Definitions

  • the invention relates to devices and methods. preventing the falsification of statements affixed either by printing, either manually, on a printed document.
  • the type of falsification targeted by the the invention is specifically data corruption initials, which are replaced by others, which serve the fraudster's designs.
  • This data can either be “fixed” data, which are the same on all documents of a series (face value of a voucher), i.e. data specific to a specific document; in this case, they are commonly referred to as "variable data" and can be, typically, a signature, a number of series, code, etc.
  • the documents covered by this protection are, in particular, authentic documents or authenticated, checks, traveller's checks, certificates, identity documents, tickets lotteries, titles, etc.
  • the substrate on which these documents are printed so will go from normal paper to the plastic card, through special papers, to watermark, etc.
  • fraudsters start from a worthless (or lesser) document relative value) and alter by scrubbing or scraping some initial data that bother them (nominal value a check, lottery number, name of a beneficiary, etc.) to replace them with others.
  • EP 0 184 529 describes the use of an absorbent substrate the ink used by the variable data.
  • Another method is to give relief to the substrate surface in particular by the pruning process soft (intaglio), which forces fraudsters to alter further the surface of the substrate.
  • An object of the invention is that an attempted fraud is easily detectable, even with a little exercised eye.
  • Another object of the invention is the development of a relatively inexpensive process which can be extended easily to many types of documents.
  • the object of the invention is a protective device against falsification of data entered on a document printed in which, at least in an area intended for affixing variable data, the document includes minus a relief motif, this relief being due exclusively to the thickness of the ink layer used to form this pattern.
  • the ink used preferably contains pigments with optical effect; the optical effect is advantageously a iridescence or opalescence.
  • the relief pattern is affixed above the data to be protected. According to another preferred embodiment, the relief pattern is affixed below the data to be protected.
  • operation b can be performed after operation g.
  • the printing process is preferably selected among the following processes: screen printing, flexography, rotogravure.
  • the polymerization accelerator is activated by an energy supply by radiation electromagnetic, selected from the following: infrared, UV, microwave.
  • Fig. 1 shows the effect of scraping in the case of a classic printed document on flat substrate 8.
  • Scraping by any sharp object 2 of a data to be protected ie a "variable data” 4 (here a letter A) also alters an underlying printed motif 6, leaving a "white area” that the fraudster is forced to put on make-up to hide the falsification.
  • Fig. 2 shows the effect of scraping in the case of a embossed substrate 9: the fraudster is brought, during the scraping, to start the surface of the embossed substrate 9.
  • Fig. 3 shows the result of an attempted falsification of a document protected by the the invention.
  • a pattern 10 is superimposed on the data at protect 4. This pattern 10 appears in relief because it is formed an ink deposited in a thick layer 12.
  • the invention uses an ink containing, in addition to the pigments and a certain amount of solvents, polymerizable materials ("varnishes", monomers), which deposit on the appropriate substrate using a process printing allowing the transfer of a layer of ink thick and the use of large pigments.
  • the ink layer is as thin as possible, and therefore practically two-dimensional.
  • a diaper thin also offers the advantage of making itching more difficult.
  • a pattern dark and opaque it is better to use a delicate pattern such as guilloche (typically, lines of the order of 0.1 to 0.2 mm, spaced even), more difficult to reproduce, and produced with transparent or translucent inks, for example loaded pigments producing a particular optical effect when viewed from a certain angle, like a iridescence or opalescence.
  • guilloche typically, lines of the order of 0.1 to 0.2 mm, spaced even
  • transparent or translucent inks for example loaded pigments producing a particular optical effect when viewed from a certain angle, like a iridescence or opalescence.
  • the data to be protected 4 can be even data authenticating the document, such as an image holographic, whose mere presence (even altered) can be sufficient for an unattentive observer to conclude that authenticity of a document.
  • the most typical case is that of data written to hand (signature, etc.).
  • the reliefs formed by the layer thick 12 are locally crushed at the time of handwritten affixing. Erasing, however careful it, of the data to be protected 4 cannot mask the presence of “damaged” reliefs 16, which makes it possible to identify without difficulties a falsified document.
