Definitions

  • the present invention relates to a document, such as a check and the like, with forgery prevention means.
  • delible inks are used, for example, on checks in the region where the digits related to the amount are written, in the region where the amount is written in letters and in the region related to the payee, but these solutions have not always proved themselves able to clearly indicate that forgery has occurred. In fact, not infrequently, after fraudulently tampering with the writing present in these regions, the forger "reconstructs" the region by applying color so as to conceal the tampering.
  • DE-A-2 801 015 is an identity card made of a synthetic sheet with a writing zone, on said writing zone being applied a first layer of ink suitable for writing on it, on said layer being printed a second layer of ink which is fluorescent when it is illuminated with ultraviolet light, said second layer being printed with a third layer of reactive ink.
  • EP-A-0 176 403 is known an anti forgery method for a document consisting of a P.V.C. substrate, on which a signature is to be applied, consisting in applying a first layer of ink on a zone for applying a signature, said ink including a pigment and a product which gives a certain porosity, applying on some zones of said first layer a transparent porous color which allows to obtain a fluorescence when illuminated with ultraviolet light, applying on said second layer a third layer of a second ink which is a pigmented vinyl ink, and applying the signature on said third layer with a indelible ink.
  • the aim of the present invention is indeed to solve the above described problem by providing a document, such as a check and the like, with forgery prevention means which allows to detect a forgery, even automatically, clearly pointing out even attempts at concealing forgery.
  • a particular object of the invention is to provide a document wherein the forgery prevention means can be integrated in other elements which are normally provided in a check, so that said means may not be immediately detectable to the naked eye, making it even more difficult to reconstruct the region tampered with.
  • Another object of the present invention is to provide a document, such as a check or the like, which by virtue of its peculiar characteristics of execution is capable of giving the greatest assurances of reliability and safety in use.
  • Not least object of the present invention is to provide a document, such as a check and the like, which can be obtained by using printing inks which are easily commercially available.
  • the document such as a check and the like, with forgery prevention means, according to the invention, comprises a sheet-like element, generally designated by the reference numeral 1, which in the specific case of checks can be constituted by a paper sheet with or without a watermark, which defines at least a first portion 2 for indicating the amount in digits, a second portion 3 for indicating the amount in letters, and a third portion 4 for indicating the payee of the check.
  • An important peculiarity of the document according to the invention is constituted by the fact that regions printed with an ink which can be erased by chemical and/or mechanical action, designated by 10, are applied in said portions or in some of said portions. Said ink is selected so as to have a preset color response when it is illuminated by a light source of preset wavelength.
  • the same manufacturing criterion can allow to create a code which can be read, for example by means of a fiber-optics head or similar elements; in this solution, first regions 20 and second regions 21 which have mutually different color responses when illuminated with light sources having preset wavelengths are provided; thus, essentially, when the first and second regions, which appear to have the same color in normal light, are illuminated by a source having a preset wavelength or two different wavelengths, said first and second regions appear to have mutually different colors and it is possible to obtain such a difference that the optical reading head can detect only the regions which respond to a certain wavelength, thus allowing to create a code which can be read automatically by the machine.
  • the forger removes the upper layer, without being immediately aware of the fact, so that upon subsequent verification performed with a light source of preset wavelength, in the region where the upper layer has been removed there will be a different color response which makes the forgery in the preset region immediately evident and obvious.

  2. Dokument nach Anspruch 1, dadurch gekennzeichnet, daß es in diesem mindestens einen Abschnitt zum Schreiben von Angaben einen ersten Bereich (20), der mit einer ersten Farbe bedruckt ist, die durch einen chemischen und/oder mechanischen Vorgang entfernt werden kann, und einen zweiten Bereich (21) umfaßt, der mit einer zweiten Farbe bedruckt ist, die mit einem chemischen und/oder mechanischen Vorgang entfernt werden kann, wobei die ersten und zweiten Farben vorbestimmte und zueinander unterschiedliche Farbreaktionen zeigen, wenn die ersten und zweiten Bereiche mit einer Lichtquelle mit einer vorher ausgewählten Wellenlänge bzw. vorher ausgewählten Wellenlängen beleuchtet werden, um visuell aufzuzeigen, daß sich jemand an Teilen dieser Bereiche zu schaffen gemacht hat.
  3. Dokument nach Anspruch 2, dadurch gekennzeichnet, daß die ersten Bereiche (20) und die zweiten Bereiche (21) einen Code darstellen, der mit einem Faseroptik-Lesekopf erfaßt werden kann.
  4. Dokument nach Anspruch 1, dadurch gekennzeichnet, daß es in dem mindestens einen Abschnitt zum Schreiben von Angaben mindestens einen Bereich umfaßt, der mit einer unteren Schicht (30) einer ersten dokumentenechten bzw. unlöschbaren Farbe bedruckt ist, und mindestens eine obere Schicht (31) einer zweiten Farbe, die durch einen chemischen und/oder mechanischen Vorgang entfernt werden kann, auf der unteren Schicht aufgedruckt ist, wobei die zweite Farbe eine vorbestimmte Farbreaktion zeigt, die sich von der Reaktion der ersten Farbe unterscheidet, wenn diese mit einer Lichtquelle einer vorbestimmten Wellenlänge beleuchtet wird, um visuell darauf hinzuweisen, daß sich jemand zumindest an Teilen der oberen Schicht zu schaffen gemacht hat.
  5. Dokument nach Anspruch 4, dadurch gekennzeichnet, daß die untere Schicht eine Färbung aufweist, die im wesentlichen identisch zu der Färbung der oberen Schicht ist.
