Abstract

The method involves overprinting the print image with a glass body lacquer (6). A layer of glass body lacquer is overprinted with a transparent protective lacquer. The desired resistance of glass body lacquers has increased size of the glass body and strong layer thickness of the glass body lacquer.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Oberflächen im Siebdruckverfahren entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a method for the production of surfaces by screen printing according to the preamble of claim 1.

Beschreibung der derzeitigen Situation:

  • Vor allem Drucke, die auf/fiir technische/industrielle Produkte eingesetzt werden, z.B. Verklebungen für Getränkeschränke und Kühltruhen, haben erhöhte Anforderungen an die Oberflächenbeschaffenheit. Durch den Einsatz an öffentlichen Orten bzw. unter erschwerten Umgebungsbedingungen, wird die Oberfläche dieser Produkte häufig zerkratzt und entspricht damit nicht mehr den Qualitätsvorstellungen der Erzeuger und der Anwender bzw. werden Bildmotive unansehnlich.
Description of the current situation:
  • In particular, prints used on technical / industrial products, eg adhesives for beverage cabinets and freezers, have higher surface quality requirements. When used in public places or under difficult environmental conditions, the surface of these products is often scratched and thus no longer meets the quality expectations of the producers and the user, or they become unsightly.

Um eine robuste Oberfläche herzustellen, werden bisher zwei Verfahren angewendet:

  1. 1. Der Druck wird auf der bedruckten Seite mit einer durchsichtigen Folie zusätzlich laminiert.
  2. 2. Das Druckbild wird auf die Rückseite einer durchsichtigen Folie aufgebracht, danach wird das Druckbild weiß überdruckt, auf den Weißdruck wird eine Doppelklebefolie aufgebracht (siehe Fig. 1).
In order to produce a robust surface, two methods are currently used:
  1. 1. The print is additionally laminated on the printed side with a transparent film.
  2. 2. The printed image is applied to the back of a transparent film, then the print image is overprinted white, on the white print a double-adhesive film is applied (see Fig. 1 ).

Beim ersten Verfahren handelt es sich um ein übliches Verfahren zum Schutz der Oberfläche. Der Nachteil ist, dass damit nur eine geringe Härte der Oberfläche erzielbar ist, die nicht den oben genannten Ansprüchen gerecht wird. Weiters ergibt sich durch das Laminieren ein zusätzlicher Arbeitsgang.The first method is a common method of protecting the surface. The disadvantage is that thus only a low hardness of the surface can be achieved, which does not meet the above requirements. Furthermore, lamination results in an additional operation.

Auch beim zweiten Verfahren handelt es sich um sehr aufwendiges Verfahren und es ist die gewünschte Härte der Oberfläche nicht erzielbar, weil die durchsichtigen Kunststofffolien, z.B. aus PVC, Polypropylen, Polystyrol nicht die entsprechenden physikalischen Eigenschaften aufweisen. Weitere Nachteile dieses Verfahrens sind eine geringe Beständigkeit gegenüber Löse- und Scheuermitteln, mangelnde Elastizität des Gesamtproduktes, aufwendigere Produktion durch Einsatz von zweikomponentigen Farben, Trocknungszeiten und Aufbringen der doppelseitigen Klebefolie, eine häufige gegenseitige Beeinflussung zwischen Klebefolie und den gedruckten Farben durch Restanteile an Lösungsmitteln, das Auftreten von Alterungserscheinungen wie Vergilben.Also in the second method is a very complicated process and it is the desired hardness of the surface can not be achieved because the transparent plastic films, such as PVC, polypropylene, polystyrene do not have the corresponding physical properties. Other disadvantages of this method are low resistance to solvents and abrasives, lack of elasticity of the overall product, more complex production through the use of two-component paints, drying times and application of the double-sided adhesive film, a frequent mutual influence between adhesive film and the printed colors due to residual proportions of solvents, the occurrence of aging phenomena such as yellowing.

Es besteht somit ein Bedarf an einem Verfahren, das auf möglichst einfache Weise, unter Verwendung von möglichst erprobten Materialien die gewünschte harte, abriebfeste, lösungs- und scheuermittelresistente Oberfläche in Verbindung mit einer ansprechenden Optik ergibt, ohne dass Einschränkungen beim Drucksubstrat etc. auftreten.Thus, there is a need for a process which provides the desired hard, abrasion-resistant, solvent-resistant and abrasion-resistant surface in the simplest possible way, using the best possible materials, in conjunction with an attractive appearance, without any restrictions on the printing substrate, etc.

