Definitions

  • the present invention relates to a method and an apparatus for producing a decorative surface.
  • a decorative surface for furniture, floor panels or wall panels is state of the art.
  • Surfaces of workpieces e.g. Particle board or MDF board, coated with a decorative printed paper or printed directly after applying a white primer and provided with a protective lacquer.
  • the surfaces are often replicas of real wooden surfaces, stones or tiles. Both the image (decor) of the wooden surface and the tactile "haptic" structure (tactile wood pores and knotholes) are reproduced.
  • the surfaces that are coated can (also in the sense of the present invention) also be rolled goods such as printed paper or printed plastic films.
  • the optical replication of decorative images is generated both with analog printing methods and with digital printing methods based on a digital image template.
  • an analogous method is used according to the prior art, such as embossing with structured embossing plates (“matrices”). It is also known to generate such structures with digital methods, as is the case in DE 10 2015 110 236 A1 and DE 10 2009 044 802 A1 is shown.
  • the DE 10 2007 055 053 A1 discloses a method for processing a structured surface of an embossing tool ("die"), wherein the degree of gloss of a first coating differs from that of a second coating, for example to better emulate wood pores.
  • die embossing tool
  • the degree of gloss of a first coating differs from that of a second coating, for example to better emulate wood pores.
  • an embossing tool for producing a finished product for example one Floor panels, consisting of an HDF core board and a printed, melamine-impregnated paper as a decorative layer
  • the wood pores printed decoratively in the paper also by differences in gloss level of the hardened melamine surface, molded from the differently machined surface of the die, visible.
  • embossing tool is a complex process.
  • embossing tools are mostly used in short-cycle presses in which the change from one embossing tool to the other takes a long time, at least about 15-30 minutes.
  • the WO 2006/037 644 A2 discloses a method and an apparatus for producing a structured surface.
  • a first coating of lacquer is applied to the surface of the workpiece.
  • a second coating of lacquer is then applied to the first coating with a spatially varying distribution of the application quantity.
  • the WO 2010/079 014 A2 finally discloses a component made of a wood-based material with printed decor and different degrees of gloss and a structured top coat layer.
  • a workpiece that is coated with at least one first lacquer layer is first fed to a digital printing station, at which digital control data are provided, which are at least partially related to a optionally available decorative image can be coordinated on the workpiece. Then droplets are digitally sprayed onto partial areas of the first lacquer layer on the workpiece with an at least partially transparent lacquer for applying a second lacquer layer on the first lacquer layer, the second lacquer layer having a different degree of gloss after curing than the first lacquer layer.
  • the second layer of lacquer provides the surface of the workpiece with different degrees of gloss, so that the degree of gloss can preferably be adapted to the optional underlying decorative image.
  • the degree of gloss on the surface can be individually adjusted depending on the digital print template, successive workpieces with a different degree of gloss can be printed at different locations without the need to replace a die or another tool.
  • the workpiece is preferably first fed to a device for coating and coated with at least one first layer of paint.
  • the workpiece is then preferably fed to the digital printing station.
  • the degree of gloss of the first lacquer layer preferably deviates by at least 10 gloss units, preferably at least 20 gloss units, from the degree of gloss of the second lacquer layer, the gloss units being measured at an angle of 60 ° in accordance with DIN EN ISO 2813: 2015-02. This makes an optically clearly perceptible gloss effect recognizable.
  • the setting of the degree of gloss can be varied during printing by the droplet size and / or the number of droplets per surface or by the use of matting agents.
  • the gloss measurement is carried out in accordance with DIN EN ISO 2813: 2015-02.
  • the unit of measurement used is GU (Gloss Units).
  • the amount of light reflected on the surface depends on the angle of incidence and the properties of the surface.
  • different angles of incidence (20 °, 60 ° and 85 °) can be used to determine the degree of reflection, preferably measuring with the angle of incidence of 60 °.
  • the mean value of measurements at the three angles of incidence can also be used.
  • the reflectance compares the light energy emitted and received by a gloss meter in percent at a certain angle of incidence.
  • All surfaces or sections of surfaces that achieve less than 20 gloss units when measured with a gloss level meter are defined as “matte” and all surfaces or sections of surfaces that achieve more than 60 gloss units are defined as “glossy” designated.
  • One of the two layers of paint can be matt and the other glossy.
