Description
L'invention concerne une feuille à bord(s) frangé(s) couchée, imprimable destinée au procédé d'impression par jet d'encre. L'invention concerne plus particulièrement une feuille à bord(s) frangé(s) couchée avec une couche pigmentée qui présente une bonne imprimabilité en impression par jet d'encre. L'invention concerne également le procédé de fabrication d'une telle feuille.The present invention relates to a printable fringed edge sheet (s) for the ink jet printing process. The invention more particularly relates to a sheet with fringed edge (s) coated with a pigmented layer which has good printability in ink jet printing. The invention also relates to the method of manufacturing such a sheet.
Panni les techniques d'impression suffisamment souples pour obtenir de petites quantités à la demande, l'impression par jet d'encre s'est avérée être la technique la plus adaptée aux besoins des feuilles à bords frangés. Outre la simplicité de son principe de fonctionnement, l'impression par jet d'encre permet d'obtenir des impressions en couleur. Toutefois, l'impression par jet d'encre de feuilles telles que des papiers engendre des problèmes liés au principe d'impression par jet d'encre lui-même qui sont les suivants :
- le temps de séchage de l'encre est long du fait que le véhicule de l'encre est un milieu aqueux,
- un manque d'homogénéité des couleurs ("mottling"), c'est-à-dire un aspect nuageux observé à certains endroits, que ce soit pour une couleur unique ou pour une association de couleurs,
- la présence de bavures, c'est-à-dire une couleur qui déborde du support ou des couleurs qui débordent l'une sur l'autre,
- une trop faible intensité des couleurs,
- une trop faible résolution des impressions,
- une mauvaise résistance à l'eau des impressions, c'est-à-dire que les , impressions ne résistent pas bien lorsque le support est mouillé,
- un transpercement de l'encre à travers la feuille.
- the ink drying time is long because the vehicle of the ink is an aqueous medium,
- a lack of color homogeneity ("mottling"), that is to say a cloudy aspect observed in certain places, whether for a single color or for a combination of colors,
- the presence of burrs, that is to say a color that overflows the support or colors that overlap one another,
- too low color intensity,
- too low resolution of impressions,
- poor print water resistance, that is, the prints do not resist well when the substrate is wet,
- a piercing of the ink through the sheet.
Comme la technique d'impression par jet d'encre repose sur le principe d'une fixation d'encre à la surface du support à imprimer, le support à imprimer doit par conséquent avoir une absorption limitée afin d'obtenir une impression nette et de haute qualité.Since the inkjet printing technique is based on the principle of fixing ink on the surface of the print medium, the print medium must therefore have a limited absorption in order to obtain a clean impression. high quality.
Afin de résoudre les problèmes précédemment cités, des supports améliorés par une enduction de leur surface avec une couche imprimable par jet d'encre ont été proposés. En effet, il est connu de l'état de la technique que les propriétés d'imprimabilité d'une feuille fibreuse, à base de fibres naturelles et/ou synthétiques, sont améliorées par le couchage en surface de ladite feuille d'une composition pigmentée comprenant des particules fixatrices d'encre (
Toutefois, les feuilles à bords frangés actuellement commercialisées comme, par exemple, les papiers aquarelles à bords frangés, sont des papiers à deux, voire quatre, bords frangés exempts de couche pigmentée, en particulier exempts de toute couche pigmentée spécifique à l'impression par jet d'encre.However, the currently marketed fringed leaves such as, for example, watercolor papers with fringed edges, are papers with two or even four fringed edges free of pigmented layer, in particular free of any pigmented layer specific to printing by inkjet.
