Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines plattenförmigen Produktes mit einer ein Dekor aufweisenden Oberfläche, bei dem auf einen Grundkörper, der aus einer Trägerplatte aus Holzwerkstoff, aus Schichtstoff und/oder aus einer Compactplatte gebildet ist, mittels mindestens eines Druckwalzenwerkes ein Dekor gedruckt wird, nach dem Oberbegriff des Anspruchs 1. Des Weiteren betrifft die Erfindung eine Vorrichtung zur Herstellung eines plattenförmigen Produktes mit einer ein Dekor aufweisenden Oberfläche, mit mindestens einem Druckwalzenwerk zum Drucken eines Dekors auf einen Grundkörper, der aus einer Trägerplatte aus Holzwerkstoff, aus Schichtstoff und/oder aus einer Compactplatte gebildet ist, nach dem Oberbegriff des Anspruchs 11.The invention relates to a method for producing a plate-shaped product with a surface having a decor, in which on a base body, which is formed from a carrier plate made of wood material, made of laminate and / or from a compact plate, by means of at least one printing cylinder unit a decor is printed, According to the preamble of claim 1. Furthermore, the invention relates to an apparatus for producing a plate-shaped product having a decorative surface, with at least one printing roller for printing a decoration on a base body, which consists of a carrier plate of wood material, of laminate and / or is formed from a compact plate, according to the preamble of claim 11.

Verfahren und Vorrichtungen zum direkten Aufdrucken eines Holzdekors auf Holzwerkstoffplatten sind bekannt. Sie bieten gegenüber dem gängigen Stand der Technik, bei dem dekorative Oberflächen auf Holzwerkstoffplatten durch Beschichten derselben mit bedruckten Papieren erreicht werden, unter anderem den Vorteil, dass eine Gegenzugschicht auf der Rückseite der Platte überflüssig ist. Dadurch können die Herstellungskosten für entsprechende, ein Dekor aufweisende Holzwerkstoffplatten reduziert werden.Methods and devices for direct printing a wood decor on wood-based panels are known. They offer over the current state of the art, in which decorative surfaces are achieved on wood-based panels by coating them with printed papers, including the advantage that a Gegenzugschicht on the back of the plate is unnecessary. As a result, the production costs for corresponding, a decor having wood-based panels can be reduced.

In der auf die Anmelderin zurückgehenden WO 2006/002917 A2 ist beispielsweise ein Verfahren zum Herstellen einer Platte mit einer ein Dekor aufweisenden Oberfläche beschrieben, wobei die Platte aus einem auf lignozellulosem Material basierenden Trägerwerkstoff besteht. Bei diesem bekannten Verfahren wird eine bereits geschliffene, mit einem Dekor, insbesondere einem Holzdekor zu versehene Oberfläche grundiert, danach geglättet und anschließend zum Erzeugen des Dekors mittels Druckwalzen (Druckzylinder) im Tiefdruckverfahren direkt bedruckt.In the case of the applicant WO 2006/002917 A2 For example, there is described a method of making a panel having a decorative surface, the panel being of a lignocellulosic material-based support material. In this known method, an already ground, to be provided with a decor, in particular a wood decor to be primed surface, then smoothed and then printed directly to produce the decor by means of pressure rollers (printing cylinder) in gravure printing.

Zum Herstellen von Paneelen mit dekorativen Oberflächen werden neben Walzendruckverfahren auch Digitaldruckverfahren verwendet. So ist zum Beispiel aus der WO 98/26936 A1 ein Verfahren zum Herstellen von harzgetränkten Dekorpapieren zur Beschichtung von Trägerplatten bekannt. Die so beschichteten Trägerplatten (Laminate) sind insbesondere für den Möbelbau bestimmt. Bei dem bekannten Verfahren wird harzgetränktes Papier mittels eines Digitaldruckers, insbesondere Laserdruckers mit einem digitalen Bild bedruckt.For the production of panels with decorative surfaces, in addition to roller printing processes, digital printing processes are also used. So is for example from the WO 98/26936 A1 a method for producing resin-impregnated decorative paper for coating carrier plates known. The so coated carrier plates (laminates) are intended especially for the furniture industry. In the known method, resin-impregnated paper is printed by means of a digital printer, in particular laser printer with a digital image.

Walzendruckverfahren sind aufgrund ihrer hohen Druckgeschwindigkeit für die Herstellung großer Mengen von dekorativen Paneelen gut geeignet. Hinsichtlich der Herstellung von Paneelen, insbesondere Fußbodenpaneelen, kommt es bei Walzendruckverfahren typischerweise zur Wiederholung des aufgedruckten Dekors. Die Häufigkeit der Wiederholung des Dekors kann grundsätzlich nur durch den Durchmesser sowie die Länge der Druckwalzen beeinflusst werden. Beide Parameter können jedoch nicht beliebig variiert werden, sondern sind aus technischen Gründen beschränkt. Digitaldruckverfahren verfügen dagegen grundsätzlich über eine unbeschränkte Möglichkeit zur Individualisierung des Dekors. Die Individualisierungsmöglichkeit ist im Wesentlichen nur von der zur Verfügung gestellten Speicherkapazität zum Vorhalten der digitalen Dekordaten, der aktuell verfügbaren Rechnerleistung sowie der schöpferischen Leistung der Dekorentwickler abhängig. Andererseits sind Digitaldruckverfahren jedoch vergleichsweise teuer, da die mit einer Digitaldruckanlage erreichbare Mengenleistung beschränkt und relativ gering ist.Roller printing processes are well suited for the production of large quantities of decorative panels due to their high printing speed. With regard to the production of panels, in particular floor panels, roller printing processes typically result in the repetition of the printed decoration. The frequency of repetition of the decoration can basically only be influenced by the diameter and the length of the pressure rollers. However, both parameters can not be varied arbitrarily, but are limited for technical reasons. In contrast, digital printing methods basically have an unlimited possibility to customize the decor. The possibility of individualization essentially depends only on the storage capacity made available for holding the digital decor data, the currently available computer performance and the creative performance of the decor developers. On the other hand, however, digital printing methods are comparatively expensive since the quantity output achievable with a digital printing system is limited and relatively low.

