DESCRIPTION DESCRIPTION
TITRE : MACHINE ET PROCEDE POUR L’IMPRESSION A HAUTE CADENCE DE TITRES SECURISES TITLE: MACHINE AND METHOD FOR HIGH SPEED PRINTING OF SECURE TICKETS
Domaine technique Technical area
La présente invention concerne les machines d’impression de titres sécurisés, notamment de cartes d’identité. The present invention relates to machines for printing secure titles, in particular identity cards.
La présente invention vise à constituer une machine d’impression sans encre ajoutée qui permette l’impression à haute cadence de titres sécurisés par projection photographique d’une image comprenant des données variables à fixer sur un titre. The present invention aims to constitute a printing machine without added ink which allows high-speed printing of secure titles by photographic projection of an image comprising variable data to be attached to a title.
Techniques antérieures Prior techniques
On connaît des machines d’impression qui permettent d’imprimer des titres sécurisés, par exemple des cartes d’identité, par sérigraphie laser sur un élément en polycarbonate ou par impression à balayage. Printing machines are known which make it possible to print secure titles, for example identity cards, by laser screen printing on a polycarbonate element or by scanning printing.
Ces solutions sont néanmoins relativement longues à mettre en place. De plus, l’impression par balayage ne permet pas l’impression en ton continu, ce qui limite la qualité de rendu des impressions obtenues . Surtout, le balayage par sérigraphie peut parfois souffrir de défauts de sécurisation lorsqu’il n’empêche pas que des données frauduleuses puissent être ajoutées par gravure sur des zones du titre non gravées lors de l’impression. Exposé de l’invention However, these solutions are relatively long to implement. In addition, scanning printing does not allow continuous tone printing, which limits the rendering quality of the resulting prints. Above all, screen printing scanning can sometimes suffer from security flaws when it does not prevent fraudulent data from being added by engraving on areas of the title that are not engraved during printing. Disclosure of Invention
L’invention a pour but de pallier au moins certains des inconvénients précités et de proposer une machine d’impression à haute cadence de titres sécurisés, qui soit capable de cumuler des avantages de rapidité, de fiabilité et de qualité pour sa mise en œuvre. Au vu de ce qui précède, l’invention a pour objet une machine d’impression de titres comportant : The aim of the invention is to overcome at least some of the aforementioned drawbacks and to propose a high-speed printing machine for secure vouchers, which is capable of combining the advantages of speed, reliability and quality for its implementation. In view of the foregoing, the subject of the invention is a ticket printing machine comprising:
- un dispositif de projection d’image, comportant un afficheur et un objectif photographique, - an image projection device, comprising a display and a photographic lens,
- des moyens de transfert d’image d’ au moins un film pelliculaire négatif photosensible vers un film pelliculaire positif. De préférence, les moyens de transfert d’image comportent des rouleaux de pression appliquant ledit film négatif contre le film positif. - Image transfer means of at least one photosensitive negative film film to a positive film film. Of Preferably, the image transfer means comprise pressure rollers applying said negative film against the positive film.
Par exemple, le dispositif de projection d’image comporte des moyens de rétro-éclairage de l’ afficheur. Avantageusement, la machine d’impression comporte deux dispositifs de projection d’image associés respectivement à un film négatif recto et à un film négatif verso et les moyens de transfert d’image appliquent lesdits films négatifs recto et verso de part et d’ autre du film positif. Selon une forme de réalisation, la machine comporte un rouleau pour l’enroulement du film positif et des moyens de déroulement dudit film positif. For example, the image projection device includes means for backlighting the display. Advantageously, the printing machine comprises two image projection devices associated respectively with a front negative film and a back negative film and the image transfer means apply said front and back negative films on either side of the positive movie. According to one embodiment, the machine comprises a roller for winding the positive film and means for unwinding said positive film.
Dans un mode de réalisation, les moyens de déroulement comportent des éléments tendeurs pour le guidage et le maintien tendu desdits films. In one embodiment, the unwinding means comprise tensioning elements for guiding and keeping said films taut.
La machine peut en outre comprendre des moyens de commande des moyens de déroulement dudit film positif en fonction de repères visuels préimprimés sur le film positif. The machine may further comprise means for controlling the means for unwinding said positive film as a function of visual cues preprinted on the positive film.
Avantageusement, l’afficheur comporte un moniteur de résolution supérieure ou sensiblement égale à trois-mille-huit-cent- quarante pixels par deux-mille-cent-soixante pixels. Advantageously, the display comprises a monitor with a resolution greater than or substantially equal to three thousand eight hundred forty pixels by two thousand one hundred sixty pixels.
