Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum verbesserten Direktdruck von Dekorpaneelen, sowie ein Verfahren zum verbesserten Direktdruck von Dekorpaneelen.The present invention relates to a device for improved direct printing of decorative panels, as well as a method for improved direct printing of decorative panels.

Eine Paneelbedruckungsvorrichtung nach dem Oberbegriff des Anspruchs 1 ist aus dem Dokument US 6 634 729 B1 bekannt.A panel printing apparatus according to the preamble of claim 1 is known from the document US 6 634 729 B1 known.

Unter dem Begriff Dekorpaneel sind im Sinne der Erfindung Wand-, Decken, oder Bodenpannele zu verstehen, welche ein auf eine Trägerplatte aufgebrachtes Dekor aufweisen. Dekorpaneele werden dabei in vielfältiger Weise sowohl im Bereich des Innenausbaus von Räumen, als auch zur dekorativen Verkleidung von Bauten, beispielsweise im Messebau verwendet. Eine der häufigsten Einsatzbereiche von Dekorpaneelen ist deren Nutzung als Fußbodenbelag. Die Dekorpaneele weisen dabei vielfach ein Dekor auf, welches einen Naturwerkstoff nachempfinden soll.For the purposes of the invention, the term decorative panel is understood to mean wall, ceiling or floor panels which have a decor applied to a carrier plate. Decorative panels are used in a variety of ways, both in the field of interior design of rooms, as well as the decorative cladding of buildings, for example in exhibition construction. One of the most common uses of decorative panels is their use as floor coverings. The decorative panels often have a decor that is intended to recreate a natural material.

Beispiele für solche nachempfundenen Naturwerkstoffe sind Holzart wie z.B. Ahorn, Eiche, Birke, Kirsche, Esche, Nussbaum, Kastanie, Wenge oder auch exotische Hölzer wie Panga-Panga, Mahagoni, Bambus und Bubinga. Darüber hinaus werden vielfach Naturwerkstoffe wie Steinoberflächen oder Keramikoberflächen nachempfunden.Examples of such simulated natural materials are wood species such as e.g. Maple, oak, birch, cherry, ash, walnut, chestnut, wenge or even exotic woods such as panga panga, mahogany, bamboo and bubinga. In addition, many natural materials such as stone surfaces or ceramic surfaces are modeled.

Bisher werden solche Dekorpaneele vielfach als Laminate hergestellt, bei welchen auf eine Trägerplatte ein mit einem gewünschten Dekor vorbedrucktes Dekorpapier aufgebracht wird, auf welches dann wiederum ein sogenanntes Overlay aufgebracht wird. Nachdem gegebenenfalls noch auf der dem Dekorpapier gegenüberliegenden Seite der Trägerplatte ein Gegenzugpapier aufgebracht wurde, wird der erhaltene Schichtenaufbau unter Verwendung geeigneter druck- und/oder wärmeaktivierter Klebemittel fest miteinander verbunden.So far, such decorative panels are often produced as laminates, in which on a carrier plate with a desired decor pre-printed decorative paper is applied, which in turn is then applied a so-called overlay. After optionally a Gegenzugpapier was still applied to the decorative paper opposite side of the support plate, the layer structure obtained is firmly bonded together using suitable pressure and / or heat-activated adhesive.

In Anhängigkeit des gewünschten Einsatzbereiches der Dekorpaneele können diese aus unterschiedlichen Materialen gefertigt sein. Insbesondere kann dabei das Material des Trägers in Abhängigkeit des Einsatzbereichs gewählt sein. So kann der Träger beispielsweise aus einem Holzwerkstoff bestehen, sofern das Dekorpaneele keiner übermäßigen Feuchtigkeit oder Witterungsbedingungen ausgesetzt ist. Soll das Paneel hingegen z.B. in Feuchträumen oder im Außenbereich eingesetzt werden, kann der Träger beispielsweise aus einem Kunststoff bestehen.Depending on the desired field of application of the decorative panels, these can be made of different materials. In particular, the material of the carrier can be selected depending on the field of application. For example, the support may be made of wood-based material unless the decorative panel is exposed to excessive moisture or weather conditions. On the other hand, if the panel is to be e.g. used in wet rooms or outdoors, the carrier may for example consist of a plastic.

