Die Erfindung betrifft einerseits ein Verfahren zum Erzeugen eines gedruckten Oberflächendekors auf einem Paneel als Bestandteil eines Boden-, Wand- oder Deckenbelags gemäß den Merkmalen im Oberbegriff des Anspruchs 1.On the one hand, the invention relates to a method for producing a printed surface decoration on a panel as part of a floor, wall or ceiling covering according to the features in the preamble of claim 1.

Andererseits richtet sich die Erfindung auf eine Druckmaschine zur Durchführung des Verfahrens entsprechend den Merkmalen im Oberbegriff des Anspruchs 4.On the other hand, the invention is directed to a printing machine for carrying out the method according to the features in the preamble of claim 4.

Die DE 195 32 819 A1 beschreibt einleitend zunächst ein Verfahren zur Herstellung einer Holzwerkstoffplatte mit einer optisch gestaltbaren Oberfläche anhand von hochdichten Faserplatten, die unter Druck aus Holzfasern und Additiven hergestellt werden. Diese Faserplatten werden an den Oberflächen mit Papier versehen, welches mit dem gewünschten Dekor bedruckt ist. Anschließend werden diese Faserplatten versiegelt. Die Fertigung derartiger Faserplatten kann im Taktverfahren oder auch im Durchlaufprozess erfolgen.The DE 195 32 819 A1 describes initially a method for producing a wood-based panel with an optically shapable surface using high-density fiberboard, which are made under pressure from wood fibers and additives. These fibreboards are provided on the surfaces with paper, which is printed with the desired decor. Then these fiberboard are sealed. The production of such fiberboard can be done in the cycle or in the continuous process.

Um pro Zeiteinheit die Anzahl an mit einem Oberflächendekor versehenen Faserplatten zu erhöhen, wird anschließend in der DE 195 32 819 A1 ein Verfahren erläutert, gemäß welchem keine bedruckten Papiere mehr auf die Faserplatten aufgebracht, sondern die Faserplatten direkt für einen Druck vorbereitet und dann in einer Druckmaschine mit einem Oberflächendekor versehen werden.In order to increase the number of fiberboards provided with a surface finish per unit of time, is subsequently in the DE 195 32 819 A1 explains a method according to which no printed papers are applied to the fiberboard more, but the fibreboard prepared directly for printing and then provided in a printing machine with a Oberflächendekor.

Auch die DE 20 2004 018 194 U1 befasst sich mit dem Direktdruck von Großformatplatten aus einem Holzwerkstoff in einer Druckmaschine. Es wird in dieser Druckschrift erläutert, dass die Druckmaschine so angesteuert werden muss, dass die vordere Plattenkante einer Großformatplatte immer am selben Punkt in die Druckmaschine einläuft, um einen Versatz des Druckbilds zu vermeiden. Hierzu wird die einlaufende Großformatplatte an einer Festkante geführt, damit eine Bezugskante für die Weiterverarbeitung vorhanden ist.Also the DE 20 2004 018 194 U1 deals with the direct printing of large format plates made of a wood material in a printing machine. It is explained in this document that the printing press must be controlled so that the front plate edge of a large format plate always runs at the same point in the press to avoid misalignment of the printed image. For this purpose, the incoming large format plate is guided on a fixed edge, so that a reference edge for further processing is available.

In der DE 10 2004 011 229 A1 wird eine Vorrichtung und ein Verfahren zum Bedrucken von Platten beschrieben, bei welchem die Platten in Vorschubrichtung bewegt und mit einer ersten Auftragswalze mit einem Referenzdruckbild bedruckt wird. Anschließend wird die Länge des ganzen Referenzdruckbildes oder eines Teils davon gemessen und der Anpressdruck der mindestens einen nachfolgenden Auftragswalze und/oder eine Relativbewegung zwischen Platte und Auftragswalze und/oder der Auftragswalze und der Gravurwalze, basierend auf der gemessenen Länge, zur Erzeugung eines Druckbildes in einer gewünschten Länge gesteuert. Zur Erzeugung eines exakten Druckbildes wird dabei die Höhe der Auftragswalze und/oder einer Gegendruckwalze entsprechend verändert. Mit diesem Verfahren kann eine hohe Druckgenauigkeit erreicht werden.In the DE 10 2004 011 229 A1 An apparatus and a method for printing on plates is described in which the plates are moved in the feed direction and printed with a first application roller with a reference print image. Subsequently, the length of the entire reference print image or a part thereof is measured and the contact pressure of the at least one subsequent applicator roll and / or a relative movement between the plate and the applicator roll and / or the applicator roll and the gravure roll, based on the measured length, to produce a printed image in one desired length controlled. To generate an exact print image while the height of the applicator roll and / or a counter-pressure roller is changed accordingly. With this method, a high printing accuracy can be achieved.

