Description
FLAN DE VERNISSAGE DESTINE A APPOSER UN VERNIS SUR UNEFLAN OF VERNISSAGE INTENDED TO APPLY A VARNISH ON A
FEUILLE IMPRIMEE.PRINTED SHEET.
Domaine technique de l'invention.Technical Field of the Invention
L'invention est du domaine de l'imprimerie, et plus particulièrement des dispositifs pour traiter la surface des feuilles imprimées, ou supports imprimés analogues, par vernissage notamment. Elle a pour objet un flan de vernissage destiné à apposer un vernis ou analogue sur un support imprimé. The invention is in the field of printing, and more particularly devices for treating the surface of printed sheets, or similar printed media, in particular by varnishing. It relates to a varnishing blank for affixing a varnish or the like on a printed medium.
Etat de la technique.State of the art
On rappelle que dans le domaine de l'imprimerie, il est courant de placer un poste de vernissage en sortie d'un groupe d'imprimerie d'un support à imprimer. Ce poste de vernissage est destiné à apposer un vernis sur la face imprimée du support, en vue de sa protection notamment. Ce poste de vernissage est principalement constitué d'un cylindre rotatif revêtu à sa périphérie d'un flan de vernissage, qui est enduit de vernis pour ensuite l'apposer par contact sur le support. It is recalled that in the field of printing, it is common to place a varnishing station at the output of a printing group of a print medium. This varnishing station is intended to affix a varnish on the printed side of the support, in particular for its protection. This varnishing station consists mainly of a rotary cylinder coated at its periphery with a varnishing blank, which is coated with varnish and then affixed by contact on the support.
On notera à ce stade de la description que le vernis peut être apposé sur la quasi totalité de la face imprimée du support suivant une surface continue, ou en ménageant des zones exemptes de vernis. Ces zones sont notamment destinées à recevoir ultérieurement de la colle, en vue d'un maintien en conformation du support replié sur lui-même. It will be noted at this stage of the description that the varnish can be applied to almost the entire printed surface of the support along a continuous surface, or by providing areas free of varnish. These areas are particularly intended to receive later glue, for a maintenance in conformation of the folded support on itself.
De manière habituelle, le flan de vernissage est constitué d'un blanchet, du genre de ceux couramment utilisés pour l'apposition d'encre sur le support à imprimer. On rappelle que de tels blanchets sont constitués d'un flan souple stratifié, associant une toile sur laquelle est vulcanisée au moins une couche de caoutchouc pour le transfert du vernis sur le support imprimé. In the usual way, the varnishing blank consists of a blanket, of the type commonly used for applying ink to the printing medium. It is recalled that such blankets consist of a flexible laminated blank, combining a fabric on which is vulcanized at least one layer of rubber for the transfer of the varnish on the printed medium.
2869832 2 Pour délimiter la surface du blanchet devant être enduite de vernis, il est commun d'interposer une cale entre le blanchet et le cylindre rotatif, d'une dimension correspondante à la surface du blanchet à vernir. Ces dispositions visent à déformer le blanchet dans son plan général en ménageant une surépaisseur susceptible d'être seule enduite de vernis. Le cas échéant, des découpes sont localement pratiquées dans le blanchet pour former des réserves, en vue de ménager sur le support imprimé lesdites zones exemptes de vernis. In order to delimit the surface of the blanket to be coated with varnish, it is common to interpose a wedge between the blanket and the rotary cylinder, of a size corresponding to the surface of the blanket to be varnished. These provisions are intended to deform the blanket in its general plan by providing an extra thickness that can be coated alone varnish. Where appropriate, blanks are locally made in the blanket to form reserves, in order to spare on the printed support said areas free of varnish.