Holzwerkstoffe im Sinne der Erfindung sind dabei neben Vollholzwerkstoffen auch Materialien wie z.B. Brettsperrholz, Brettschichtholz, Stabsperrholz, Funiersperrholz, Furnierschichtholz, Funierstreifenholz und Biegesperrholz. Darüber hinaus sind unter Holzwerkstoffen im Sinne der Erfindung auch Holzspanwerkstoffe wie z.B. Spanpressplatten, Strangpressplatten, Grobspanplatten (Oriented Structural Board, OSB) und Spanstreifenholz sowie auch Holzfaserwerkstoffe wie z.B. Holzfaserdämmplatten (HFD), mittelharte und harte Faserplatten (MB, HFH), sowie insbesondere mitteldichte Faserplatten (MDF) und hochdichte Faserplatten (HDF) zu verstehen. Auch moderne Holzwerkstoffe wie Holz-Polymer-Werkstoffe (Wood Plastic Composite, WPC), Sandwichplatten aus einem leichten Kernmaterial wie Schaumstoff, Hartschaum oder Papierwaben und einer darauf aufgebrachten Holzschicht, sowie mineralisch, z.B. mit Zement, gebundene Holzspanplatten bilden Holzwerkstoffe im Sinne der Erfindung. Auch Kork stellt dabei einen Holzwerkstoff im Sinne der Erfindung dar.For the purposes of the invention, wood-based materials in addition to solid wood materials are also materials such as e.g. Cross laminated timber, glued laminated timber, composite plywood, laminated plywood, veneer plywood, veneer plywood and bent plywood. In addition, wood-base materials within the meaning of the invention also include wood-chip materials, such as wood-based materials. Chipboard, extruded sheet, Oriented Structural Board (OSB) and chipboard wood, as well as wood fiber materials such as Wood fiber insulation boards (HFD), medium-hard and hard fiberboard (MB, HFH), and in particular medium-density fiberboard (MDF) and high-density fibreboard (HDF) to understand. Also, modern wood materials such as wood-plastic composites (WPC), sandwich panels of a lightweight core material such as foam, rigid foam or paper honeycomb and a wooden layer applied thereto, and mineral, e.g. with cement, bonded chipboards form wood materials in the context of the invention. Cork also represents a wood material in the context of the invention.

Kunststoffe, welche bei der Herstellung entsprechender Paneele eingesetzt werden können, sind beispielsweise thermoplastische Kunststoffe, wie Polyvinylchlorid, Polyolefine (beispielsweise Polyethylen (PE), Polypropylen (PP), Polyamide (PA), Polyurethane (PU), Polystyrol (PS), Acrylnitril-Butadien-Styrol (ABS), Polymethylmethacrylat (PMMA), Polycarbonat (PC), Polyethylenterephthalat (PET), Polyetheretherketon (PEEK) oder Mischungen oder Co-Polymerisate dieser. Die Kunststoffe können übliche Füllstoffe enthalten, beispielsweise Kalziumcarbonat (Kreide), Aluminiumoxid, Kieselgel, Quarzmehl, Holzmehl, Gips. Auch können sie in bekannter Weise eingefärbt sein.Plastics which can be used in the production of corresponding panels are, for example, thermoplastics, such as polyvinyl chloride, polyolefins (for example polyethylene (PE), polypropylene (PP), polyamides (PA), polyurethanes (PU), polystyrene (PS), acrylonitrile). Butadiene-styrene (ABS), polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), polyetheretherketone (PEEK) or Mixtures or copolymers of these. The plastics may contain conventional fillers, for example calcium carbonate (chalk), alumina, silica gel, quartz flour, wood flour, gypsum. Also, they can be colored in a known manner.