L'application d'une couche pigmentée pour impression par jet d'encre en surface d'une feuille à bords frangés a jusqu'à présent été considérée par l'Homme du Métier comme ne pouvant générer que de nombreux problèmes de fabrication dus aux feuilles à bords frangés elles-mêmes. Quelques-uns de ces divers problèmes sont énumérés ci-dessous :
- l'application d'une couche imprimable par jet d'encre en surface d'un support, comme par exemple une feuille de papier, à bords frangés générerait des surépaisseurs ou des irrégularités de surface indésirables notamment en bordure du support. En effet, l'Homme du Métier pensait que la couche ne serait pas répartie de façon homogène, les bords du support (ou feuille de papier) étant revêtus plus fortement par la composition de la couche compte-tenu de la présence de franges;
- un tel support revêtu d'une couche imprimable ne présenterait alors pas le même lissé de surface sur toute sa surface de par la non-homogénéité de répartition de la couche fixatrice d'encre (présence de zones à forte ou faible concentration de composition de couche), ceci s'avérant incompatible avec les qualités requises pour un support destiné à un procédé d'impression par jet d'encre où la couche de surface joue un rôle fondamental dans le rendu d'impression;
- par ailleurs, l'Homme du Métier pensait que l'application d'une couche de surface, notamment imprimable par jet d'encre, sur un support à bords frangés engendrerait des relargages de fibres sur les bords dudit support provoquant ainsi une pollution de la couche du fait de la présence de débris de fibres; ceci serait particulièrement gênant lors de la fabrication dudit papier couché à bords frangés pour lequel on recherche de bonnes caractéristiques de rendu d'impression et de surface ;
- de plus, l'Homme du Métier utilisant traditionnellement pour les couches pigmentées un dispositif de couchage à lame métallique, pensait qu'un tel dispositif couchage pouvait être à l'origine de nombreuses casses. Pour l'Homme du Métier, les contraintes mécanique de pression et de tension importantes lors du contact de la lame métallique avec la feuille seraient particulièrement gênantes lors du couchage sachant que les bords frangés proviennent de zones de moindre épaisseur (déficit de matière) réalisées dans la feuille lors de sa fabrication.
- the application of an inkjet printable layer on the surface of a support, such as for example a sheet of paper, with fringed edges would generate undesirable thickenings or surface irregularities notably at the edge of the support. Indeed, the skilled person thought that the layer would not be homogeneously distributed, the edges of the support (or paper sheet) being coated more strongly by the composition of the layer taking into account the presence of fringes;
- such a support coated with a printable layer would then not have the same surface smoothness over its entire surface due to the non-homogeneous distribution of the ink-fixing layer (presence of zones with a high or low concentration of layer composition ), this being incompatible with the qualities required for a support for an inkjet printing process where the surface layer plays a fundamental role in the print rendering;
- Moreover, the skilled person thought that the application of a surface layer, especially inkjet printable, on a fringed-edge support would cause the release of fibers on the edges of said support thus causing pollution of the surface. layer due to the presence of fiber debris; this would be particularly troublesome during the manufacture of said coated paper with fringed edges for which good looking print and surface characteristics are sought;
- Moreover, the skilled person traditionally using for the pigmented layers a coating device metal blade, thought that such a sleeping device could be at the origin of many breaks. For the skilled person, the mechanical stresses of pressure and tension during the contact of the metal blade with the sheet would be particularly troublesome during the coating knowing that the fringed edges come from areas of lesser thickness (material deficit) made in the sheet during its manufacture.

Compte-tenu de ce qui précède, les feuilles à bords frangés sont traditionnellement dans l'industrie papetière soumises à une opération de découpe des bords frangés, encore appelée « rognure des bords », de sorte à éliminer ces bords pour obtenir des feuilles à bords droits et bien nets, et ce préalablement à toute opération de couchage destinée à améliorer l'imprimabilité de la feuille. En effet, le dépôt d'une couche fixatrice d'encre a toujours été jusqu'à présent réalisée sur une feuille à bords droits, c'est-à-dire une feuille dont les bords frangés ont été rognés avant l'opération de couchage.In view of the above, the leaves with fringed edges are traditionally in the paper industry subjected to a fringed edge cutting operation, also called "edge trimming", so as to eliminate these edges to obtain leaves with edges right and clear, and this prior to any coating operation to improve the printability of the sheet. Indeed, the deposition of an ink-fixing layer has always been carried out so far on a straight-edged sheet, that is to say a sheet whose fringed edges have been trimmed before the coating operation. .
