Abstract

A layer of adhesive (2) is coated on the document. Information and/or images (4) are printed onto a non-adherent layer on the lower side of a transfer sheet (3). The sheet is lowered onto the document. After adhesion is complete, the transfer sheet is lifted. An Independent claim is included for the document with security protection as described. PREFERRED FEATURES:- The adhesive is solid at ambient temperatures. Following application of the transfer sheet, the document is heated to secure adhesion. The adhesive is alternatively adherent at ambient temperature and covered by a protective sheet which is removed before transferring the security sheet. The security sheet is transparent. The transfer sheet is adhered by its second side to a support sheet which is raised after application to the adhesive of the document. After removal of the transfer sheet a transparent protective sheet is applied on the document which now carries the information and/or images. The protection sheet has a cold adhesive layer. Further variants of the process, based on similar principles, are described.

Description

L'invention concerne un procédé de réalisation d'un document sécurisé et un document sécurisé obtenu par ce procédé. Plus particulièrement, l'invention concerne la réalisation de documents plastifiés dans lesquels toute tentative de retrait de la protection plastique conduit à la détérioration du document.The invention relates to a method for producing a document. secure and a secure document obtained by this process. More in particular, the invention relates to the production of plasticized documents in which any attempt to remove the plastic protection leads to the deterioration of the document.

L'invention est applicable dans le domaine de la fabrication des passeports, cartes d'identité, badges, etc...The invention is applicable in the field of the manufacture of passports, identity cards, badges, etc ...

Dans le domaine des passeports, par exemple, pour personnaliser un passeport il est connu d'utiliser un film transparent comportant une face adhésive, cette face recevant les informations de personnalisation à l'aide des outils de reproduction du commerce tels que imprimantes laser, à jet d'encre ou thermique. Les informations de personnalisation sont couramment l'identité de la personne, son adresse, son état-civil, sa photographie et elles peuvent comprendre également les empreintes digitales ou tout autre renseignement.In the passport area, for example, for customize a passport it is known to use a transparent film comprising an adhesive face, this face receiving the information of personalization using commercial reproduction tools such as laser, inkjet or thermal printers. Information from personalization are commonly the person's identity, address, his marital status, his photograph and they can also include the fingerprints or other information.

Le film transparent porteur de ces informations est placé dans le livret du passeport face à la page prévue, la face adhésive et donc les informations étant en regard de la page du passeport. Le film et la page du passeport sont rendus solidaires par pressage à chaud.The transparent film carrying this information is placed in the passport booklet facing the intended page, the adhesive side and therefore the information being next to the passport page. The film and the page of passport are joined together by hot pressing.

Cette technique conduit à imprimer des informations sur une couche de colle recouvrant une face de la feuille transparente. On se heurte alors à un problème d'état de surface de la couche de colle. De plus, il y a un risque de déformation des informations lors de l'assemblage de la feuille transparente et de la page de passeport au moment de la fusion de la colle et du collage sous pression.This technique results in printing information on a layer of glue covering one side of the transparent sheet. We collide then a problem with the surface condition of the adhesive layer. Also there are a risk of information distortion when assembling the sheet transparent and from the passport page at the time of glue fusion and pressure bonding.

L'invention permet de résoudre ces problèmes.The invention solves these problems.

L'invention concerne donc un procédé de réalisation d'un document sécurisé, caractérisé en ce que :

  • on réalise une couche de colle sur au moins une face du document ;
  • on imprime, sur une première face d'une feuille de transfert d'informations, une ou des informations et/ou images ;
  • on applique la première face de la feuille de transfert d'informations sur la couche de colle de la face du document.
The invention therefore relates to a method for producing a secure document, characterized in that:
  • a layer of adhesive is produced on at least one face of the document;
  • one or more information and / or images are printed on a first face of an information transfer sheet;
  • the first side of the information transfer sheet is applied to the layer of adhesive on the side of the document.

L'invention nécessite donc de munir le document à sécuriser d'une couche de colle. En contrepartie, l'impression des informations de personnalisation peut se faire sur une feuille de transfert exempt de toute couche de colle.The invention therefore requires providing the document to be secured a layer of glue. In return, the printing of information from personalization can be done on a transfer sheet free of any layer of glue.

L'invention concerne également un document comportant un support recouvert sur une face d'une couche de colle, laquelle porte des informations et l'ensemble étant recouvert par un film de sécurité transparent.The invention also relates to a document comprising a support covered on one side with a layer of adhesive, which carries information and the whole being covered by a security film transparent.