Unter dem Begriff "Direktdruck" wird im Sinne der Erfindung das Aufbringen eines Dekors direkt auf den Träger eines Paneels oder auf eine auf dem Träger aufgebrachte nicht bedruckte Faserwerkstoffschicht verstanden. Entgegen der konventionellen Verfahren, bei welchen auf einen Träger eine zuvor mit einem gewünschten Dekor bedruckte Dekorschicht aufgebracht wird, erfolgt beim Direktdruck das Aufdrucken des Dekors unmittelbar im Zuge der Paneel-Herstellung. Dabei können unterschiedliche Drucktechniken, wie beispielsweise Flexo-Druck, Offset-Druck oder Siebdruck zum Einsatz gelangen. Insbesondere können dabei Digitaldrucktechniken, wie beispielsweise Inkjet-Verfahren oder Laserdruck-Verfahren eingesetzt werden.For the purposes of the invention, the term "direct printing" refers to the application of a decoration directly to the support of a panel or to a non-printed fiber material layer applied to the support. Contrary to the conventional method, in which a previously printed with a desired decor decorative layer is applied to a carrier, the printing of the decoration takes place during direct printing directly in the course of panel production. In this case, different printing techniques, such as flexographic printing, offset printing or screen printing can be used. In particular, digital printing techniques such as, for example, inkjet methods or laser printing methods can be used.

Im Sinne der Erfindung sind unter dem Begriff Faserwerkstoffe Materialien wie z.B. Papier und Vliese auf Basis pflanzlicher, tierische, mineralischer oder auch künstlicher Fasern zu verstehen, ebenso wie Pappen. Beispiele sind Faserwerkstoffe aus pflanzlichen Fasern sind neben Papieren und Vliesen aus Zellstofffasern Platten aus Biomasse wie Stroh, Maisstroh, Bambus, Laub, Algenextrakte, Hanf, Baumwolle oder Ölpalmenfasern. Beispiele für tierische Faserwerkstoffe sind keratinbasierte Materialien wie z.B. Wolle oder Rosshaar. Beispiele für mineralische Faserwerkstoffe sind aus Mineralwolle oder Glaswolle.For the purposes of the invention, by the term fiber materials, materials such as e.g. Paper and nonwovens based on vegetable, animal, mineral or even artificial fibers to understand, as well as cardboard. Examples are fibrous materials made of vegetable fibers, in addition to papers and webs of cellulose fibers, plates of biomass such as straw, maize straw, bamboo, leaves, algae extracts, hemp, cotton or oil palm fibers. Examples of animal fiber materials are keratin-based materials such as e.g. Wool or horsehair. Examples of mineral fiber materials are mineral wool or glass wool.

Zum Schutz der aufgebrachten Dekorschicht sind in der Regel Verschleiß- oder Deckschichten oberhalb der Dekorschicht aufgebracht. Eine Verschleiß- und/oder Deckschicht im Sinne der Erfindung ist eine als äußerer Abschluss aufgebrachte Schicht, welche insbesondere die Dekorschicht vor Abnutzung oder Beschädigung durch Schmutz, Feuchtigkeitseinfluss oder mechanische Einwirkungen wir beispielsweise Abrieb schützt. Dabei kann es vorgesehen sein, dass die Verschleißschicht Hartstoffe wie beispielsweise Titannitrid, Titancarbid, Siliciumnitrid, Siliciumcarbid, Borcarbid, Wolframcarbid, Tantalcarbid, Aluminiumoxid (Korund), Zirconiumoxid oder Mischungen dieser aufweist, um die Verschleißfestigkeit der Schicht zu erhöhen. Dabei kann es vorgesehen sein, dass der Hartstoff in einer Menge zwischen 5 Gew.-% und 40 Gew.-%, vorzugsweise zwischen 15 Gew.-% und 25 Gew.-% in der Verschleißschichtzusammensetzung enthalten ist. Vorzugsweise weist der Hartstoff dabei einen mittleren Korndurchmesser zwischen 10 µm und 250 µm, weiter vorzugsweise zwischen 10µm und 100µm auf. Hierdurch wird vorteilhafter Weise erreicht, dass die Verschleißschichtzusammensetzung eine stabile Dispersion ausbildet und eine Entmischung bzw. ein Absetzten des Hartstoffes in der Verschleißschichtzusammensetzung vermieden werden kann. Zur Ausbildung einer entsprechenden Verschleißschicht ist es in einer Ausgestaltung der Erfindung vorgesehen, dass die Hartstoff enthaltende und strahlungshärtbare Zusammensetzung in einer Konzentration zwischen 10 g/m2 und 250 g/m2, vorzugsweise zwischen 25 g/m2 und 100g/m2 aufgetragen wird. Dabei kann die Auftragung beispielsweise mittels Walzen, wie Gummiwalzen oder mittels Gießvorrichtungen aufgetragen werden. In einer weiteren Ausgestaltung der Erfindung kann es vorgesehen sein, dass der Hartstoff zum Zeitpunkt des Auftrages der Verschleißschichtzusammensetzung nicht in der Zusammensetzung enthalten ist, sondern als Partikel auf die aufgetragenen Verschleißschichtzusammensetzung aufgestreut wird und diese im Anschluss gehärtet wird.To protect the applied decorative layer wear or cover layers are usually applied above the decorative layer. A wearing and / or covering layer in the sense of the invention is a layer applied as an outer finish, which in particular protects the decorative layer from abrasion or damage by dirt, moisture or mechanical effects such as abrasion. It may be provided that the wear layer hard materials such as Titanium nitride, titanium carbide, silicon nitride, silicon carbide, boron carbide, tungsten carbide, tantalum carbide, alumina (corundum), zirconium oxide, or mixtures thereof to increase the wear resistance of the layer. It may be provided that the hard material in an amount between 5 wt .-% and 40 wt .-%, preferably between 15 wt .-% and 25 wt .-% in the wear layer composition is included. The hard material preferably has an average particle diameter between 10 μm and 250 μm, more preferably between 10 μm and 100 μm. In this way, it is advantageously achieved that the wear layer composition forms a stable dispersion and segregation or settling of the hard material in the wear layer composition can be avoided. To form a corresponding wear layer, it is provided in one embodiment of the invention that the hard material-containing and radiation-curable composition in a concentration between 10 g / m 2 and 250 g / m 2 , preferably between 25 g / m 2 and 100g / m 2 applied becomes. In this case, the application can be applied for example by means of rollers, such as rubber rollers or by means of pouring devices. In a further embodiment of the invention, it may be provided that the hard material is not present in the composition at the time of application of the wear layer composition, but is scattered as particles onto the applied wear layer composition and this is subsequently cured.