Gegenstand der DE 103 33 626 A1 ist eine Vorrichtung zum Bedrucken von flächigen Werkstücken. In Transportrichtung des Werkstücks gesehen ist vor dem Druckspalt eine Detektionseinrichtung zur Lageerkennung einer Werkstückvorderkante oder einer Bildanfangsmarke vorhanden, wobei diese derart mit der Transporteinrichtung und/oder einem Druckzylinder zusammenwirkend ausgebildet ist, dass der Transport des Werkstücks noch vor dem Erreichen des Druckspalts beschleunigt oder verzögert und/oder die Winkellage des Druckzylinders durch Beschleunigen oder Verzögern der Rotationsbewegung verändert werden kann, um den Anfang des Druckbildes mit der Werkstückvorderkante oder der vorgesehenen Rapportlage in Übereinstimmung zu bringen. Auch bei dieser Vorrichtung soll das Druckbild genauer positioniert werden.Subject of the DE 103 33 626 A1 is a device for printing on flat workpieces. As seen in the transport direction of the workpiece, a detection device for detecting the position of a workpiece leading edge or a starting image mark is present in front of the printing nip, with the latter thus being provided with the transport device and / or a printing cylinder is formed cooperatively, that the transport of the workpiece accelerated or decelerated before reaching the nip and / or the angular position of the printing cylinder by accelerating or decelerating the rotational movement can be changed to the beginning of the printed image with the workpiece front edge or the intended repeat position in accordance bring. Also in this device, the print image is to be positioned more accurately.

Eine Holzfaserplatte, insbesondere ein Fußbodenpaneel, wird in der DE 102 52 863 A1 beschrieben. Es soll eine HDF-Trägerplatte mit einer Oberseite und einer Unterseite verwendet werden, wobei die Oberseite ein Dekor aufweist, vorzugsweise ein Holz- oder Fliesendekor. Das Dekor wird direkt auf die Oberseite der Trägerplatte aufgedruckt und mit mindestens einer Schicht aus einem transparenten Kunstharz abgedeckt. Aus der Holzfaserplatte können anschließend Fußbodenpaneele gesägt werden.A wood fiber board, in particular a floor panel, is used in the DE 102 52 863 A1 described. It is an HDF support plate are used with a top and a bottom, the top has a decor, preferably a wood or tile decor. The decor is printed directly on the top of the carrier plate and covered with at least one layer of a transparent synthetic resin. From the wood fiber board floor panels can be sawed.

Gegenstand der EP 1 541 373 A2 ist ein Verfahren zur Herstellung von Paneelen mit dekorativen Oberflächen, wobei die Oberflächen mit unterschiedlichen Dekoren bedruckt werden. Jeder Dekorabschnitt besitzt ein Anfang und ein Ende, wobei das Ende eines Dekorabschnitts zum Anfang des darauf folgenden Dekorabschnitts passt. Dadurch wird der Eindruck eines kontinuierlich durchlaufenden Dekors geschaffen.Subject of the EP 1 541 373 A2 is a process for the production of panels with decorative surfaces, whereby the surfaces are printed with different decors. Each decorative section has a beginning and an end, with the end of a decorative section matching the beginning of the subsequent decorative section. This creates the impression of a continuous continuous decoration.

Obwohl sich der Direktdruck von Großformatplatten aus einem Holzwerkstoff bewährt hat, haftet ihm jedoch die Eigenart an, dass die aus einer Druckmaschine tretenden Großformatplatten einen vergleichsweise uniformen Oberflächencharakter aufweisen. Somit kann man aus einer Großformatplatte immer nur eine bestimmte Anzahl von Paneelen abtrennen, deren Oberflächendekors sich dann von Großformatplatte zu Großformatplatte wiederholen. Die abgetrennten Paneele unterscheiden sich lediglich geringfügig voneinander.Although the direct printing of large format boards made of a wood-based material has proved successful, however, it adheres to the peculiarity that the large format plates emerging from a printing press have a comparatively uniform surface character. Thus, one can only ever separate a certain number of panels from a large format plate whose surface decors repeat from large format plate to large format plate. The separated panels differ only slightly from each other.

Aus der GB 1 260 250 A ist ein Verfahren und eine Vorrichtung zur Herstellung von sich unregelmäßig wiederholenden Mustern auf Oberflächen bekannt. Es wird vorgeschlagen die Relativgeschwindigkeit zwischen einer Druckwalze und der zu bedruckenden Platte zu variieren um das Druckbild zu stauchen oder zu dehnen. Dieses Verfahren führt zwangsläufig zu erhöhtem Verschleiß an der Druckwalze, was als nachteilig angesehen wird.From the GB 1 260 250 A For example, a method and apparatus for producing irregularly repeating patterns on surfaces is known. It is proposed the relative speed between a pressure roller and to vary the plate to be printed to compress or stretch the printed image. This method inevitably leads to increased wear on the pressure roller, which is considered disadvantageous.