Aus der US 2005/249924 A1 ist ein Verfahren zur Herstellung einer dekorativen Oberflächenbeschichtung bekannt, bei dem eine erste Druckschicht mittels eines Druckwalzenwerkes und eine darauf folgende zweite Druckschicht mittels eines Digitaldruckkopfes erzeugt wird. Die Druckschichten werden dabei direkt auf ein Substrat, z.B. eine Trägerplatte, gedruckt, oder zunächst auf ein Papier oder eine Folie gedruckt, die/das anschließend auf ein Substrat, z.B. eine Trägerplatte, geklebt wird.From the US 2005/249924 A1 For example, a method for producing a decorative surface coating is known in which a first printing layer is produced by means of a printing drum unit and a subsequent second printing layer by means of a digital printing head. The print layers are printed directly onto a substrate, for example a support plate, or initially printed on a paper or a film, which is then glued to a substrate, for example a support plate.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs genannten Art anzugeben, die bei relativ hoher Mengenleistung bzw. günstigen Herstellungskosten eine unbeschränkte Möglichkeit zur Individualisierung des Dekors bieten.The present invention has for its object to provide a method and an apparatus of the type mentioned above, which offer an unlimited possibility for customization of the decor at relatively high flow rate or low production costs.

Gelöst wird diese Aufgabe durch ein Verfahren mit den Merkmalen des Anspruchs 1 bzw. durch eine Vorrichtung mit den Merkmalen des Anspruchs 11.This object is achieved by a method having the features of claim 1 or by a device having the features of claim 11.

Das erfindungsgemäße Verfahren, bei dem mittels mindestens eines Druckwalzenwerkes ein Dekor auf einen aus einer Trägerplatte aus Holzwerkstoff, aus Schichtstoff und/oder aus einer Compactplatte gebildeten Grundkörper gedruckt wird, und bei dem mittels mindestens eines Digitaldruckkopfes mindestens ein Dekorelement auf einen oder mehrere Teilbereiche des Grundkörpers gedruckt wird, so dass das mittels des mindestens einen Druckwalzenwerkes aufgedruckte Dekor zumindest teilweise sichtbar bleibt oder, sofern das mindestens eine Dekorelement mittels des mindestens einen Digitaldruckkopfes zeitlich vor dem Dekor auf den Grundkörper aufgedruckt wird, das mindestens eine Dekorelement umgibt, ist dadurch gekennzeichnet, dass der mindestens eine Digitaldruckkopf mit dem Grundkörper in dessen Vorschubrichtung verfahren wird.The inventive method, wherein by means of at least one printing roller work a decor on one of a Support plate made of wood material, laminate and / or printed compact disk is printed, and is printed by means of at least one digital printhead at least one decorative element on one or more portions of the body, so that the printed by means of at least one printing roller unit decor at least partially visible remains or, if the at least one decorative element is printed by means of the at least one digital printhead in front of the decor on the body that surrounds at least one decorative element is characterized in that the at least one digital printhead is moved with the main body in the feed direction.

Hierdurch kann dem Digitaldruckkopf mehr Zeit zum Drucken des jeweiligen Dekorelements gegeben werden, so dass die hohe Druckgeschwindigkeit des mindestens einen Druckwalzenwerkes trotz der herkömmlich vergleichsweise geringeren Druckgeschwindigkeit des Digitaldruckkopfes dennoch beibehalten werden kann.In this way, more time can be given to the digital print head for printing the respective decorative element, so that the high printing speed of the at least one printing cylinder unit can still be maintained despite the conventionally comparatively lower printing speed of the digital print head.

Die erfindungsgemäße Vorrichtung, die mindestens ein Druckwalzenwerk zum Drucken eines Dekors auf einen aus einer Trägerplatte aus Holzwerkstoff, aus Schichtstoff und/oder aus einer Compactplatte gebildeten Grundkörper aufweist, umfasst dementsprechend mindestens einen Digitaldruckkopf zum Drucken mindestens eines Dekorelements auf einen oder mehrere Teilbereiche des Grundkörpers, so dass das mittels des mindestens einen Druckwalzenwerkes aufgedruckte Dekor zumindest teilweise sichtbar bleibt oder, sofern das mindestens eine Dekorelement mittels des mindestens einen Digitaldruckkopfes zeitlich vor dem Dekor auf den Grundkörper aufgedruckt wird, das mindestens eine Dekorelement umgibt, und ist dadurch gekennzeichnet, dass der mindestens eine Digitaldruckkopf mit dem Grundkörper in dessen Vorschubrichtung verfahrbar ist.The device according to the invention, which has at least one printing roller unit for printing a decoration on a main body formed of a wooden board, laminate and / or compact panel, accordingly comprises at least one digital printhead for printing at least one decorative element on one or more partial areas of the main body, so that the decor printed by means of the at least one printing roller unit remains at least partially visible or, provided that the at least one decorative element by means of the at least one digital print head in time before the decoration on the base body is printed, which surrounds at least one decorative element, and is characterized in that the at least one digital print head with the main body in the feed direction is movable.

Die Erfindung basiert somit auf der Idee, Tiefdruck und Digitaldruck miteinander zu kombinieren, um plattenförmige Grundkörper, insbesondere Holzwerkstoffplatten, beispielsweise als Fußbodendielen, mit einer ein Dekor aufweisenden Oberfläche herzustellen.The invention is thus based on the idea of combining intaglio and digital printing with one another in order to produce plate-shaped base bodies, in particular wood-based panels, for example as floorboards, with a surface having a decoration.

Eine Digitaldruckanlage zum vollflächigen Bedrucken der Oberseite einer Trägerplatte besitzt eine relativ geringe Druckgeschwindigkeit. Bei dem erfindungsgemäßen Verfahren bzw. der erfindungsgemäßen Vorrichtung wird der mindestens eine Digitaldruckkopf allerdings nur zum partiellen Bedrucken der Oberseite eines plattenförmigen Grundkörpers bzw. einer Trägerplatte verwendet, so dass die Druckgeschwindigkeit und damit die Leistung höher ist als bei einer Anlage, die ausschließlich Digitaldruck anwendet.A digital printing system for full-surface printing of the top of a carrier plate has a relatively low printing speed. In the method according to the invention or the device according to the invention, however, the at least one digital print head is only used for partial printing of the upper side of a plate-shaped main body or a carrier plate, so that the printing speed and thus the performance is higher than in a system which exclusively uses digital printing.

Die für eine Digitaldruckanlage erforderlichen Farben (Tinten) kosten ein Vielfaches der Druckfarben, die in gattungsgemäßen Tiefdruckanlagen eingesetzt werden können. Gegenüber einer Digitaldruckanlage zum vollflächigen Bedrucken der Oberseite einer Trägerplatte zeichnet sich die erfindungsgemäße Vorrichtung somit durch wesentlich günstigere Verbrauchskosten aus.The colors required for a digital printing system (inks) cost a multiple of the printing inks that can be used in generic gravure printing systems. Compared to a digital printing system for full-surface printing of the top of a support plate, the device according to the invention thus characterized by much cheaper consumption costs.

