Definitions

  • Such methods have long been known from the prior art and are used to produce different decorative components. These include, for example, laminate panels that can be used as floor coverings or as wall or ceiling cladding, as well as panel-shaped decorative components that are used, for example, to produce furniture or other objects.
  • the printing material is a paper web that is printed with the desired decor.
  • the printing material is connected to the core, for example by pressing, and then divided up together with the core, so that the desired decorative components are produced.
  • a decorative component consequently has smaller dimensions than the core to which the printed substrate is connected. Accordingly, the decoration is larger than the decorative component.
  • the decor contains several, for example 8, 10 or 12 individual decors, corresponding to the same number of decorative components. Each decorative component is therefore provided with an individual decoration.
  • Paper webs are usually printed with a decor for the production of laminate panels that serve as floor panels. This is often done using pressure rollers, for example in rotary printing.
  • the dimensions of the pressure roller have an upper limit, since an increase in the pressure roller also results in an increase in weight. Therefore, the print length, which is given by the circumference of the print roller and which corresponds to the decor length, is also limited.
  • the surface area of the lateral surface of the pressure roller corresponds to the pressure area, and thus to the area of the decoration that can be used for the decorative components.
  • substrates are also printed with digital printing systems that no longer have a printing roller.
  • the decor that is printed on the printing material is contained in a print file, which also usually contains control commands and print parameters that are transferred to the digital printing system.
  • the dimensions of the decor contained correspond to those known from roller printing or rotary printing.
  • a first decor is first printed in a predetermined display, so that a first set of decorative components is produced in precisely this predetermined number.
  • a second set of decor components is then printed by printing a second decor also in a predetermined display and mixing the resulting decor components with the decor components with the first decor. This is complex and time-consuming and cost-intensive.
  • the invention is therefore based on the object of further developing a method for producing decorative components in such a way that a greater variety of decorations can be achieved.
  • the invention solves the problem set by a method according to the preamble of claim 1, which is characterized in that the decorative length is at least as long as two decorative components.
  • the decorative length is preferably at least as long as three, preferably four, particularly preferably six decorative components.
  • the invention is based on the finding that the limitation of the size of the decoration originating from rotary printing does not exist, or at least does not exist to such an extent, in a digital printing system.
  • the size of the decoration contained in the print file and transferred to the digital printing system is essentially limited by the maximum size of the print file that can be processed and handled by the electrical controller, for example an electronic data processing device, of the digital printing system.
  • the decor length is preferably greater than the decor width.
  • the length of the decorative components is preferably greater than the width of the decorative components.
  • the decor is preferably stored electronically in a print file that is transferred to the digital printing system and used to control the digital printing system.
  • the decor is divided into several such print files, which are transferred to the digital printing system and used to control the digital printing system.
  • the multiple print files are used together to control the digital printing system. It is not intended that initially the part of the decor that is stored in a first print file in a predetermined display is printed before another part of the decor stored in a second print file is printed. If the decor is divided into several print files, these corresponding parts of the decor are printed one after the other.
  • the part of the decoration that is stored in the first print file is preferably printed once first.
  • the part of the decor that is saved in a second print file is then printed once. This continues until each part of the decor has been printed once. This procedure is then repeated.
  • the decorative length is preferably at least as long as two, preferably as long as three, particularly preferably as long as four cores.
  • the length of the core is as long as two, more preferably as long as three decorative components.
  • the printing material is printed with a number of decorations that differ from one another.
  • Each of these decors then corresponds, for example, to a partial decor and is preferably stored in a separate print file that is transferred to the digital printing system.
  • the different print files are transferred in such a way that they can be used together to control the digital printing system.
  • the printing material is preferably a paper web.
  • This is usually provided as a paper roll and used as an "endless" paper web.
  • the paper web can also be provided in the form of individual sheets of paper, with the length of a sheet of paper preferably corresponding to the length of the decoration. This also applies if the decor consists of several part decors. As an alternative to this, it can be advantageous, particularly when using individual sheets of paper, if the length of a sheet of paper corresponds to the length of a piece of decoration.
  • the decorative components produced by the methods described herein are preferably laminate panels.
  • the printed substrate particularly preferably the printed paper web, is preferably Further processing impregnated and cut to create printed and impregnated decor paper sheets that form the decor sheets for further processing.
  • the decorative components are packaged in packages in such a way that only different decorative components are contained within a package.
  • the decorative components for example as floor panels, it is then ensured that the decorative components combined and packaged in a package do not lead to a repetition of the individual decoration.
  • the decorative components produced are particularly preferably packaged in a plurality of packages which contain different decorative components in pairs.
  • Each of the decoration components has a single decoration that is part of the decoration. If two packages contain different decor components in pairs, this means that the individual decors of the decor components of the first package do not appear on the decor components of the second package and vice versa. This configuration ensures that the use of the decorative components from the plurality of packs does not lead to a repetition of the motif.
  • the plurality of packets is preferably at least four, preferably at least six, particularly preferably at least ten packets.