Der Erfindung liegt - ausgehend vom Stand der Technik - die Aufgabe zugrunde, ein Verfahren zum Erzeugen von gedruckten Oberflächendekors auf Paneelen als Bestandteile von Boden-, Wand- oder Deckenbelägen sowie eine Druckmaschine zur Durchführung des Verfahrens zu schaffen, die eine größere Vielfalt der letztlich auf den einzelnen Paneelen vorhandenen Oberflächendekors gewährleisten.The invention is - based on the prior art - the object of the invention to provide a method for producing printed surface decor on panels as components of floor, wall or ceiling coverings and a printing machine for performing the method, which has a greater variety of ultimately To ensure the individual panels existing surface decor.

Die Lösung des verfahrensmäßigen Teils dieser Aufgabe wird in den im Anspruch 1 angegebenen Merkmalen gesehen.The solution of the procedural part of this task is seen in the features specified in claim 1.

Kerngedanke der Erfindung bildet eine gezielte variable Zuführung der Großformatplatten zur Druckmaschine. Da die Druckwalze in der Druckmaschine axial unverschiebbar gelagert ist, wird nunmehr jede neue Großformatplatte bezüglich der voraufgehend in der Druckmaschine befindlichen Großformatplatte in Längsrichtung mit Abstand und/oder in Querrichtung um ein bestimmtes Maß versetzt in die Druckmaschine eingeführt.Core idea of the invention is a targeted variable supply of large format plates to the printing press. Since the pressure roller is mounted axially immovable in the printing press, each new large format plate is now introduced with respect to the upstream in the printing press large format plate in the longitudinal direction at a distance and / or transversely offset by a certain amount in the printing press.

So ist es beispielsweise denkbar, dass eine erste Großformatplatte mit ihrer linken Längsseite an einem ersten Anschlag, die folgende Großformatplatte mit ihrer rechten Längsseite an einem zweiten Anschlag und eine dritte Großformatplatte in einer Position zwischen diesen beiden jeweils verstellbaren Anschlägen durch die Druckmaschine geführt werden. Durch die Querversetzung passieren die Großformatplatten die Druckwalze in unterschiedlichen Längenbereichen. Dieser Sachverhalt macht sich dann nach dem meistens im Durchlaufprozess erfolgenden Auftrennen der Großformatplatten in Paneele und deren anschließenden randseitigen Nut/Feder-Profilierung in einer größeren Anzahl unterschiedlicher Oberflächendekors auf den Paneelen bemerkbar. Die Attraktivität eines Bodens, einer Wand oder einer Decke, welche aus solchen Paneelen gestaltet sind, kann auf diese Weise deutlich erhöht werden.For example, it is conceivable that a first large format plate with its left longitudinal side on a first stop, the following large format plate with its right longitudinal side on a second stop and a third large format plate in a position between these two adjustable stops are guided by the printing press. Due to the transverse offset, the large format plates pass the pressure roller in different lengths. This situation then becomes apparent after the separation of the large format panels in panels, which usually takes place in the continuous process, and their subsequent marginal groove / tongue profiling in a larger number of different surface decors on the panels. The attractiveness of a floor, a wall or a ceiling, which are designed from such panels can be significantly increased in this way.

Die in die Druckmaschine einlaufenden Großformatplatten können statt der Querversetzung aber auch in Längsrichtung mit Abstand zueinander versetzt werden. Hierdurch erhalten die Großformatplatten in der Druckmaschine wiederum andere Oberflächendekors mit der Folge, dass die Vielfalt der Oberflächendekors auf den letztlich abgetrennten Paneelen nochmals erhöht wird.The incoming large format plates in the printing machine can be offset from each other but also in the longitudinal direction at a distance from each other. As a result, the large format plates in the printing press, in turn, receive other surface decorations, with the result that the diversity of the surface decorations on the panels that have ultimately been removed is increased again.

Eine weitere Möglichkeit zur Erhöhung der Dekorvielfalt besteht darin, die Großformatplatten sowohl in Längsrichtung mit Abstand zueinander als auch in Querrichtung versetzt durch die Druckmaschine zu führen.Another way to increase the variety of decor is to guide the large format plates both longitudinally spaced from each other and offset in the transverse direction by the printing press.

Das Versetzen in Längsrichtung und/oder Querrichtung erfolgt definiert, das heißt gesteuert und nicht zufällig. Es wird zuvor festgelegt, welches Druckbild die einzelnen Paneele aufweisen sollen. Die Größe des Versatzes in Längs- oder Querrichtung wird manuell festgelegt, wobei durchaus vorstellbar ist, dass mit Hilfe eines Computerprogramms eine größere Anzahl von Datensätzen generiert wird, wobei jeder Datensatz einen Wert für den Längsversatz und den Querversatz enthält und wobei diese Daten zur Steuerung der Anlage verwendet werden. Durch Verwendung dieser Datensätze kann sichergestellt werden, dass sich ein Dekor nicht identisch wiederholt. Durch entsprechende Parametrisierung des mathematischen Modells ist es sogar möglich, einen entsprechenden Grad der Abweichung festzulegen, um zu gewährleisten, dass der seitliche oder in Längsrichtung vorgesehene Versatz eine bestimmte Mindestgröße hat, um sehr ähnliche Dekore zu vermeiden.The offset in the longitudinal direction and / or transverse direction is defined, that is controlled and not random. It is previously determined which print image the individual panels should have. The size of the offset in the longitudinal or transverse direction is set manually, although it is quite conceivable that using a computer program, a larger number of records is generated, each record contains a value for the longitudinal offset and the lateral offset and this data to control the Plant to be used. Using these records can ensure that a decor does not repeat identically. By appropriate parameterization of the mathematical model, it is even possible to set a corresponding degree of deviation to ensure that the lateral or longitudinal offset provided has a certain minimum size to avoid very similar decorations.