De préférence, la machine comporte des bobines de rembobinage dudit film négatif. Preferably, the machine comprises reels for rewinding said negative film.
L'invention concerne également un procédé comportant les étapes suivantes : The invention also relates to a method comprising the following steps:
- en chambre noire, dérouler sensiblement simultanément des films positif et négatif jusqu’à la détection d’un repère prévu sur le film positif, - in the darkroom, unroll the positive and negative films substantially simultaneously until the detection of a mark provided on the positive film,
- en chambre noire, afficher des données du titre sécurisé sur l’ afficheur d’un dispositif de projection d’image et projeter via un objectif photographique dudit dispositif de projection d’image l’ affichage dudit afficheur sur le film négatif, - en chambre noire, presser le film négatif contre le film positif jusqu’ à transférer une image de l’ au moins un film négatif sur le film positif, - in the dark room, display data of the secure title on the display of an image projection device and project via a photographic lens of said image projection device the display of said display on the negative film, - in the darkroom, press the negative film against the positive film until an image of at least one negative film is transferred onto the positive film,
- détacher le film pelliculaire négatif du film positif. Brève description des dessins - detach the negative film from the positive film. Brief description of the drawings
L'invention sera mieux comprise à l'étude détaillée d’un mode de réalisation pris à titre d'exemple non limitatif et illustré par les dessins annexés, sur lesquels : The invention will be better understood on detailed study of an embodiment taken by way of non-limiting example and illustrated by the appended drawings, in which:
[Fig 1] représente une machine d’impression selon l’invention. [Fig 2] représente une portion d’un film pelliculaire comportant des données pré-imprimées. [Fig 1] represents a printing machine according to the invention. [Fig 2] shows a portion of a pellicle film with pre-printed data.
[Fig 3] représente les étapes de mise-en-œuvre de la machine d’impression de la Figure 1. [Fig 3] represents the implementation steps of the printing machine of Figure 1.
Description détaillée La Figure 1 illustre une machine d’impression 1 prévue pour réaliser à haute cadence des impressions en ton continu de titres sécurisés 2, notamment des cartes d’identité, à la cadence d’ au moins huit cents cartes par heure. Detailed description Figure 1 illustrates a printing machine 1 provided for producing high-speed continuous-tone printing of secure titles 2, in particular identity cards, at the rate of at least eight hundred cards per hour.
La machine 1 est prévue pour recevoir un film pelliculaire positif 3 pouvant comporter des données préimprimées 4 particulières au type de titre sécurisé 2 à imprimer, telles qu’un fond de carte ou des éléments de certification ou de prévention de la falsification. The machine 1 is designed to receive a positive film film 3 which may include pre-printed data 4 specific to the type of secure document 2 to be printed, such as a base map or elements for certification or prevention of falsification.
La machine 1 peut comporter un rouleau 5 pour l’enroulement du film positif 3et des moyens de déroulement 6 dudit film positif 3, comportant notamment un moteur d’entraînement en rotation 7 du rouleau de film positif 5. The machine 1 may comprise a roller 5 for winding the positive film 3 and means 6 for unwinding said positive film 3, comprising in particular a motor 7 for driving in rotation the roll of positive film 5.
La machine 1 reçoit également au moins un film pelliculaire négatif 8. Contrairement au film pelliculaire positif 3, le film pelliculaire négatif 8 est photosensible. Il peut comporter par exemple un support souple comprenant une épaisseur de sels d’ argent recouverte d’un vernis photosensible qui s’évapore lorsqu’il est exposé à de la lumière. La machine 1 comprend en outre un dispositif de projection d’image 9, comportant un afficheur 10 et un objectif photographique 11. Machine 1 also receives at least one negative film 8. Unlike positive film 3, negative film 8 is photosensitive. It may comprise for example a flexible support comprising a thickness of silver salts covered with a photosensitive varnish which evaporates when it is exposed to light. Machine 1 further comprises an image projection device 9, comprising a display 10 and a photographic lens 11.
Le projecteur 9 permet d’émettre une image 12 de l’ afficheur 10 sur les films négatifs photosensibles 8 via l’objectif 11 de manière à réaliser une impression photographique de cette image 12 sur lesdits films 8. The projector 9 makes it possible to emit an image 12 from the display 10 on the photosensitive negative films 8 via the lens 11 so as to produce a photographic print of this image 12 on said films 8.
