Description

Verfahren zum Bedrucken von Druckpapier und mit einem Dekor bedrucktes Druckpapier Process for printing on printing paper and printing paper printed with a decor
Die Erfindung betrifft ein Verfahren zum Bedrucken von Druckpapier von ei- ne Rolle mit einem wenigstens ein Dekorbild aufweisenden Dekor zur Verwendung bei flächigen Bauteilen, insbesondere für Boden-, Wand-, Deckenoder Möbelanwendungen, wobei auf dem Druckpapier zusätzlich zu dem Dekor randseitig Cut-Markierungen aufgedruckt werden, die benachbarte Papierabschnitte definieren, auf denen sich jeweils Dekorbilder befinden. Des weite- ren betrifft die vorliegende Erfindung ein mit einem Dekor bedrucktes Druckpapier.The invention relates to a method for printing on printing paper from a ne role with a decor having at least one decor for use in flat components, in particular for floor, wall, ceiling or furniture applications, wherein on the printing paper in addition to the decor edge cut marks imprinting, which define adjacent paper sections, on each of which decor images are located. Furthermore, the present invention relates to a print paper printed with a decor.
Ein Verfahren der vorgenannten Art ist aus der Praxis bereits seit Jahrzehnten bekannt. Üblicherweise wird Druckpapier von der Rolle im Rotations- bzw. Tiefdruck bedruckt. Die dabei verwendeten Druckzylinder weisen das aufzudruckende Dekor als Negativbild auf. Randseitig sind auf den Druckzylindern sowohl Cut- als auch Ausrichtmarkierungen vorgesehen. Die Cut-Markierungen dienen dazu, diejenigen Stellen anzuzeigen, an denen das Druckpapier anschließend zu einzelnen Bögen geschnitten wird. Üblicherweise werden Cut- Markierungen auch als "Schneid(e)marken" oder "Schnittmarken" bezeichnet. Die Ausrichtmarkierungen dienen letztlich zur Ausrichtung bei der Weiterverarbeitung der Bögen.A method of the aforementioned type has been known from practice for decades. Usually, printing paper is printed by the roll in rotary or gravure printing. The printing cylinders used have the decor to be printed on as a negative image. On the edge side both cut and alignment marks are provided on the printing cylinders. The cut marks serve to indicate those locations where the printing paper is subsequently cut into individual sheets. Usually, cut marks are also referred to as "cut marks" or "cut marks". The alignment marks ultimately serve for alignment during the further processing of the sheets.
Die Bedruckung von Druckpapier im Rotationsdruck bietet sich insbesondere an, wenn Druckpapier mit einem bestimmten Dekor in großen Mengen benötigt wird. Für einen Dekorwechsel ist es erforderlich, die Druckzylinder zu wechseln, was vergleichsweise aufwendig ist. Problematisch ist, daß es vergleichsweise häufig vorkommt, daß bestimmte Dekore nur in ganz geringen Mengen benötigt werden. Das Bedrucken im Rotationsdruck ist dann, bezo- gen auf die geringe zu bedruckende Menge an Druckpapier, nicht nur wegen der notwendigen Umrüstung vergleichsweise aufwendig, sondern auch relativ teuer, da die Kosten für entsprechende Druckzylinder mit anderen Dekoren vergleichsweise hoch sind. Aufgabe der vorliegenden Erfindung ist es nun, ein Verfahren der eingangs genannten Art zur Verfügung zu stellen, bei dem sich auch geringe Mengen an Druckpapier kostengünstig und schnell bedrucken lassen.The printing of printing paper in rotary printing is particularly useful when printing paper with a certain decor is required in large quantities. For a decorative change, it is necessary to change the impression cylinder, which is relatively expensive. The problem is that it is comparatively common that certain decors are needed only in very small quantities. The printing in rotary printing is then, relative to the small amount of printing paper to be printed, not only because of the necessary conversion relatively expensive, but also relatively expensive, since the cost of corresponding printing cylinder with other decors are relatively high. Object of the present invention is therefore to provide a method of the type mentioned, in which even small amounts of printing paper can be printed inexpensively and quickly.