Das erfindungsgemäße Verfahren kann bei zu bedruckenden Platten jeglicher Art angewandt werden, z.B. bei Platten aus einem verdichteten Fasermaterial oder aus Kunststoff.The method according to the invention can be applied to plates of any kind to be printed, e.g. in the case of plates of a compacted fiber material or of plastic.

Eine vorteilhafte Ausführungsform des Verfahrens besteht nach der Erfindung bei einem so genannten Mehrstabdruck gemäß den Merkmalen des Anspruchs 2 darin, dass die unmittelbar ohne Abstand oder im Abstand zueinander in die Druckmaschine eingeführten Großformatplatten um jeweils die Breite mindestens eines Stabs quer versetzt werden. Auch hierdurch kann die Vielfalt der Oberflächendekors nochmals heraufgesetzt werden.An advantageous embodiment of the method according to the invention in a so-called multi-bar pressure according to the features of claim 2 is that the immediately introduced without spacing or at a distance from each other in the printing machine large format plates are offset transversely by the width of at least one rod. This also allows the diversity of Oberflächendekors be increased again.

Es besteht hinsichtlich des Druckbilds keine Beschränkung auf ein Einstab- oder beliebiges Mehrstabdekor. Grundsätzlich ist es möglich, auf diese Art und Weise jede fotorealistische Abbildung einer Oberfläche zu erzeugen, die ihren realistischen Eindruck erst durch die Variabilität der einzelnen Dekore gewinnt. Dies ist typischerweise bei Holzdekoren der Fall. Grundsätzlich kann aber auch der Gesamteindruck beispielsweise eines Korkboden-Dekors oder eines Holzboden-Dekors verbessert werden, wenn die einzelnen Platten nicht alle das gleiche Druckbild aufweisen, sondern voneinander abweichen. Besonders wenn die Dekore sehr prägnant sind, wie bei rustikalen, stark gemaserten und/oder gealterten Holzdekoren, ist es wichtig, Wiederholungen im Erscheinungsbild des gedruckten Bodens zu vermeiden.There is no restriction on a single-rod or any multi-bar decor with regard to the printed image. In principle, it is possible to produce in this way any photorealistic image of a surface that gains its realistic impression only through the variability of the individual decors. This is typically the case with wood decors. Basically, however, the overall impression of, for example, a cork floor decor or a wooden floor decor can be improved if the individual plates do not all have the same print image, but differ from each other. Especially when the decors are very concise, as in rustic, heavily grained and / or aged wood decors, it is important to avoid repetition in the appearance of the printed floor.

Die Dekorvielfalt auf den letztlich fertig gestellten Paneelen kann ferner dadurch noch attraktiver gestaltet werden, dass entsprechend Anspruch 3 in freier Auswahl z.B. jede zweite, dritte oder auch vierte bedruckte Großformatplatte vor dem Auftrennen in Paneele in ihrer horizontalen Ebene um 180° gedreht wird, so dass die Nut/Feder-Profilierung bei einem Teil der Paneele umgekehrt herausgearbeitet wird.The variety of decor on the ultimately finished panels can also be made even more attractive that according to claim 3 in free choice, for example. every second, third or even fourth printed large format plate is rotated by 180 ° in its horizontal plane prior to separation into panels, so that the groove / tongue profiling is worked out in reverse at a part of the panels.

Die Lösung des gegenständlichen Teils der Aufgabe kennzeichnet sich nach Anspruch 4 dadurch, dass quer verstellbare und fixierbare Anschläge für die Großformatplatten vorgesehen sind.The solution of the objective part of the task is characterized according to claim 4, characterized in that transversely adjustable and fixable stops are provided for the large format plates.

Des Weiteren ist es in diesem Zusammenhang denkbar, auch den Abstand voneinander in die Druckmaschine eingeführter Großformatplatten - ggf. variierbar - zu programmieren. Dies kann ergänzend zu den verstellbaren Anschlägen oder gesondert von diesen erfolgen. Die Variation des Abstands in Längsrichtung kann auch als zeitversetztes Einführen der Großformatplatten in die Druckmaschine ausgedrückt werden.Furthermore, it is conceivable in this context, even the distance from each other in the printing machine introduced large format plates - possibly variable - to program. This can be done in addition to the adjustable stops or separately from these. The variation of the distance in the longitudinal direction can also be expressed as time-delayed insertion of the large format plates into the printing machine.