La présente invention se propose donc de fournir un support d'impression à bord(s) frangé(s) imprimable par jet d'encre, c'est-à-dire présentant les qualités requises pour les impressions par jet d'encre en terme de rendu d'impression, de temps de séchage de l'encre et d'intensité et d'homogénéité des couleurs.The present invention therefore proposes to provide a fringe printing medium (s) printable by inkjet, that is to say having the qualities required for inkjet printing in term print rendering, ink drying time, and color intensity and homogeneity.
Selon un premier aspect, l'invention réside dans une feuille à bord(s) frangé(s) revêtue d'une couche fixatrice d'encre appropriée pour obtenir une bonne imprimabilité par jet d'encre (donc couchée) et ayant un format déterminé, par exemple, de formant A4, c'est-à-dire une feuille à bord(s) frangé(s) couchée, imprimable par jet d'encre.According to a first aspect, the invention lies in a sheet with fringed edge (s) coated with a suitable ink-fixing layer to obtain good printability by ink jet (thus coated) and having a given format. , for example, forming A4, that is to say a sheet with fringe (s) lying (s), printable by ink jet.
Selon un deuxième aspect, l'invention vise à résoudre les problèmes de couchage des feuilles à bord(s) frangé(s) en proposant un procédé de fabrication d'une feuille à bord(s) frangé(s) couchée, imprimable par jet d'encre, dans lequel une feuille avec au moins un bord(s) frangé(s) est traitée en surface avec une couche fixatrice d'encre. Le procédé de fabrication d'une telle feuille selon la présente invention va à l'encontre des préjugés de l'Homme du Métier.According to a second aspect, the invention aims to solve the problems of coating sheets with fringed edge (s) by proposing a method of manufacturing a sheet with fringed edge (s) lying, printable by jet in which a sheet with at least one fringe edge (s) is surface-treated with an ink-fixing layer. The method of manufacturing such a sheet according to the present invention goes against the prejudices of the skilled person.
L'invention concerne donc une feuille à bord(s) frangé(s) imprimable par jet d'encre, couchée qui comprend un support avec au moins un bord(s) frangé(s) recouvert, sur au moins l'une de ses faces, d'au moins une couche pigmentée fixatrice d'encre pour impression jet d'encre.The invention thus relates to an ink-coated, ink-coated fringed edge sheet (s) which comprises a support with at least one fringed edge (s) covered, on at least one of its at least one ink-fixing pigment-fixing layer for ink-jet printing.
Selon un mode de réalisation de l'invention, la couche pigmentée fixatrice d'encre a un poids compris entre 3 et 30 g/m2 en poids sec par face. Plus particulièrement, le poids de ladite couche pigmentée est compris entre 5 et 15 g/m2 en sec, par face. Selon l'invention, la couche pigmentée fixatrice d'encre, qui est une couche de surface imprimable, comporte au moins un liant et au moins un pigment de couchage.According to one embodiment of the invention, the pigment-fixing ink-fixing layer has a weight of between 3 and 30 g / m 2 by dry weight per side. More particularly, the weight of said pigmented layer is between 5 and 15 g / m 2 in sec, per side. According to the invention, the ink-fixing pigment layer, which is a printable surface layer, comprises at least one binder and at least one coating pigment.
A titre de liant de la couche pigmentée, on peut citer les liants choisis parmi l'alcool polyvinylique (PVA), la polyvinylpyrrolidone, l'amidon, les liants polymères utilisés en dispersion aqueuse stabilisée (latex) et usuels des couches fixatrices d'encre ou du domaine papetier comme, par exemple, les copolymères styrène/butadiène, styrène/acrylique, éthylène/vinyle acétate/chlorure de vinyle, pris seuls ou en mélange.As binder of the pigmented layer, mention may be made of the binders chosen from polyvinyl alcohol (PVA), polyvinylpyrrolidone, starch, the polymeric binders used in stabilized aqueous dispersion (latex) and customary ink-fixing layers. or the paper industry such as, for example, styrene / butadiene, styrene / acrylic, ethylene / vinyl acetate / vinyl chloride copolymers, alone or in admixture.
Les pigments de ladite couche pigmentée fixatrice d'encre peuvent être choisis parmi les pigments minéraux tels que les carbonates de calcium, les kaolins, le talc, le dioxyde de titane, les pigments plastiques, la silice, les oxydes d'aluminium, pris seuls ou en mélange.The pigments of said pigment-fixing ink-fixing layer may be chosen from mineral pigments such as calcium carbonates, kaolin, talc, titanium dioxide, plastic pigments, silica, aluminum oxides, taken alone. or in mixture.
