Description
La présente invention se rapporte au domaine technique du séchage de gouttes d'encre après impression sur un support d'impression et plus particulièrement lors d'une impression point par point d'encre à base d'eau ou de solvant.The present invention relates to the technical field of drying ink drops after printing on a printing medium and more particularly when printing dot by dot water-based ink or solvent.
Lors de l'impression d'un motif sur un support d'impression, et notamment lors d'une impression jet d'encre point par point, il est important de contrôler le durcissement des gouttes d'encre et ce particulièrement lorsque le support d'impression a un faible pouvoir absorbant. Sur ce type de support d'impression, les gouttes d'encre en fonction de leur viscosité peuvent être absorbées plus ou moins vite ou encore s'étaler et se mélanger entres elles sur leur périphérie, ce qui peut entrainer une perte de qualité de l'impression plus particulièrement lorsqu'il s'agit d'une impression couleur.When printing a pattern on a print media, and especially for point-by-point inkjet printing, it is important to control the hardening of ink drops, especially when printing has a low absorbency. On this type of printing medium, the ink drops as a function of their viscosity can be absorbed more or less quickly or spread out and mix with each other on their periphery, which can cause a loss of quality of the ink. especially when it comes to color printing.
Pour remédier à ces inconvénients, il est connu pour des encres polymérisables sous radiation ultraviolette d'utiliser un dispositif de polymérisation permettant une exposition au rayonnement ultraviolet point par point au niveau des points où les gouttes d'encre sont relâchées sur le support d'impression afin de contrôler le durcissement desdites gouttes d'encre. Un tel dispositif est par exemple décrit dans le brevet
Cependant, pour les encres à base d'eau ou de solvants, les dispositifs de contrôle du durcissement actuellement utilisés jouent sur le temps de séchage des gouttes d'encre ce qui augmente le temps d'impression et les coûts.However, for water-based or solvent-based inks, the hardening control devices currently in use affect the drying time of the ink drops, which increases printing time and costs.
Un des buts de l'invention est donc de remédier au moins partiellement aux inconvénients de l'art antérieur et de proposer un dispositif de séchage de gouttes d'encre à base d'eau ou de solvant amélioré.One of the aims of the invention is therefore to at least partially overcome the drawbacks of the prior art and to propose a device for drying ink drops based on water or an improved solvent.

Du fait de la présence d'une source d'émission d'un faisceau infrarouge et d'un dispositif de guidage, le dispositif de séchage permet un séchage rapide et économique des gouttes d'encre directement au niveau des points d'encre, ainsi qu'un contrôle de la viscosité de ces mêmes gouttes d'encre permettant une amélioration de la qualité de l'impression en elle-même.Due to the presence of an infrared beam emission source and a guiding device, the drying device allows fast and economical drying of the ink drops directly at the ink dots, as well as a control of the viscosity of these same drops of ink to improve the quality of the printing itself.

L'utilisation d'un laser infrarouge permet une exposition au rayonnement infrarouge d'une zone d'exposition réduite et précise.The use of an infrared laser allows exposure to infrared radiation of a reduced and precise exposure area.
Selon un autre aspect de l'invention, le dispositif de guidage du faisceau de lumière infrarouge comporte au moins un réflecteur à l'aplomb de la surface du support d'impression.According to another aspect of the invention, the device for guiding the infrared light beam comprises at least one reflector plumb with the surface of the printing medium.
Selon un autre aspect de l'invention, le réflecteur est orientable.According to another aspect of the invention, the reflector is orientable.

La présente invention concerne également une imprimante jet d'encre comportant un dispositif de séchage comme décrit précédemment.The present invention also relates to an ink jet printer comprising a drying device as described above.