Die vorgenannte Aufgabe ist erfindungsgemäß im wesentlichen dadurch gelöst, daß das Druckpapier mittels eines digitalen Druckverfahrens durch eine digitale Druckvorrichtung bedruckt wird und nach einer Unterbrechung des Druckvorgangs und anschließender Fortsetzung wenigstens eine Cut- Markierung in Abhängigkeit der Druckqualität und/oder der Funktion der di- gitalen Druckvorrichtung gedruckt wird. Dabei ist es zweckmäßigerweise so, daß gleichzeitig oder anschließend mit dem Druck der Cut-Markierung damit begonnen wird, ein neues Dekorbild zu drucken.The above object is achieved according to the invention essentially in that the printing paper is printed by a digital printing method by a digital printing device and after an interruption of the printing operation and subsequent continuation at least one cut mark depending on the print quality and / or the function of the digital Printing device is printed. It is expediently so that simultaneously or subsequently with the pressure of the cut mark is begun to print a new decor image.
Der Erfindung liegt zunächst einmal der Grundgedanke zugrunde, statt des Rotationsdruckverfahrens auf ein Digitaldruckverfahren zurückzugreifen. Mittels einer digitalen Druckvorrichtung lassen sich sehr einfach und kostengünstig computergestützt unterschiedlichste Dekore kreieren. Dabei ist die Druckqualität eines digitalen Druckverfahrens mit der des Rotationsdruckes vergleichbar. Die Erfindung ist jedoch nicht auf die Anwendung des digitalen Druckverfahrens, das als solches bekannt ist, beschränkt. Aus der Praxis ist es bekannt, das digitale Druckverfahren zum Bedrucken von Druckpapier zur Verwendung bei flächigen Bauteilen, wie beispielsweise Paneelen, auf einzelnen Bögen anzuwenden. Es ist auch bekannt, die Bauteile als solche zu bedrucken. Ein Bedrucken des Druckpapiers von der Rolle her ist bisher nicht vorgenommen worden. Dementsprechend war es bisher auch nicht erforderlich, entsprechende Markierungen auf den digital bedruckten Druckpapierbögen vorzusehen.The basic idea of the invention is to use a digital printing method instead of the rotary printing method. By means of a digital printing device can be very simple and inexpensive computer-aided create a variety of decors. The print quality of a digital printing process is comparable to that of rotary printing. However, the invention is not limited to the application of the digital printing method known as such. From practice it is known to apply the digital printing method for printing on printing paper for use with sheet-like components, such as panels, on individual sheets. It is also known to print the components as such. A printing of the printing paper from the roll forth has not been made. Accordingly, it has hitherto not been necessary to provide corresponding markings on the digitally printed printing paper sheets.
Bei der Erfindung ist es nun so, daß, anders als beim Rotationsdruck, wo die Cut- und/oder Ausrichtmarkierungen immer an der gleichen Stelle vorgesehen sind, sich aufgrund des feststehenden Zylinderdurchmessers also in regelmäßigen Abständen wiederholen, hier eine Cut-Markierung variabel angeordnet wird. Die variable Anordnung der Cut-Markierung erfolgt in Abhängigkeit der Druckqualität des Dekors und/oder der Funktion der digitalen Druckvorrich- tung. Letztlich wird bei der Erfindung also entweder der Zustand bzw. die Funktion der digitalen Druckvorrichtung, bei der es sich beispielsweise um einen Ink-Jet-Drucker handeln kann, übeφrüft, beispielsweise anhand bestimmter Betriebstemperaturen, oder es wird die Druckqualität des Dekors entsprechend automatisch überwacht. Ist beispielsweise die Druckqualität bei einem Wiederanlaufen der digitalen Druckvorrichtung bzw. Fortsetzen des Druckvorgangs schlecht, wird zunächst keine Cut-Markierung gesetzt. Erst wenn die Druckqualität des Dekors den notwendigen Anforderungen entspricht, wird eine entsprechende Cut-Markierung gesetzt. Mit dem Drucken einer Cut-Markierung ist verbunden, daß gleichzeitig oder anschließend begonnen wird, ein neues Dekorbild zu drucken.In the invention, it is now so that, unlike the rotary printing, where the cut and / or alignment marks are always provided at the same location, so repeat due to the fixed cylinder diameter so at regular intervals, here a cut mark is variably arranged , The variable arrangement of the cut marking takes place as a function of the print quality of the decoration and / or the function of the digital printing device. Ultimately, in the invention, either the state or the function of the digital printing device, which is for example at can act an ink-jet printer übeφrüft, for example, based on certain operating temperatures, or it is the print quality of the decor accordingly monitored automatically. If, for example, the print quality is poor when the digital printing device resumes or the printing process continues, no cut mark is initially set. Only when the print quality of the decor meets the necessary requirements, a corresponding cut mark is set. Printing a cut mark entails simultaneously or subsequently starting printing a new decor image.