Die mit dem erfindungsgemäßen Verfahren hergestellten Paneele besitzen eine verschleißfeste Oberfläche, das heißt insbesondere einen Abriebwiderstand größer AC1 gemäß der Norm EN 13329:2000. Auch ist es denkbar, dass in der Druckmaschine eine Oberflächenstruktur in Anpassung an das Dekor erzeugt wird.The panels produced by the method according to the invention have a wear-resistant surface, that is to say in particular an abrasion resistance greater than AC1 according to the standard EN 13329: 2000. It is too conceivable that in the printing machine, a surface structure is created in adaptation to the decor.

Die Erfindung ist nachfolgend anhand von in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:

The invention is explained in more detail with reference to exemplary embodiments illustrated in the drawings. Show it:

Mit 1 ist in den Figuren 1 und 2 im Schema eine Druckmaschine bezeichnet, in der drucktechnisch vorbereitete Großformatplatten 2 auf einer Oberfläche 3 mit einem Dekor 4 bedruckt werden. Beim Ausführungsbeispiel der Figuren 1 und 2 handelt es sich bei dem Oberflächendekor 4 um naturgetreue Holznachbildungen in der Art eines Dreistabmusters, das in der Fig. 2 bei einer aus der Druckmaschine 1 ausgetretenen Großformatplatte 2 zu erkennen ist.With 1 is in the FIGS. 1 and 2 in the diagram denotes a printing press in which large format plates prepared by printing technology 2 are printed on a surface 3 with a decoration 4. In the embodiment of FIGS. 1 and 2 is the surface decoration 4 lifelike wood imitations in the manner of a three-tone pattern, which in the Fig. 2 can be seen in a leaked from the printing press 1 large format plate 2.

Unter Großformatplatten 2 werden im Rahmen der Ausführungsbeispiele solche mit einer Breite B von üblicherweise > 1,25 m, vorzugsweise > 2 m, und einer Länge L von 2,60 m bis 5,20 m verstanden. Diese Maße können aber auch variieren und dienen nur zur Veranschaulichung der ungefähren Dimensionen von Großformatplatten.In the context of the exemplary embodiments, large format plates 2 are understood to mean those having a width B of usually> 1.25 m, preferably> 2 m, and a length L of 2.60 m to 5.20 m. However, these dimensions may vary and serve only to illustrate the approximate dimensions of large format plates.

In der Druckmaschine 1 befindet sich eine um eine horizontale Achse 5 rotierende Druckwalze 6, deren Oberfläche 7 mit dem für die Großformatplatten 2 gewünschten Dekor versehen ist. Mit dieser Druckwalze 6 wird ein erster Farbton aufgetragen, wobei weitere Druckwalzen, mit denen weitere Farbtöne aufgebracht werden können, nicht dargestellt sind, da das Erfindungsprinzip vollständig anhand einer Druckwalze erläuterbar ist. Im Bereich der Druckmaschine 1 sind quer verlagerbare Anschläge 8, 9 angeordnet, deren maximaler Abstand A größer als die Breite B einer Großformatplatte 2 bemessen ist. Die Querverlagerbarkeit der Anschläge 8, 9 ist durch die Pfeile Pf veranschaulicht. Die Anschläge 8, 9 ermöglichen es, eine Großformatplatte 2 entweder an dem linken, ersten Anschlag 8 oder an dem rechten, zweiten Anschlag 9 in deren dargestellten Endpositionen oder in einer beliebigen Zwischenposition vorbei und der Druckwalze 6 zuzuführen. Auf diese Weise erhalten die zu bedruckenden Oberflächen 3 der Großformatplatten 2 voneinander abweichende Oberflächendekors 4, wodurch auch die letztlich aus den Großformatplatten 2 abgeteilten Paneele - in der Figur 2 mit 10 strichpunktiert angedeutet - eine größere Anzahl unterschiedlicher Oberflächendekors aufweisen. Die Attraktivität einer mit solchen Paneelen 10 belegten Boden-, Wand- oder Deckenfläche wird größer, weil durch die Vielfalt an unterschiedlichen Oberflächendekors die Gleichförmigkeit aufgehoben ist.In the printing machine 1 is a rotating about a horizontal axis 5 pressure roller 6, the surface 7 is provided with the desired for the large format plates 2 decor. With this pressure roller 6, a first hue is applied, with further pressure rollers, with which more shades can be applied, are not shown, since the principle of the invention can be explained in detail with reference to a pressure roller. In the field of printing press 1 transversely displaceable stops 8, 9 are arranged, whose maximum distance A is greater than the width B of a large format plate 2 is dimensioned. The Querverlagerbarkeit the stops 8, 9 is illustrated by the arrows Pf. The stops 8, 9 make it possible to supply a large format plate 2 either on the left first stop 8 or on the right, second stop 9 in its illustrated end positions or in any intermediate position over and the pressure roller 6. In this way, the surfaces to be printed 3 of the large format plates 2 receive different surface decor 4, whereby the ultimately separated from the large format panels 2 panels - in the FIG. 2 indicated by dash-dotted lines - have a greater number of different surface decorations. The attractiveness of such a panel 10 occupied floor, wall or ceiling surface is larger because the uniformity is offset by the variety of different surface decor.

