Abstract
Description
L'invention appartient au domaine du marquage sécuritaire de documents.The invention belongs to the field of secure document marking.
L'invention se rapporte à un procédé de marquage sécuritaire d'au moins un signe à transférer sur un document, ledit procédé comprenant :
- une étape de superposition dans laquelle on superpose un film de marquage sur lequel sont formés une pluralité de réseaux de diffraction d'ordre zéro transférable sur ledit document,
- une étape de transfert dans laquelle on transfère sur ledit document, ledit signe à transférer.
- an overlay step in which a marking film is superimposed on which a plurality of transferable zero order diffraction gratings are formed on said document,
- a transfer step in which is transferred to said document, said sign to transfer.
Dans ces procédés de marquage sécuritaire connus, le film présente des signes optiquement actifs comprenant des réseaux de diffraction d'ordre zéro. Ces réseaux de diffraction d'ordre zéro sont connus dans le domaine du marquage sécuritaire et sont par exemple tels qu'ils présentent une couleur bien définie lorsqu'ils sont observés dans une première direction d'observation et une couleur bien distincte lorsqu'ils sont observés à 90°. Ils ont l'avantage d'être difficilement reproductibles par d'éventuels fraudeurs.In these known safe marking methods, the film exhibits optically active signs including zero order diffraction gratings. These zero-order diffraction gratings are known in the field of security marking and are, for example, such that they have a well-defined color when they are observed in a first direction of observation and a distinct color when they are observed at 90 °. They have the advantage of being difficult to reproduce by possible fraudsters.
L'activation optique est obtenue par la présence de réseaux de diffractions au niveau des signes. Ces signes ont par exemple la forme de caractères numériques. Les réseaux de diffraction d'ordre zéro correspondant aux signes à transférer sur un document sont intégrés au film dans des zones relativement transparentes appelées « patchs » en langue anglaise, ou pastille, recouvrant les réseaux de diffraction. Cette pastille dépasse le réseau de diffraction correspondant au signe à appliquer, et s'étend généralement sur toute la largeur du film.Optical activation is achieved by the presence of diffraction gratings at the sign level. These signs have for example the form of numerical characters. The zero-order diffraction gratings corresponding to the signs to be transferred to a document are integrated into the film in relatively transparent areas called "patches" in the English language, or lozenge, covering the diffraction gratings. This pellet exceeds the diffraction grating corresponding to the sign to be applied, and generally extends over the entire width of the film.
Lors du transfert à chaud, c'est l'intégralité de la pastille qui est déposée sur le document. Lors de ce transfert, la zone de la pastille qui recouvre le signe et la zone de la pastille qui ne recouvre pas le signe sont donc transférés ensemble.When hot transfer, it is the entire chip that is deposited on the document. During this transfer, the area of the pellet that covers the sign and the area of the pellet that does not cover the sign are transferred together.
Or, la zone de la pastille qui ne recouvre pas le signe réfléchit la lumière à l'ordre zéro, et parasite la lisibilité du signe, lorsque celui-ci est sous la forme d'un réseau de diffraction à l'ordre zéro. La zone de la pastille provoque donc une réflexion vitreuse qui gêne la lecture à l'ordre zéro pour les réseaux de diffraction d'ordre zéro.However, the area of the pellet which does not cover the sign reflects the light at zero order, and parasitizes the legibility of the sign, when it is in the form of a zero-order diffraction grating. The area of the pellet therefore causes a glassy reflection which hinders the zero-order reading for zero-order diffraction gratings.
Les procédés de marquage sécuritaire d'au moins un signe à transférer sur un document ont donc l'inconvénient que la lisibilité du ou des signes marqués sous la forme d'un réseau de diffraction d'ordre zéro est mauvaise.The methods for securely marking at least one sign to be transferred to a document therefore have the disadvantage that the readability of the sign (s) marked in the form of a zero-order diffraction grating is poor.
L'invention vise à pallier cet inconvénient.The invention aims to overcome this drawback.
Un but de l'invention est donc d'améliorer la lisibilité des signes marqués sous la forme d'un réseau de diffraction à l'ordre zéro lors d'un marquage sur un document.An object of the invention is therefore to improve the readability of the signs marked in the form of a zero-order diffraction grating during marking on a document.