Vielfach ist es vorgesehen, dass in solche Verschleiß- oder Deckschichten eine mit dem Dekor übereinstimmende Oberflächenstrukturierung eingebracht ist. Unter einer mit dem Dekor übereinstimmenden Oberflächenstrukturierung ist zu verstehen, dass die Oberfläche des Dekorpaneels eine haptisch wahrnehmbare Struktur aufweist, welche ihrer Form und ihrem Muster dem aufgebrachten Dekor entspricht, um so eine möglichst originalgetreue Nachbildung eines natürlichen Werkstoffes auch hinsichtlich der Haptik zu erhalten. Dabei kann es vorgesehen sein, dass Trägerplatte bereits eine Strukturierung aufweist und eine Ausrichtung eines Druckwerkzeuges zur Aufbringung des Dekors und der Trägerplatte zueinander in Abhängigkeit mittels der mittels optischer Verfahren erfassten Strukturierung der Trägerplatte erfolgt. Zur Ausrichtung des Druckwerkzeuges und der Trägerplatte zueinander kann es dabei vorgesehen sein, dass eine zur Ausrichtung notwendige Relativbewegung zwischen Druckwerkzeug und Trägerplatte zueinander durch eine Verschiebung der Trägerplatte oder durch eine Verschiebung des Druckwerkzeugs erfolgt. Gemäß einer weiteren Ausgestaltung der Erfindung ist es vorgesehen, dass eine Strukturierung der Dekorpaneele nach dem Auftrag der Deck- und/oder Verschleißschicht erfolgt. Hierzu kann es bevorzugt vorgesehen sein, dass als Deck- und/oder Verschleißschicht eine härtbare Zusammensetzung aufgetragen wird und ein Aushärtungsprozess nur in dem Maße erfolgt, dass lediglich eine Teilhärtung der Deck- und/oder Verschleißschicht erfolgt. In die so teilgehärtete Schicht wird mittels geeigneter Werkzeuge, wie beispielsweise einer Hartmetall-Strukturwalze oder eines Stempels, eine gewünschte Oberflächenstruktur eingeprägt. Dabei erfolgt die Prägung in Übereinstimmung mit dem aufgebrachten Dekor. Zur Gewährleistung einer hinreichenden Übereinstimmung der einzubringenden Struktur mit dem Dekor kann es vorgesehen sein, dass die Trägerplatte und das Prägewerkzeug durch entsprechende Relativbewegungen zueinander ausgerichtet werden. Im Anschluss an die Einbringung der gewünschten Struktur in die teilgehärtete Deck- und/oder Verschleißschicht erfolgt eine weitere Härtung der nun strukturierten Deck- und/oder Verschleißschicht.In many cases it is provided that in such wear or cover layers a matching with the decor surface structuring is introduced. Under a matching with the decor surface structuring is to be understood that the surface of the decorative panel has a haptic perceptible structure which corresponds to the shape and pattern of the applied decor, so as to obtain a true to the original reproduction of a natural material also in terms of haptics. It may be provided that the carrier plate already has a structuring and alignment of a printing tool for applying the decoration and the support plate to each other in dependence on the detected by means of optical methods structuring of the carrier plate. For aligning the pressure tool and the support plate to each other, it may be provided that a necessary relative to the orientation relative movement between the pressure tool and support plate to each other by a displacement of the support plate or by a displacement of the pressure tool. According to a further embodiment of the invention, it is provided that a structuring of the decorative panels after the application of the cover and / or wear layer takes place. For this purpose, it can preferably be provided that a curable composition is applied as cover and / or wear layer and a curing process takes place only to the extent that only partial hardening of the cover and / or wear layer takes place. In the thus partially cured layer, a desired surface structure is impressed by means of suitable tools, such as a hard metal structural roller or a stamp. The embossing is done in accordance with the applied decor. In order to ensure sufficient conformity of the structure to be introduced with the decor, provision may be made for the carrier plate and the embossing tool to be aligned with one another by corresponding relative movements. Subsequent to the introduction of the desired structure into the partially cured cover and / or wear layer, a further hardening of the now structured covering and / or wear layer takes place.

