Description

PROCEDE D'IMPRESSION SUR CORPS TUBULAIRES D'UN DECOR PRESENTANT SIMULTANEMENT DES MOTIFS BRILLANTS ET DES MOTIFS MATS OU SATINES METHOD FOR PRINTING ON TUBULAR BODIES A DECORATION SHOWING SIMULTANEOUSLY BRILLIANT PATTERNS AND MATTE OR SATIN PATTERNS
DOMAINE TECHNIQUETECHNICAL AREA
L'invention concerne un procédé d' impression sur corps cylindriques permettant d 'obtenir un décor possédant simultanément des motifs brillants et des motifs mats ou satinés. L'invention concerne plus particulièrement un procédé d ' impression offset à sec.The invention relates to a method of printing on cylindrical bodies making it possible to obtain a decoration having simultaneously brilliant patterns and matt or satin patterns. The invention relates more particularly to a dry offset printing process.
ETAT DE LA TECHNIQUESTATE OF THE ART
L'impression offset à sec est utilisée couramment lorsqu'il s'agit d'imprimer la surface extérieure d'un objet cylindrique de révolution tel qu'une boîte-boisson, un boîtier de distributeur aérosol ou un tube souple. Ce procédé consiste à déposer plusieurs encres de couleurs différentes sur un blanchet puis à transférer ces encres par contact du blanchet avec la surface cylindrique à imprimer. En général, plusieurs blanchets sont montés sur un plateau tournant appelé table porte-blanchet. Les encres sont déposées successivement sur chaque blanchet au moyen de cylindres porte-cliché, appelés également clichés, qui sont des rouleaux d'application présentant des parties en relief formées par photogravure à partir d'un négatif. Il y a un cliché par couleur. Leur montage nécessite une mise au point minutieuse pour obtenir la juxtaposition souhaitée des couleurs, c'est-à-dire sans décalage d'un motif coloré par rapport au motif d'une autre couleur. Cette opération consistant à caler le positionnement des clichés est appelée calage des couleurs. Une fois réglée, la machine assure le positionnement précis et répétitif des couleurs les unes par rapport aux autres. Les encres sont ensuite séchées - par voie thermique ou par emploi de rayons ultra-violets - puis la surface est recouverte par un vernis qui protège le décor imprimé des agressions extérieures ou encore, notamment si la paroi est en matière plastique, à accentuer la barrière de diffusion aux gaz et aux arômes. L'aspect général mat ou brillant du décor est donné par le vernis. Le vernis est en général déposé par application au rouleau sur toute la surface du corps cylindrique avec un dispositif simple distinct de la machine offset. L'emploi d'un dispositif simple distinct de la machine offset est possible car le dépôt se fait sur toute la surface du corps cylindrique et qu'il n'y a pas besoin de placer le vernis par rapport à un repère associé au décor.Dry offset printing is commonly used when printing the exterior surface of a cylindrical object of revolution such as a beverage can, an aerosol dispenser can or a flexible tube. This process consists of depositing several inks of different colors on a blanket and then transferring these inks by contact of the blanket with the cylindrical surface to be printed. In general, several blankets are mounted on a turntable called a blanket table. The inks are deposited successively on each blanket by means of plate cylinders, also called plates, which are application rollers having parts in relief formed by photoengraving from a negative. There is one photo per color. Their assembly requires careful development to obtain the desired juxtaposition of colors, that is to say without shifting a colored pattern relative to the pattern of another color. This operation of calibrating the positioning of the pictures is called color calibration. Once adjusted, the machine ensures precise and repetitive positioning of the colors in relation to each other. The inks are then dried - thermally or by the use of ultraviolet rays - then the surface is covered with a varnish which protects the printed decoration from external aggressions or, especially if the wall is made of plastic, to accentuate the barrier. diffusion with gases and aromas. The general matt or shiny appearance of the decor is given by the varnish. The varnish is generally deposited by roller application over the entire surface of the cylindrical body with a simple device distinct from the offset machine. The use of a simple device distinct from the offset machine is possible because the deposit is made over the entire surface of the cylindrical body and there is no need to place the varnish relative to a mark associated with the decoration.