Le dispositif de séchage 1 comporte une source d'émission 5 d'un faisceau de lumière infrarouge 50 ainsi qu'un dispositif de guidage 7 dudit faisceau de lumière infrarouge 50. Les points d'encre 31, 32, 32 sont, lors de dépôt sur le support d'impression 3, caractérisé par une localisation précise afin de reproduire fidèlement le motif à imprimer. Cette localisation se traduit par des coordonnées de positionnement desdits points d'encre 31, 32, 33 sur le support d'impression 3 qui peuvent être utilisées par le dispositif de guidage 7 afin de guider le faisceau de lumière infrarouge 50 sur une zone d'exposition 51 correspondante.The
Du fait de la localisation précise des différents points d'encre 31, 32, 33, le dispositif de guidage 7 peut guider directement le faisceau de lumière infrarouge 50 sur les points d'encre à exposer sans pour autant exposer les zones non encrées entre lesdits points d'encre 31, 32, 33, ce qui diminue les risques de vieillissement ou jaunissement de ces zones non encrées du fait de leur exposition à un rayonnement infrarouge.Due to the precise location of the
Cette localisation précise de la zone d'exposition 51 où le faisceau de lumière infrarouge 50 doit être dirigé, permet de réduire également la consommation d'énergie nécessaire pour le séchage de l'impression. En effet, seuls les points d'encre 31,32 et 33 sont irradiés.This precise location of the
De plus, le fait de connaitre précisément la localisation des points d'encre 31, 32, 33 permet un balayage rapide et direct de ces derniers au moyen du dispositif de guidage 7. Ainsi l'impact en temps du séchage sur l'impression est limité.In addition, the fact of knowing precisely the location of the
Afin de concentrer le faisceau de lumière infrarouge 50 sur une zone d'exposition 51 réduite et correspondant le plus possible à la taille d'un point d'encre, le dispositif de séchage peut comporter un concentrateur (non représenté) comme par exemple une loupe ou encore, le faisceau de lumière infrarouge 50 peut être un laser infrarouge qui permet une exposition au rayonnement infrarouge d'une zone d'exposition 51 réduite et précise.In order to focus the
Pour n'exposer que les points d'encre 31, 32, 33, la source d'émission 5 du faisceau de lumière 50 peut être impulsive ou bien le dispositif de séchage 1 peut comporter un obturateur 54 qui permet de ne laisser passer le faisceau de lumière 50 que lorsque que ce dernier exposera la zone d'exposition 51 désirée.To expose only the
Le fait d'exposer les gouttes d'encre au niveau des points d'encre 31, 32, 33 à un faisceau de lumière infrarouge, permet de sécher totalement ou partiellement lesdites gouttes d'encre par évaporation de l'eau ou des solvants que l'encre contient. Ainsi il est possible de contrôler la viscosité de la goutte d'encre après son dépôt sur le support d'impression 3. Ce contrôle de la viscosité de la goutte d'encre sur le point d'encre permet notamment de contrôler son étalement cela a comme avantage de pouvoir faire diminuer la consommation d'encre par une meilleure gestion de l'étalement.The fact of exposing the ink drops at the
De plus le contrôle de la viscosité permet une gestion de la finition et de l'aspect de l'impression. En effet, un séchage total, rapidement effectué après le dépôt de la goutte d'encre sur le support d'impression, permet de conserver une forme relativement demi-sphérique de cette dernière et permet ainsi d'obtenir un aspect de finition mat de l'impression finale. A contrario, un séchage partiel ou effectué plus tardivement permet à la goutte d'encre de s'étaler sur le support d'impression 3 et d'obtenir un aspect de finition brillant de l'impression finale.In addition, viscosity control allows management of the finish and appearance of the print. Indeed, a total drying, quickly carried out after the deposit of the ink drop on the printing medium, makes it possible to maintain a relatively semispherical shape of the latter and thus makes it possible to obtain a matte finish appearance of the ink. final impression. On the other hand, partial or later drying allows the ink drop to spread over the
Le contrôle de la viscosité et de l'étalement des gouttes d'encre permet également de diminuer des risques de contact et de mélange entre deux gouttes proches. Ainsi, les risques de mélange en périphérie entre deux gouttes sont réduits, cela est notamment avantageux dans le cas d'une impression polychromatique où les gouttes de couleur différente pourraient se mélanger en périphérie et diminuer la qualité de l'impression.The control of the viscosity and the spreading of the ink drops also makes it possible to reduce the risks of contact and of mixing between two close drops. Thus, the risks of mixing at the periphery between two drops are reduced, this is particularly advantageous in the case of a polychromatic printing where the drops of different color could mix at the periphery and reduce the quality of printing.
Afin de moduler la puissance du faisceau de lumière infrarouge 50, le dispositif de séchage, et plus particulièrement la source d'émission 5, peut avantageusement comporter un variateur de puissance (non représenté) ou bien, le dispositif de séchage 1 peut comporter un modulateur optique de type lame de diffraction orientable (non représenté).In order to modulate the power of the

Selon une première variante, l'angle de réflexion varie continuellement et le faisceau de lumière infrarouge 50 n'est projeté sur le réflecteur 70 orientable que lorsqu'il est en position pour le réfléchir en direction d'une zone d'exposition 51 désirée.According to a first variant, the angle of reflection varies continuously and the
Selon une seconde variante, l'angle de réflexion varie uniquement en fonction des zones d'exposition à atteindre. Le balayage est donc discontinu et le réflecteur 70 orientable passe d'une position à une autre sans transition.According to a second variant, the angle of reflection varies only according to the exposure zones to be reached. The scanning is discontinuous and the
L'étalement du faisceau de lumière infrarouge 50 sur le support d'impression 3 du faite de son angle d'incidence peut être corrigé au moyen par exemple d'une optique de correction dite à champ plat afin d'avoir une zone d'exposition 51 qui ne recouvre que les points d'encre 31, 32, 33.The spreading of the

Cette première variante convient particulièrement aux impressions par jet d'encre qui permettent une impression ligne par ligne. Les imprimantes capables de ce genre d'impression comportent généralement une barrette 110 linéaire de générateurs de gouttes d'encre. Une série de goutte d'encre 20 est émise simultanément en direction des points du support à encrer. De tels imprimantes sont notamment utilisées en impression offset polychrome et disposent de plusieurs barrettes 110, 120, 130 génératrices alimentées par des réservoirs 119, 129, 139 d'encres de couleurs différentes.This first variant is particularly suitable for inkjet printing which allows line-by-line printing. Printers capable of this kind of printing generally comprise a

Ainsi, on voit bien que le dispositif de séchage 1 de gouttes d'encre à base d'eau ou de solvant selon l'invention permet, de par la présence d'une source d'émission 5 d'un faisceau infrarouge 50 et d'un dispositif de guidage 7, un séchage rapide et économique des gouttes d'encre 20 directement au niveau des points d'encre 31, 32, 33, ainsi qu'un contrôle de la viscosité de ces mêmes gouttes d'encre 20 permettant une amélioration de la qualité de l'impression en elle-même.Thus, it can clearly be seen that the
