Definitions
- the present invention relates to substrates used in the field of the manufacture of valuable documents and security.
- intaglio printing is well known in the state of the art, especially for the printing of valuable papers such as banknotes, checks and other similar documents.
- a printing plate is etched to form a predetermined pattern and the etchings, which correspond to hollows, are then filled with ink which will be carried on the printing medium, which is deformed by pressure, by means of a cylinder for example.
- the surface of the paper that penetrates the engravings is thus marked with the ink that has been deposited previously in them.
- banknotes made of plastic. They have the advantage of greater durability than paper banknotes, thanks in particular to their impermeability, their resistance to moisture, grease or other agents that can accelerate the aging of banknotes, and a better resistance to soiling. . These substrates are for the most part transparent and therefore require a step of applying an opacifying ink prior to printing.
- Australian patent application AU 488,652 discloses a security carrier for making banknotes comprising a substrate of an opaque thermoplastic material bonded to a fabric or nonwoven, particularly a polyamide mesh, contributing to the three-dimensional stability.
- the substrate is printed and has optically variable security elements.
- International application WO99 / 54148 proposes a substrate consisting of an oriented polypropylene layer covered on both sides with a layer of high density polyethylene (HDPE) which has areas of weakness.
- HDPE high density polyethylene
- International application WO99 / 67093 discloses a security document composed of a plurality of polymer layers laminated between them and at least one metal layer. At least one of the polymer layers is bi-oriented and at least one other is an opaque film having cavities having areas of reduced thickness.
- a first disadvantage is that they are not really suitable for intaglio printing which involves high pressures.
- these substrates are generally not compressible and intaglio print rendering on such substrates will be poor.
- intaglio printing on such substrates lacks tactility, forcing suppliers of such substrates to set up devices to mimic tactility, in particular by overprinting invisible marks in relief.
- the intaglio printing process is widely used in the field of secure documents including banknotes.