Da mittels des mindestens einen Digitaldruckkopfes lediglich ein oder mehrere Teilbereiche des plattenförmigen Grundkörpers mit mindestens einem Dekorelement bedruckt werden, ist hinsichtlich des Digitaldruckes keine Vollreproduktion bezüglich der mit einem Dekor zu versehenden Oberfläche des Grundkörpers erforderlich. Hierdurch ist eine einfachere Softwarearchitektur bzw. Softwareprogrammierung gegenüber einem ausschließlich Digitaldruck anwendenden Verfahren möglich.Since printed by means of the at least one digital printhead only one or more portions of the plate-shaped base body with at least one decorative element are, in terms of digital printing, no full reproduction with respect to the decor to be provided surface of the body required. As a result, a simpler software architecture or software programming compared to a solely digital printing applying method is possible.

Ein weiterer Vorteil der erfindungsgemäßen Lösung ergibt sich in Bezug auf eine bereits vorhandene gravierte Druckwalze, indem das mittels der Druckwalze aufgedruckte Dekor mittels des mindestens einen Digitaldruckkopfes variiert wird. So kann beispielsweise ein mittels einer bereits vorhandenen Druckwalze aufgedrucktes Schiffsbodendekor mittels des mindestens einen Digitaldruckkopfes mit Längs- und Querlinien versehen werden, um auf diese Weise die Fugenoptik des Schiffsbodendekors zu verstärken.A further advantage of the solution according to the invention results in relation to an already existing engraved printing roll in that the decoration printed by means of the printing roll is varied by means of the at least one digital printing head. For example, by means of the at least one digital print head, a ship bottom decoration printed by means of an already existing pressure roller can be provided with longitudinal and transverse lines, in order to reinforce the joint optics of the ship bottom decoration.

Bei dem mindestens einen Dekorelement, welches mittels des mindestens einen Digitaldruckkopfes gedruckt wird, kann es sich um ein oder mehrere Dekorelemente folgender Arten von Dekorelementen handeln:

  1. a) Dekorelemente, welche die Struktur des zu imitierenden Werkstoffes wiedergeben. Das können bei Holz die Maserung, Kern- und Splintholz, Äste, Harzgallen, Fraßgänge, Verfärbungen durch Pilze, Reaktionsholz, etc. sein. Bei Stein können dies verschiedene Verfärbungen, Einschlüsse, Petrefakte, etc. sein.
  2. b) Dekorelemente, welche einzelne Dekorabschnitte voneinander abgrenzen, wie zum Beispiel Fugen zwischen Keramikfliesen oder Stöße zwischen Holzpaneelen.
  3. c) Dekorelemente, die eine separate Abbildung neben einem zu imitierenden Werkstoff bilden, wie zum Beispiel Nagel- oder Schraubenköpfe in einem Holzpaneel, florale Muster auf einem Unidekor oder Schriftzüge und Logos.
  4. d) Dekorelemente, die über mehrere Paneele hinweg ein Muster ergeben, wie zum Beispiel die Darstellung von Randfriesen bei Fußbodenpaneelen oder Straßenzügen bei Spielböden.
The at least one decorative element which is printed by means of the at least one digital print head can be one or more decorative elements of the following types of decorative elements:
  1. a) decorative elements that reflect the structure of the material to be imitated. In the case of wood this can be the grain, core and sapwood, branches, resin galls, feeding ducts, discoloration by fungi, reaction wood, etc. In the case of stone, these can be various discolorations, inclusions, petrefacts, etc.
  2. b) decorative elements that delimit individual decorative sections, such as joints between ceramic tiles or joints between wooden panels.
  3. c) decorative elements that form a separate image next to a material to be imitated, such as nail or screw heads in a wooden panel, floral patterns on a plain decor or logos and logos.
  4. d) decorative elements that give a pattern over several panels, such as the representation of edge friezes in floor panels or streets in playgrounds.

Eine vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass die Druckposition des mindestens einen Dekorelements auf der mit dem Dekor zu versehenden Oberfläche nach einem Zufallsprinzip vorgegeben wird. Bei dem Dekorelement kann es sich insbesondere um die Darstellung eines Astes oder eines anderen typischen Holzmerkmals in einem Holzdekor handeln. Auf diese Weise lassen sich insbesondere Holzdielen nachahmen, wobei eine Wiederholung identisch aussehender Holzdielen durch die zufallsgesteuerte Positionierung des Dekorelements bzw. Astes ausgeschlossen ist.An advantageous embodiment of the invention is characterized in that the printing position of the at least one decorative element is predetermined on the surface to be provided with the decor according to a random principle. In particular, the decoration element may be the representation of a branch or another typical wood feature in a wood decor. In this way, in particular wooden floorboards can be imitated, with a repetition of identical-looking wooden floorboards is excluded by the random positioning of the decorative element or branch.

Alternativ oder ergänzend sieht eine weitere vorteilhafte Ausgestaltung der Erfindung vor, dass das mindestens eine Dekorelement aus einer Gruppe von Dekorelementen nach einem Zufallsprinzip ausgewählt wird. So kann beispielsweise zunächst mittels Walzendruck (Tiefdruck) ein Holzdekor, zum Beispiel ein Kieferdekor auf eine Trägerplatte aus Holzwerkstoff aufgedruckt werden. Mittels eines anschließenden Digitaldruckes werden dann flächig begrenzte Dekorelemente, zum Beispiel Äste, auf das als Basis dienende Holzdekor der Trägerplatte aufgedruckt. Wenn man nun die digitalen Daten einer Vielzahl optisch unterschiedlicher Dekorelemente bzw.Alternatively or additionally, a further advantageous embodiment of the invention provides that the at least one decorative element is selected from a group of decorative elements according to a random principle. Thus, for example, by means of roller pressure (gravure printing), a wood decor, for example a pine decor, may first be printed on a carrier plate of wood-based material. By means of a subsequent digital printing then areal limited decor elements, for example branches, printed on serving as a basis wood decor of the support plate. If one now the digital data of a variety of visually different decorative elements or