Die Figur 1 zeigt ferner als Beispiel, dass die gemäß den Pfeilen Pf1 in die Druckmaschine 1 eingeführten Großformatplatten 2 nicht nur direkt ohne Abstand sondern auch mit Abstand A1 zueinander folgen können. Dieser Abstand A1 ist außerdem variierbar. Durch die Variation des Abstands A1 treffen die Großformatplatten 2 zu Beginn des Druckvorgangs auf unterschiedliche Umfangsbereiche der Druckwalze 6. Die Großformatplatten 2 werden gesteuert zeitversetzt, das heißt mit unterschiedlichen Abständen A1 der Druckwalze zugeführt. Aufgrund dessen ist die Dekorvielfalt nochmals vergrößerbar.The FIG. 1 also shows as an example that the introduced according to the arrows Pf1 in the printing press 1 large format plates 2 not only directly without spacing but also with distance A1 can follow each other. This distance A1 is also variable. As a result of the variation of the distance A1, the large format plates 2 strike different circumferential regions of the pressure roller 6 at the beginning of the printing process. The large format plates 2 are controlled in a time-delayed manner, that is to say fed at different distances A1 to the pressure roller. Because of this, the variety of decor is again increased.

Ferner lässt die Figur 1 erkennen, dass bei dem dargestellten Oberflächendekor 4 in Form eines Dreistabdrucks als Ausführungsbeispiel die Querversetzung der Großformatplatten 2 relativ zueinander um jeweils mindestens die Breite B1 eines Stabs 11 erfolgen kann.Furthermore, the leaves FIG. 1 recognize that in the illustrated surface decor 4 in the form of a three-dimensional printing as an embodiment, the transverse displacement of the large format plates 2 relative to each other by at least the width B1 of a rod 11 can be carried out.

In der Figur 2 ist noch dargestellt, dass beispielsweise jede zweite aus der Druckmaschine 1 ausgetretene bedruckte Großformatplatte 2 in ihrer horizontalen Ebene um ihre vertikale Mittelachse 12 gemäß dem eingezeichneten Pfeil Pf2 um 180° gedreht werden kann, bevor diese Großformatplatte 2 dann in einzelne Paneele 10 aufgetrennt wird und die Paneele 10 anschließend in aller Regel randseitig profiliert werden. Bei der Profilierung kann es sich z.B. um eine leimfreie Nut/Feder-Profilierung nach Art eines Klicksystems handeln. Das Verdrehen einer Großformatplatte 2 erhöht zusätzlich die Dekorvielfalt auf den letztlich einem Anwender zur Verfügung gestellten Paneelen 10.In the FIG. 2 is still shown that, for example, every second out of the printing machine 1 leaked large format plate 2 can be rotated in its horizontal plane about its vertical center axis 12 according to the plotted arrow Pf2 by 180 ° before this large format plate 2 then into individual Panels 10 is separated and the panels 10 are then profiled usually marginal. The profiling may be, for example, a glue-free tongue and groove profiling in the manner of a click system. The twisting of a large format plate 2 additionally increases the variety of decor on the ultimately made available to a user panels 10th

In der Figur 3 ist anhand von vier bedruckten Großformatplatten 2a-d dargestellt, wie mit einer Längs- und/oder Querversetzung der Großformatplatten 2a-d beim Einführen in eine Druckmaschine 1 das jeweilige Oberflächendekor 4a-d verändert werden kann.In the FIG. 3 is illustrated by four printed large format plates 2a-d, as with a longitudinal and / or transverse displacement of the large format plates 2a-d when inserted into a printing machine 1, the respective surface decoration 4a-d can be changed.

Man erkennt aufgrund der unterbrochenen Linienführungen 13 auf den Großformatplatten 2a-d, dass diese jeweils in 16 Paneele 10 aufgetrennt werden sollen.It can be seen due to the broken lines 13 on the large format plates 2a-d that they are to be separated into 16 panels 10 respectively.