Ein Problem, welches beim direkten Bedrucken von Dekorpaneelen auftreten kann, ist das im Laufe des Produktionsprozesses eine Verschlechterung des Druckbildes auftritt. In Abhängigkeit des gewählten Druckverfahrens kann es während des Produktionsprozesses zu einer sichtbaren Unschärfe des Druckbildes kommen. Wird beispielsweise ein Inkjet-Verfahren bzw. Tintenstrahlverfahren zur Aufbringung des Dekors verwendet, tritt nach einem gewissen Produktionszeitrum eine deutliche Unschärfe im Dekordruck auf, welche nicht auf etwaige Verschmutzungen des Druckkopfes oder Veränderung der Druckfarbe zurückzuführen ist.A problem that can occur when direct printing on decorative panels, is that during the production process deterioration of the printed image occurs. Depending on the selected printing process, there may be a visible blurring of the printed image during the production process. If, for example, an inkjet method or inkjet method is used to apply the decoration, after a certain production time a clear blurring of the decor pressure occurs, which is not due to any soiling of the print head or change in the printing ink.

Dies berücksichtigend ist es die Aufgabe der vorliegenden Erfindung, eine Vorrichtung und ein Verfahren anzugeben, welche das aus dem Stand der Technik bekannte Problem zu überwinden vermögen.With this in mind, it is the object of the present invention to provide an apparatus and a method which can overcome the problem known from the prior art.

Gelöst wir diese Aufgabe durch eine Vorrichtung gemäß Anspruch 1 sowie ein Verfahren gemäß Anspruch 4. Ausgestaltungen der Erfindung finden sich in den abhängigen Ansprüchen sowie der weiteren Beschreibung.We solve this object by a device according to claim 1 and a method according to claim 4. Embodiments of the invention can be found in the dependent claims and the further description.

Mit der Erfindung wird somit eine Paneelbedruckungsvorrichtung vorgeschlagen, welche eine Zuführeinrichtung für einen zu bedruckenden Träger und ein Druckwerk aufweist, wobei die Paneelbedruckungsvorrichtung wenigstens eine Einrichtung zur Ableitung elektrostatischer Ladungen aus dem Träger aufweist.The invention thus proposes a panel printing device which has a feed device for a carrier to be printed and a printing unit, wherein the panel printing device has at least one device for discharging electrostatic charges from the carrier.