Erreicht werden diese Ziele gemäß der Erfindung in Übereinstimmung mit dem kennzeichnenden Teil des Anspruches 1 durch das Aufbringen einer speziellen Kombination von ein bis drei, gegebenenfalls auch mehr Schichten von Schutzlack(en) auf das Substrat/Bedruckstoff. Es wird so eine mechanisch robuste Oberfläche für Druckerzeugnisse erreicht, ohne die Farbintensität des Druckbildes zu beeinträchtigen. Als Substrat ist jegliches Material geeignet, welches im Siebdruckverfahren bedruckt werden kann.These objects are achieved according to the invention in accordance with the characterizing part of claim 1 by applying a special combination of one to three, optionally also more layers of protective lacquer (s) on the substrate / substrate. It is thus achieved a mechanically robust surface for printed products, without affecting the color intensity of the printed image. As substrate, any material is suitable which can be screen printed.

Die Erfindung wird im Folgenden unter Bezugnahme auf die Zeichnung näher erläutert. Dabei zeigt

  • die Fig. 1 einen Schichtenaufbau gemäß dem Stand der Technik,
  • die Fig. 2 einen ersten, erfindungsgemäßen Schichtenaufbau,
  • die Fig. 3 ein Detail im vergrößerten Maßstab,
  • die Fig. 4 in zwei Ansichten zwei verschiedene Möglichkeiten der ersten Schutzlackschicht und
  • die Fig. 5 in zwei Ansichten zwei verschiedene Möglichkeiten der Ausbildung der zweiten Schutzlackschicht.
The invention will be explained in more detail below with reference to the drawing. It shows
  • the Fig. 1 a layer structure according to the prior art,
  • the Fig. 2 a first layer structure according to the invention,
  • the Fig. 3 a detail on an enlarged scale,
  • the Fig. 4 in two views, two different possibilities of the first protective lacquer layer and
  • the Fig. 5 in two views, two different ways of forming the second resist layer.

Fig. 1 zeigt einen mehrschichtigen Aufbau entsprechend dem Stand der Technik: Eine durchsichtige Folie 1 ist an ihrer dem Betrachter abgewandten Seite mit dem Druckbild (Motiv) 2 versehen, auf das ein Weißdruck 3 aufgedruckt ist. Mittels einer doppelseitig klebenden Folie 4 wird die bedruckte Folie auf das - nicht dargestellte - Substrat aufgebracht. Die Resistenz gegen Beschädigungen mechanischer oder chemischer Natur hängt ausschließlich an der Folie 1 und ist naturgemäß gering. Fig. 1 shows a multilayer structure according to the prior art: A transparent film 1 is provided on its side facing away from the viewer with the printed image (motif) 2, on which a white print 3 is printed. By means of a double-sided adhesive film 4, the printed film is applied to the - not shown - substrate. The resistance to damage of a mechanical or chemical nature depends exclusively on the film 1 and is naturally low.

Nach dem Druck des Sujets/Druckbildes (in wenigen Fällen auch ohne derartiges "Motiv") auf das Substrat wird eine erste Schutzschicht mit einem Glaskörperlack gedruckt, wie aus Fig. 2 ersichtlich ist. Glaskörperlack ist auch unter der Bezeichnung "Trittschutzlack" in zumindest drei Abstufungen der Partikelgröße, beispielsweise unter der Bezeichnung MLS 70/00, MLS 70/02 bzw. MLS 70/03 der Coates Screen Inks GmbH in Nürnberg, Bundesrepublik Deutschland, bekannt. Diese Lacke weisen Glaskörper in einer durchsichtigen (oder auch, hier aber nicht interessierenden, färbigen) Matrix auf, die wie ein üblicher Lack aushärtet.After printing the subject / print image (in a few cases even without such a "motif") on the substrate, a first protective layer is printed with a vitreous body lacquer, as in Fig. 2 is apparent. Vitreous body lacquer is also known under the name "impact protection lacquer" in at least three gradations of particle size, for example under the name MLS 70/00, MLS 70/02 or MLS 70/03 of Coates Screen Inks GmbH in Nuremberg, Federal Republic of Germany. These lacquers have glass bodies in a transparent (or even, but not interesting, colored) matrix which cures like a conventional lacquer.

Die Fig. 2 zeigt einen typischen, erfindungsgemäßen Aufbau: Direkt auf das Substrat 5 wird der Druck 2 (Motiv) aufgedruckt, bevorzugt als Siebdruck. Darauf wird mittels Siebdrucks eine Schicht Glaskörperlack 6 und gegebenenfalls eine Abdeckschicht aufgedruckt und so eine äußerst resistente Oberfläche 7 geschaffen. Der Maßstab der Fig. 2 lässt eine detaillierte Betrachtung des Ausbaus der Schichte 6 nicht zu, dieser wird anhand der folgenden Figuren erläutert.The Fig. 2 shows a typical structure according to the invention: directly on the substrate 5, the print 2 (motif) is printed, preferably as a screen printing. Then, by means of screen printing, a layer of vitreous paint 6 and optionally a covering layer are printed on, thus creating an extremely resistant surface 7. The scale of Fig. 2 does not allow a detailed consideration of the expansion of the layer 6, this will be explained with reference to the following figures.