Das Oberflächendekor 4a der Großformatplatte 2a in Figur 3 links oben besteht - lediglich als beliebig veränderbares Beispiel - aus zwei in Längsrichtung der Großformatplatte 2a aufeinander folgenden identischen Dekorbildern 14. Die Identität der Dekorbilder ergibt sich dadurch, dass die Großformatplatte 2a doppelt so lang ist, wie der Umfang der Druckwalze 6, das heißt der Rapport. Nach dem Auftrennen der Großformatplatte 2a entlang ihrer Mittelquerebene MQE ergeben sich daher zwei identisch bedruckte Platten, die entlang der unterbrochenen Linienführungen 13 in jeweils acht Paneele 10 aufgeteilt werden. Wenn dann nach dem Abteilen aus der Großformatplatte 2a die Paneele 10 mit einer insbesondere leimfreien Nut/Feder-Profilierung an den Längsseiten 14, 15 versehen werden, liegen insgesamt 8 x 2 Paneele mit acht unterschiedlichen Oberflächendekors vor. Wenn eine Hälfte der bedruckten Großformatplatte 2a nun um 180° um ihre Mittelhochachse gedreht wird, so dass die Nut/Feder-Profilierung umgekehrt zu der anderen Hälfte angebracht wird, ist es möglich, aus einer einzigen Großformatplatte 2a 16 unterschiedliche Paneele 10 herzustellen. Die Anzahl von 16 Paneelen ist in diesem Ausführungsbeispiel beliebig gewählt. Es werden jedoch gewisse Proportionen als zweckmäßig angesehen, die sich nicht zuletzt aufgrund der verwendeten Druckwalzen ergeben. Üblich sind Druckwalzen mit einem Durchmesser von ca. 40 cm, so dass das Druckbild eine Länge von 1,10 m bis 1,40 m hat bei Großformatplatten mit einer Breite in einem Bereich von 1,25 m bis 2,10 m und einer Länge von 2,60 m bis 5,20 m. Bei einer typischen Großformatplatte mit einer Breite von 2,10 m und einer Paneelbreite von 195 mm ± 10 mm ergeben sich 10 bis 11 unterschiedlich bedruckte Einzelpaneele nebeneinander, die anschließend aus einer einzigen Großformatplatte gewonnen werden können. Bei einer Paneelbreite von 175 mm ± 10 mm ergeben sich 11 bis 12 Paneele über die Breite, bei einer Paneelbreite von 150 mm ± 10 mm 13 bis 15 Paneele, bei einer Paneelbreite von 130 mm ± 10 mm 15 bis 17 Paneele, bei einer Paneelbreite von 120 mm ± 10 mm 16 bis 19 Paneele und bei einer Paneelbreite von 95 mm ± 10 mm 20 bis 24 Paneele. Diese Angaben beziehen sich darauf, dass die einzelnen Paneele eine Länge zwischen 1,00 m und 1,35 m haben. Bei kürzeren Paneelen mit einer Länge in einem Bereich von 0,75 m bis 1,00 m ist es möglich, die Anzahl der mit einem unterschiedlichen Dekor bedruckten Paneele zu verdoppeln. Das heißt, dass beispielsweise bei einer Paneelbreite von 120 mm ± 10 mm 32 bis 38 Paneele mit jeweils unterschiedlichem Dekor bedruckt werden können. Bei einer Paneelbreite von 95 mm ± 10 mm ergeben sich sogar 40 bis 48 unterschiedlich bedruckte Paneele. Wenn zudem jede zweite auf diese Weise bedruckte Großformatplatte vor dem Auftrennen in einzelne Paneele um 180° gedreht wird, werden Nut und Feder vertauscht, so dass sich die Anzahl der unterschiedlichen Dekors durch den Faktor 2 nochmals verdoppelt. Auf diese Weise ist es möglich, einen wesentlich attraktiveren Bodenbelag aus Einzelpaneelen herzustellen, dessen optischer Gesamteindruck durch die Vielfalt und das abwechslungsreiche Dekor entscheidend verbessert wird, ohne dass der Herstellungsaufwand hierfür signifikant erhöht werden müsste.The surface decoration 4a of the large format plate 2a in FIG FIG. 3 The identity of the decorative images results from the fact that the large format plate 2a is twice as long as the circumference of the pressure roller 6, that is the Rapport. After separating the large format plate 2a along its median transverse plane MQE, therefore, two identically printed plates are obtained, which are divided along the broken line guides 13 into eight panels 10 each. If, after being separated from the large format plate 2a, the panels 10 are provided with a particularly glue-free tongue / groove profiling on the longitudinal sides 14, 15, there are a total of 8 × 2 panels with eight different surface decorations. If one half of the printed large format plate 2a is now rotated through 180 ° about its central vertical axis, so that the groove / tongue profiling is applied inversely to the other half, it is possible to produce 16 different panels 10 from a single large format plate 2a. The number of 16 panels is arbitrary in this embodiment. However, certain proportions are considered to be appropriate, resulting not least because of the pressure rollers used. Usual are printing rollers with a diameter of about 40 cm, so that the printed image has a length of 1.10 m to 1.40 m in large format plates having a width in a range of 1.25 m to 2.10 m and a length from 2.60 m to 5.20 m. In a typical large format plate with a width of 2.10 m and a panel width of 195 mm ± 10 mm, 10 to 11 different printed individual panels result side by side, which can then be obtained from a single large format plate. With a panel width of 175 mm ± 10 mm, 11 to 12 panels will result in the width, with a panel width of 150 mm ± 10 mm 13 to 15 panels, with a panel width of 130 mm ± 10 mm 15 to 17 panels, with a panel width from 120 mm ± 10 mm 16 to 19 panels and with a panel width of 95 mm ± 10 mm 20 to 24 panels. This information refers to the fact that the individual panels have a length between 1.00 m and 1.35 m. For shorter panels with a length in the range of 0.75 m to 1.00 m, it is possible to double the number of panels printed with a different décor. This means that, for example, with a panel width of 120 mm ± 10 mm, 32 to 38 panels, each with a different decor, can be printed. With a panel width of 95 mm ± 10 mm, there are even 40 to 48 differently printed panels. In addition, if every second printed in this way large format plate is rotated by 180 ° before separating into individual panels, tongue and groove are reversed, so that doubles the number of different decorations by a factor of 2 again. In this way, it is possible to produce a much more attractive floor covering of individual panels, the overall visual impression of which is decisively improved by the variety and the varied decor, without the production cost for this would have to be significantly increased.