Les différents objets et caractéristiques de l'invention apparaítront plus clairement dans la description qui va suivre et dans les figures annexées qui représentent :

  • les figures 1a à 1d, un exemple de procédé de réalisation selon l'invention ;
  • les figures 2a à 4, des perfectionnements du procédé des figures 1a à 1d ;
  • les figures 5a à 5g, une variante du procédé de l'invention.
The various objects and characteristics of the invention will appear more clearly in the description which follows and in the appended figures which represent:
  • Figures 1a to 1d, an example of an embodiment method according to the invention;
  • Figures 2a to 4, improvements to the method of Figures 1a to 1d;
  • Figures 5a to 5g, a variant of the method of the invention.

En se reportant aux figures 1a à 1d, on va donc décrire tout d'abord un exemple de réalisation simplifié du procédé de l'invention.Referring to Figures 1a to 1d, we will therefore describe everything first a simplified embodiment of the method of the invention.

Comme cela est représenté en figure 1a, on imprime sur la face 30 d'une feuille de transfert d'informations 3 tel qu'un film transparent, les informations 4 de personnalisation qui doivent figurer sur le document à obtenir. Dans ce qui suit, on considérera, à titre d'exemple que le document est un passeport. Dans ce cas, comme indiqué précédemment, les informations de personnalisation sont l'identité, l'état-civil, l'adresse, la photo, etc... du futur possesseur du passeport.As shown in Figure 1a, we print on the face 30 of an information transfer sheet 3 such as a transparent film, the personalization information 4 which must appear on the document to get. In what follows, it will be considered, by way of example, that the document is a passport. In this case, as indicated above, the personalization information are identity, marital status, address, photo, etc ... of the future passport holder.

Par ailleurs, la face 10 de la page du passeport référencée 1 sur les figures est enduite d'une couche de colle 2 (figure 1b). Cette opération d'enduction de colle peut être faite dans le cadre du procédé de l'invention ou être faite préalablement au procédé.In addition, side 10 of the passport page referenced 1 on the figures is coated with a layer of glue 2 (figure 1b). This operation glue coating can be done as part of the process of the invention or be done before the process.

La colle peut être une colle à froid ou une colle à température ambiante et dans ce cas, de préférence, elle est protégée par une feuille de protection non représentée sur la figure 1a. The glue can be a cold glue or a temperature glue room and in this case, preferably, it is protected by a sheet of protection not shown in Figure 1a.

Ensuite, le film 3 porteur des informations 4, tel que représenté en figure 1a, est appliqué sur la face 10 du passeport (figure 1c) avec les informations contre la face 10.Then, the film 3 carrying information 4, as shown in Figure 1a, is applied to the side 10 of the passport (Figure 1c) with the information against side 10.

Si la colle 2 est une colle à froid, le film est appliqué sous une pression P (figure 1d) de préférence uniforme sur toute sa surface contre la face 10 du passeport et cela à chaud (à une température située entre 60 et 130°C, par exemple aux alentours de 100°C) de façon qu'après refroidissement le film soit collé sur la face 10. Cette opération peut être faite en faisant passer le passeport à chaud dans un lamineur.If glue 2 is cold glue, the film is applied under a pressure P (Figure 1d) preferably uniform over its entire surface against the side 10 of the passport and this hot (at a temperature between 60 and 130 ° C, for example around 100 ° C) so that after cooling the film is stuck on side 10. This operation can be made by passing the passport hot through a laminator.

Il est à noter que la face 10 peut être recouverte d'une couche de colle à froid par un procédé de sérigraphie.It should be noted that the face 10 can be covered with a layer of cold glue by a screen printing process.

Si la colle 2 est une colle à température ambiante, la feuille de protection de cette couche de colle est enlevée (si elle a été prévue). Le film transparent 3 est appliqué sur la couche de colle avec les informations 4 en contact avec la couche de colle et une légère pression est appliquée uniformément sur la surface du film transparent comme cela se fait habituellement pour le collage des objets autocollants.If glue 2 is room temperature glue, the sheet of protection of this layer of glue is removed (if it has been provided). The film transparent 3 is applied to the glue layer with information 4 in contact with the adhesive layer and a slight pressure is applied evenly across the surface of the clear film as done usually for sticking self-adhesive objects.

On obtient ainsi un document tel que représenté en figure 1d dans lequel le document 1 porte sur sa face 10 des informations 4 protégées par le film transparent 3. Le film transparent étant rendu solidaire de la colle 2 et les informations étant emprisonnées entre la colle et le film 3, il apparaít évident que toute tentative de retrait du film 3, en vue d'une falsification par exemple, détériorera, voire détruira les informations et rendra inutilisable le document. Ainsi, la feuille de transfert d'information 3 sert donc de film de sécurité pour le document.This gives a document as shown in Figure 1d in which document 1 carries on its face 10 protected information 4 by the transparent film 3. The transparent film being made integral with the adhesive 2 and the information being trapped between the glue and the film 3, it appears obvious that any attempt to remove film 3, with a view to falsification by example, will deteriorate or even destroy the information and will make the document. Thus, the information transfer sheet 3 therefore serves as a film of document security.

