Definitions

• a method of printing security documents, as well as a security document is a method of printing security documents, as well as a security document.
• the present invention relates to a method for printing security documents, such as banknotes and securities, including in particular a varnishing step during which there is a protective layer on the surface of said security documents and a step of typographic printing during which at least one typographic element is printed on said security documents.
• security documents such as banknotes and securities
• the invention also relates to such a security document.
• a protective layer is applied to the sheets or the coil on which are printed during one of the final stages of the manufacturing process.
• the present invention provides a method of printing at least one typographic element on security documents such as banknotes and value papers varnished and to overcome these disadvantages.
• the method according to the invention is characterized in that said typographic printing step is carried out after said varnishing step and by forming on said security documents, before said typographic printing step, at least a rough field for receiving said at least one typographic element.
• the roughness of the field created and intended to receive the typographic element allows a good adhesion of the typographic ink.
• Typographic element can also be any other element 1 authentication for security document such as a bar code or other readable pattern and a special machine with elements that differ from a security document to another.
• the rough field consists of a grid of dots or lines.
• the rough field is formed before or after said varnishing step by locally increasing the roughness of the surface of said security documents.
• said rough field is formed by an intaglio printing process the intaglio printing plate whose area intended to form a rough field is or not inked.
• the rough field may be made by stamping before or after the varnishing step or by any other means making it possible to increase the roughness of the surface of the substrate or of the protective layer, for example, a treatment localized chemical or by treatment by means of a beam such as a laser beam striking the surface of the document.
• the size of the rough field is greater than the size of the typographic element to be printed there.
• the protective layer is produced by means of a UV-drying varnish.
• the invention also relates to a security document according to one of claims 11 to 14.
• the invention will be described in more detail with the aid of the single figure schematically showing a banknote seen in plan.
• Banknote 1 is printed recto-verso according to conventional methods used in the field of the printing of banknotes and paper value, that is to say, offset printing, intaglio, Orloff, screen printing etc. .
• a rough field 3 is created, advantageously in an intaglio printing process.
• the intaglio printing plate comprises an area identical in size to the field 3, provided with several notches of different shape and depth which, during the passage of the paper between the intaglio plate and the plate of the printing cylinder, will form on the paper a rough field including in relief a frame of lines and points corresponding to the notches located on the plate intaglio.
• the sheets are sent to the usual finishing facility, control of the printing of the numbering, cutting, formation of bundles etc.
• Field 3 extends around the number or typographic element so as to cover a higher surface (a few tenths of a millimeter is sufficient) and take into account any inaccuracies when printing the numbering.
• a security document such as a bank note, for example, the serial number, a signature, the date of issue, or any other element that it is desirable to print by typography.
• the use of the intaglio printing plate for producing the rough field 3 is a preferred embodiment. Nevertheless, one can alternatively form the rough fields by stamping, by a localized chemical treatment or by means of a beam striking the surface of the security document, for example a laser beam. This operation can also be performed independently before or after the provision of the protective layer. What is important is to create, before the printing of the typographic element, a rough field allowing a good adhesion of the typographic ink on the protective layer.
• the production of the field 3 during intaglio printing is particularly advantageous in that it does not require an additional step. It suffices simply as already mentioned to provide an appropriate field on the intaglio printing plate.
• the invention also relates to a security document, such as that described with reference to FIG. 1, comprising a substrate whose faces bear impressions, a protective layer affixed to said substrate, and a rough field on which a typographic element is printed. affixed to said protective layer.
• the rough field may be formed, before varnishing, roughness formed on the surface of said substrate so that these asperities are reflected on the surface of said protective layer after varnishing.
• the rough field may be formed, after varnishing, asperities formed directly on the surface of said protective layer.
• the asperities are preferably constituted by a grid of dots and / or lines.