Überraschender Weise hat sich gezeigt, dass das Vorsehen einer Einrichtung zur Ableitung elektrostatischer Ladungen aus den zu bedruckenden Trägern geeignet ist, das Auftreten von Unschärfen im Laufe des Produktionsprozesses zu vermeiden. Die sich im Laufe des Produktionsprozesses aufbauende elektrostatische Ladung in den zu bedruckenden Trägern führt zu einer Ablenkung der Farb- bzw. Tintentropfen auf Ihrem Weg vom Druckkopf zur zu bedruckenden Oberfläche. Dabei wird davon ausgegangen, dass das sich aufbauende elektrostatische Feld auf den Trägern die in der Regel positiv geladenen Farbpartikel ablenkt, so dass diese nicht auf dem vorgesehenen Punkt der zu bedruckenden Oberfläche auftreffen. Die so hervorgerufene Ungenauigkeit des Farbauftrags führt zu der wahrnehmbaren Unschärfe des Druckbildes. In Abhängigkeit der Produktionsgeschwindigkeit und des gewählten Trägermaterials tritt dieser Effekt in unterschiedlicher Ausprägung auf, so dass davon ausgegangen wird, dass die Träger, in Abhängigkeit des Trägermaterials, durch den Transport innerhalb der Fertigungsanlage elektrostatisch aufgeladen werden und diese Aufladung hinreichend ist, um den beobachteten Effekt hervorzurufen.Surprisingly, it has been found that the provision of a device for dissipating electrostatic charges from the substrates to be printed is suitable for avoiding the occurrence of blurring in the course of the production process. The build-up of electrostatic charge in the substrates during the production process leads to a distraction of the ink or ink droplets on their way from the print head to the surface to be printed. It is assumed that the constituent electrostatic field on the carriers deflects the generally positively charged color particles so that they do not hit the intended point on the surface to be printed. The thus caused inaccuracy of the ink application leads to the noticeable blurring of the printed image. Depending on the production speed and the selected carrier material, this effect occurs to a different extent, so that it is assumed that the carriers, depending on the carrier material, are electrostatically charged by the transport within the production plant and this charge is sufficient to the observed effect cause.

In der Erfindung ist es vorgesehen, dass die Einrichtung zur Ableitung elektrostatischer Ladungen wenigstens eine Rolle, Bürste oder Lippe aus einem leitfähigen Material aufweist, welche den Träger zumindest im Bereich des Druckwerks elektrisch leitend kontaktiert und welche mit einem elektrischen Massenpotential verbunden ist. Dabei kann das elektrische Massenpotential beispielsweise durch eine Erdung bereitgestellt werden.In the invention, it is provided that the device for discharging electrostatic charges comprises at least one roller, brush or lip made of a conductive material, which electrically conductively contacts the carrier at least in the region of the printing unit and which is connected to an electrical ground potential. In this case, the electrical ground potential can be provided for example by a ground.

In einer Ausgestaltung der Erfindung ist es vorgesehen, dass die Ausleitung der elektrostatischen Aufladung über eine Rolle erfolgt, welche Bestandteile der Zuführeinrichtung zum Druckwerk ist. Hierdurch kann eine kompakte Bauweise der Vorrichtung erreicht werden. Gemäß einer besonders bevorzugten Ausgestaltung der Erfindung kann es dabei vorgesehen sein, dass eine Mehrzahl der zum Transport der Träger innerhalb einer Fertigungsstrecke zur Herstellung von Dekorpaneelen vorhandenen Rollen derart ausgeführt ist, dass über diese etwaige auftretende elektrostatische Ladungen ausgeleitet werden können.In one embodiment of the invention, it is provided that the discharge of the electrostatic charge takes place via a roller, which is part of the feed device to the printing unit. This allows a compact design of the device can be achieved. According to a particularly preferred embodiment of the invention, it may be provided that a plurality of existing for transporting the carrier within a manufacturing line for the production of decorative panels rollers is designed such that it can be discharged via this any occurring electrostatic charges.

Die Rolle, Bürste oder Lippe ist vorzugsweise zumindest im Kontaktbereich mit dem Träger aus einem Material mit einer Leitfähigkeit ≥ 1*103 Sm-1 gebildet. Insbesondere kann es dabei vorgesehen sein, dass der elektrische Widerstand zwischen Träger und Massenpotential ≤ 0,5 Ω, vorzugsweise ≤ 0,05 Ω ist.The roller, brush or lip is preferably formed at least in the contact region with the carrier of a material having a conductivity ≥ 1 * 10 3 Sm -1 . In particular, it may be provided that the electrical resistance between the carrier and the ground potential is ≦ 0.5 Ω, preferably ≦ 0.05 Ω.