On obtient ainsi une impression en ton continu et non à balayage, ce qui prévient certains risques de falsification des titres. L’impression vise notamment à imprimer par photosensibilité des données variables 13 du titulaire du titre 2 sur le négatif 8, avant transfert sur le positif 3 de ces données variables imprimées 13 sur le négatif 8. One thus obtains a printing in continuous tone and not in scanning, which prevents certain risks of falsification of the titles. The printing aims in particular to print by photosensitivity variable data 13 of the title holder 2 on the negative 8, before transfer to the positive 3 of these variable data printed 13 on the negative 8.
Les données variables 13 comprennent par exemple une photographie d’identité et des données d’état civil du titulaire. Variable data 13 includes, for example, an identity photograph and civil status data of the holder.
Avantageusement, l’ afficheur 10 comporte un moniteur à haute résolution, par exemple un écran de type « UHD-4K » (pour « ultra- high définition »), notamment de résolution supérieure ou sensiblement égale à trois-mille-huit-cent-quarante pixels par deux- mille-cent-soixante pixels, de manière à réaliser des impressions particulièrement détaillées. Advantageously, the display 10 comprises a high-resolution monitor, for example a screen of the "UHD-4K" type (for "ultra-high definition"), in particular with a resolution greater than or substantially equal to three-thousand-eight-hundred- forty pixels by two thousand one hundred and sixty pixels, so as to produce particularly detailed prints.
En outre, le dispositif de projection d’image 9 peut comporter des moyens de rétro-éclairage 14 de l’ afficheur 10 et des moyens de réglage du rétro-éclairage, ce qui permet d’ adapter le rétroéclairage au ton du positif qui change selon le type de titre sécurisé à imprimer. In addition, the image projection device 9 may comprise means 14 for backlighting the display 10 and means for adjusting the backlighting, which makes it possible to adapt the backlighting to the tone of the positive which changes according to the type of security document to print.
L’ afficheur 10 est capable de s’allumer et s’éteindre à fréquence élevée et un grand nombre de fois, ce qui permet d’éviter le recours à un obturateur mécanique spécifique, notamment à diaphragme, particulièrement coûteux et fragile à des fréquences d’utilisation importante. The display 10 is able to turn on and off at high frequency and a large number of times, which makes it possible to avoid the use of a specific mechanical shutter, in particular with a diaphragm, which is particularly expensive and fragile at frequencies of significant use.
La machine 1 comporte en outre des moyens de transfert d’image du film négatif vers le film positif 14. Par exemple, les moyens de transfert d’image 14 comportent des rouleaux de pression 15 entre lesquels sont enserrés les films de manière à appliquer le film négatif 8 contre le film positif 3. The machine 1 further comprises means for transferring images from the negative film to the positive film 14. For example, the image transfer means 14 comprise pressure rollers 15 between which the films are sandwiched so as to apply the negative film 8 against the positive film 3.
Ainsi, grâce aux rouleaux de pression 15, le déroulement du film positif 3 permet à la fois que celui-ci reçoive une impression de la part du film négatif 8 sur lequel il est appliqué par les rouleaux de pression 15, et par la même occasion que le film positif 3 entraîne le déroulement du film négatif 8 auquel il est localement joint par appui. Thus, thanks to the pressure rollers 15, the unwinding of the positive film 3 allows both that it receives an impression from the negative film 8 on which it is applied by the pressure rollers 15, and at the same time that the positive film 3 causes the unwinding of the negative film 8 to which it is locally joined by support.
Le film pelliculaire négatif 8 peut être enroulé sur un rouleau de débobinage 16 pour faciliter son déroulement. The negative film stock 8 can be wound on an unwind roll 16 to facilitate its unwinding.
La machine 1 peut en outre comporter des bobines de rembobinage 17 des films négatifs 8 pour faciliter la mise au rebut. The machine 1 may further comprise reels 17 for rewinding the negative films 8 to facilitate disposal.
Avantageusement, la machine d’impression 1 comporte deux fois le dispositif de projection d’image 9, chacun étant associé respectivement à un film négatif recto et à un film négatif verso. Le film positif 3 est alors intercalé entre les films négatifs recto 18 et verso 19 de sorte que les moyens de transfert d’image 14 appliquent lesdits films négatifs 18, 19 de part et d’ autre du film positif 3 pour former un titre 2 imprimé sur ses deux faces. Comme illustré sur la Figure 2, les données préalablement imprimées 4 sur le film positif 3 peuvent comporter des repères visuels 20 espacés régulièrement sur le film positif 3. Advantageously, the printing machine 1 comprises twice the image projection device 9, each being associated respectively with a front negative film and a back negative film. The positive film 3 is then inserted between the recto 18 and verso 19 negative films so that the image transfer means 14 apply said negative films 18, 19 on either side of the positive film 3 to form a printed title 2 on both sides. As illustrated in Figure 2, the data previously printed 4 on the positive film 3 may include visual marks 20 regularly spaced on the positive film 3.