Äste in einem entsprechenden Datenspeicher hinterlegt hat und dann per Zufallsgenerator die Variantenauswahl vornimmt, so ergibt sich eine entsprechende Vielzahl unterschiedlicher Dielen. Besonders bevorzugt und vorteilhaft ist eine Kombination einer solchen zufallsgeneratorgesteuerten Auswahl eines Dekorelementes aus der Vielzahl von Varianten mit einer ebenfalls zufallsgeneratorgesteuerten Positionswahl in X-und/oder Y-Richtung, d.h. in Längs- und/oder Querrichtung der jeweiligen Diele. Auf diese Weise kann jede einzelne Diele so gestaltet werden, dass es unmöglich oder nahezu unmöglich ist, unter den so produzierten Dielen zwei identische Dielen zu finden. Dabei kann durch Erweiterung eines bestimmten Typs eines Dekorelements, zum Beispiel von Astabbildungen, durch einen weiteren Typ eines anderen Dekorelements, zum Beispiel andere "Holzfehler" und/oder unterschiedliche Abnutzungsspuren, wie Mattstellen, die Variantenanzahl noch weiter steigert werden.Has deposited branches in a corresponding data store and then randomly performs the variant selection, then results in a corresponding variety of different planks. Particularly preferred and advantageous is a combination of such a random generator controlled selection of a decorative element of the plurality of variants with a randomly controlled position selection in the X and / or Y direction, i. in the longitudinal and / or transverse direction of the respective hallway. In this way, each individual plank can be designed in such a way that it is impossible or almost impossible to find two identical planks among the planks produced in this way. In this case, by extension of a certain type of decorative element, for example of Astabbildungen, by another type of another decorative element, for example, other "wood defects" and / or different signs of wear, such as mats, the number of variants can be further increased.

Die Anwendung der vorliegenden Erfindung ist nicht auf Holzdekore beschränkt. Ebenso lässt sich mit dem erfindungsgemäßen Verfahren auch die Variantenanzahl von mit Stein-, Fliesen- oder anderen Fantasiedekoren bedruckten Holzwerkstoffplatten steigern. So kann beispielsweise ein mittels Walzendruck (Tiefdruck) aufgedrucktes Natursteindekor variiert werden, indem mittels des mindestens einen Digitaldruckkopfes "Einschlüsse" oder sonstige markante Stellen auf das als Basis dienende Natursteindekor aufgedruckt werden.The application of the present invention is not limited to wood designs. Likewise, the number of variants of wood-based panels printed with stone, tile or other fantasy decors can also be increased with the method according to the invention. Thus, by way of example, a natural stone decor printed by means of roller printing (gravure printing) can be varied by printing "inclusions" or other distinctive locations on the natural stone decor which serves as the basis by means of the at least one digital print head.

Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, dass mittels des mindestens einen Druckwalzenwerkes eine oder mehrere Teilflächen der mit dem Dekor zu versehenden Oberfläche bedruckt werden, und dass eine oder mehrere mittels des mindestens einen Druckwalzenwerkes nicht bedruckte Teilflächen mittels des mindestens einen Digitaldruckkopfes bedruckt werden. Diese Ausgestaltung ist insbesondere dann von Vorteil, wenn das mindestens eine Dekorelement, welches mittels des mindestens einen Digitaldruckkopfes aufgedruckt wird, eine relativ große Flächenausdehnung aufweist und eine entsprechende Teilfläche eines zuvor aufgedruckten Dekors verdecken würde. Denn indem die Teilfläche, die nach dem Walzendruck mittels des mindestens einen Digitaldruckkopfes bedruckt wird, zuvor beim Walzendruck ausgelassen wird, lässt sich beim Walzendruck Druckfarbe sparen.A further advantageous embodiment of the method according to the invention is characterized in that by means of the at least one pressure roller mill one or more partial surfaces of the surface to be provided with the decor be printed, and that one or more by means of the at least one printing cylinder unit not printed partial areas are printed by means of the at least one digital printhead. This embodiment is particularly advantageous if the at least one decorative element, which is printed by means of the at least one digital print head, has a relatively large surface area and would conceal a corresponding partial area of a previously printed decoration. Because by the partial area, which is printed after the roller printing by means of the at least one digital printhead, previously omitted in the roller pressure, ink can be saved in the roller printing.

Vorrichtungstechnisch wird diese Ausgestaltung vorzugsweise dadurch realisiert, dass das mindestens eine Druckwalzenwerk mindestens eine Druckwalze, insbesondere Gravurwalze oder Gummituchwalze aufweist, die in ihrer Mantelfläche mindestens eine Ausnehmung zur Erzeugung eines nicht bedruckten Bereichs auf dem plattenförmigen Grundkörper bzw. der Trägerplatte enthält.In terms of apparatus, this embodiment is preferably realized in that the at least one pressure roller unit comprises at least one pressure roller, in particular gravure roller or blanket roller, which contains in its lateral surface at least one recess for producing a non-printed area on the plate-shaped base body or the carrier plate.

Ferner beinhaltet diese Ausgestaltung auch die Möglichkeit, die Reihenfolge von Walzendruck und Digitaldruck zu variieren, d.h. der Walzendruck muss bei dieser Ausgestaltung nicht zwangsläufig vor dem Digitaldruck durchgeführt werden; er kann bei Bedarf auch nach dem Digitaldruck durchgeführt werden. Des Weiteren ermöglicht diese Ausgestaltung eine Anordnung des mindestens einen Digitaldruckkopfes zwischen zwei den Walzendruck ausführenden Druckwalzenwerken.Further, this design also includes the ability to vary the order of roller printing and digital printing, i. the roller pressure does not necessarily have to be performed before the digital printing in this embodiment; If required, it can also be carried out after digital printing. Furthermore, this embodiment enables an arrangement of the at least one digital printhead between two printing roller units which execute the roller printing.

Eine weitere vorteilhafte Ausgestaltung der Erfindung besteht darin, dass mehrere Druckköpfe in Vorschubrichtung des Grundkörpers hintereinander angeordnet werden. Diese Ausgestaltung ermöglicht die Realisierung einer hohen Vorschubgeschwindigkeit des Grundkörpers bei dessen Bedruckung, wobei die Digitaldruckköpfe, die üblicherweise langsamer arbeiten als ein Druckwalzenwerk, jeweils einen Teil des digital aufzudruckenden Dekoreiements aufdrucken. Durch diese Aufgabenteilung, bei der jeder Digitaldruckkopf einen Teil der Digitaldruckarbeit übernimmt, kann die Vorschubgeschwindigkeit des zu bedruckenden Grundkörpers gesteigert werden.A further advantageous embodiment of the invention is that a plurality of print heads in the feed direction of the Basic body are arranged one behind the other. This embodiment makes it possible to realize a high feed rate of the main body during its printing, wherein the digital printheads, which usually work more slowly than a printing roll mill, each imprint a part of the decoreement to be printed digitally. This division of responsibilities, in which each digital print head takes over a part of the digital printing work, the feed rate of the base body to be printed can be increased.

