Definitions
- the present invention relates to a secured sheet, especially for the production of a secure document.
- “Secure document” means a means of payment, such as a bank note, a check or a restaurant ticket, an identity document, such as an identity card, a visa, a passport or a passport. driver's license, a lottery ticket, a ticket or a ticket to cultural or sporting events.
- the invention relates more particularly, but not exclusively, to secured sheets intended for the production of banknotes.
- the watermark technique is widely used in the field of security papers and paper money in particular, which remains the first-level security of history, identifiable and identifiable by most ticket users, even the man in the street .
- WO2005 / 106118 It has already been proposed by the application WO2005 / 106118 to produce a secured sheet comprising a papermaking substrate provided with a watermark, with openings covered by a security film affixed to one side of the substrate. The openings are made outside the watermark, and visually complement the appearance of the latter.
- the security film may comprise de-metallizations participating in the overall observable pattern.
- US8465625 discloses an aperture made by papermaking, having an irregular edge with fibers protruding into the opening visibly to the naked eye. This opening can contribute to forming a global pattern by cooperating with a watermark arranged around it. The opening may be covered by a film attached to one side of the papermaking substrate. Achieving such an opening with an irregular edge is a complex papermaking operation to be mastered, which makes it relatively more difficult to obtain detailed, reproducible and aesthetic renderings.
- DE 102005022018 discloses a security document having two openings, one with a regular edge and the other with an irregular edge.
- the opening on regular board can be incorporated into a watermark.
- DE 102014016249 discloses a security document comprising a through aperture that can be combined with a security thread or a watermark, the aperture being laser cut.
- the invention aims to further improve the secured sheets, and in particular to provide security easily recognizable by the man and the street with many aesthetic possibilities, while being complex to reproduce for a counterfeiter.
- a security sheet comprising:
- the sheet being characterized in that said at least one opening extends inside the watermark, as delimited by its outer contour.
- inside the watermark is meant the connected surface delimited by a curve following the outermost contour of the watermark.
- a circular ring-shaped watermark will define a disk-shaped connected surface of outer diameter equal to that of the ring.
- the opening may extend inside the watermark and may or may not be superimposed on a watermarked area, i.e., the watermark itself.
- a watermarked area i.e., the watermark itself.
- the opening may be inside the watermark without being superimposed on it if the opening is a smaller diameter hole than that of the inner circle of the ring.
- the area of watering is the one whose thickness is different from the thickness of the vellum. This thickness may be less than that of vellum for a clear watermark, and superior for a dark watermark.
- the outline of the watermark is the pre-existing one before making the cut.
- the cutting can be done or not through a frozen area.
- the cut is made through a watermarked area, it means that part of the watermark is removed by the cutting operation.
- the watermark has a variable thickness of paper and the achievement of a regular edge cut in it requires a cutting tool performance, thus making it more difficult to counterfeit.
- the opening may have various surfaces, which may be less than 1 mm 2 or greater than 1 mm 2 , for example almost to the outer contour of the watermark in which it is made.
- regular edge it is necessary to understand an edge without long free fibers projecting visibly to the naked eye in the opening, unlike the opening obtained by papermaking disclosed in US8465625 cited above.
- the regular edge is preferably an edge obtained by laser cutting, and this edge may be straight, curved, corrugated or indented, the corrugations or teeth being cutting.
- a security sheet comprising:
- At least one representation of a reference pattern in particular in the form of an impression, a metallization / de-metallization or a hologram,
- At least one aperture with a regular edge made by ablation of the papermaking substrate this opening completing the watermark and reproducing with it the appearance and / or the meaning of the reference pattern when the sheet is observed in transmitted light
- at least one security film at least partially transparent or translucent, this film being superimposed at least in part on the opening.
- the secure document is a bank note.
- the security film comprises a plastic support.
- the area of the sheet where the opening is superimposed on the security film is called
- the invention makes it possible to further secure the document with respect to the risks of counterfeiting by proposing a combination making it possible to synchronously observe the watermark and the security film united, either in the light transmitted, either in reflected light.
- the security element may have, in the area of the opening, front and back faces of different aspects. This may include a difference in brightness, contrast, color and / or hue, dimensional patterns, contour and / or different content, and / or different patterns. This difference in appearance is observable in transmitted or reflected light, preferably in reflected light. It is then observable according to at least one angle of observation given on the front and at least one angle of observation given on the back. It can be observable according to at least one illumination, especially in visible light, UV or IR, illuminating the front and at least one illumination, especially in visible light, UV or IR, illuminating the back.
- the front and back faces have different patterns. In this way, the observation can be done in a differentiated way by an asymmetry of appearance on the front and back.
- This combination advantageously makes it possible to overcome the lack of visibility of the window when the associated patterns are too heavily loaded, especially by printing, to be immediately identifiable by the man in the street. It is customary not to overload the print at the watermark, and in particular to deprive the printed area of the print.
- Another advantage that can be provided by the invention is the durable protection of the watermark by the security film, partial or total depending on the overlap the watermark by the film and the presence or not of another protective film, affixed to the opposite side of the papermaking substrate, and called "contre-foil".
- the optical effect present in the window can be united, with "CLEARTEXT" effects visible in transmitted light, and present in reflected light patterns and / or optical effects and / or different colors on each of the faces.
- the security film may advantageously leave at the opening a transparent surface free of visible optical effect.
- the extent of the watermark as delimited by its outer contour may be greater by a factor at least equal to 1.1 to the extent of said at least one opening, better still at least 1.5, more preferably a factor of at least 10 or 20.
- the opening may be small in size, and in particular be a micro-perforation.
- micro-perforation means an opening whose extent is less than or equal to 1 mm 2 .
- Said at least one opening may be disposed in the center of the watermark or elsewhere.
- a central layout can further enhance safety, requiring precise positioning.
- the aperture is positioned relative to a nominal position on the secure document with an accuracy better than +/- 3 mm in the machine direction SM (i.e. in the direction of travel of the substrate in the paper machine) and in the transverse direction ST.
- the measured difference between the expected position of the opening with respect to the watermark and the observed position is measured, and it is checked whether this difference satisfies a predefined statistical law. If so, this may be a further indication of the authenticity of the document.
- the security film preferably comprises at least one security element superimposed at least partially on the opening.
- the security film completely covers the opening.
- the security element may or may not completely cover the opening.
- the security element may be an optically variable device, especially a diffractive device.
- the outline of the security element may be homothetic to that of the opening, or alternatively may be any. A homothetic contour can further enhance safety, being more difficult to achieve. It can also make it easier to detect a bad positioning of the security element with respect to the contour of the opening.
- the security film and the security element can completely cover the aperture, notably being greater than 5 to 20% larger than the extent of the aperture.
- the security element can be optically variable in the area of the opening.
- an optically variable device or OVD for optically variable device in English
- a lenticular, Moire, diffractive security element in particular of the first order (laser hologram, 3D hologram, echelette network or blazed grating in English) or of zero order, or such that a thin film interferential structure, especially monolayer or multilayer structure (Bragg structures, volume holograms, liquid crystals, etc.).

