Abstract
Description
La présente invention concerne une plaque d'impression taille-douce, utilisée par exemple pour l'impression de papiers-valeurs comme des billets de banque, chèques et autres documents similaires.The present invention relates to an intaglio printing plate, used by example for printing securities such as banknotes, checks and other similar documents.
La technique de l'impression taille-douce est bien connue dans l'état de la technique, notamment pour l'impression de papiers-valeurs. Selon cette technique, une plaque d'impression est gravée pour former un dessin prédéterminé et les gravures sont ensuite remplies d'encre qui sera reportée sur le support imprimé, par exemple du papier, qui est déformé par pression au moyen d'un cylindre, ayant une surface élastique, dans les gravures de la plaque. La surface du papier qui pénètre dans les gravures est ainsi marquée avec l'encre qui a été déposée auparavant dans lesdites gravures.The technique of intaglio printing is well known in the state of the art, especially for printing securities. According to this technique, a plate print is etched to form a predetermined pattern and the etchings are then filled with ink which will be transferred to the printed medium, for example paper, which is deformed by pressure by means of a cylinder, having an elastic surface, in the plate engravings. The surface of the paper entering the engravings is thus marked with ink which was previously deposited in said engravings.
Les brevets US 5,062,359 et US 5,899,145 décrivent des machines d'impression utilisant le procédé d'impression taille-douce. Leur contenu est incorporé par référence à la présente demande pour ce qui concerne le principe du procédé d'impression et les moyens nécessaires à sa réalisation.US Patents 5,062,359 and US 5,899,145 describe printing machines using the intaglio printing process. Their content is incorporated by reference to the present application with regard to the principle of the printing process and the means necessary for its realization.
A titre d'exemple de réalisation d'une plaque d'impression taille-douce, référence est faite au brevet US 4,036,130 dont le contenu est incorporé par référence dans la présente demande. Une telle plaque, habituellement en métal, est gravée pour former un dessin déterminé et peut recevoir une couche supplémentaire durcie. En outre, la demande DE 196 24 131 décrit un autre procédé automatisé de fabrication de plaque d'impression taille-douce au moyen d'un laser.As an example of an intaglio printing plate, reference is made to US Patent 4,036,130, the content of which is incorporated by reference into the this request. Such a plate, usually made of metal, is engraved to form a determined design and can receive an additional hardened layer. In addition, the application DE 196 24 131 describes another automated plate manufacturing process intaglio printing using a laser.
La demande de brevet DE 198 45 440 montre une autre réalisation de plaques d'impression taille-douce pour une impression à plat, les plaques décrites comprenant des gravures dont le fond présente des séparations formant des canaux ou chambres permettant le transfert de l'encre dans un sens vertical seulement, c'est-à-dire perpendiculaire à la surface de la plaque, et non dans un sens horizontal ou diagonal. Patent application DE 198 45 440 shows another production of plates intaglio printing unit for flatbed printing, the described plates comprising engravings the bottom of which has partitions forming channels or chambers allowing the ink to be transferred in a vertical direction only, i.e. perpendicular to the surface of the plate, and not in a horizontal or diagonal direction.
Ces canaux permettent également la modulation de l'épaisseur de l'encre déposée sur le support imprimé.These channels also allow modulation of the thickness of the ink deposited on the printed medium.
Finalement, la demande de brevet DE 198 45 436 décrit un procédé d'impression taille-douce, dans lequel l'intensité d'une même couleur imprimée varie. Cet effet est obtenu par une gravure de la plaque dont la profondeur varie de telle façon que la quantité d'encre dans la gravure varie elle-aussi de telle sorte que la quantité d'encre reportée sur le substrat imprimé est différente, créant ainsi des intensités variables.Finally, patent application DE 198 45 436 describes an intaglio printing process, in which the intensity of the same printed color varies. This effect is obtained by engraving the plate, the depth of which varies so that the quantity of ink in the engraving also varies so that the quantity of ink transferred to the printed substrate is different, thus creating varying intensities.