Dadurch wird die Oberfläche gut geschützt, weil der Glaskörperlack eine sehr harte Oberfläche aufweist. Je größer die Glaskörper bzw. je dicker ihre Schicht, ums stärker erhöht sich die Resistenz. Aufgrund der aus Fig. 3 und 4 ersichtlichen Struktur des Glaskörperlacks (in Fig. 3 ohne darunter liegende Schichten dargestellt), die eine raue Oberfläche 7 zur Folge hat, wird die Farbintensität verringert, das Druckbild erscheint stumpf und matt, die Oberfläche weist jedoch die gewünschte hervorragende mechanische Beständigkeit, und Beständigkeit gegenüber Löse- und Scheuermittel auf, kann durch die raue Oberfläche aber auch leicht Verschmutzen.As a result, the surface is well protected because the vitreous body paint has a very hard surface. The larger the vitreous or the thicker the layer, the more the resistance increases. Because of the 3 and 4 apparent structure of vitreous lacquer (in Fig. 3 without underlying layers), resulting in a rough surface 7, the color intensity is reduced, the print image appears dull and dull, but the surface has the desired excellent mechanical resistance, and resistance to solvents and scouring agents rough surface but also slightly dirty.

Um dem abzuhelfen, wird, wie die Fig. 5 zeigt, erfindungsgemäß bevorzugt nach dem Aufbringen des Glaskörperlacks 6 eine weitere Schicht 7 mit einem handelsüblichen durchsichtigen Lack gedruckt, bevorzugt ebenfalls mittels Siebdruck. Hierdurch werden die Vertiefungen des Glaskörperlacks im gewünschten Maß ausgefüllt. Durch das Ausfüllen der Vertiefungen verringert sich die Rauhigkeit der Oberfläche, damit die Tendenz zur Verschmutzung, und gleichzeitig nehmen die Farbintensität sowie die Transparenz und der Glanzgrad des Druckbildes zu, ohne dass die Härte und Widerstandskraft der Oberfläche merklich abnimmt. In Summe ergibt sich daher aus dieser Kombination eine harte Oberfläche und ein farbintensives Druckbild von seiden- bis hochglänzend, je nachdem, wie viel transparenter Lack aufgebracht bzw in welchem Ausmaß die Vertiefungen zwischen den Glaskörper gefüllt bzw die Glaskörper mit Lack überzogen werden. In den beiden Beispielen ist die obere Variante mit wenig Abdecklack 7 noch relativ matt, die untere weist eine Brillianz auf, die von üblichen Druckbildern nicht abweicht.To remedy this, like the Fig. 5 shows, according to the invention preferably after the application of the glass body paint 6 printed another layer 7 with a commercially available transparent lacquer, preferably also by screen printing. As a result, the wells of the vitreous body paint are filled to the desired extent. By filling in the depressions, the roughness of the surface decreases, so that the tendency to fouling, and at the same time increase the color intensity and the transparency and gloss level of the printed image, without the hardness and resistance of the surface decreases significantly. In sum, therefore, results from this combination a hard surface and a color-intensive printed image of silk to high gloss, depending on how much transparent paint applied or to what extent the wells are filled between the glass body or the glass body coated with paint. In the two examples, the upper variant with little Abdecklack 7 is still relatively matte, the lower has a brilliance, which does not deviate from conventional print images.

In Fig. 4 und 5 ist der Motivdruck nicht dargestellt.In 4 and 5 the motif print is not shown.

Die mechanische Beständigkeit und Beständigkeit gegenüber Löse- und Scheuermittel sowie die Farbintensität und die Rauhigkeit bzw der Glanzgrad der Oberfläche können durch die Auswahl des Glaskörperlacks sowie Geometrie und Kombination der benutzten Siebgewebe beim Aufbringen der Schutzlacke gesteuert werden. Der Druck des Glaskörperlackes erfolgt durch ein Gewebe. Durch die Fadenstärke und die Maschenweite des Druckgewebes im Verhältnis zum Durchmesser der Glaskugeln des Glaskörperlackes kann sowohl die Schichtstärke des Glaskörperlackes als auch die Rauheit der Oberfläche verändert bzw gesteuert werden.The mechanical resistance and resistance to solvents and abrasives as well as the color intensity and the roughness or the gloss level of the surface can be controlled by the choice of vitreous paint and the geometry and combination of the screen meshes used in the application of the protective coatings. The pressure of the vitreous body lacquer is effected by a tissue. Due to the thread thickness and the mesh size of the printing fabric in relation to the diameter of the glass beads of the vitreous body lacquer both the layer thickness of the glass body lacquer and the roughness of the surface can be changed or controlled.

