-converter properties in addition to fluorescent properties or alternatively. In this case, the excitation takes place through longer-wave electromagnetic radiation and the result is the emission of shorter-wave electromagnetic radiation.
  • This up-converter property includes the absorption of electromagnetic radiation with a wavelength in the visible spectral range and an emission of electromagnetic radiation that also takes place in the visible range.
  • the fallout color preferably has both fluorescence and up-converter properties. In addition, other luminescent properties of the fall color are also conceivable.
  • the incident paint when excited by electromagnetic radiation in the infrared range, absorbs energy of a higher wavelength while at the same time emitting energy with a lower wavelength.
  • the attack color shows up-converter properties in the infrared range. That is, the incident color absorbs in the infrared range and emits electromagnetic radiation with a lower wavelength than the absorbed radiation in the infrared or visible spectral range. Emission occurs regularly at wavelengths between 380 nm and 1100 nm. It is particularly advantageous if the excitation occurs at wavelengths that lie outside the working range of CCD and CMOS sensors, i.e.
  • an ATM can be equipped with an additional light source for emitting electromagnetic radiation with correspondingly high wavelengths. If the excitation takes place in this long-wave infrared range and the emission also takes place in the infrared range, it is very difficult for criminals to assess whether and to what extent a marking has been washed out.
  • the incident color has at least one colorant, through which the reflection of the electromagnetic radiation takes place in the visible spectral range.
  • the colorant can be an inorganic or an organic colorant, a pigment or a dye.
  • the colorant also has absorption in the infrared range.
  • the colorant has absorption in the visible spectral range and/or up-converter properties in addition to reflecting electromagnetic radiation in the visible spectral range and absorbing in the infrared range.
  • the colorant can exhibit UV fluorescence. If the colorant has several of the properties listed at the same time, the concentration of the colorant in the incident color can be selected to be particularly high, which is a prerequisite for a high optical density of the incident color.
  • the overflow paint has at least one inorganic or organic component through which the absorption of electromagnetic radiation in the infrared range takes place.
  • the component is an up-converter, it consists mainly of halides or chalcogenides of sodium, lithium or yttrium, which form a stable lattice and are doped with certain elements, mostly with transition metals, lanthanides or actinides. Oxides can also be used as lattice structures. Mixtures of these up-converters are also conceivable.
  • the subject matter of the invention is an ink waste kit for marking documents in the event of unauthorized access to the documents, with a raid color, with a reservoir for receiving the raid color and with a releasable protective device for releasing the raid color from the reservoir.
  • One or more ink waste kits may be incorporated into a bill transport cassette, case, or other container.
  • a cartridge can serve as a reservoir for storing the raid color.
  • the overflow color serves to mark the documents both in the visible spectral range and in the machine-readable infrared range.
  • the attack color is released.
  • the release of the overflow color can take place here by applying pressure to the reservoir, with the overflow color leaving the reservoir through a pressure valve.
  • gas is forced into the reservoir via a CO 2 pressure tank.
  • the ink waste kit can be equipped with a distribution device for distributing the overflow color on the documents.
  • the distribution device can be a nozzle, a hose or a distributor arm which is arranged on the pressure valve of the reservoir for the targeted distribution of the overflow color.
  • protective devices for releasing raid paint by means of a detonator are also conceivable.
  • the raid color is provided in a reservoir.
  • the attack color is released from this reservoir when the protective device is triggered. If the overflow color is discharged from the reservoir by the protective device under pressure via a valve, the overflow color can be distributed via nozzles, hoses, distributor arms and the like.
  • Another object of the invention is the use of an overflow color to mark documents.
  • the Figures 1 to 5 show absorption spectra of different attack colors.
  • the degree of absorption is plotted against the wavelength. It should be noted here that the specified degree of absorption is a logarithmic value that corresponds to the English absorbance.
