Definitions

• the present invention relates to a method of marking documents of value and more particularly to a method of marking documents of value or the like contained in a protective enclosure or security transport comprising at least one projection system during an attack, by example, of a product contained in a tank.
• This process makes it possible to smudge almost all of the faces of valuable documents on a more or less large surface, but it does not however make it possible to control the intensity, the shape and the positioning of the marking. Indeed, the marking according to this process is then not homogeneous from one document to another. An insufficiently stained document will not reveal with certainty the origin of the marking, making its legal identification uncertain. In addition, the origin of the marking of the document not being certain, the latter will always be likely to be legally valid or validated.
• One of the aims of the invention is therefore to alleviate these drawbacks by proposing a method of marking documents of value or the like making it possible to control the shape, intensity and positioning of the marking making it possible to know with certainty the origin of said marking and thus rendering said valuable documents systematically unusable or legally identifiable after an attack, for example.
• the method of marking documents of value or the like, contained in a protective enclosure or security transport comprising at least one projection system, during an attack for example, of a product contained in a reservoir is remarkable in that one deposits or introduces, during the printing or the manufacture of valuable documents, at least one ink initially translucent and sensitive to at least one developer. suitable, on or respectively in at least one predetermined marking area of said valuable documents then, the valuable documents being placed in the protective enclosure, at least one product revealing the initially translucent ink is projected onto the valuable documents to show a marking on or respectively in the said predetermined marking area (s) and thus to render unusable or legally identifiable said valuable documents.
• This process is also particularly suitable for verifying the authenticity of a valuable document by providing a temporary positive reaction to a specific revealing liquid sprayed onto it.
• the predetermined marking zones are positioned along at least one of the edges of the valuable documents and on at least one of their faces.
• the product which reveals the initially translucent ink is sprayed in a liquid or gaseous form.
• FIG. 1 is a diagram of a valuable document prepared in accordance with the invention in front view, comprising predetermined marking areas,
• FIG. 2 is a vertical sectional diagram of a protective enclosure according to the invention comprising a bundle of valuable documents and a system for projecting a product.
• the method of marking documents of value requires the preparation of a document of value 1 such as a bank note, for example, provided, as illustrated in FIG. 1, of two predetermined marking zones 2,3 of generally rectangular shape extending along the respectively upper and lower horizontal edges of said document of value 1 and of two other predetermined marking zones 4,5 of shape generally rectangular extending along its vertical edges respectively left and right.
• a document of value 1 such as a bank note, for example, provided, as illustrated in FIG. 1
• the marking areas 2,3,4 and 5 have any shape.
• each marking area 2, 3, 4 and 5 includes a written statement and / or a geometric shape and / or a symbol formed by an ink translucent, that is to say an ink whose transmission coefficient is close to one; an ink sensitive to a revealing product is also chosen in such a way that after exposure to said revealing product, it becomes almost instantly opaque or colored and thus clearly shows the written mention, the geometric shape and / or the symbol providing to documents of value a legal identification. Provision may be made, by selecting a translucent ink and a revealing product in an appropriate manner, for the appearance of the marking in the predetermined zones 2, 3, 4 and 5 to be delayed in time after the projection of said revealing product on the documents. of value 1.
• each predetermined marking area 2, 3, 4 and 5 is capable of comprising several written indications and / or geometric shapes and / or symbols, each color associated with one or more shapes of the marking then making it possible to know with precision the origin of the marking and thus facilitating the legal identification of the document of value 1.
• the written indications, the geometric shapes and the symbols included in the marking areas 2, 3, 4 and 5 are formed from inks each translucent sensitive to a different revealing product so that said written indications and other forms or symbols appear with different colors, each having its own conventional meaning, as a result of the projection of one or more suitable revealing products.
• a protective enclosure 6 as shown in FIG. 2; this enclosure is for example provided with a projection system 7 of a revealing product contained in a reservoir 8 which is triggered when detection means 9 are forced, for example during an attack.
• detection means 9 all the theft or break-in detection means 9 as well as all the projection systems 7 can be used and that these methods or devices are considered here as known means.
• the protective enclosure 6 is capable of comprising either several projection systems 7 connected to several reservoirs 8, or a single projection system 7 connected to several reservoirs 8 each containing a different revealing product to reveal the corresponding ink initially translucent.
• the documents of value 1 being placed in the protective enclosure 6 with respect to the projection 7, the detection means 9, following a break-in for example, trigger the opening of the reservoir 8 containing the revealing product which is then projected by said projection system 7 on the documents of value 1, according to a process well known by the skilled person.
• the projection of the revealing product on the documents of value 1 then shows in the predetermined marking areas 2,3,4 and 5 the written mention and / or the geometric shape and / or the symbol according to a color determined on the one hand by the composition of the ink and on the other hand by the nature of the revealing product to which it is sensitive.
• the color thus revealed is advantageously indelible in order to avoid any subsequent or temporary fraud attempt depending on the intended application.
• the developer can be of any kind and in particular a liquid or gaseous, thermal, sound, light, that is to say photonic, electromagnetic, or even nuclear developer or providing equivalent effects.