Dans le cas particulier de l'invention où les pigments minéraux de couchage sont transparents ou translucides, notamment des silices amorphes telles que, par exemple, des silices amorphes de précipitation ou de pyrogénation ayant une surface spécifique supérieure à 100 m2/g, le support peut être coloré en masse et/ou en surface, la coloration restant maintenue visible à travers ladite couche pigmentée.In the particular case of the invention in which the inorganic coating pigments are transparent or translucent, especially amorphous silicas such as, for example, amorphous precipitating or pyrogenic silicas having a specific surface area greater than 100 m 2 / g, the The support may be colored in bulk and / or on the surface, the coloration remaining visible through said pigmented layer.
Selon un mode de réalisation préféré de l'invention, le support à au moins un bord frangé est un papier à base de fibres de cellulose, en particulier de coton, éventuellement en mélange avec des fibres synthétiques et/ou minérales.According to a preferred embodiment of the invention, the support with at least one fringed edge is a paper based on cellulose fibers, in particular cotton, optionally mixed with synthetic and / or mineral fibers.
De préférence, ledit support fibreux est choisi parmi les papiers à base essentiellement de fibres de coton, en particulier les papiers aquarelles.Preferably, said fibrous support is chosen from papers based essentially on cotton fibers, in particular watercolor papers.
Selon un cas particulier de réalisation de l'invention, le support fibreux avec au moins un bord frangé peut être fabriqué sur une machine à papier de forme ronde, puis être couché hors machine par tout dispositif de couchage usuel en papeterie.According to a particular embodiment of the invention, the fibrous support with at least one fringed edge may be manufactured on a round-shaped paper machine, and then be laid out of the machine by any usual paper coating device.
De préférence, ledit support fibreux avant couchage est un support fibreux avec deux bords frangés, qui peut présenter à l'issue de sa formation sur la machine à papier des zones de moindre épaisseur de fibres dans le sens travers de la machine. Ledit support, après l'opération de couchage hors machine, donne alors un support fibreux couché à deux bords frangés qui conduira :
- soit, à une feuille à deux bords frangés couchée, imprimable par jet d'encre lorsqu'une opération de découpe droite et nette est réalisée au niveau desdites zones de moindre épaisseur présentes dans le sens travers du support pour donner des feuilles formatées à deux bords frangés selon l'invention,
- soit à une feuille à quatre bords frangés couchée, imprimable par jet d'encre, lorsqu'une rupture du support au niveau de ses zones de moindres épaisseurs dans le sens travers est réalisée par un réglage particulier de la coupeuse pour donner des feuilles formatées à quatre bords frangés selon l'invention.
- or, to a sheet with two fringed edges lying down, printable by ink jet when a straight and sharp cutting operation is performed at said areas of least thickness present in the cross-direction of the support to give formatted sheets with two edges fringed according to the invention,
- or to a sheet with four fringed edges coated, ink jet printable, when a rupture of the support at its areas of least thickness in the cross direction is achieved by a particular setting of the cutter to give sheets formatted to four fringed edges according to the invention.
L'invention concerne en outre un procédé de fabrication d'une feuille à bord(s) frangé(s) imprimable par jet d'encre, couchée comportant les étapes suivantes :
- a) on forme sur une machine à papier un support fibreux ayant au moins un bord frangé, puis

Selon le procédé de fabrication d'une feuille à bord(s) frangé(s) de l'invention, on peut former lors d'une première étape un support fibreux avec au moins un bord frangé par voie papetière sur une machine à papier de forme ronde à partir d'une dispersion aqueuse de fibres de cellulose, en particulier de coton, éventuellement en mélange avec des fibres synthétiques et/ou minérales, et éventuellement d'autres additifs comme des liants tels que l'amidon, l'alcool polyvinylique, la carboxyméthyl cellulose, des charges, des agents de rétention, des colorants. Selon un cas particulier, le support ayant au moins un bord frangé peut être constitué essentiellement de fibres de coton.According to the method of manufacturing a sheet with fringed edge (s) of the invention, it is possible to form, in a first step, a fibrous support with at least one fringed edge by papermaking on a paper machine of round shape from an aqueous dispersion of cellulose fibers, in particular of cotton, optionally in mixing with synthetic and / or mineral fibers, and optionally other additives such as binders such as starch, polyvinyl alcohol, carboxymethyl cellulose, fillers, retention agents, dyes. In a particular case, the support having at least one fringed edge may consist essentially of cotton fibers.