Weitere bevorzugte und vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Further preferred and advantageous embodiments of the invention are specified in the subclaims.

Nachfolgend wird die Erfindung anhand einer mehrere Ausführungsbeispiele darstellenden Zeichnung näher erläutert. Es zeigen in schematischer Darstellung:

another plate-shaped product with a decorative surface, in plan view.

In Fig. 1 ist eine Vorrichtung bzw. Anlage 1 zur Herstellung von plattenförmigen Produkten, beispielsweise von Fußboden-, Wand- oder Deckenpaneelen mit einer ein Dekor aufweisenden Oberfläche dargestellt.In Fig. 1 is a device or system 1 for the production of plate-shaped products, for example, presented by floor, wall or ceiling panels with a decorative surface.

Mehrere plattenförmige Grundkörper 2 sind auf einem Förderband 3 angeordnet, die einzeln der Reihe nach verschiedenen Bearbeitungsstationen 4, 5, 6, 7 und 8 zugeführt werden. Die Transportrichtung der Grundkörper 2 ist in Fig. 1 mit einem Pfeil angedeutet und verläuft von links nach rechts. Anstelle mehrerer einzelner Grundkörper 2 kann auch ein großflächiges Werkstück oder ein endlos hergestelltes Werkstück bearbeitet werden, das nach der im Folgenden beschriebenen Bearbeitung in einzelne Platten (Zuschnitte) zerteilt wird.A plurality of plate-shaped base bodies 2 are arranged on a conveyor belt 3, which are supplied individually in series to different processing stations 4, 5, 6, 7 and 8. The transport direction of the base body 2 is in Fig. 1 indicated by an arrow and runs from left to right. Instead of a plurality of individual base body 2 can also be a large-scale workpiece or an endless manufactured workpiece are processed, which is divided into individual plates (blanks) after the processing described below.

Das Werkstück bzw. die Grundkörper 2 sind aus einer Trägerplatte aus Holzwerkstoff, aus Schichtstoff und/oder aus mindestens einer Compactplatte hergestellt. Compactplatten werden aus harzgetränkten Zellulosebahnen hergestellt, die unter großem Druck und bei hohen Temperaturen in Laminatpressen verpresst werden. Vorzugsweise handelt es sich bei den Grundkörpern 2 jedoch um geschliffene Holzwerkstoffplatten, beispielsweise um Spanplatten, mitteldichte Faserplatten (MDF-Platten), hochdichte Faserplatten (HDF-Platten) oder Hartfaserplatten.The workpiece or the basic body 2 are made of a carrier plate of wood material, of laminate and / or of at least one compact plate. Compact panels are made of resin-impregnated cellulosic sheets, which are pressed under high pressure and at high temperatures in laminate presses. Preferably, however, the base bodies 2 are ground wood-based panels, for example chipboard, medium density fiberboard (MDF), high density fiberboard (HDF) or hardboard.

Nach einer (nicht dargestellten) Bürststation, die etwaige Verunreinigungen oder Schleifstaub entfernt, wird mittels (nicht gezeigter) Auftragswalzen mehrstufig Füller aufgebracht, wobei nach jeder Stufe eine Zwischentrocknung erfolgt. Auf den so vorliegenden Grundkörper 2 wird dann wiederum mehrstufig eine im Grundfarbton eines nachfolgend aufgedruckten Dekors gehaltene Grundierung mittels (nicht gezeigter) Walzen aufgetragen, wobei wieder nach jedem Auftrag eine teilweise Trocknung erfolgt.After a (not shown) brushing station, which removes any impurities or grinding dust, filler is applied by means of (not shown) applicator rollers in several stages, wherein after each stage, an intermediate drying takes place. On the basic body 2 thus present in turn, a primer held in the basic color shade of a subsequently printed decoration is then in turn applied by means of rollers (not shown), partial drying taking place again after each application.

Sodann wird der grundierte plattenförmige Grundkörper 2 geglättet. Dies erfolgt vorzugsweise mittels beheizter, polierter Stahlwalzen (nicht gezeigt), die unter Anpressen gegen den Grundkörper 2 mit einer Umfangsdrehgeschwindigkeit, welche größer oder niedriger als die Vorschubgeschwindigkeit der Grundkörper 2 ist, über die Breite des Grundkörpers 2 betrieben werden. Der so behandelte plattenförmige Grundkörper 2 weist über dessen gesamte Oberseite eine in Farbe, Glanzgrad und Struktur ebene bzw. gleichmäßige Oberfläche auf.Then, the primed plate-shaped base body 2 is smoothed. This is preferably carried out by means of heated, polished steel rollers (not shown), which are pressed against the base body 2 at a peripheral rotational speed which is greater or lower than the feed speed of the base body 2 over the width of the base body 2 operate. The thus treated plate-shaped base body 2 has over its entire upper surface in a color, gloss level and structure even or uniform surface.

Unmittelbar an die (nicht dargestellte) Glättvorrichtung wird mittels zweier Druckwalzenwerke 4.1, 5.1, die jeweils aus einer gravierten Druckwalze (Druckzylinder) 4.11, 5.11 mit Farb- und Feuchtwalzen und einem Gummituchzylinder 4.12, 5.12 mit Gegendruckzylinder (nicht dargestellt) aufgebaut sind, ein Dekor, vorzugsweise ein Holzdekor aufgedruckt. Dieses Druckverfahren wird auch als indirekter Tiefdruck bezeichnet.Immediately to the (not shown) smoothing device is by means of two printing cylinder units 4.1, 5.1, each of an engraved printing roller (printing cylinder) 4.11, 5.11 with inking and dampening rollers and a blanket cylinder 4.12, 5.12 with impression cylinder (not shown) are constructed, a decor , preferably a wood decor printed. This printing process is also referred to as indirect gravure printing.