Un autre but de l'invention est de permettre un marquage de signes sous la forme d'un réseau de diffraction à l'ordre zéro sur un support sans que ces éléments ne soient recouverts par une couche de protection.Another object of the invention is to allow marking of signs in the form of a zero-order diffraction grating on a support without these elements being covered by a protective layer.
Au moins un de ces buts est atteint par un procédé selon la revendication 1.At least one of these objects is achieved by a method according to
Grâce à un tel procédé et notamment au fait que le fer a la forme du signe à transférer, il est possible de transférer directement le signes sur un document sans transférer d'éventuelles couches ou pastilles recouvrant les signes sur le film de marquage, ou d'autres éléments perturbants la lisibilité des signes.Thanks to such a method and in particular the fact that the iron has the shape of the sign to be transferred, it is possible to directly transfer the signs to a document without transferring any layers or pellets covering the signs on the marking film, or other disturbing elements the legibility of the signs.
Dès lors, seuls les signes étant transférés, la lisibilité de ces signes à l'ordre zéro est améliorée.Therefore, only the signs being transferred, the readability of these signs to zero order is improved.
On connaît également dans l'état de la technique des films de marquage comprenant des pastilles, les pastilles comprenant au moins deux signes à marquer, chacun des signes ayant des propriétés optiques différentes.Also known in the state of the art marking films comprising pellets, the pellets comprising at least two signs to mark, each of the signs having different optical properties.
Dans le cas où il y a deux signes à marquer sous la forme de réseaux de diffraction à l'ordre zéro ayant des propriétés optiques distinctes, le problème mentionné ci-dessus est encore plus grand puisque les zones comprises entre ces signes à marquer peuvent nuire à la lisibilité des signes si elles sont transférées en même temps que les signes sur le document.In the case where there are two signs to be marked in the form of zero-order diffraction gratings having distinct optical properties, the problem mentioned above is even greater since the areas between these signs to be marked may be detrimental. the legibility of the signs if they are transferred together with the signs on the document.
Ce problème est résolu par un procédé selon la revendication 2. Grâce aux deux fers de marquage ayant la forme des signes à marquer, il est possible d'obtenir des signes ayant des propriétés optiques distinctes de bonne lisibilité.This problem is solved by a method according to
Ces deux signes de marquage sont des réseaux de diffraction d'ordre zéro lisibles à l'ordre zéro par contraste direct avec le substrat (diffusant).These two marking signs are zero-order zero-order diffraction gratings in direct contrast with the substrate (scattering).
Cette solution permet d'éliminer le problème de la réflexion vitreuse à l'ordre zéro qui parasite la lecture.This solution makes it possible to eliminate the problem of the vitreous reflection at the zero order which parasitizes the reading.
L'invention concerne plus généralement un procédé consistant à déposer une marque optique bicolore pour identifier et authentifier rapidement un document de type billet de banque ou autre document portant un élément composite nécessitant une identification visuelle immédiate par une personne sans qualification ni expertise particulière. Cette marque ne doit pas pouvoir être facilement reproduite ni contrefaite. Elle offre également la possibilité d'un contrôle de niveau expert.The invention more generally relates to a method of depositing a two-color optical mark for quickly identifying and authenticating a bank note document or other document carrying a composite element requiring immediate visual identification by a person without particular qualifications or expertise. This mark must not be easily reproduced or infringed. It also offers the possibility of expert level control.
La forme de ces éléments est donnée directement par la forme du fer de marquage à chaud.The shape of these elements is given directly by the shape of the hot stamping iron.

Avantageusement, le film présente deux bandes uniformes d'effets optiques distincts respectivement de part et d'autre d'une ligne longitudinale.Advantageously, the film has two uniform bands of distinct optical effects respectively on either side of a longitudinal line.

Selon une variante, on transfère au moins les deux signes d'une dite paire sur le document à authentifier.According to one variant, at least the two signs of a said pair are transferred to the document to be authenticated.
Selon une variante, la forme des fers de marquage à chaud est variable d'un document à l'autre et permet de personnaliser les signes d'authentification.According to one variant, the shape of the hot stamping irons varies from one document to another and makes it possible to customize the authentication signs.