  • the decoration is preferably enlarged by adding digital master patterns, so that the decoration length increases.
  • Digital image processing and digital image editing make it possible to change the decor afterwards and increase the length of the decor. This was impossible with roller printing or rotary printing. If, for example, further individual decors are to be added to the decor, additional original samples, such as real wood samples, are digitally recorded and mapped. These digital images are then added to the digital decor, i.e. the decor is enlarged.
  • the length of the decoration then no longer corresponds, for example, to the length of four decoration components, but to the length of five decoration components.
  • the decorative components preferably have a length of at least 100 cm, preferably at least 115 cm, particularly preferably at least 130 cm and at most 280 cm, preferably at most 200 cm, particularly preferably at most 150 cm.
  • the method takes the following form: First, the decor is digitized, for example by creating digital data. A scan or a photo of a motif, for example a real wood decor, a real stone decor or another decor can be generated. In principle, the amount of digital images produced in this way is only limited by the amount of memory that can be handled and processed by the electrical control system.
  • the actual decor is then created using image processing software by combining several digital images and merging them into one decor. The print width is determined by the width of the decor created in this way.
  • the print data length may be limited by the amount of data transferred or the file size. For example, with a pdf file and a length of 5080mm, it can be 1,080,000,000 data points. Up to this limit, which can vary greatly depending on the electrical control and digital printing system, the variety of individual decors can be further increased. In principle, it is also possible to increase the diversity of these individual decors. A number of print files containing partial decors are then used, which are numbered 1, 2, 3, for example. These are then preferably printed in the order 1,2,3,1,2,3,1,2,3.
  • the decor which is transferred to the electrical control of the digital printing system in one or more print files, does not have to be printed completely.
  • only a section of the transferred decor is printed, with the section being almost freely selectable. The only important thing is that the printed section is large enough that all the decorative components produced are over have a single decor. This also makes it possible to avoid motif repetition and increase the variety of individual decors almost indefinitely.
  • the decor that is transferred to the digital printing system can be stored in one or more files, with the partial decors contained in each case being able to be printed endlessly and without visible transitions.
  • an edge can be present in the printed image, for example depending on the dimensions, in particular the length, of the decorative components to be produced. For example, if floor laminate panels are produced with a length of 140 cm, there is an edge in the printed image at a distance of 140 cm.
  • the decor can also contain control characters or quality defects that are placed in the print data or during printing and that are read out during further processing and are helpful for assigning the individual decor components and sorting them into packaging units.
  • the print width is 205cm.
  • the maximum print area which can also be referred to as the decor variety area, is 186cm x 205cm (approx. 3.8m 2 ) and corresponds to 10 floorboards, for example.
  • an oak decor in the collection which should grow in its variety of planks every year.
  • a lot of different natural material has already been provided for digitization.
  • two partial decors, each with a length of 372 cm each, i.e. a total of 744 cm, of this decor are created.
  • the variety of decor increases by another 3.8 m 2 every year.
  • the variety of decors is the area that can be covered with floor panels of this decor without repeating the decor.
  • the standard printing width for decors in industrial floorboard production is “only” about 1400 mm. At one manufacturer, all decors were previously printed using rotary printing with a roller circumference of 1300mm. The print area, i.e. the variety of decors, of 140cm x 130cm corresponded to seven individual floorboards.
  • a wood decor is produced on a digital paper printing system with a working width of 2070 mm and a paper speed of 135 m/min.
  • the paper is a decorative paper white with a grammage of 65g and a water-based ink is used.
  • the color system corresponds to the CRYK system.
  • a primer is applied inline in an amount of 3 g/m 2 .
  • the wood decor has a print length of 4200mm and a width of 2070mm.
  • the resulting laminate plank after further processing is 1400 mm x 193 mm. Accordingly, there is a variety of 30 different planks for this decor.
  • each plank is given a number from 1 to 30, which is embedded in the separations using software in such a way that it is not visible to the human eye, but can be recognized by optical measuring devices and image recognition software.
  • the pack size in this embodiment is 10 planks per pack.
  • figure 1 The schematic sequence of a method according to an embodiment of the present invention.
  • FIG. 1 shows schematically the course of a method of the type described here.
  • a scan template 2 is used, from which digital images are to be generated.
  • a scanner 4 is used for this purpose.
  • a digital image is thus created of each element of the scan original 2 .
  • an electrical controller 6 which in the exemplary embodiment shown is a computer, in particular a laptop.
  • the decor 8 has a plurality of individual decors 10, three of which are shown side by side and ten one above the other in the exemplary embodiment shown. They correspond in size and shape to the decorative components to be produced.
  • markings 12 which are designed as circles, squares and triangles in the exemplary embodiment shown.
  • the type of marking 12 encodes whether the respective decorative component to be produced was provided with an individual decoration from the left (circle), the middle (square) or the right (triangle) area.
  • the position of the respective marking 12 shows the position of the individual decor in this area.
  • ten decorative components are combined into a container 14 and packaged. Through the markings 12 can ensure that only different individual decorations are present in a container 14 .