Si une telle pratique a donné jusqu'alors de bons résultats, il apparaît à l'usage que les exigences de qualité du transfert du vernis depuis le flan de vernissage sur le support doivent être améliorées. De telles améliorations sont notamment rendues dépendantes de l'utilisation de vernis nouvellement exploités, tels que des vernis acryliques, des vernis réactifs aux rayons ultraviolets, des vernis holographiques et/ou des vernis à l'aspect satiné par exemple. En outre, la formation des réserves susvisées dans le blanchet est délicate, en raison notamment de la vulcanisation du caoutchouc sur la toile, qui rend difficile la pratique de découpes, à bords nets notamment. En outre encore, l'utilisation d'un blanchet en tant que flan de vernissage, nécessite des opérations longues et fastidieuses d'installation du blanchet sur le cylindre rotatif, qui méritent d'être améliorées. Par ailleurs, les habitudes dans le domaine tendent à négliger l'aspect consommable du blanchet, à usage unique, avec en corollaire une incidence sur le coût de revient de l'impression du support et la nécessité du traitement du blanchet en tant que déchet. Toujours au regard de la consommation abusive de produits, l'utilisation d'un blanchet en tant que flan de vernissage tend à induire une consommation excessive de vernis. If such a practice has so far given good results, it appears in use that the quality requirements of the transfer of the varnish from the varnishing blank on the support must be improved. Such improvements are notably made dependent on the use of newly-used varnishes, such as acrylic varnishes, UV-reactive varnishes, holographic varnishes and / or varnishes with a satin appearance, for example. In addition, the formation of the abovementioned reserves in the blanket is difficult, particularly because of the vulcanization of the rubber on the fabric, which makes it difficult to cut, particularly sharp edges. In addition, the use of a blanket as a varnishing blank requires long and tedious operations of installation of the blanket on the rotary cylinder, which deserve to be improved. Moreover, the habits in the field tend to neglect the consumable aspect of the blanket, single-use, with consequent impact on the cost of printing the support and the need to treat the blanket as waste. Again with regard to the excessive consumption of products, the use of a blanket as a varnishing blank tends to induce an excessive consumption of varnish.
Objet de l'invention.Object of the invention
Le but de la présente invention est de proposer une alternative à l'utilisation d'un 30 blanchet comme flan de vernissage, en proposant un tel flan qui ne présente pas, sinon au moins de manière amoindrie, les inconvénients susvisés. . Le flan de la présente invention est un flan de vernissage destiné à apposer un vernis ou analogue sur un support imprimé. On notera à ce stade de la description, que le support imprimé est susceptible d'être à base d'un matériau cellulaire, tel que papier ou carton, ou encore à base de matière plastique, telle que polyester ou PVC. Un tel flan est prévu pour être rapporté à la périphérie d'un cylindre rotatif, et est du genre de flan stratifié comprenant une couche de base porteuse d'au moins une couche élastomère de transfert d'un vernis sur le support imprimé. The object of the present invention is to propose an alternative to the use of a blanket as a varnishing blank, by proposing such a blank which does not have, if not at least in a reduced way, the aforementioned drawbacks. . The blank of the present invention is a varnishing blank for affixing a varnish or the like on a printed support. It will be noted at this stage of the description that the printed medium is likely to be based on a cellular material, such as paper or cardboard, or based on a plastic material, such as polyester or PVC. Such a blank is intended to be attached to the periphery of a rotating cylinder, and is of the kind of laminated blank comprising a base layer carrying at least one elastomeric layer for transferring a varnish to the printed support.
Selon la présente invention, un tel flan est reconnaissable dans sa généralité en ce 10 qu'il est principalement constitué de ladite couche de base, enduite d'une couche de polyuréthane formant ladite couche élastomère de transfert. According to the present invention, such a blank is recognizable in its generality in that it consists mainly of said base layer, coated with a polyurethane layer forming said elastomeric transfer layer.