En effet, en cas de reprise, c'est-à-dire lorsqu'il faut utiliser un deuxième dispositif distinct du premier dispositif pour imprimer un motif supplémentaire , il faut pouvoir positionner ce motif supplémentaire par rapport à ceux déjà déposés. On utilise dans ce cas la technique du repérage : on imprime avec le premier dispositif un repère caractéristique du positionnement des premiers motifs du décor et on équipe le deuxième dispositif d'impression d'un dispositif de lecture optique qui, en repérant ce repère, permet au deuxième dispositif de placer correctement les motifs ultérieurs. Le repérage est une technique de juxtaposition ou de surimpression délicate à mettre au point et d'autant moins précise que la cadence de production est élevée. La difficulté est d'autre part nettement plus grande lorsqu'il s'agit d'imprimer la surface cylindrique de corps tubulaires.Indeed, in case of recovery, that is to say when it is necessary to use a second device separate from the first device to print an additional pattern, it must be able to position this additional pattern relative to those already deposited. In this case, the locating technique is used: a mark characteristic of the positioning of the first patterns of the decoration is printed with the first device and the second printing device is fitted with an optical reading device which, by locating this mark, allows the second device to correctly place the subsequent patterns. Marking is a technique of juxtaposition or overprinting which is difficult to develop and which is all the less precise when the production rate is high. The difficulty is, on the other hand, much greater when it comes to printing the cylindrical surface of tubular bodies.
Pour obtenir un effet de contraste mat/brillant, l'homme du métier peut envisager :To obtain a matt / glossy contrast effect, a person skilled in the art can consider:
• soit d'utiliser, après avoir fait sécher les encres, un deuxième dispositif offset pour déposer un vernis mat et un vernis brillant (dans ce cas on immobilise un deuxième dispositif coûteux et difficile à mettre au point) • soit d'appliquer un premier vernis au rouleau, le sécher puis déposer sélectivement un deuxième vernis par sérigraphie• or to use, after having dried the inks, a second offset device to deposit a matt varnish and a gloss varnish (in this case a second expensive device is immobilized and difficult to develop) • or apply a first varnish with a roller, dry it then selectively deposit a second varnish by screen printing
Quelle que soit la solution employée, l'homme du métier doit utiliser la technique du repérage qui diminue les cadences de production et nécessite des actions correctives fréquentes. Le problème du positionnement des deux vernis par rapport au décor encré (premier cas) ou du deuxième vernis par rapport au premier vernis (deuxième cas) est en effet délicat à résoudre car il ne s'agit plus de caler le positionnement de clichés sur une machine offset (mise au point faite une fois pour toutes) mais de reconnaître à l'aide d'un dispositif optique un repère imprimé sur la paroi cylindrique en même temps que les premiers motifs et de placer la zone à imprimer par rapport à ce repère.Whatever the solution used, those skilled in the art must use the tracking technique which reduces production rates and requires frequent corrective actions. The problem of positioning the two varnishes with respect to the inked decoration (first case) or the second varnish with respect to the first varnish (second case) is indeed difficult to solve because it is no longer a question of calibrating the positioning of photographs on a offset machine (focus made once and for all) but to recognize with an optical device a mark printed on the cylindrical wall at the same time as the first patterns and to place the area to be printed relative to this mark .
PROBLEME POSEPROBLEM
Pour conserver les cadences de production élevées de corps cylindriques tels que des tubes plastiques ou des boîtiers aérosols, la demanderesse a cherché un procédé évitant le repérage. Il s'agissait donc de trouver un procédé économique d'impression sur corps cylindriques permettant de donner un effet de contraste mat/brillant sur un décor vernis, ce procédé s' effectuant sans reprise c'est-à-dire ne mobilisant pas une machine offset supplémentaire ou une machine de sérigraphie supplémentaire et n'imposant pas des contraintes de repérage délicates sur le décor. OBJET DE L'INVENTIONTo keep the high production rates of cylindrical bodies such as plastic tubes or aerosol cans, the Applicant has sought a method avoiding the identification. It was therefore a question of finding an economical printing process on cylindrical bodies making it possible to give a matt / glossy contrast effect on a varnished decoration, this process being carried out without recovery, that is to say not using a machine. additional offset or an additional screen printing machine and does not impose delicate marking constraints on the decor. OBJECT OF THE INVENTION
L'objet de l'invention est un procédé d'impression sur corps cylindriques de décors vernis présentant simultanément des motifs brillants et des motifs mats ou satinés caractérisé en ce qu'on choisit, suivant le motif à imprimer, une encre mate ou une encre brillante en fonction de l'aspect final recherché en cette partie du décor, en ce qu'on imprime chacun desdits motifs avec ladite encre et en ce qu'on applique aussitôt un vernis brillant sur l'ensemble de la surface du corps tubulaire.The object of the invention is a method of printing on cylindrical bodies of varnished decorations having simultaneously brilliant patterns and matt or satin patterns characterized in that one chooses, according to the pattern to be printed, a matt ink or an ink glossy as a function of the final appearance sought in this part of the decoration, in that each of said patterns is printed with said ink and in that a glossy varnish is immediately applied to the entire surface of the tubular body.