Eine Erhöhung der Schichtstärke und/oder die Verwendung eines Glaskörperlacks mit größeren Glaskörpern hat eine Erhöhung der mechanische Beständigkeit und Beständigkeit gegenüber Löse- und Scheuermittel zur Folge, wie in Fig. 4 angedeutet. Durch den Grad der Füllung der Vertiefungen mit dem handelsüblichen durchsichtigen Lack, angedeutet durch die beiden unterschiedlichen Füllungsgrade in Fig. 5, entsprechend unterschiedlichen Schichtdicken der Aufbringung, kann die Farbintensität gesteuert werden.An increase in the layer thickness and / or the use of a glass body paint with larger glass bodies results in an increase in the mechanical resistance and resistance to solvents and abrasives, as in Fig. 4 indicated. By the degree of filling of the wells with the commercially available transparent lacquer, indicated by the two different degrees of filling in Fig. 5 , according to different layer thicknesses of the application, the color intensity can be controlled.

Weitere Vorteile gegenüber den bisherigen Verfahren sind die leichte Herstellbarkeit in einem Produktionsablauf auf einer Mehrfarben-Siebdruckmaschine und die Möglichkeit, jegliches Substrat bzw jegliche Bedruckstoffe verwenden zu können. Dabei ist es unerheblich, ob das zu schützende Motiv im Sieb-, Offset- oder Digitaldruck hergestellt wurde. Alterungserscheinungen können durch die Auswahl der entsprechenden Substrate/Bedruckstoffe (Trägerfolie) und natürlich der Farben auf ein vernachlässigbares Maß reduziert werden.Further advantages over the previous methods are the ease of manufacture in a production process on a multi-color screen printing machine and the ability to use any substrate or any substrates can. It is irrelevant whether the motif to be protected was produced by screen, offset or digital printing. Aging phenomena can be reduced to a negligible level by selecting the appropriate substrates / substrates (backing film) and, of course, the colors.

Erwähnt soll noch werden, dass es beim überlappenden Verkleben von derart bedruckten Folien notwendig ist, über den Glaskörperdruck noch zumindest eine Schichte eines handelsüblichen (natürlich transparenten) Lacks zu drucken, da ansonsten die Überlappung nicht dauerhaft verklebt werden kann, da der Klebstoff auf dem Glaskörperlack nicht ausreichend haftet. Ein solches überlappendes Verkleben ist bei größeren Formaten notwendig.Mention should also be made that it is necessary in the overlapping gluing of such printed films to print on the glass body printing at least a layer of a commercially available (of course transparent) paint, otherwise the overlap can not be permanently bonded, as the adhesive on the glass body paint not sufficiently liable. Such an overlapping gluing is necessary for larger formats.

Als Substrat eignen sich sämtliche Substrate, die im Stand der Technik für Siebdruck geeignet sind, insbesondere Kunststofffolien. Die zu schützenden Oberflächen können, müssen aber nicht selbst durch Siebdruckverfahren hergestellt worden sein, der Glaskörperlack und bevorzugt auch die zumindest eine Schichte aus transparentem Lack zur Erhöhung der Farbtiefe und Brillianz werden mittels Siebdruck aufgebracht. In Kenntnis der Erfindung ist die Verwendung des im Stand er Technik als Trittschutzlack bekannten Lacks für die erfindungsgemäßen Zwecke für den Fachmann der Siebdrucktechnik ohne Probleme möglich.Suitable substrates are all substrates which are suitable for screen printing in the prior art, in particular plastic films. The surfaces to be protected can, but need not have been produced by screen printing, the glass body paint and preferably also the at least one layer of transparent lacquer to increase the color depth and brilliance are applied by screen printing. In the knowledge of the invention, the use of known in the art he prior art as a protective lacquer for the purposes of the invention for those skilled in the screen printing technology without any problems.

Der Glaskörperlack muss nicht die gesamte Oberfläche des Substrats bedecken sondern kann, je nach Bedarf, entweder das zu schützende Motiv und/oder die besonderen Anfechtungen ausgesetzte Bereiche betreffen.The vitreous body paint does not have to cover the entire surface of the substrate, but may, as needed, affect either the subject to be protected and / or the areas subject to particular challenges.
