Description

  • The The invention relates to a method and a digital printing device for printing on printing paper withdrawn from a roll, with a decor having at least one decorative image for use at areal Components, in particular for Floor, wall, ceiling or furniture applications, wherein the printing paper by means of a digital printing method by a digital printing device is printed.
  • One Method of the type mentioned is already out of practice known. In digital printing, it sometimes happens that the printing process is interrupted. This is the case, for example, when there is no ink left in the ink tank or maintenance is required. If printing then resumes, it has Decor image currently in print usually quality impairments. The same applies if, for example, during a power failure, the pressure is temporarily interrupted. Prints made in this way can be printed in usually not used in production. Because manufacturing processes usually run automatically, can cause such an error often difficult to determine.
  • From the US 2004/0021724 A1 An ink printer is known in which test patterns can be printed on the edge of the recording paper. The test patterns are analyzed for variations in the paper feed rate and for deviations in the movement of the print head based on image data. In addition, incorrectly operating nozzles can be detected via the test patterns.
  • From the DE 10 2006 057 961 A1 It is known to print decors by means of a digital printing process with freely selectable decors.
  • From the DE 203 03 574 U1 is an image inspection system for a sheetfed offset press for printing on fabric out. In this case, the printing material is monitored by an image recording device and processed the signals obtained in a downstream image processing. It is so that a supplementary printing device is provided, are provided on the basis of the image signals obtained markings to mark points of poor quality.
  • From the DE 600 09 556 T2 For example, a method of fabricating a surface decoration by digital printing methods is known. It is envisaged, in addition to decor images apply markers for controlling subsequent processes on the decor carrier.
  • task the present invention, a printing method and a corresponding to provide digital printing apparatus in which prints with bad quality can be determined in a simple manner.
  • to solution the above object is specified in claim 1 Method and the printing device specified in claim 8 intended.
  • at the method according to the invention it is so that the edge on the printing paper a continuous, parallel to the decor running Edge marker printed with at least one longitudinal color strip which is ultimately printed parallel to the decor, and that the print quality depending on monitored by the edge strip marking becomes. Thus, according to the invention from the print quality of the marginal strip derived the print quality of the decor as a whole. If the marginal strip has poor print quality, it means that too the decor does not have sufficient quality. By the invention Ultimately, therefore, a method is provided that does it in a simple manner allows by an outside edge strip to check if the print quality of the decor overall corresponds to a predetermined print quality.
  • In Compounds of the present invention are in addition to the marginal strip marking to provide cut marks in the edge area of the printing paper. Cut marks are used to indicate those locations then the printing paper to individual bows is cut. Furthermore, you can Alignment marks should be provided, which ultimately align serve in the further processing of the cut sheets. In connection with the method according to the invention is it so that in dependence the print quality decoration after interrupting the printing process and then continuing a cut mark is arranged variably. The variable arrangement of the cut mark takes place dependent on the print quality of the decor. Ultimately, in the invention, therefore, the print quality of the decor accordingly automatically monitored. For example, if the print quality when restarting the digital printing device or resume the printing process bad, will be first no cut mark set. Only when the print quality of the decor meets the necessary requirements, is a corresponding Cut mark set. With the printing of a cut mark is connected at the same time or afterwards started to print a new decor image.
  • It is particularly preferred in this context that the color of the color strip of the Color of the printhead corresponds. In this case, the color of the edge strip of the edge strip marking is then monitored. Such 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 predetermined color of the printhead in question.
  • Especially Cheap It is in this context that the number of color stripes the edge banding of the number of active printheads of Printing device corresponds. In this way can then be determined whether all active printheads work and deliver ink in the desired quality. Used in borderline surveillance a quality restriction, means this, too the decor image quality restrictions Has.
  • Basically it is possible that the Print a cut mark manually and / or automatically initiated is. For example, the print quality after resuming the Manual printing monitored become. Will the print quality of decoration for is considered sufficient, by initiation of an appropriate Command started printing the cut mark. simultaneously will be on the next one Paper section printed a new decor image. It is of course preferable that the pressure the cut mark is automatically initiated. In this case is it is useful if the print quality the decor is automatically monitored becomes. As a result, the digital printing device ultimately complete be operated automatically.
  • From It is particularly advantageous in this context if the print quality of the decor means an optical monitoring device monitored is associated with the digital printing device. It should preferably be provided that the optical monitoring device the current print result after an interruption and subsequent continuation comparing the printing process with a given print quality and at a given match the current print result with the specified print quality the pressure automatically initiated a cut mark. At the same time it will a new section of paper defined and with the pressure of the decor image started on this paper section.
