Definitions

  • This invention relates to a solution for improving the security of a secure document by making forgery even more difficult.
  • An object of the present invention is to solve the above mentioned drawback and to provide a solution, which makes forgery even more difficult. This object is achieved with a secure document according to independent claim 1 and with a method for manufacturing a secure document according to independent claim 6.
  • Figure 1 illustrates a first embodiment of a secure document
  • Figures 2a to 2c illustrate a method for manufacturing a secure document.
  • Figure 1 illustrates a first embodiment of a secure document 1.
  • the document comprises a first surface 2 and a second surface 3 on opposite sides of the document.
  • the first surface 2 is turned upwards.
  • the secure document 1 may be any kind of secure document, in other words such a document that needs to be manufactured in a way that makes forgery difficult. Examples of such documents are pages of passports, stamps, share certificates, tax stamps, visas and so on.
  • the secure document 1 comprises first elements including symbols 4, text 5, graphics 6 and 7, or combinations of these, of which some are intended to provide the viewer of the secure document with information and other are intended to complicate forgery.
  • These first elements are provided on the secure document such that they are immediately visible for a viewer in ordinary lighting conditions. Therefore the viewer does therefore not need to have any specific apparatus to view these elements, and the elements are also clearly visible without having to view the secure document from any specific direction.
  • Such first elements may be provided on the secure document by printing, by attaching with an adhesive or by laser engraving, for instance, depending on the material and the type of document.
  • the secure document 1 comprises a second hidden element 8.
  • a second hidden element is provided in three different locations of the secure document.
  • a first location for a second hidden element 8 is partially on top of the symbol 4, which is illustrated as an enlargement in the ellipse 9.
  • a second location for a second hidden element 8 is partially on top of graphics 6, such as a photograph or a drawing, as illustrated as an enlargement in the ellipse 10.
  • a third location for a second hidden element 8 is partially on top of graphics 7, which in this case consists of a background colour of the secure document, as illustrated as an enlargement in the ellipse 11.
  • the second hidden element 8 is in all locations provided at least partially on top of said first elements 4, 6 and 7 as surface irregularities including protrusions and recesses when compared to other parts of the respective first element.
  • Figures 2a to 2c illustrate a method for manufacturing a secure document. This method may be utilized for manufacturing the secure document 1 illustrated in Figure 1 .
  • the manufacturing process begins by taking into use a sheet 12 with a first 2 and a second surface 3, and by providing this sheet 12 with the first elements 4, 5, 6 or 7 as appropriate.
  • the selected first elements are provided in a way that makes them immediately visible to a viewer in ordinary lighting conditions, such as by printing ink on a surface of the sheet 12.
  • the second element 8 will be provided as surface irregularities which are produced by pressing an object with a predetermined shape towards the sheet 12.
  • Figure 2a illustrates a plate 13, such as a steel, zinc or copper plate 13, with a surface into which the symbol, text or graphics of the second element are produced by engraving, etching or machining in some other suitable way.
  • Figure 2b illustrates the plate 13 and the sheet 12 arranged on top of it.
  • a cylinder 14 is used in order to subject a pressure towards the sheet 12 and the plate 13 such that the first surface 2 of the sheet 12 turned towards the plate 13 is subjected to such a pressure, that the shape of the second element 8 is produced on the sheet as surface irregularities including protrusions 15 and recesses 16, as illustrated in Figure 2c .
  • the second surface 3 of the secure document 1 will remain smooth such that the surface irregularities of the second element 8 are not visually detectable from the side of the second surface 3.
  • the second hidden element 8 can be produced with Intaglio printing in a security printer without using printing ink.
  • the method of producing the hidden element 8 is very similar to what has been explained above.
  • the printing process mainly differs from the one explained above in that instead of a plate 13, a second cylinder is utilized. Symbols, text or graphics have been produced into the surface of this second cylinder such that when the document is passed between the two cylinders, the pressure caused by the cylinders will produce the surface irregularities of the second element to the document similarly as was explained above.