Le film 3 peut être en PVC par exemple.The film 3 can be made of PVC for example.

La colle à chaud peut être de type copolymère acétate vinyl/éthylène, copolymère acide acrylique/éthylène, polyéthylène, etc... Il est à noter que des informations de sécurité peuvent être imprimées sur la couche de colle avant collage du film 3.The hot glue can be of the acetate copolymer type. vinyl / ethylene, acrylic acid / ethylene copolymer, polyethylene, etc. note that security information may be printed on the layer of glue before gluing the film 3.

Les figures 2a et 2b représentent le même procédé que celui des figures 1a à 1d mais il a été prévu en plus de recouvrir la face 30 du film 3, d'une couche de gélatine 13 avant d'effectuer l'impression des informations de personnalisation 4. Cette gélatine sert de couche réceptrice pour les pigments de l'impression et permet de fixer ces pigments sur la face 30 du film 3. Après impression, le film 3 est appliqué contre la face 10 du document 1 avec les informations 4 en contact avec la face 10 comme cela a été décrit précédemment.Figures 2a and 2b show the same process as that of FIGS. 1a to 1d but provision has been made in addition to covering the face 30 of the film 3, a layer of gelatin 13 before printing the information personalization 4. This gelatin serves as a receiving layer for pigments of the print and allows to fix these pigments on the face 30 of the film 3. After printing, the film 3 is applied against the face 10 of the document 1 with information 4 in contact with side 10 as it has was previously described.

La figure 3 représente le film transparent 3, avec accolé à sa face 31, une feuille support 32 qui sert à la manipulation du film 3. Après collage du film 3 sur le document 1, la feuille support 32 est retirée.FIG. 3 represents the transparent film 3, with attached to its face 31, a support sheet 32 which is used for handling the film 3. After bonding of the film 3 on the document 1, the support sheet 32 is removed.

La feuille support 32 peut être en plastique, en polyester, en PVC ou en polycarbonate.The support sheet 32 can be made of plastic, polyester, PVC or polycarbonate.

La figure 4 est plus particulièrement applicable aux passeports. Dans le cas où la face 10 de la page 1 du passeport est préencollée par une couche de colle à chaud, pour éviter que lors du stockage des passeports, la face 10 se colle à la page voisine 1' du passeport lorsque celui-ci est fermé, on prévoit de revêtir cette page voisine 1' d'une couche anti-adhésive telle qu'une couche de silicone 14.Figure 4 is more particularly applicable to passports. If side 10 of page 1 of the passport is pre-glued with a layer of hot glue, to prevent the passport from being stored side 10 sticks to the neighboring page 1 ′ of the passport when it is closed, provision is made to coat this neighboring page 1 ′ with a non-stick layer such as than a layer of silicone 14.

Les figures 5a à 5g représentent une variante de réalisation du procédé de l'invention.Figures 5a to 5g show an alternative embodiment of the method of the invention.

La feuille transfert d'informations 3 est revêtue d'une couche anti-adhésive 7 telle que du silicone (figure 5a).The information transfer sheet 3 is coated with a non-stick layer 7 such as silicone (FIG. 5a).

Les informations de personnalisation 4 sont imprimées sur cette couche anti-adhésive (figure 5b).Personalization information 4 is printed on this non-stick layer (Figure 5b).

Par ailleurs, la face 10 du document 1 (passeport) est revêtue d'une couche de colle 2 (figure 5c) du même type que dans le procédé décrit précédemment. Eventuellement, cette couche de colle est imprimée d'informations ou de dessins de sécurisation (figure 5d).In addition, side 10 of document 1 (passport) is coated a layer of adhesive 2 (FIG. 5c) of the same type as in the process described previously. Optionally, this layer of glue is printed information or security drawings (Figure 5d).

La feuille de transfert d'informations 3 est appliquée par sa face portant les informations 4 à la face 10 du document 1 (figure 5e).The information transfer sheet 3 is applied by its face carrying the information 4 on the face 10 of the document 1 (FIG. 5e).

Comme dans le cas décrit en relation avec la figure 1d, la face 30 de la feuille 3 est pressée contre la face 10 avec ou sans chaleur selon que la colle 2 est une colle à chaud ou à température ambiante.As in the case described in connection with FIG. 1d, the face 30 of the sheet 3 is pressed against the face 10 with or without heat depending on whether glue 2 is hot glue or at room temperature.