La machine 1 peut en outre comprendre des moyens de commande 21 des moyens de déroulement 6 dudit film positif 3 en fonction des données pré-imprimées 4 sur le film positif 3, en particulier en fonction des repères visuels 20. The machine 1 may further comprise control means 21 of the unwinding means 6 of said positive film 3 according to the pre-printed data 4 on the positive film 3, in particular according to the visual cues 20.
Les moyens de déroulement 6 peuvent en outre comporter des éléments tendeurs 22 permettant de tendre les films tout en les guidant, tels que des galets lisses ou des paliers à roulements. Par exemple, les moyens de commande 21 comprennent des capteurs visuels des repères 20 et un calculateur couplé aux capteurs pour cadencer le déroulement des films 3, 18, 19. The unwinding means 6 may also comprise tensioning elements 22 allowing the films to be tensioned while guiding them, such as smooth rollers or rolling bearings. For example, the control means 21 comprise visual sensors of the markers 20 and a computer coupled to the sensors to clock the unwinding of the films 3, 18, 19.
Les moyens de commande 21 peuvent également être couplées aux dispositifs de projection d’image 9 pour allumer et éteindre l’ afficheur 10 pour chaque impression de titre 2 et pour changer les données variables 13 à imprimer propres à chaque titre 2. The control means 21 can also be coupled to the image projection devices 9 for switching on and off the display 10 for each print of title 2 and to change the variable data 13 to be printed specific to each title 2.
La Figure 3 illustre un exemple de mise-en-œuvre de la machine d’impression de titres sécurisés 1. Cette mise en œuvre peut commencer par une étape E l par laquelle on déroule sensiblement simultanément les films positif 3 et négatifs 18, 19 jusqu’ à la détection d’un des repères 20 prévus sur le film positif 3. Figure 3 illustrates an example of the implementation of the secure document printing machine 1. This implementation can begin with a step E1 by which the positive 3 and negative films 18, 19 are unrolled substantially simultaneously until 'on the detection of one of the marks 20 provided on the positive film 3.
L’étape El se poursuit par une étape E2 par laquelle on affiche des données variables 13 du titre sécurisé 2 sur l’ afficheur 10 du dispositif de projection d’image 9 et, sensiblement simultanément, on projette via l’objectif photographique 1 1 du dispositif de projection d’image 9 l’affichage de l’ afficheur 10 sur le film négatif 8. Step E1 continues with a step E2 by which variable data 13 of the secure document 2 is displayed on the display 10 of the image projection device 9 and, substantially simultaneously, is projected via the photographic lens 11 of the image projection device 9 the display of the display 10 on the negative film 8.
Le processus d’impression se poursuit d’ abord par une étape E3 lors de laquelle on presse le film négatif 8 contre le film positif 3 grâce aux moyens de transfert 14, jusqu’ à transférer une image du film négatif 8 sur le film positif 3 , puis par une étape E4, lors de laquelle on détache le film pelliculaire négatif 8 du film positif 3. On peut en outre en même temps rembobiner le film négatif 8 sur sa bobine de rembobinage 17. The printing process continues first with a step E3 during which the negative film 8 is pressed against the positive film 3 thanks to the transfer means 14, until an image from the negative film 8 is transferred onto the positive film 3 , then by a step E4, during which the negative pellicle film 8 is detached from the positive film 3. It is also possible at the same time to rewind the negative film 8 on its rewind reel 17.
Les étapes E l , E2 et E3 sont réalisées dans des conditions d’obscurité réduite, par exemple en chambre noire. Steps E1, E2 and E3 are carried out under conditions of reduced darkness, for example in a dark room.
De plus, l’étape E4 peut comporter des étapes connues de plastification et de découpe du positif par poinçon de manière à obtenir un titre 2 de format standard, et se poursuivre par une nouvelle étape E l pour une nouvelle impression de titre sécurisé 2. In addition, step E4 can include known steps of lamination and cutting of the positive by punch so as to obtain a title 2 of standard format, and continue with a new step E l for a new printing of secure title 2.
On peut ainsi réaliser un grand nombre d’impressions successives de titres sécurisés 2, et ce à grande fréquence et en haute qualité avec une machine qui limite les coûts pour sa mise-en-œuvre. It is thus possible to carry out a large number of successive printings of secure titles 2, and this at high frequency and in high quality with a machine which limits the costs for its implementation.