- a diffractive optical element When such an optical element is illuminated, in particular by a beam collimated, it generates an interference pattern producing an image in a viewing plane, which is visible on a surface positioned in this plane, or visible in transmission from this plane.
- Such a diffractive optical element is computer generated, being different from so-called rainbow, Fresnel or volume reflection holograms.
- the security element may have, in the area of the opening, a metal layer and at least one recess therein.
- the outline of the at least one opening may be substantially homothetic to that of the watermark.
- the outline of said at least one aperture may be homothetic of a watermark pattern.
- the watermark may be screened and / or shaded, or other, for example electrotype.
- the film completely covers said at least one opening.
- the film may extend in strip from one edge to the opposite edge of the sheet.

- the method may comprise an optical acquisition of the watermark area, and a real-time control of the laser according to this acquisition, so as to direct the laser by taking as a reference the watermark, to guarantee a predefined positioning of the opening within the watermark. This makes it possible to keep the appearance of the combined pattern formed by the watermark and the opening substantially constant, while taking into account the positioning dispersion of the watermark within the sheet resulting from the paper process.
- the reference pattern may be present on the security film, in particular in the form of an impression, a metallization or a de-metallization, and preferably in the form of a partial de-metallization after metallization (hereinafter "metallization / de-metallization").
- the watermark may comprise several repeating elementary patterns and said at least one opening may have the same contour as one of said elementary patterns.
- the watermark can be of any type, being for example a shaded and / or rasterized watermark.

These security elements may be visible to the naked eye or not, being for example luminescent under a lighting of a Wood lamp emitting in a wavelength of 365 nm. These security elements are said to be second level.
- Other types of additional security elements require for their detection a more sophisticated detection device. These security elements are for example capable of generating a specific signal when they are subjected, simultaneously or not, to one or more external excitation sources. The automatic detection of the signal makes it possible to authenticate, if necessary, the document.
- These security elements comprise, for example, tracers in the form of active materials, particles or fibers capable of generating a specific signal when these tracers are subjected to optronic, electrical, magnetic or electromagnetic excitation. These security elements are said to be third level.

- the watermark 11 becomes clearly visible, as are the text or other negative-writing patterns 35 and 40 made by de-metallizing the film 15.
- the transparent window 32 becomes very bright.
- the watermark 11 is faintly visible, as is the window 32.
- the film 15 is perfectly visible, and may have, for example, a metallic reflection effect, diffractive elements or a color varies depending on the angle of observation or illumination.
- the window 32 becomes perfectly visible, as well as the watermark 11 and the text and other patterns 35 and 40 in negative writing.
- the security film is superimposed on at least one of these micro-perforations and has in the superposition zone a diffractive security element, allowing a beam of light, in particular laser light, to be sent through the opening to generate by projection an image.
- a diffractive security element is described in application WO2014 / 199296.
- the security film is transparent in its area which is superimposed on the micro-perforation.
- the security film may further comprise a diffractive element which is superimposed on a larger aperture of the papermaking substrate.
- the security film may have various security features, which may or may not have the same appearance on the front and back sides of the film.
- the security film has metallizations of different colors on its front and back sides.
- the security film may have microreliefs made for example by embossing the plastic support of the film, and these microreliefs may be metallized if necessary.
- the security film may be in the form of a patch or alternatively a film completely covering one side of the papermaking substrate.
- Two plastic films at least one of which is a security film, can cover the substrate on both sides and sandwich the aperture (s) made through the papermaking substrate. Where appropriate, these two films cover the entire surface of each face of the sheet.
- the aperture can be given any shape, in particular polygonal, non-polygonal, alphanumeric, reproducing the shape of a watermark motif or a pattern appearing elsewhere on the document or security film, for example a pattern printed on the paperboard substrate.
- the outline of the opening can reproduce the shape of a country.
- the invention makes it possible to gather in the same limited area of the document various security features, by the presence of the watermark, the opening and the security film, leaving more room on the document for security printing and other security elements. associates.
- the security film may comprise a lenticular network.
- This network may include micro lenses cooperating with micro-motives to form an image whose appearance varies with the direction of observation.
- the lenticular network may or may not be present in the area of the film superimposed on the opening.
- the lenticular array is present on the film both in an area superimposed on the aperture and elsewhere; alternatively, the lenticular array is present only in the area of the aperture, and the associated effect can be observed through the aperture.
- the zone or regions of the film carrying the lenticular network may complete the watermark pattern.