Il est apparu qu'un tel flan de vernissage, obtenu à faible coût et réutilisable sans perte de fiabilité, offrait une qualité excellente de transfert du vernis sur le support imprimé. Cette qualité de transfert permet en outre de limiter la consommation de vernis, et de simplifier les réglages nécessaires du poste de vernissage. En outre, un tel flan offre une faculté de transfert de qualité relativement constante quelle que soit la nature du support imprimé et du vernis utilisé. It appeared that such a varnishing blank, obtained at low cost and reusable without loss of reliability, offered an excellent quality of transfer of the varnish on the printed medium. This quality of transfer also makes it possible to limit the consumption of varnish, and to simplify the necessary adjustments of the varnishing station. In addition, such a blank offers a transfer faculty of relatively constant quality whatever the nature of the printed medium and the varnish used.
Par ailleurs, la pratique éventuelle de découpes pour la formation de réserves dans la couche de transfert en est facilitée, de telles découpes offrant de surcroît une bordure n'altérant pas la qualité du transfert du vernis sur les zones correspondantes du support à imprimer. Furthermore, the possible practice of cutting for the formation of reserves in the transfer layer is facilitated, such cuts also providing a border that does not affect the quality of the transfer of the varnish on the corresponding areas of the medium to be printed.
En outre, il est avantageusement apparu qu'une épaisseur de l'ordre de 0, 90 mm de la couche de transfert en polyuréthane donnait des résultats satisfaisants, et que la couche de base était susceptible de présenter une faible épaisseur sans porter atteinte ni à la cohésion de la couche de transfert, ni à la souplesse souhaité du flan. A titre indicatif, cette couche de base est susceptible d'être de l'ordre de 0,25 mm, conférant une épaisseur globale du flan de l'ordre de 1,15 mm, soit plus faible que l'épaisseur d'un blanchet courant du domaine, habituellement utilisé au poste de vernissage. In addition, it was advantageously found that a thickness of about 0.90 mm of the polyurethane transfer layer gave satisfactory results, and that the base layer was likely to have a small thickness without adversely affecting either the cohesion of the transfer layer, nor the desired flexibility of the blank. As an indication, this base layer is likely to be of the order of 0.25 mm, giving an overall thickness of the blank of the order of 1.15 mm, which is lower than the thickness of a blanket current of the domain, usually used at the varnishing station.
2869832 4 Selon une première variante de réalisation, la couche de base est un polyester. On notera qu'un tel flan offre des facultés particulièrement satisfaisantes pour la pratique aisée des découpes. Une application privilégiée d'un tel flan réside dans un vernissage sélectif du support en des zones prédéterminées par les découpes qui y sont pratiquées. According to a first variant embodiment, the base layer is a polyester. It will be noted that such a blank offers particularly satisfactory faculties for the easy practice of cutting. A preferred application of such a blank lies in a selective varnishing of the support in predetermined areas by the cuts that are made there.
Selon une deuxième variante de réalisation, la couche de base est une toile. Un tel flan offre une élasticité facilitant son installation sur un cylindre rotatif. En outre, un tel flan offre l'avantage d'être entièrement recyclable en déchet ordinaire. On notera aussi qu'un tel flan est plutôt, mais de manière non restrictive, destiné au vernissage d'une surface continue. Outre l'application susvisée de vernissage sélectif, un tel flan est plutôt destiné en un vernissage en aplat total du support, notamment en remplacement du blanchet traditionnellement utilisé en atelier. According to a second variant embodiment, the base layer is a fabric. Such a blank provides elasticity facilitating its installation on a rotary cylinder. In addition, such a blank has the advantage of being fully recyclable as ordinary waste. Note also that such a blank is rather, but not limited to, for varnishing a continuous surface. In addition to the aforementioned application of selective varnishing, such a blank is rather intended as a full flat coating of the support, particularly in replacement of the blanket traditionally used in the workshop.
La toile formant la couche de base est de préférence une toile tissée chaîne et trame, à partir de fils indifféremment monobrins ou multibrins. The fabric forming the base layer is preferably a woven fabric warp and weft, from son indifferently monobrins or strands.
On notera que la couche de base est susceptible d'être une toile en coton, ou 20 encore d'être une toile en fibres synthétiques. It will be appreciated that the base layer is likely to be a cotton fabric, or to be a synthetic fiber fabric.