De préférence, on forme sur une machine à papier de forme ronde, à partir d'une dispersion aqueuse de fibres cellulosiques, un support à deux bords frangés, en particulier un papier aquarelle avec deux bord(s) frangé(s), et présentant des zones de moindre épaisseur de fibres dans le sens travers de la machine.Preferably, a support with two fringed edges, in particular a watercolor paper with two fringes (s), and presenting areas of less fiber thickness in the cross machine direction.
Selon le procédé de l'invention, dans une deuxième étape b), on dépose au moyen d'un dispositif de couchage sur au moins une des faces du support à bord(s) frangé(s) obtenue à l'issue de l'étape a) (appelée aussi « support avec au moins un bord frangé ») au moins une couche pigmentée (appelée aussi « couche fixatrice d'encre ») imprimable par jet d'encre.According to the method of the invention, in a second step b), it is deposited by means of a coating device on at least one of the faces of the support with fringed edge (s) obtained at the end of the step a) (also called "support with at least one fringed edge") at least one pigmented layer (also called "ink-fixing layer") printable by inkjet.
Ladite couche pigmentée appliquée sur le support obtenu à l'étape a) du procédé est une couche de surface telle que définie précédemment, fixatrice d'encre imprimable par jet d'encre et qui comporte au moins un liant et au moins un pigment de couchage.Said pigmented layer applied to the support obtained in step a) of the process is a surface layer as defined above, an ink jet printable ink fixator and which comprises at least one binder and at least one coating pigment .
Selon le procédé de l'invention, ledit support ayant au moins un bord frangé issu de l'étape a) peut être couché par tout dispositif de couchage habituellement utilisé en papeterie. On peut utiliser avantageusement une coucheuse à lame d'air ou un dispositif de couchage à rideau.According to the process of the invention, said support having at least one fringed edge resulting from step a) can be coated by any coating device usually used in stationery. Advantageously, an air knife coater or a curtain coating device may be used.
Selon une variante préférée de mise en oeuvre du procédé, le support fibreux issu de l'étape a) possède deux bords frangés qui sont obtenus par une rupture dudit support au niveau des zones de moindre épaisseur de fibres crées dans le sens marche de la machine à papier, zones préférentiellement au nombre de trois -à savoir proche de chacun des deux bords dudit support et dans sa zone médiane-, créant deux bandes de support à deux bords frangés de taille de laize identique. Le support fibreux à deux bords frangés alors obtenu, à l'issu de l'étape a), présente des zones de moindres épaisseur de fibres dans le sens travers de la machine.According to a preferred variant of implementation of the process, the fibrous support resulting from step a) has two fringed edges which are obtained by a rupture of said support at the level of the zones of lesser thickness of fibers created in the running direction of the machine. paper, zones preferably of the number of three-namely close to each of the two edges of said support and in its median zone-, creating two support strips with two fringed edges of identical size of width. The fibrous support with two fringed edges thus obtained, at the end of step a), has areas of least fiber thickness in the cross machine direction.
Après l'opération de couchage de l'étape b) du procédé, le support fibreux couché à deux bords frangés, qui présenté à l'issue de sa formation sur la machine à papier des zones de moindre épaisseur de fibres dans le sens travers, subit une opération de découpe pour donner des feuilles à bord(s) frangées) selon l'invention.After the coating operation of step b) of the process, the fibrous support coated with two fringed edges, which presented at the end of its training on the machine to paper of the areas of lesser thickness of fibers in the cross direction, undergoes a cutting operation to give leaves with fringed edge (s)) according to the invention.