Den Druckwalzenwerken 4.1, 5.1 sind Nachbearbeitungsvorrichtungen 4.2, 5.2 nachgeordnet. Die jeweilige Nachbearbeitungsvorrichtung 4.2, 5.2 kann beispielsweise mittels eines Warmluftstroms oder mittels einer elektromagnetischen Strahlung, insbesondere UV-Strahlung eine Trocknung bzw. Teiltrocknung der aufgedruckten Farbe bewirken.The printing cylinder units 4.1, 5.1 are post-processing devices 4.2, 5.2 arranged downstream. The respective post-processing device 4.2, 5.2 can, for example, by means of a hot air flow or by means of electromagnetic radiation, in particular UV radiation cause drying or partial drying of the printed color.

Anstelle von zwei oder mehreren Druckwalzenwerken 4.1, 5.1 kann die erfindungsgemäße Vorrichtung bzw. Anlage 1 gegebenenfalls auch nur ein einzelnes Druckwalzenwerk 4.1 oder 5.1 aufweisen.Instead of two or more printing cylinder units 4.1, 5.1, the device or system 1 according to the invention may optionally also have only a single printing cylinder unit 4.1 or 5.1.

Erfindungsgemäß wird auf einen oder mehrere Teilbereiche des plattenförmigen Grundkörpers 2 mittels mindestens eines Digitaldruckkopfes 6.1 mindestens ein Dekorelement gedruckt, so dass das zuvor aufgedruckte Dekor zumindest teilweise sichtbar bleibt oder das zuvor aufgedruckte Dekor das Dekorelement umgibt.According to the invention, at least one decorative element is printed on one or more partial areas of the plate-shaped main body 2 by means of at least one digital print head 6.1, so that the previously printed decor remains at least partially visible or the previously printed decor surrounds the decorative element.

Der Digitaldruckkopf 6.1 arbeitet beispielsweise nach dem Prinzip der Strahldrucktechnik, die bei so genannten Tintenstrahldruckern weit verbreitet ist. In Fig. 1 ist unterhalb der digitalen Auftragsvorrichtung 6.1 ein kurzer Strich eingezeichnet, der einen Tröpfchenstrahl oder mehrere in Reihe positionierte Tröpfchenstrahlen andeutet. Die digitale Auftragsvorrichtung 6.1 ist derart ausgebildet, dass sie quer zur Bewegungsrichtung des Grundkörpers 2 stellenweise oder zeilenweise ein oder mehrere Dekorelemente auf den Grundkörper aufdruckt. Dieser Digitaldruck druckt somit nicht vollflächig, sondern lediglich partiell.The digital printhead 6.1 operates, for example, on the principle of the jet printing technology, which is widely used in so-called inkjet printers. In Fig. 1 below the digital applicator 6.1, a short line is drawn indicating a droplet jet or a plurality of droplets positioned in series. The digital application device 6.1 is designed in such a way that it prints one or more decorative elements on the base body in places or in rows transversely to the direction of movement of the base body 2. This digital printing does not print completely, but only partially.

Mit dem Digitaldruckkopf 6.1 kann einfarbig oder mehrfarbig gedruckt werden. Beispielsweise kann der Digitaldruckkopf 6.1 mit einer Farbpatrone ausgestattet sein, die eine einzelne Farbe oder farbige Tinte enthält. Alternativ oder zusätzlich kann der Digitaldruckkopf 6.1 aber auch mit einer oder mehreren Farbpatronen versehen sein, die mehrere Kammern mit verschiedenen Tinten bzw. Farben aufweisen bzw. bilden, beispielsweise die Farben gelb, blau und rot als Grundfarben enthalten, so dass der Digitaldruckkopf 6.1 in einem Pass auch mehrere bzw. verschiedene Farben gleichzeitig drucken kann.With the digital print head 6.1 can be printed in one color or multi-color. For example, the digital printhead 6.1 may be equipped with a color cartridge containing a single color or colored ink. Alternatively or additionally, however, the digital print head 6.1 can also be provided with one or more color cartridges that comprise or form a plurality of chambers with different inks or colors, for example containing the colors yellow, blue and red as primary colors, so that the digital print head 6.1 in one Pass also several or different colors can print at the same time.

Bei den Dekorelementen handelt es sich beispielsweise um Abbildungen von Ästen (d.h. Astquerschnitten), Einschlüssen, Verwachsungen, Maserungsfehlern, Maserknollen, Jahresringen, Darstellungen von hellem Splintholz, Fraßgängen (z.B. Holzwurmlöchern/-gängen), Nagel- und/oder Schraubenköpfen, etc..The decorative elements are, for example, images of branches (ie branch cross-sections), inclusions, adhesions, grain defects, grain tufts, annual rings, representations of light sapwood, feeding passages (eg woodworm holes / holes), nail and / or screw heads, etc.

Des Weiteren oder alternativ kann es sich bei den Dekorelementen auch um Einschlüsse oder sonstige markante Stellen von Stein- oder Fantasiedekoren handeln.Furthermore, or alternatively, the decorative elements may also be inclusions or other distinctive locations of stone or fantasy decors.

Unter dem Begriff "Dekorelement" können im vorliegenden Kontext auch Logos verstanden werden. Bei den Logos handelt es sich beispielsweise um Firmennamen, Wort-Bildmarken, Slogans, Aufdrucken, wie sie auf Frachtkisten üblich sind, etc..The term "decorative element" in the present context, logos are understood. The logos are, for example, company names, word markers, slogans, imprints, as they are customary on cargo boxes, etc.

Ferner ist ein Computer 6.2 als Mittel zum Erzeugen einer Punkteverteilung zur Ansteuerung der digitalen Auftragsvorrichtung 6.1 mit derselben verbunden. Der Computer 6.2 bereitet digitale Ansteuerinformationen auf und überträgt diese auf den Digitaldruckkopf 6.1.Furthermore, a computer 6.2 as means for generating a dot distribution for driving the digital application device 6.1 is connected to the same. The computer 6.2 processes digital control information and transmits it to the digital printhead 6.1.

Die Bilddaten verschiedener Varianten der genannten Dekorelemente und/oder Logos sind in einem Datenspeicher 6.3 des Computers 6.2 hinterlegt. Des Weiteren ist der Computer 6.2 mit einem Zufallsgenerator 6.4 versehen. Der Zufallsgenerator 6.4 dient dazu, verschiedene Varianten eines oder mehrerer Dekorelemente, z.B. Äste sowie helle Splintholzanteile, nach einem Zufallsprinzip auszuwählen sowie die Position des jeweiligen Dekorelements auf der Trägerplatte 2 in X- und/oder Y-Richtung ebenfalls nach einem Zufallsprinzip vorzugeben.The image data of different variants of said decorative elements and / or logos are stored in a data memory 6.3 of the computer 6.2. Furthermore, the computer 6.2 is provided with a random number generator 6.4. The random number generator 6.4 is used to different variants of one or more decorative elements, e.g. Branches and bright sapwood parts to select at random and to specify the position of the respective decorative element on the support plate 2 in the X and / or Y direction also according to a random principle.