Grundsätzlich ist es möglich, daß der Druck einer Cut-Markierung manuell und/oder automatisch initiierbar ist. So kann beispielsweise die Druckqualität nach einem Fortsetzen des Druckvorgangs manuell überwacht werden. Wird die Druckqualität des Dekors für hinreichend erachtet, wird durch Initiierung eines entsprechenden Befehls mit dem Druck der Cut-Markierung begonnen. Gleichzeitig wird dann auf dem nächsten Papierabschnitt ein neues Dekorbild gedruckt. Bevorzugt ist es natürlich, daß der Druck der Cut-Markierung automatisch initiiert wird. In diesem Falle ist es zweckmäßig, wenn die Druckqualität des Dekors automatisch überwacht wird. Hierdurch kann die Digital- druckvorrichtung letztlich komplett automatisch betrieben werden.In principle, it is possible that the pressure of a cut mark can be initiated manually and / or automatically. For example, the print quality can be manually monitored after resuming the printing process. If the print quality of the decor is considered adequate, initiate an appropriate command to start printing the cut mark. At the same time, a new decorative image is then printed on the next paper section. It is preferable, of course, that the pressure of the cut mark be automatically initiated. In this case, it is expedient if the print quality of the decor is automatically monitored. As a result, the digital printing device can ultimately be operated completely automatically.
Von besonderem Vorteil ist es in diesem Zusammenhang, wenn die Druckqualität des Dekors mittels einer optischen Überwachungseinrichtung überwachbar ist, die der Digitaldruckvorrichtung zugeordnet ist. Dabei sollte vor- zugsweise vorgesehen sein, daß die optische Überwachungseinrichtung das aktuelle Druckergebnis nach einer Unterbrechung und anschließender Fortsetzung des Druckvorgangs mit einer vorgegebenen Druckqualität vergleicht und bei einer vorgegebenen Übereinstimmung des aktuellen Druckergebnisses mit der vorgegebenen Druckqualität den Druck einer Cut-Markierung automatisch initiiert. Gleichzeitig wird damit ein neuer Papierabschnitt definiert und mit dem Druck des Dekorbildes auf diesem Papierabschnitt begonnen.It is particularly advantageous in this context if the print quality of the decoration can be monitored by means of an optical monitoring device which is associated with the digital printing device. It should preferably be provided that the optical monitoring device compares the current print result after an interruption and subsequent continuation of the printing process with a predetermined print quality and automatically initiates the print of a cut mark at a predetermined match of the current print result with the predetermined print quality. At the same time a new paper section is defined and started with the printing of the decorative image on this paper section.
Grundsätzlich ist es möglich, daß die Überwachungseinrichtung unmittelbar die Druckqualität des Dekors und damit das Dekorbild im Hinblick auf seine Druckqualität überwacht. In diesem Falle ist ein entsprechender Sensor oberhalb des Dekors angeordnet und vergleicht dann die Druckqualität des Dekor- bildes mit der vorgegebenen Druckqualität. Es findet also ein Ist-Soll- Vergleich des Dekorbildes als solches bzw. dessen Farben statt.In principle, it is possible that the monitoring device directly monitors the print quality of the decor and thus the decor image with regard to its print quality. In this case, a corresponding sensor is arranged above the decoration and then compares the print quality of the decor picture with the specified print quality. Thus, there is an actual target comparison of the decorative image as such or its colors.
