Description

1 Circuits optiques imprimés La présente invention concerne principalement les dispositifs à réseau lenticulaire, qui sont composés d'un réseau lenticulaire 1 et d'une image codée 2. Selon l'emplacement du spectateur, ce dernier voit à travers chaque lentille optique une partie différente de l'image codée, et à travers l'ensemble des lentilles, une matrice de zones de l'image codée qui forment une image. Ces procédés connus sont utilisés pour voir des images en relief, ou pour voir des animations. On connait la demande française FR/08-2636 qui décrit et revendique un procédé de fabrication de dispositif à réseau lenticulaire consistant à déposer par tout moyen connu une ou plusieurs couches d'une substance transparente liquide sur des surfaces dites surfaces élémentaires d'un film transparent, et à rendre ensuite cette substance solide par tout moyen connu comme le refroidissement, le séchage ou la polymérisation, pour que les sous-ensembles de ladite substance élémentaire ainsi devenus solides forment des lentilles optiques convergentes dites lentilles élémentaires 11, 12, 13 et suivantes, caractérisé par le fait que lesdites surfaces élémentaires sont suffisamment espacées les unes des autres pour que des phénomènes de tension superficielle ne puissent pas entraîner la fusion de deux lentilles élémentaires voisines en une seule. La revendication N°4 de cette demande décrit et revendique une variante de ce procédé, dans laquelle on imprime des volumes de séparation et suivants desdites lentilles élémentaires 11, 12, 14 et suivantes. Avec des réseaux lenticulaires à haute résolution, les lentilles sont très petites, et certains procédés d'impression ne permettent pas de garantir une précision de placement parfaite entre les différentes couches d'encre. Ce problème se pose aussi pour d'autres dispositifs de la même famille, que l'on peut regrouper sous l'appellation générale de circuits optiques imprimés. La présente invention permet de résoudre ce problème et ouvre la voie à de nombreuses applications des réseaux lenticulaires et autres circuits optiques imprimés à haute résolution qui étaient impossibles jusqu'à maintenant. Le procédé proposé est un procédé de fabrication de circuit optique imprimé, consistant • à créer des protubérances transparentes 11, 12, 13 et suivantes par le dépôt d'une substance liquide sur un média 10 • à rendre ensuite cette substance solide par tout moyen connu comme le refroidissement, le séchage ou la polymérisation, • et à déposer ensuite une couche Cn+l de substance liquide sur des parties différentes dudit média 10. Selon d'autres caractéristiques de l'invention : • on dépose une couche d'encre Cn+l sur la totalité de la surface comportant des lentilles protubérances, et que l'on nettoie la couche Cn+l avant de la rendre solide, de telle sorte qu'elle n'occupe plus que sensiblement la surface 20 située entre lesdites protubérances ; • le nettoyage de la couche Cn+l est fait avec un moyen de nettoyage connu assez rigide pour ne pas toucher les espaces entre les protubérances ; • ladite couche Cn+l est noire ; The present invention relates primarily to lenticular array devices, which are composed of a lenticular array 1 and a coded picture 2. Depending on the location of the viewer, the viewer sees through each optical lens a different part. of the coded image, and through the lens assembly, a matrix of areas of the coded image that form an image. These known methods are used to view relief images, or to view animations. French Application FR / 08-2636, which describes and claims a method for manufacturing a lenticular array device consisting in depositing by any known means one or more layers of a liquid transparent substance on surfaces referred to as elementary surfaces of a film, is known. transparent, and to then render this solid substance by any means known as cooling, drying or polymerization, so that the subsets of said elementary substance thus become solid convergent optical lenses said elementary lenses 11, 12, 13 and characterized in that said elementary surfaces are sufficiently spaced from one another so that surface tension phenomena can not cause the fusion of two neighboring elementary lenses into one. Claim 4 of this application describes and claims a variation of this method, in which separation and subsequent volumes of said elementary lenses 11, 12, 14 and following are printed. With high resolution lenticular arrays, the lenses are very small, and some printing processes do not guarantee perfect placement accuracy between the different ink layers. This problem also arises for other devices of the same family, which can be grouped under the general name of printed optical circuits. The present invention solves this problem and opens the way for many applications of lenticular arrays and other high resolution printed optical circuits that were impossible until now. The proposed method is a printed optical circuit manufacturing method, consisting of creating transparent protuberances 11, 12, 13 and following by the deposition of a liquid substance on a media 10, then rendering this solid substance by any known means. such as cooling, drying or polymerization; and subsequently depositing a layer Cn + 1 of liquid substance on different parts of said media 10. According to other characteristics of the invention: a Cn ink layer is deposited + 1 on the entire surface having protruding lenses, and that the Cn + 1 layer is cleaned before rendering it solid, so that it occupies only substantially the surface 20 situated between said protuberances; The cleaning of the layer Cn + 1 is done with a known cleaning means rigid enough not to touch the spaces between the protuberances; Said layer Cn + 1 is black;