Es liegt ferner im Rahmen der Erfindung, dass der Computer nicht nur nach einem Zufallsprinzip ein Dekorelement aus einer Vielzahl von Dekorelementen auswählen kann, sondern ein Dekorelement auch abwandeln, insbesondere verfremden kann. So kann beispielsweise die Form eines ellipsenförmigen Dekorelements durch Variieren der Länge der Haupt- und/oder Nebenachse der Ellipse abgewandelt werden. Des Weiteren umfasst die Erfindung auch eine Ausgestaltung, bei welcher der Computer nach einem Zufallsprinzip Dekorelemente sogar erzeugen kann, beispielsweise geometrische Formen wie einen Kreis, ein Quadrat, Dreiecke, Trapeze, Polygone, oder Linien oder gar komplexe Dekorelemente.It is also within the scope of the invention that the computer can not only randomly select a decorative element from a variety of decorative elements, but also modify a decorative element, in particular can alienate. For example, the shape of an elliptical decorative element by varying the length of the main and / or Subordinate axis of the ellipse to be modified. Furthermore, the invention also includes an embodiment in which the computer can even produce decorative elements according to a random principle, for example geometric shapes such as a circle, a square, triangles, trapezoids, polygons, or lines or even complex decorative elements.

An die digitale Auftragsvorrichtung 6.1 schließt sich wie zuvor auch an die Walzendruckwerke 4.1, 5.1 eine Nachbearbeitungsvorrichtung 6.5 an, um das oder die zuvor aufgebrachten Dekorelemente zu trocknen.To the digital application device 6.1 is followed as before to the roller printing units 4.1, 5.1, a post-processing device 6.5 to dry the or the previously applied decorative elements.

Auf die digitale Auftragsvorrichtung 6.1 bzw. die Nachbearbeitungsvorrichtung 6.5 folgen Bearbeitungsstationen 7, 8, mittels denen auf das Dekor einschließlich der aufgedruckten Dekorelemente eine Versiegelungsschicht (Verschleißschutzschicht) aufgebracht wird.Processing stations 7, 8, by means of which a sealing layer (wear protection layer) is applied to the decor, including the printed decorative elements, follow the digital application device 6.1 or the post-processing device 6.

Als Versiegelung des Dekors wird eine mit UV-Strahlung härtbare, transparente Lackbeschichtung in mindestens zwei Stufen aufgebracht. Der Versiegelungslack enthält Korundpartikel und/oder andere die Abriebfestigkeit erhöhende Partikel. Handelt es sich bei den herzustellenden dekorativen Grundkörpern bzw. Platten 2 um solche, die keiner hohen Abriebbeanspruchung ausgesetzt werden, beispielsweise um Möbelteile, insbesondere um Rückwände für Schränke, so kann der Versiegelungslack auch frei von Korundpartikeln oder sonstigen die Abriebfestigkeit erhöhenden Partikel sein.As a seal of the decoration, a UV-curable, transparent lacquer coating is applied in at least two stages. The sealing lacquer contains corundum particles and / or other abrasion resistance-increasing particles. If the decorative base bodies or plates 2 to be produced are those which are not subjected to high abrasion stress, for example furniture parts, in particular rear panels for cabinets, then the sealing lacquer may also be free of corundum particles or other particles which increase the abrasion resistance.

In der Bearbeitungsstation 7 wird eine im Wesentlichen vollflächige Beschichtung aus einem UV-härtbaren, transparenten Versiegelungslack aufgebracht. Hierzu weist die Bearbeitungsstation 7 eine Auftragswalze 7.1 auf, die eine gleichmäßige Schicht aus Lack auf die Oberseite der Grundkörper 2 aufbringt. In der nachgeschalteten Nachbearbeitungsvorrichtung 7.2 wird die aufgebrachte Beschichtung zumindest teilweise getrocknet und ausgehärtet.In the processing station 7, a substantially full-surface coating of a UV-curable, transparent sealing lacquer is applied. For this purpose, the Processing station 7 on an applicator roller 7.1, which applies a uniform layer of paint on the top of the base body 2. In the downstream post-processing device 7.2, the applied coating is at least partially dried and cured.

In der Bearbeitungsstation 8 wird wiederum mittels einer Auftragswalze 8.1 eine Beschichtung aus einem UV-härtbaren, transparenten Versiegelungslack direkt aufgetragen, wobei hier die Auftragsmenge bezogen auf die Plattenoberfläche variiert. Dadurch kommt es zu einer möglicherweise beabsichtigten dreidimensionalen Strukturierung der oberen Lackschicht.In the processing station 8, in turn, a coating of a UV-curable, transparent sealing lacquer is applied directly by means of an applicator roller 8.1, in which case the application quantity varies with respect to the surface of the plate. This leads to a possibly intended three-dimensional structuring of the upper lacquer layer.

Mittels der auf die Auftragswalze 8.1 folgenden Nachbearbeitungsvorrichtung wird dann die zuletzt aufgebrachte Beschichtung zumindest teilweise ausgehärtet, damit die dreidimensionale Strukturierung fixiert wird, bevor sich diese aufgrund eines Zerfließens aufhebt.By means of the following on the applicator roll 8.1 post-processing device then the last applied coating is at least partially cured, so that the three-dimensional structuring is fixed before it cancels due to bleeding.

Mit den Walzendruckwerken 4.1, 5.1 kann zunächst die gesamte Oberseite des plattenförmigen Grundkörpers 2 mit einem Dekor, beispielsweise Holz- oder Steindekor versehen werden, worauf dann mit dem mindestens einen Digitaldrucker 6.1 ein oder mehrere einzelne Oberflächenbereiche des jeweiligen Grundkörpers 2 zusätzlich bedruckt werden.With the roller printing units 4.1, 5.1, the entire upper side of the plate-shaped basic body 2 can first be provided with a decoration, for example wood or stone decor, whereupon one or more individual surface areas of the respective basic body 2 are additionally printed with the at least one digital printer 6.1.