Bei einer besonders bevorzugten Ausfuhrungsform der vorliegenden Erfin- düng wird die Druckqualität des Dekors bzw. des Dekorbildes nicht unmittelbar aus dem gedruckten Dekorbild abgeleitet, sondern aus einer Randstreifenmarkierung, die randseitig fortlaufend und parallel zum Dekor gedruckt wird. Diese Randstreifenmarkierung weist wenigstens einen längslaufenden Farbstreifen auf. Aus der Druckqualität des Randstreifens wird dann die Druckqualität des Dekors insgesamt abgeleitet.In a particularly preferred embodiment of the present invention, the printing quality of the decoration or the decorative image is not derived directly from the printed decorative image, but from a marginal strip marking, which is continuously printed on the edge and parallel to the decor. This edge strip marking has at least one longitudinal color strip. From the print quality of the marginal strip, the print quality of the decor is then derived as a whole.
Besonders bevorzugt ist es in diesem Zusammenhang, daß die Farbe des Farbstreifens der Farbe des Druckkopfes entspricht. Hierbei wird dann die Farbe des Randstreifens der Randstreifenmarkierung überwacht. Ein solcher Farb- vergleich ist in der Regel einfacher vorzunehmen als ein Farbvergleich innerhalb eines gesamten Dekorbildes. Auch hier erfolgt letztlich ein Ist-Soll- Vergleich der Farbe des Randstreifens mit der vorgegebenen Farbe des betreffenden Druckkopfes.It is particularly preferred in this context that the color of the color strip corresponds to the color of the print head. In this case, the color of the edge strip of the edge strip marking is then monitored. Such a color comparison is usually easier to do than a color comparison within an entire decor image. Again, there is ultimately an actual-target comparison of the color of the edge strip with the specified color of the printhead in question.
Besonders günstig ist es in diesem Zusammenhang, daß die Anzahl der Farbstreifen der Randstreifenmarkierung der Anzahl der aktiven Druckköpfe der Druckvorrichtung entspricht. Auf diese Weise kann dann festgestellt werden, ob alle aktiven Druckköpfe funktionieren und Druckfarbe in der gewünschten Qualität abgeben. Wird bei der Randstreifenüberwachung eine Qualitätsein- schränkung festgestellt, bedeutet dies, daß auch das Dekorbild Qualitätseinschränkungen hat.It is particularly favorable in this context that the number of color stripes of the edge strip marking corresponds to the number of active print heads of the printing device. In this way, it can then be determined whether all active printheads work and deliver ink of the desired quality. If a quality restriction is detected during borderline monitoring, this means that the decor image also has quality restrictions.
Im übrigen bezieht sich die vorliegende Erfindung auch auf ein mit einem Dekor bedrucktes Druckpapier auf einer Rolle mit einem wenigstens ein Dekor- bild aufweisenden Dekor zur Verwendung bei flächigen Bauteilen, insbesondere Boden-, Wand-, Decken- oder Möbelanwendungen, wobei auf dem Druckpapier zusätzlich zu dem Dekor randseitig Cut-Markierungen aufgedruckt sind, wobei die Cut-Markierungen benachbarter Papierabschnitte definieren, auf denen sich jeweils ein Dekorbild befindet und wobei Cut- Markierungen in unregelmäßigen Abständen in Längsrichtung des Druckpapiers vorgesehen sind. Darüber hinaus betrifft die vorliegende Erfindung ein mit einem Dekor bedrucktes Druckpapier mit einer randseitig fortlaufenden, parallel zum Dekor verlaufenden Randstreifenmarkierung mit wenigstens einem längslaufenden Farbstreifen, wobei die Farbe des Farbstreifens in der Farbe des Dekors enthalten ist. Dabei versteht es sich, daß es grundsätzlich möglich und auch bevorzugt ist, die vorgenannte Randstreifenmarkierung sowie die randseitig vorgesehenen regelmäßigen und unregelmäßigen Cut-Markierungen gemeinsam vorzusehen.Moreover, the present invention also relates to a printing paper printed on a roll with a decor having at least one decor for use in flat components, in particular floor, wall, ceiling or furniture applications, wherein additionally on the printing paper to the decor edge markings are printed, the cut markings define adjacent paper sections, on each of which a decorative image is located and wherein cut marks are provided at irregular intervals in the longitudinal direction of the printing paper. In addition, the present invention relates to a printed with a decorative printing paper with a continuous edge, parallel to the decor edge trim with at least one longitudinal color strip, wherein the color of the colored strip is included in the color of the decor. It is understood that it is basically possible and also preferable to provide the aforementioned marginal strip marking and the regular and irregular cut markings provided on the edge together.