L'un des problèmes rencontrés avec les plaques d'impression utilisées dans la technique d'impression taille-douce dans les machines d'impression rotatives est lié à la vitesse de rotation desdites plaques qui sont montées sur des cylindres porte-plaques, telle que décrit dans le brevet US 4,598,642 dont le contenu est incorporé par référence dans la présente demande.One of the problems encountered with printing plates used in the art of intaglio printing in rotary printing machines is related to the speed of rotation of said plates which are mounted on plate cylinders, such as described in US Patent 4,598,642, the content of which is incorporated by reference into the this request.
La cadence de production de ces machines d'impression taille-douce peut s'élever jusqu'à 10'000 feuilles par heure ce qui, typiquement, correspond à une vitesse linéaire de 2,8 mètres/seconde. L'encre déposée dans les tailles de la plaque subit donc plusieurs forces, l'une perpendiculaire au sens de déplacement de la plaque, et l'autre centrifuge en raison de la rotation de la plaque autour de l'axe du cylindre porte-plaque.The production rate of these intaglio printing machines can go up up to 10,000 sheets per hour which typically corresponds to a linear speed 2.8 meters / second. The ink deposited in the sizes of the plate therefore undergoes several forces, one perpendicular to the direction of movement of the plate, and the other centrifugal due to the rotation of the plate around the axis of the plate cylinder.
En conséquence, l'encre va se déplacer vers l'arrière de la taille dans la plaque par rapport au sens de rotation et va en plus être attirée vers l'extérieur de la taille au lieu de rester au fond de celle-ci, ce qui a pour effet une impression de moindre qualité et un encrage irrégulier du papier.As a result, the ink will move backwards from the waist into the plate by relative to the direction of rotation and will also be drawn outside the waist instead of stay at the bottom of it, which results in a lower quality print and a irregular paper inking.
Le but de l'invention est de remédier à ces inconvénients en améliorant les plaques d'impressions connues.The object of the invention is to remedy these drawbacks by improving the plates of known impressions.
Plus particulièrement, l'un des buts de l'invention est de proposer une plaque d'impression taille-douce permettant un encrage de qualité malgré le fait que l'encrage se fait dans un système en mouvement. More particularly, one of the aims of the invention is to propose a plate intaglio printing allowing quality inking despite the fact that inking is done in a moving system.
La plaque selon l'invention est définie par les caractéristiques contenues dans les revendications.The plate according to the invention is defined by the characteristics contained in the claims.
L'invention sera mieux comprise par la description d'un mode d'exécution de celle-ci et des figures qui s'y rapportent.The invention will be better understood by the description of an embodiment thereof and related figures.

efficacement aux effets de la résultante f12 telle que représentée dans la figure 1.In FIG. 2, the first embodiment of the ink retaining means 4 are
represented. These means have the form of
Un autre mode d'exécution des moyens de retenue est représenté dans la figure 3. Dans
ce mode de réalisation, les moyens prennent la forme d'une denture 7 taillée dans la
partie arrière de la gravure 3 par rapport au sens de rotation R de la plaque 1.Another embodiment of the retaining means is shown in Figure 3. In
this embodiment, the means take the form of a toothing 7 cut in the
rear part of the engraving 3 relative to the direction of rotation R of the
Selon le mode d'exécution de la figure 4, les moyens de retenue ont la forme de creux 8
répartis dans la gravure 3, sur sa partie arrière par rapport au sens de rotation R de la
plaque 1.According to the embodiment of Figure 4, the retaining means have the shape of a hollow 8
distributed in engraving 3, on its rear part relative to the direction of rotation R of the
Bien entendu, il est possible de combiner ces différents modes d'exécution de moyens
de retenue, ou encore de varier la taille des créneaux 6, denture 7 ou creux 8 en fonction
de leur position dans la gravure, voire encore de combiner différentes formes
géométriques pour optimiser la retenue de l'encre sur une plaque 1, le but étant de
s'opposer aux effets de la résultante f12.Of course, it is possible to combine these different modes of execution of means
to retain, or to vary the size of the