Die Rolle, Bürste oder Lippe, mittels welcher der Träger kontaktiert wird kann beispielsweise im Kontaktbereich mit dem Träger aus einem elektrisch leitfähigen Metall wie Stahl, Chrom, Kupfer, Aluminium, Silber oder einer leitfähigen Legierung wie Messing oder Bronze gebildet sein. Gemäß einer weiteren Ausgestaltung der Erfindung besteht die Rolle, Bürste oder Lippe zumindest teilweise aus einem elektrisch leitfähigen Kunststoff. Beispiele für geeignete elektrisch leitfähige Kunststoffe sind Poly-3,4-ethylendioxythiophen, dotiertes Polythiophen, dotiertes Polyethin, Polyanilin und Polypyrrol. Ein Vorteil solcher leitfähiger Kunststoffe gegenüber Metallen ist, dass die Kunststoffe weicher als die Metalle sind, wodurch eine etwaige Beschädigung des Trägers durch verkratzen vermieden werden kann.The roller, brush or lip, by means of which the carrier is contacted, may for example be formed in the contact region with the carrier of an electrically conductive metal such as steel, chromium, copper, aluminum, silver or a conductive alloy such as brass or bronze. According to a further embodiment of the invention, the roller, brush or lip at least partially made of an electrically conductive plastic. Examples of suitable electrically conductive plastics are poly-3,4-ethylenedioxythiophene, doped polythiophene, doped polyethyne, polyaniline and polypyrrole. An advantage of such conductive plastics over metals is that the plastics are softer than the metals, thereby avoiding any damage to the backing by scratching.

Alternativ kann es vorgesehen sein, dass die Rolle, Bürste oder Lippe zumindest an den Kontaktstellen mit dem Träger aus einem leitfähigen Gewebe besteht. Dies kann beispielsweise ein Kunststoffgewebe sein, in welches Metallfäden eingewebt sind.Alternatively, it can be provided that the roller, brush or lip at least at the contact points with the carrier consists of a conductive fabric. This can be for example a plastic fabric, in which metal threads are woven.

Gemäß der Erfindung kann es vorgesehen sein, dass die Paneelbedruckungsvorrichtung eine dem Druckwerk vorgelagerte Ionisierungseinrichtung aufweist, mittels welcher ein ionisierter Luftstrahl über den zu bedruckenden Träger geleitet wird. Es hat sich gezeigt, dass die Beaufschlagung mit ionisierter Luft geeignet ist, das Auftreten von elektrostatischer Aufladung der Träger weiter zu verringern.According to the invention, it may be provided that the panel printing device has an upstream of the printing unit ionization, by means of which an ionized air jet is passed over the substrate to be printed. It has been found that the application of ionized air is suitable for further reducing the occurrence of electrostatic charging of the carriers.

Gemäß einer Ausgestaltung des Verfahrens umfassen die Mittel zur Verringerung der elektrostatischen Aufladung die elektrisch leitfähige Kontaktierung des Trägers mit einem Massenpotential. Hierzu kann es vorgesehen sein, dass die Kontaktierung des Trägers mittels einer Rolle, Bürste oder Lippe aus einem Material mit einer elektrischen Leitfähigkeit ≥ 1*103 Sm-1 erfolgt.According to one embodiment of the method, the means for reducing the electrostatic charge comprise the electrically conductive contacting of the carrier with a ground potential. For this purpose, it can be provided that the contacting of the carrier by means of a roller, brush or lip made of a material having an electrical conductivity ≥ 1 * 10 3 Sm -1 .

Gemäß einer weiteren Ausgestaltung des erfindungsgemäßen Verfahrens kann es vorgesehen sein, dass der Träger vor und/oder während der Zuführung zum Druckwerk mit einem ionisierten Luftstrom beaufschlagt wird. Es hat sich gezeigt, dass die Beaufschlagung mit einem ionisierten Luftstrom geeignet ist, eine elektrostatische Aufladung in den Trägern signifikant zu verringern.According to a further embodiment of the method according to the invention, it can be provided that the carrier is subjected to an ionized air flow before and / or during the feed to the printing unit. It has been found that the application of an ionized air stream is suitable for significantly reducing electrostatic charge in the substrates.