Im Falle der Ausführungsform eines Oberflächendekors 4 der Großformatplatte 2b ist diese beim Einführen in die Druckmaschine 1 im Vergleich zu der Großformatplatte 2a um die halbe Breite eines Paneels 10 nach links versetzt worden. Folglich sind die einzelnen Paneele 10 vollständig anders bedruckt.In the case of the embodiment of a surface decoration 4 of the large format plate 2b, this has been displaced to the left by half the width of a panel 10 when inserted into the printing machine 1 compared to the large format plate 2a. Consequently, the individual panels 10 are printed completely differently.

Betrachtet man die Großformatplatten 2a und 2b gemeinsam, so liegen nach dem Zerteilen in Paneele insgesamt 32 Paneele 10 mit 16 voneinander abweichenden Oberflächendekoren vor, ohne dass das Dekormuster auf einer Druckwalze geändert wurde.Looking at the large format plates 2a and 2b together, so are after dividing into panels a total of 32 panels 10 with 16 divergent Oberflächendekoren ago, without the decor pattern was changed on a platen.

Anhand der Großformatplatte 2c in Figur 3 rechts oben erkennt man ein Oberflächendekor 4c, bei welchem ein Versatz in Längsrichtung gegenüber dem Dekor 4a auf der Großformatplatte 2a erfolgt ist. Dadurch ändern sich wiederum die Oberflächendekore der nebeneinander liegenden Paneele 10, so dass jetzt zusammen mit den Oberflächendekors 4a und 4b der Großformatplatten 2a und 2b insgesamt 24 unterschiedlich bedruckte einzelne Paneele vorliegen bei einer Gesamtzahl von nur 48 Paneelen.Based on the large format plate 2c in FIG. 3 The top right recognizes a surface decor 4c in which an offset in the longitudinal direction relative to the decor 4a on the large format plate 2a has taken place. This in turn changes the surface decorations of the adjacent panels 10, so that together with the surface decorations 4a and 4b of the large format panels 2a and 2b a total of 24 differently printed individual panels are present with a total of only 48 panels.

Wenn die Großformatplatte 2d gemäß der Figur 3 rechts unten schließlich sowohl seitlich versetzt wird als auch in Längsrichtung, ergibt sich wiederum ein anderes Druckbild auf den einzelnen Paneelen 10. In diesem Fall würde sich die Anzahl der unterschiedlich bedruckten Paneele auf 32 erhöhen bei einer Gesamtzahl der Paneele von 64. Wenn zusätzlich noch jeweils die in der Bildebene untere Hälfte einer jeden Großformatplatte 2a, 2b, 2c, 2d nach einem Trennschnitt entlang ihrer Mittelquerebene MQE um 180° gedreht wird, so dass die Nut/Feder-Profilierung der unteren Hälfte umgekehrt zur oberen Hälfte angebracht wird, ergeben sich 64 unterschiedlich bedruckte Paneele 10 bei der Verwendung nur einer einzigen Druckwalze. Durch Variation des seitlichen Versatzes sowie Veränderung des Versatzes in Längsrichtung ist es theoretisch und praktisch möglich, mit ein und derselben Druckwalze beliebig viele unterschiedlich bedruckte Paneele herzustellen, wobei das Druckbild zweier auf diese Weise hergestellten Paneele 10 immer etwas unterschiedlich ist.When the large size plate 2d according to FIG. 3 Finally, bottom right and finally offset laterally as well as in the longitudinal direction, in turn results in a different printed image on the individual panels 10. In this case, the number of differently printed panels would increase to 32 for a total number of panels of 64. If in addition to each the bottom half of each large format plate 2a, 2b, 2c, 2d rotated by 180 ° in the image plane along its central transverse plane MQE, so that the groove / tongue profiling of the lower half is mounted inversely to the upper half, 64 result different printed panels 10 when using only a single pressure roller. By varying the lateral offset and changing the offset in the longitudinal direction, it is theoretically and practically possible to produce as many differently printed panels with one and the same pressure roller, wherein the printed image of two panels 10 produced in this way is always slightly different.