Les informations de personnalisation fusionnent ainsi avec la couche de colle.Personalization information thus merges with layer of glue.

Ensuite la feuille de transfert d'informations 3 est retirée ce qui est possible en raison de la présence de la couche anti-adhésive 7 (figure 5f).Then the information transfer sheet 3 is removed which is possible due to the presence of the non-stick layer 7 (Figure 5f).

En effet, l'accrochage des pigments des informations est alors plus fort sur le document 1 (en papier). Indeed, the attachment of information pigments is then stronger on document 1 (paper).

Pour sécuriser les informations on peut appliquer ensuite sur le document un film transparent (figure 5g). Comme cela est connu dans la technique, le passeport peut être muni d'un film transparent de sécurité 8 (cousu, agrafé ou collé dans l'articulation du passeport). Ce film de sécurité est recouvert d'une couche de colle 9 à chaud ou à température ambiante (à froid). Dans le cas d'une colle à chaud, le collage se fait par thermoscellage. Dans le cas d'une colle à température ambiante, il suffit d'enlever la feuille protégeant la colle et d'appliquer le film de sécurité sur la face 10 portant les informations. Les informations imprimées dans la couche de colle 4 sont alors recouvertes par une deuxième couche de colle et par le film de sécurité 8.To secure the information we can then apply on the document a transparent film (Figure 5g). As is known in the technical, the passport can be provided with a transparent security film 8 (sewn, stapled or glued in the joint of the passport). This security film is covered with a layer of glue 9 hot or at room temperature (at cold). In the case of a hot glue, bonding is done by heat sealing. In the case of an adhesive at room temperature, it suffices to remove the sheet protecting the glue and applying the security film on the face 10 carrying the information. The information printed in the adhesive layer 4 is then covered with a second layer of glue and with the film of security 8.

La solution consistant à prévoir une colle à chaud sur le document, à imprimer des informations ou dessins de sécurité, à transférer les informations de personnalisation sur cette même couche de colle puis à les fusionner à chaud, apporte un maximum de sécurité contre toute tentative de falsification car les informations de sécurité et les informations de personnalisation forment un tout dans la couche de colle.The solution consisting in providing a hot glue on the document, to print safety information or drawings, to transfer the personalization information on this same layer of glue and then hot melt, provides maximum security against any attempted forgery as security information and information of personalization form a whole in the glue layer.

Un soulèvement du film de sécurité entraíne le soulèvement de la couche de colle 4 ainsi que des informations qu'elle contient. C'est l'ensemble de ce complexe qui sera désolidarisé du papier, ce qui permet de mettre en évidence une tentative de falsification. Le fait lors du soulèvement du film de perdre le fond de protection (informations de sécurité) en même temps que les informations de personnalisation interdit la réutilisation du film de protection.A lifting of the security film leads to the lifting of the glue layer 4 and the information it contains. It is the whole of this complex which will be separated from the paper, which allows highlight an attempt at falsification. The fact during the uprising of the film losing the protective background (security information) at the same time personalization information prohibits re-use of film protection.

L'invention apporte ainsi une solution complète à la protection des informations de personnalisation et fait échec aux différentes méthodes de falsification connues à ce jour.The invention thus provides a complete solution to the protection of personalization information and defeats the different methods of falsification known to date.

Dans ce qui précède, les informations de personnalisation ont été imprimées en mode miroir (inversion géométrique) sur le film de transfert d'informations.In the above, the personalization information has been printed in mirror mode (geometric inversion) on the transfer film of information.

Dans le procédé des figures 5a à 5g, la feuille de transfert 3 peut être une feuille de papier ou plastique traitée superficiellement avec un composé non adhésif pouvant être du silicone ou tout autre produit ayant les mêmes propriétés. In the process of FIGS. 5a to 5g, the transfer sheet 3 can be a sheet of paper or plastic treated superficially with a non-adhesive compound which may be silicone or any other product having the same properties.

La solution consistant à imprimer la couche de colle à chaud 2 avec une impression d'un fond de sécurité offre une sécurité optimale des données transférées. Il est ainsi possible de mixer avec l'adhésif des pigments iridescents, fluorescents ou tous autres éléments de sécurité de telle sorte que l'adhésif présente des propriétés d'authentification et que sa substitution soit aisément décelée.The solution of printing the layer of hot glue 2 with a security background printing provides optimal security for data transferred. It is thus possible to mix with the adhesive of the iridescent, fluorescent pigments or any other security elements so that the adhesive has authentication properties and its substitution is easily detected.