Schließlich betrifft die vorliegende Erfindung eine digitale Druckvorrichtung mit einer optischen Überwachungseinrichtung zur Überwachung der Druckqualität des gedruckten Dekorbildes.Finally, the present invention relates to a digital printing device with an optical monitoring device for monitoring the print quality of the printed decorative image.
Nachfolgend wird ein Ausführungsbeispiel der vorliegenden Erfindung anhand der Zeichnung erläutert. In der Zeichnung ist ein Druckpapier 1 in Form einer langgestreckten Bahn von einer Rolle dargestellt. Bei dem Druckpapier 1 kann es sich um übliches beharztes, teilbeharztes oder durchbeharztes Papier handeln, das druckseitig eine Tintenaufnahmeschicht aufweisen kann oder auch nicht. Druckseitig auf dem Druckpapier befindet sich ein aufgedrucktes Dekor 2. Bei dem Dekor 2 kann es sich um jedes beliebige Bild handeln. Das Dekor 2 weist wenigstens ein Dekorbild 3 auf. Vorliegend sind eine Vielzahl von Dekorbildern 3 vorgesehen, die in Längsrichtung L hintereinander angeordnet sind.Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. In the drawing, a printing paper 1 is shown in the form of an elongated web of a roll. The printing paper 1 may be conventional resinated, partially resinated or doctored paper which may or may not have an ink receiving layer on the printing side. Printed on the printing paper is a printed decor 2. The decor 2 can be any image. The decor 2 has at least one decorative image 3. In the present case, a plurality of decorative images 3 are provided, which are arranged one behind the other in the longitudinal direction L.
Zusätzlich zu dem Dekor 2 sind randseitig, und zwar im Randbereich 4, 5 beider Längsränder des Druckpapiers 1, jeweils eine Mehrzahl von Markierungen vorgesehen. Bei den Markierungen handelt es sich einerseits um sogenannte Cut-Markierungen 6, 7, 8 sowie um Ausrichtmarkierungen 9. Die Cut-Markie- rungen 6, 7, 8 und Ausrichtmarkierungen 9 liegen einander jeweils gegenüber. Die einander gegenüberliegenden Cut-Markierungen 6 und die einander gegenüberliegenden Cut- Markierungen 7 definieren einen Papierabschnitt 10, auf dem sich ein Dekorbild 13 befindet.In addition to the decor 2, a plurality of markings are respectively provided on the edge, namely in the edge region 4, 5 of both longitudinal edges of the printing paper 1. On the one hand, the markings are so-called cut marks 6, 7, 8 as well as alignment marks 9. The cut markings 6, 7, 8 and alignment markings 9 face one another in each case. The opposite cut marks 6 and the opposite cut marks 7 define a paper section 10 on which a decorative image 13 is located.
Die Cut-Markierungen 6, 7 dienen vorliegend als Anzeige zum Zerteilen der Druckpapierbahn in einzelne Bögen. Die Ausrichtmarkierungen dienen in die- sem Zusammenhang zur entsprechenden Ausrichtung der Druckpapierbahn. Beim Zerteilen/Zerschneiden der Druckpapierbahn in einzelne Bögen kann auch der jeweilige Papierabschnitt dann weiter zugeschnitten werden. Bei der dargestellten Ausfuhrungsform ist es so, daß das Dekorbild 13 fünf gleiche Dekorabschnitte 14 aufweist, die bei der weiteren Verarbeitung mit platten- förmigen Grundkörpern zu flächigen Bauteilen, wie Paneelen oder Platten zur Boden-, Wand-, Decken- oder Möbelanwendungen verpreßt werden. Im übrigen versteht es sich, daß die Anzahl der Dekorabschnitte nicht auf fünf, wie dies dargestellt ist, beschränkt ist. Es kann auch eine größere oder eine kleine- re Anzahl von Dekorabschnitten pro Dekorbild 13 vorgesehen sein.The cut marks 6, 7 serve in the present case as a display for dividing the printing paper web into individual sheets. The alignment marks are used in these sem context to the corresponding orientation of the printing paper web. When dividing / cutting the printing paper web into individual sheets and the respective paper section can then be further tailored. In the illustrated embodiment, it is such that the decorative image 13 has five identical decor sections 14, which are pressed in the further processing with plate-shaped bodies to sheet-like components, such as panels or panels for floor, wall, ceiling or furniture applications. Incidentally, it is understood that the number of the decorative portions is not limited to five, as shown. It is also possible to provide a larger or a smaller number of decor sections per decorative image 13.