Cette opération de découpe de l'étape c) du procédé selon l'invention se fait au moyen d'une coupeuse. Suivant le réglage de ladite coupeuse, ledit support issu de l'étape c) du procédé donnera une feuille à deux bords frangés ou une feuille à quatre bords frangés selon l'invention.This cutting operation of step c) of the method according to the invention is done by means of a cutter. According to the setting of said cutter, said support resulting from step c) of the process will give a sheet with two fringed edges or a sheet with four fringed edges according to the invention.
L'Homme du Métier est à même d'effectuer les réglages précis et nécessaires à l'obtention d'une feuille à deux bords frangés ou à quatre bords frangés selon l'invention.Those skilled in the art are able to make the precise and necessary adjustments to obtain a sheet with two fringed edges or four fringed edges according to the invention.
Une opération de découpe droite et nette réalisée au niveau desdites zones de moindre épaisseur présentes dans le sens travers de la feuille donnera des feuilles formatées à deux bords frangés couchées et imprimable par jet d'encre selon l'invention, tandis qu'une rupture de la feuille au niveau de ses zones de moindre épaisseur, par un réglage particulier de la vitesse de la coupeuse, sera à l'origine de feuilles formatées à quatre bords frangés, couchées et imprimable par jet d'encre conformément à l'invention.A straight and sharp cutting operation carried out at the level of said zones of lesser thickness present in the cross-machine direction of the sheet will give sheets formatted with two fringed edges lying down and printable by inkjet according to the invention, while a rupture of the sheet at its areas of lesser thickness, by a particular adjustment of the speed of the cutter, will cause formatted sheets with four edges fringed, coated and printable by ink jet according to the invention.
Selon un mode de réalisation du procédé de l'invention, l'étape b) de couchage et/ou l'étape c) de découpe peuvent être réalisées hors machine à papier.According to one embodiment of the method of the invention, the coating step b) and / or the cutting step c) can be performed off the paper machine.
Dans un mode de réalisation particulier du procédé selon l'invention, les étapes b) et c) sont réalisées hors machine à papier. L'opération de couchage -l'étape b)-est alors effectuée de préférence par une coucheuse à lame d'air ou une coucheuse à rideau.In a particular embodiment of the method according to the invention, steps b) and c) are performed outside the paper machine. The coating operation - step b) is then preferably carried out by an air knife coater or a curtain coater.
Selon un autre mode de mise en oeuvre du procédé de l'invention, les étapes a) et b) peuvent être réalisées en ligne, par exemple, au moyen d'un dispositif de couchage à rideau en ligne sur la machine à papier, tandis que l'étape c) de découpe est réalisée hors machine à papier.According to another embodiment of the method of the invention, steps a) and b) can be carried out online, for example by means of an inline curtain coating device on the paper machine, while that step c) of cutting is performed off paper machine.
Selon un cas particulier de mise en oeuvre du procédé selon l'invention, une feuille à bord(s) frangé(s), de préférence à deux bords frangés, plus préférentiellement à quatre bords frangés, couchée et imprimable par jet d'encre peut être avantageusement fabriquée entièrement en ligne sur machine à papier, sans effectuer d'opérations de couchage et de découpe hors machine qui augmentent les coûts de fabrication.According to a particular case of implementation of the method according to the invention, a sheet with fringed edge (s), preferably with two fringed edges, more preferably with four fringed edges, lying down and printable by inkjet can advantageously be manufactured entirely online on a paper machine, without performing operations of coating and cutting off machine that increase manufacturing costs.
Selon l'invention, la feuille à bord(s) frangé(s) couchée obtenue selon le procédé tel que décrit précédemment présente la caractéristique d'être imprimable par jet d'encre, et de présenter les qualités requises pour les impressions par jet d'encre, notamment en terme de rendu d'impression.According to the invention, the sheet with fringed edge (s) coated obtained by the method as described above has the characteristic of being printable by jet of ink, and to present the qualities required for inkjet printing, especially in terms of print rendering.
L'invention concerne enfin l'utilisation d'une feuille à bord(s) frangé(s) imprimable et couchée selon l'invention pour faire des impressions par jet d'encre.Finally, the invention relates to the use of a fringed sheet (s) printable and coated according to the invention to make inkjet printing.