Alternativ oder ergänzend sieht die Erfindung vor, dass mit dem Walzendruckverfahren nur ein bestimmter Oberflächenbereich des jeweiligen Grundkörpers 2 bedruckt wird und dass der oder die dabei nicht bedruckten Bereiche mittels mindestens eines Digitaldruckers 6.1 bedruckt werden. Diese Ausgestaltung ist in Fig. 2 skizziert. Dort ist zu erkennen, dass ein Druckwalzenwerk mindestens eine Druckwalze, insbesondere Gummituchwalze 5.12 aufweist, die in ihrer Mantelfläche mindestens eine Ausnehmung 5.13 zur Erzeugung eines nicht bedruckten Bereichs 2.1 auf dem plattenförmigen Grundkörper 2 enthält. Der Druckwalze 5.12 ist ein Digitaldrucker 6.1 nachgeordnet, der an einer einen Zufallsgenerator 6.4 aufweisenden Steuerung 6.2 angeschlossen ist, wobei die Steuerung ein in den Plattenbereich 2.1 zu druckendes Dekorelement aus einer Gruppe von Dekorelementen nach einem Zufallsprinzip ausgewählt oder erzeugt.Alternatively or additionally, the invention provides that with the roller printing method only a certain surface area of the respective base body 2 is printed and that the one or the non-printed areas are printed by at least one digital printer 6.1. These Design is in Fig. 2 outlined. There, it can be seen that a printing drum unit has at least one pressure roller, in particular blanket roller 5.12, which contains in its lateral surface at least one recess 5.13 for producing a non-printed area 2.1 on the plate-shaped basic body 2. The pressure roller 5.12 is followed by a digital printer 6.1, which is connected to a controller 6.2 having a random number generator 6.2, wherein the controller selects or generates a decorative element to be printed in the plate area 2.1 from a group of decorative elements according to a random principle.

Mit einem Druckwalzenwerk 5.1 der in Fig. 2 skizzierten Art können in Kombination mit einem Digitaldrucker 6.1 beispielsweise Fantasiedekore mit einem Stein- oder Fliesenmuster erstellt werden, bei denen ein durch die Druckwalze 5.12 erzeugtes Basisdekor durch Dekorfliesen, Ornamente, Intarsienbilder, Logos, etc., die in die zunächst nicht bedruckten Bereiche 2.1 mittels des Digitaldruckes gedruckt werden, ergänzt bzw. vervollständigt werden.With a printing cylinder 5.1 of the in Fig. 2 Outlined Art can be created in combination with a digital printer 6.1, for example, Fantasy decors with a stone or tile pattern in which a generated by the pressure roller 5.12 base decor by decorative tiles, ornaments, marquetry, logos, etc., in the initially unprinted areas 2.1 means printed, completed or completed.

Bei regelmäßigen Dekoren, wie zum Beispiel einem Bild einer Kieselsteinfläche, Kaffeebohnenschüttung, etc., kann mit einer Vorrichtung gemäß Fig. 2 das Dekor variiert werden, indem die ansonsten regelmäßige Ornamentanordnung auf der Druckwalze (Gravurwalze oder Gummituchzylinder 5.12) bewusst mit Ausnehmungen (bzw. gravurfreien Zonen) 5.13 versehen wird, wobei in die durch diese gravurfreien Zonen erzeugten Bereiche 2.1 des plattenförmigen Grundkörpers 2 hinein modifizierte Ornamente mit dem Digitaldrucker 6.1 gedruckt werden, zum Beispiel in einer unterschiedlichen Farbe oder in einer anderen Ausrichtung oder verzerrt usw..For regular decors, such as a picture of a pebble surface, coffee bean bed, etc., can with a device according to Fig. 2 The decor can be varied by the otherwise regular ornament arrangement on the platen roller (gravure roller or blanket cylinder 5.12) is deliberately provided with recesses (or engraving zones) 5.13, wherein in the generated by these engraving zones 2.1 areas of the plate-shaped base body 2 into modified ornaments be printed to the digital printer 6.1, for example, in a different color or in a different orientation or distorted, etc.

In Fig. 3 ist ein Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung dargestellt, wobei mindestens ein Digitaldruckkopf 6.1 einer Gummituchwalze 5.12 eines Druckwalzenwerks 5.1 zugeordnet ist. Der Digitaldrucker 6.1 druckt dabei auf die Gummituchwalze 5.12, die das mittels des Digitaldruckkopfes 6.1 aufgebracht Dekorelement auf den zu bedruckenden Grundkörper 2 überträgt. Das so aufgebrachte Dekor wird mittels der nachgeordneten Nachbearbeitungsvorrichtung 6.5 zumindest teilweise getrocknet.In Fig. 3 an embodiment of a device according to the invention is shown, wherein at least one digital print head 6.1 a blanket roller 5.12 of a printing cylinder plant 5.1 is assigned. The digital printer 6.1 prints on the blanket roller 5.12, which transfers the applied by means of the digital print head 6.1 decorative element on the base body 2 to be printed. The decor thus applied is at least partially dried by means of the downstream finishing device 6.5.

Mit einer Vorrichtung 1 gemäß Fig. 1 ist es insbesondere möglich, ein Dekor als mehrfarbiges Dekor zu drucken, wobei mit jedem der Druckwalzenwerke 4.1, 5.1 eine andere Farbe des Dekors auf den Grundkörper 2 gedruckt wird, und wobei eine Farbe des mehrfarbigen Dekors mittels der den mindestens einen digitalen Druckkopf 6.1 aufweisenden digitalen Druckstation 6 auf den Grundkörper 2 gedruckt wird. So können beispielsweise ohne einen Druckwalzenwechsel verschiedene Holzdekore (Holzarten) gedruckt werden, jedenfalls solange sich die Holzarten in ihrer typischen Grundstruktur (Maserung) nicht zu stark unterscheiden. Das spart erhebliche Rüstzeiten, wobei der erforderliche Farbwechsel alleine vergleichsweise einfach und schnell durchgeführt werden kann.With a device 1 according to Fig. 1 In particular, it is possible to print a decor as a multicolored decor, with each of the printing cylinder units 4.1, 5.1 a different color of the decor is printed on the base body 2, and wherein a color of the multicolored decoration by means of the at least one digital printhead having 6.1 digital Printing station 6 is printed on the base body 2. Thus, for example, without a pressure roller change various wood designs (types of wood) can be printed, at least as long as the wood species in their typical basic structure (grain) are not too different. This saves considerable set-up times, whereby the required color change alone can be carried out comparatively easily and quickly.