• les protubérances sont des lentilles convergentes ; • les lentilles convergentes sont des lentilles sphériques ayant une pupille en forme d'hexagone. L'invention sera bien comprise, et d'autres buts, avantages et caractéristiques de celle-ci apparaîtront plus clairement à la lecture de la description qui va suivre, laquelle est illustrée par la figure 1. La figure 1 est une vue en perspective d'un dispositif réalisé par un procédé selon l'invention. On distingue le média 10, des lentilles élémentaires sphériques 11, 12, 13 et suivantes, et une surface noire 20 ayant reçu l'impression d'une couche noire. La présente invention permet de réaliser des réseaux lenticulaires à haute résolution même avec des systèmes d'impression ne comportant pas une bonne qualité de repérage entre les couches d'encre successives. Le principe de base consiste à déposer une couche d'encre Cn+l sur les lentilles protubérances réalisées par une couche Cn, et à nettoyer cette couche Cn+l avant de la rendre solide, de telle sorte qu'elle n'occupe plus que sensiblement la surface 20 située entre les protubérances. Le nettoyage se fait de préférence avec une raclette souple, un chiffon ou une éponge, ce qui laisse une certaine quantité d'encre aux endroits difficilement accessibles, c'est-à-dire au fond des espaces séparant les protubérances transparentes. Les protubérances peuvent avantageusement être des lentilles convergentes cylindriques ou sphériques, et le circuit optique est dans ce cas un réseau lenticulaire. • the protuberances are convergent lenses; • Convergent lenses are spherical lenses with a hexagon-shaped pupil. The invention will be well understood, and other objects, advantages and characteristics thereof will appear more clearly on reading the description which follows, which is illustrated in FIG. 1. FIG. 1 is a perspective view of FIG. a device produced by a method according to the invention. Media 10, spherical elementary lenses 11, 12, 13 and following, and a black surface 20 having the impression of a black layer are distinguished. The present invention makes it possible to produce lenticular networks with high resolution even with printing systems that do not have a good quality of identification between the successive ink layers. The basic principle is to deposit a layer of ink Cn + 1 on the protruding lenses made by a layer Cn, and to clean this layer Cn + 1 before making it solid, so that it occupies only substantially the surface 20 located between the protuberances. The cleaning is preferably done with a flexible squeegee, a cloth or a sponge, which leaves a certain amount of ink in hard to reach places, that is to say at the bottom of the spaces separating the transparent protuberances. The protuberances may advantageously be cylindrical or spherical convergent lenses, and the optical circuit is in this case a lenticular array.

Pour minimiser l'espace entre des lentilles transparentes sphériques, il est avantageux de leur donner la forme d'hexagones. Les principales applications de la présente invention sont principalement celles de l'impression de tous matériaux, et en particulier la fabrication de réseaux lenticulaires. To minimize the space between spherical transparent lenses, it is advantageous to give them the shape of hexagons. The main applications of the present invention are mainly those of the printing of all materials, and in particular the manufacture of lenticular networks.