Selon l'invention, les encres, choisies mates ou brillantes selon l'aspect final recherché, sont déposées - par exemple à l'aide d'une machine offset à sec - et le vernis brillant est déposé aussitôt après, c'est-à-dire sans attendre que les encres soient sèches.According to the invention, the inks, chosen matt or glossy depending on the desired final appearance, are deposited - for example using a dry offset machine - and the gloss varnish is deposited immediately after, that is to say - say without waiting for the inks to be dry.
Le vernis peut par exemple être appliqué au rouleau juste derrière la machine offset, comme illustré sur la figure.The varnish can for example be applied with a roller just behind the offset machine, as illustrated in the figure.
Lorsque les corps cylindriques ont des parois métalliques nues - par exemple des corps de boîtiers pour distributeurs aérosols - on recouvre de préférence la surface métallique nue avant impression, par application au rouleau d'une couche de primaire d'accrochage. Avec un corps de boîtier en aluminium, on utilise un primaire de type résine polyester modifié.When the cylindrical bodies have bare metal walls - for example casing bodies for aerosol dispensers - the bare metal surface is preferably covered before printing, by applying a layer of primer to the roller. With an aluminum housing body, a modified polyester resin type primer is used.
Des encres mates existent sur le marché mais il est préférable de réaliser celles- ci à partir de l'encre brillante de couleur correspondante et de les mater par ajout de charge minérale ou organique. Par exemple, on ajoute dans l'encre brillante 5% à 20% en poids de poudre de silice. Celle-ci doit avoir une granulométrie adaptée : les particules doivent être suffisamment fines pour pouvoir être entraînées par les matières volatiles qui se dégagent lors du séchαge mais suffisamment grosses pour qu'arrivées à la surface du vernis, elles perturbent le relief de ladite surface et en modifient les qualités réfléchissantes.Matt inks exist on the market, but it is preferable to make them from glossy ink of the corresponding color and to matt them by adding mineral or organic filler. For example, 5% to 20% by weight of silica powder is added to the glossy ink. This must have a suitable particle size: the particles must be sufficiently fine to be able to be entrained by the volatile materials which are released during the drying but large enough that when they reach the surface of the varnish, they disturb the relief of said surface and modify its reflective qualities.
Bien que l'observation de la couche vernie soit très difficile en raison de sa faible épaisseur, la demanderesse suppose en effet que le résultat surprenant consistant en ce que le vernis brillant devient mat en certains endroits est dû à la migration des particules matantes de l'encre mate vers la surface extérieure du vernis, migration sans doute facilitée par l'évacuation centrifuge des matières volatiles de l'encre et du vernis. La demanderesse a constaté qu'une poudre mélangée à l'encre avec un pourcentage pondéral de 10% et ayant un diamètre passant D50 compris entre 3 μ et 10 μ donnait de bons résultats, les meilleurs se situant aux alentours de 6μ.Although the observation of the varnished layer is very difficult due to its small thickness, the Applicant indeed assumes that the surprising result consisting in that the glossy varnish becomes matt in certain places is due to the migration of the matting particles from the matt ink towards the exterior surface of the varnish, migration probably facilitated by the centrifugal evacuation of volatile matter from the ink and varnish. The Applicant has found that a powder mixed with ink with a weight percentage of 10% and having a passing diameter D50 of between 3 μ and 10 μ gave good results, the best being around 6 μ.
Le séchage est effectué par voie thermique ou voie UV suivant la nature des encres et du vernis. Pour permettre aux particules matantes de migrer de l'encre vers le vernis, il est préférable de viser un séchage progressif. Ainsi, en ce qui concerne le séchage UV, on le décomposera de préférence en deux étapes:Drying is carried out thermally or UV depending on the nature of the inks and varnish. To allow the matting particles to migrate from the ink to the varnish, it is preferable to aim for gradual drying. Thus, with regard to UV drying, it will preferably be broken down into two stages:
• un premier passage de 2 à 6 minutes dans un four où règne une température comprise entre 60 et 100 °C• a first passage of 2 to 6 minutes in an oven where a temperature between 60 and 100 ° C prevails
• un deuxième passage correspondant au procédé de séchage UV classique.• a second pass corresponding to the conventional UV drying process.