  • Basically it is possible that the monitoring device Immediately the print quality of the Decorations and thus the decor image monitored in terms of print quality. In this case, a corresponding sensor above the decor arranged and then compares the print quality of the decor image with the given Print quality. So it finds an actual-target comparison the decorative picture as such or its colors instead.
  • Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. In the drawing is a printing paper 1 represented in the form of an elongated web of a roll. At the printing paper 1 it may be conventional resinous, semi-finished or perfumed paper which may or may not have an ink-receiving layer on the printing side. On the printing side of the printing paper is a printed decor 2 , In the decor 2 it can be any picture. The decor 2 has at least one decorative image 3 on. Here are a variety of decorative images 3 provided, which are arranged one behind the other in the longitudinal direction L.
  • In addition to the decor 2 are on the edge, in the edge area 4 . 5 both longitudinal edges of the printing paper 1 , Each provided a plurality of markings. On the one hand, the markings are so-called cut marks 6 . 7 . 8th as well as alignment marks 9 , The cut marks 6 . 7 . 8th and alignment marks 9 lie opposite each other. The opposite cut marks 6 and the opposing cut marks 7 define a section of paper 10 on which is a decorative picture 13 located.
  • The cut marks 6 . 7 serve here as a display for dividing the printing paper web into individual sheets. The alignment marks are used in this context for 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 five identical decor sections 14 has, which are pressed in the further processing with plate-shaped bodies to flat 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 can also be a larger or smaller number of decor sections per decorative image 13 be provided.
  • In the illustrated embodiment, it is now so that the individual cut marks 6 . 7 . 8th are arranged at different distances from each other. The usual distance between two cut marks, and thus the usual amount of paper cut through the cut marks, is determined by the distance between adjacent cut marks 6 . 7 determined at a border area. The distance of the cut marks 7 and 8th is significantly less than the distance of the cut marks 6 . 7 , The distance of the cut mark 8th to no longer dargestell but in the longitudinal direction following cut mark ultimately again corresponds to the distance of the cut marks 6 . 7 ,
  • The procedure for printing on the printing paper 1 Now takes place such that the printing paper 1 from a teaching paper roll to a digital printing device. This can be an ink-jet printer, through which the decor 2 is printed. Before printing begins, the printing paper becomes 1 from the blank paper roll passed through a corresponding paper feed of the digital printing device to a Papierabführung on which the printing paper 1 is wound up. Then you can start printing. For example, to print the decor image 13 first on both sides the cut mark 6 printed. At the same time, the decorative image is on the printheads, which are located on the movable on a printer guide printer carriage 13 printed. After in the meantime the alignment marks 9 have been printed, become the end of the decor image 13 the cut marks 7 printed. The cut marks 7 on the one hand form the end of the paper section 10 and the beginning of the paper section 11 with a corresponding decor image 13 ,
  • Here are the individual decor images 13 on the paper sections 10 . 11 . 12 identical. However, this does not have to be the case. Basically, you can also use different decor images 13 on the individual paper sections 10 . 11 . 12 be provided.
  • During the printing of the decor image 13 on the paper section 11 Now the printing process is 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 supervised. This is an automatic monitoring by means of a monitoring device, not shown in detail. If the visual inspection after the resumption of the printing operation determines that the print quality of the decorative image 13 according to the specified requirements, the cut marks become 8th printed. The cut marks 8th limit the paper section 11 and set the beginning of the paper section 12 with a new decor image 13 represents.
  • For monitoring the print quality, the optical monitoring device has at least one optical sensor 15 . 16 on. In the illustrated embodiment, the optical sensor 15 directly on the decor image 13 directed while the optical sensor 16 on a marginal strip marker 17 directed, which is parallel to the decor 2 runs along the edge and parallel and at the same time to the decorative images 13 is printed. The edge trim mark 17 in this case has a plurality of edge strips 18 on. The individual margins 18 are colored and correspond to the printing device in terms of their color and number of colors and number of active printheads.
  • The two sensors 15 . 16 , which are arranged immediately after the printer carriage or the printheads can be provided alternatively or together. In any case, the two sensors 15 . 16 ultimately with a control device 19 the printing device 1 coupled, which in turn has a comparator, not shown, in which in an actual-target comparison, the current print result is compared with the predetermined target pressure result.