Bei der dargestellten Ausführungsform ist es nun so, daß die einzelnen Cut- Markierungen 6, 7, 8 in unterschiedlichen Abständen zueinander angeordnet sind. Der übliche Abstand zweier Cut-Markierungen und damit das übliche Maß des durch die Cut-Markierungen definierten Papierabschnitts wird durch den Abstand benachbarter Cut-Markierungen 6, 7 an einem Randbereich bestimmt. Der Abstand der Cut-Markierungen 7 und 8 ist erheblich geringer als der Abstand der Cut-Markierungen 6, 7. Der Abstand der Cut-Markierung 8 zur nicht mehr dargestellten aber in Längsrichtung folgenden Cut-Markierung entspricht letztlich wieder dem Abstand der Cut-Markierungen 6, 7.In the illustrated embodiment, it is now so that the individual cut marks 6, 7, 8 are arranged at different distances from each other. The usual distance between two cut marks and thus the usual amount of the paper section defined by the cut marks is determined by the spacing of adjacent cut marks 6, 7 at an edge area. The distance of the cut marks 7 and 8 is considerably smaller than the distance of the cut markers 6, 7. The distance of the cut mark 8 to not shown but in the longitudinal direction following cut mark ultimately corresponds again to the distance of the cut marks 6, 7.
Das Verfahren zum Bedrucken des Druckpapiers 1 erfolgt nun derart, daß das Druckpapier 1 von einer Lehrpapierrolle einer digitalen Druckvorrichtung zugeführt wird. Hierbei kann es sich um einen Ink- Jet-Drucker handeln, über den das Dekor 2 aufgedruckt wird. Vor Beginn des Druckvorganges wird das Druckpapier 1 von der Leerpapierrolle durch eine entsprechende Papierzuführung der digitalen Druckvorrichtung hindurchgeführt zu einer Papierabführung, auf der das Druckpapier 1 zu einer bedruckten Druckpapierrolle aufgewickelt wird. Anschließend kann mit dem Druckvorgang begonnen werden. So wird beispielsweise zum Drucken des Dekorbildes 13 zunächst beidseitig die Cut-Markierung 6 gedruckt. Gleichzeitig dazu wird über die Druckköpfe, die sich an dem an einer Druckerführung verfahrbaren Druckerschlitten befinden, das Dekorbild 13 gedruckt. Nachdem zwischenzeitlich die Ausrichtmarkierungen 9 gedruckt worden sind, werden zum Ende des Dekorbildes 13 die Cut-Markierungen 7 gedruckt. Die Cut-Markierungen 7 bilden dabei einerseits das Ende des Papierabschnittes 10 und den Beginn des seits das Ende des Papierabschnittes 10 und den Beginn des PapierabschnittesThe method for printing on the printing paper 1 is carried out in such a manner that the printing paper 1 is fed from a teaching paper roll to a digital printing device. This can be an inkjet printer, over which the decor 2 is printed. Before the start of printing, the printing paper 1 is passed from the blank paper roll through a corresponding paper feed of the digital printing apparatus to a paper discharge on which the printing paper 1 is wound into a printed printing paper roll. Then you can start printing. For example, to print the decorative image 13, the cut mark 6 is first printed on both sides. At the same time, the decorative image 13 is printed via the print heads, which are located on the printer carriage which can be moved on a printer guide. After the registration marks 9 have been printed in the meantime, the cut marks 7 are printed at the end of the decorative image 13. The cut marks 7 on the one hand form the end of the paper section 10 and the beginning of the on the one hand the end of the paper section 10 and the beginning of the paper section
11 mit einem entsprechenden Dekorbild 13.11 with a corresponding decorative image 13th
Vorliegend sind die einzelnen Dekorbilder 13 auf den Papierabschnitten 10, 11, 12 identisch. Dies muß jedoch nicht so sein. Grundsätzlich können auch unterschiedliche Dekorbilder 13 auf den einzelnen Papierabschnitten 10, 11,In the present case, the individual decorative images 13 on the paper sections 10, 11, 12 are identical. However, this does not have to be the case. In principle, different decor images 13 on the individual paper sections 10, 11,
12 vorgesehen sein.12 may be provided.