En ce qui concerne le séchage thermique, on cherchera à ne pas atteindre trop rapidement la température habituellement utilisée, voisine de 180°C, en imposant par exemple un palier d'une à trois minutes aux environs de 100°C. MODE DE REALISATION DE L'INVENTIONRegarding thermal drying, we will try not to reach too quickly the temperature usually used, around 180 ° C, for example by imposing a level of one to three minutes around 100 ° C. EMBODIMENT OF THE INVENTION

Ce dispositif permet l'impression sans reprise en offset sec d'un décor de boîtier aérosol en aluminium avec un vernis de finition dont le rendu est simultanément mat et brillant à des endroits déterminés du décor.This device allows the printing without recovery in dry offset of an aluminum aerosol can decoration with a finishing varnish whose rendering is simultaneously matt and shiny at determined places of the decoration.
Le séchage des encres et du vernis se fait par voie thermique.The drying of inks and varnish is done thermally.
Le procédé de fabrication de tels boîtiers peut se décrire succinctement ainsi :The manufacturing process for such cases can be described succinctly as follows:
A. Avant impression :A. Before printing:
• filage par choc d'un pion en aluminium, • mise à longueur (affranchissage ou rognage) de la paroi cylindrique de l'ébauche filée,• impact spinning of an aluminum pin, • cutting to length (franking or trimming) of the cylindrical wall of the extruded blank,
• traitement de surface des surfaces de ladite ébauche, vernissage intérieur (le vernis intérieur est destiné à isoler du métal de la paroi le produit qui sera contenu dans le boîtier), • séchage du vernis.• surface treatment of the surfaces of said blank, interior varnishing (the interior varnish is intended to isolate from the metal of the wall the product which will be contained in the housing), • drying of the varnish.
B. ImpressionB. Printing
• Application d'un primaire d'accrochage sur le substrat en aluminium. On utilise ici une résine polyester modifié référencé SP-72KM309/2 par la société BLANCOME.• Application of a bonding primer on the aluminum substrate. A modified polyester resin referenced SP-72KM309 / 2 by the company BLANCOME is used here.
• Préparation des encres :• Preparation of inks:
* Pour les encres brillantes :* For glossy inks:
On utilise des encres brillantes à séchage thermique référencées dans la série Galathe (marque déposée) de la société VALSPAR. Ces encres, correspondant aux différents motifs colorés du décor, sont utilisées sans aucun ajout supplémentaire. * Pour les encres mates:Glossy thermal drying inks referenced in the Galathe series (registered trademark) from the company VALSPAR are used. These inks, corresponding to the different colored patterns of the decor, are used without any additional addition. * For matt inks:
Pour les parties devant avoir un aspect mat, on mélange l'encre correspondante avec 10% de silice. Les particules de silice utilisées ont un diamètre moyen de 3 μ et un passant à 50% de 6 μ.For the parts which must have a mat appearance, the corresponding ink is mixed with 10% silica. The silica particles used have an average diameter of 3 μ and a 50% passer of 6 μ.
• Application des encres mates et brillantes à l'aide d'un dispositif mettant en oeuvre le procédé offset sec.• Application of matt and shiny inks using a device implementing the dry offset process.
• Application d'un vernis polyester sur les encres sans aucun séchage intermédiaire : il se passe 1 /2 seconde environ entre la fin du dépôt de la dernière encre et le début du dépôt du vernis. Ce dépôt de vernis est appelé ici survernissage pour le distinguer du dépôt du vernis interne (voir A).• Application of a polyester varnish on the inks without any intermediate drying: it takes about 1/2 second between the end of the deposit of the last ink and the start of the deposit of the varnish. This deposit of varnish is called here over-varnishing to distinguish it from the deposit of the internal varnish (see A).
• Passage dans un four à 180° pendant 6 minutes avec une ventilation soutenue, c'est-à-dire générant un courant d'air circulant à plus de # 3 m/s au voisinage de la surface extérieure des ébauches cylindriques des boîtiers.• Passage in an oven at 180 ° for 6 minutes with sustained ventilation, that is to say generating a current of air circulating at more than # 3 m / s in the vicinity of the external surface of the cylindrical blanks of the housings.