Während des Druckes des Dekorbildes 13 auf dem Papierabschnitt 11 wird nun der Druckvorgang unterbrochen. Dies kann beispielsweise aus Wartungsgründen oder zum Austausch eines Tintentanks erforderlich sein. Anschließend wird der Druckvorgang fortgesetzt. Während des gesamten Druckvorgangs wird die Druckqualität des Dekors 2 bzw. des jeweiligen DekorbildesDuring the printing of the decorative image 13 on the paper section 11, the printing process is now interrupted. This may be necessary, for example, for maintenance reasons or to replace an ink tank. Subsequently, printing will continue. Throughout the printing process, the print quality of the decor 2 or the respective decorative image
13 überwacht. Hierbei handelt es sich um eine automatische Überwachung mittels einer im einzelnen nicht dargestellten Überwachungseinrichtung. Wird bei der optischen Überwachung nach der Wiederaufnahme der Drucktätigkeit festgestellt, daß die Druckqualität des Dekorbildes 13 den vorgegebenen Anforderungen entspricht, werden die Cut-Markierungen 8 gedruckt. Die Cut- Markierungen 8 begrenzen den Papierabschnitt 11 und stellen den Beginn des Papierabschnitts 12 mit einem neuen Dekorbild 13 dar.13 monitored. This is an automatic monitoring by means of a monitoring device, not shown in detail. If it is determined in the optical monitoring after the resumption of printing activity that the print quality of the decorative image 13 corresponds to the predetermined requirements, the cut marks 8 are printed. The cut marks 8 delimit the paper section 11 and represent the beginning of the paper section 12 with a new decorative image 13.
Zur Überwachung der Druckqualität weist die optische Überwachungseinrichtung wenigstens einen optischen Sensor 15, 16 auf. Im dargestellten Ausführungsbeispiel ist der optische Sensor 15 unmittelbar auf das Dekorbild 13 ge- richtet, während der optische Sensor 16 auf eine Randstreifenmarkierung 17 gerichtet ist, die parallel zum Dekor 2 randseitig verläuft und parallel und gleichzeitig zu den Dekorbildern 13 gedruckt wird. Die Randstreifenmarkierung 17 weist vorliegend eine Mehrzahl von Randstreifen 18 auf. Die einzelnen Randstreifen 18 sind farbig und entsprechen von ihrer Farbe und Anzahl der Farbe und Anzahl der aktiven Druckköpfe der Druckvorrichtung.For monitoring the print quality, the optical monitoring device has at least one optical sensor 15, 16. In the illustrated embodiment, the optical sensor 15 is directed directly to the decorative image 13, while the optical sensor 16 is directed to a marginal strip 17 which extends parallel to the decor 2 edge and parallel to the decorative images 13 is printed. The edge strip marking 17 in the present case has a plurality of edge strips 18. The individual marginal strips 18 are colored and correspond in color and number to the color and number of active printheads of the printing device.
Die beiden Sensoren 15, 16, die unmittelbar im Anschluß an den Druckerschlitten bzw. die Druckköpfe angeordnet sind, können alternativ oder aber auch gemeinsam vorgesehen sein. In jedem Falle sind die beiden Sensoren 15, 16 letztlich mit einer Steuereinrichtung 19 der Druckvorrichtung 1 gekoppelt, die wiederum einen nicht dargestellten Vergleicher aufweist, bei dem in ei- nem Ist- Soll- Vergleich das aktuelle Druckergebnis mit dem vorgegebenen Soll-Druck-Ergebnis verglichen wird. The two sensors 15, 16, which are arranged immediately following the printer carriage or the print heads, may alternatively or also be provided jointly. In any case, the two sensors 15, 16 are ultimately coupled to a control device 19 of the printing device 1, which in turn has a comparator, not shown, in which In actual-target comparison, the current print result is compared with the predetermined target print result.