  • the surfaces on the first and second lacquer layers can be smooth or structured.
  • a structured surface the gloss measurement and the definition of the distinction between “matt” and “glossy” partial areas used here are carried out in exactly the same way as in the case of non-structured surfaces.
  • a structured surface of the workpiece can, for example, have a structure depth of 5-300 ⁇ m (micrometers), preferably 10-90 ⁇ m (micrometers).
  • the droplets of the second lacquer layer are sprayed on with a droplet size preferably less than 100 pL, in particular less than 10 pL.
  • Different gloss levels can optionally also be set on the second lacquer layer, so that there may also be gloss differences within the second lacquer layer.
  • a colored decorative image can be printed using the analog process, for example using printing rollers, or by means of digital print heads.
  • a transparent lacquer layer can be applied to an existing decor image with the first lacquer layer.
  • a liquid base layer is applied to a surface of a coated or uncoated workpiece and a structure is introduced into the still liquid base layer by means of digital print heads, in order to then subsequently close the structured base layer fix.
  • the structured base layer can then optionally form the first lacquer layer or it then becomes a first layer of lacquer is applied to the structured base layer.
  • only the areas provided with a structure or only the areas without structure can be printed with the second lacquer layer. This allows an essentially congruent arrangement of structured areas and shiny or matt areas.
  • FIG. 1 A plate-shaped workpiece 1.0 is shown, on which an optional first base layer 1.1 is applied to a surface.
  • a decorative image for example a wood reproduction or a tile representation, is optionally printed on the workpiece 1.0 before the first base layer 1.1 is applied.
  • a decorative image can also be printed after the application of the first base layer 1.1 or after the application of a (structured) second base layer 1.2, for example using a 4-color digital printer.
  • a second liquid base layer 1.2 is applied to the first base layer 1.1. This second base layer 1.2 has been structured by digitally sprayed-on droplets 1.3, so that the surface is no longer flat but has a structure.
  • a first lacquer layer 1.4 is then applied, which has a first degree of gloss.
  • a second lacquer layer 1.5 is applied to the first lacquer layer 1.4 via digital print heads, the second lacquer layer 1.5 being the surface of the first Paint layer 1.4 only partially covered.
  • the lacquer layers 1.4 and 1.5 are cured in succession or together, for example using UV radiation. After curing, the second lacquer layer 1.5 has a different degree of gloss than the first lacquer layer.
  • Figure 2 is a plan view of the plate-shaped workpiece 1.0 of the Figure 1 shown and it can be seen that the decorative image comprises a wood pore 2.5 and grained wood areas 2.4.
  • the different areas of the wood pore 2.5 and the grained wood areas 2.4 can also have a different degree of gloss due to the second lacquer view 1.5, the decorative areas of the image and the different gloss areas due to the lacquer application preferably being congruent.
  • a carrier plate made of a wood-based material or a plate made of another material with a thickness of at least 4 mm, preferably 8 to 16 mm and external dimensions of at least 200 mm width and at least 400 mm length is initially coated with a UV-curing agent , white base coat coated, for example with an amount of about 20 g / sqm. This white base coat is then cured under UV radiation.
  • the carrier plate is then fed to a digital printing device, in which a printed image, for example a replica of small tiles as a mosaic, a wood decor or another pattern, is applied using 4-color printing as CMYK.
  • a digital printing device in which a printed image, for example a replica of small tiles as a mosaic, a wood decor or another pattern, is applied using 4-color printing as CMYK.
  • FIG. 3 a sample with two differently colored mosaic tiles is shown as an example for a printed image, light mosaic tiles 3.1 and darker mosaic tiles 3.2 being provided.
  • a variety of other colors of tiles or mosaics with pictorial representations can be used.
  • a thin base coat layer of 5-15 g / sqm of a likewise UV-curing lacquer is applied to the carrier plate printed in this way and (partially) cured with UV light.
  • this base lacquer layer can also be dispensed with entirely, or replaced by a solvent-based lacquer or an aqueous acrylate lacquer, which is then physically dried.
  • a further base lacquer layer 1.2 is then applied to the first base lacquer layer or alternatively directly to the printed image as a radiation-hardening lacquer layer, preferably on an acrylate basis, in a layer thickness of 10-100 ⁇ m. Both layers of basecoat can be applied by digital printheads or by pressure rollers or other methods.
  • a further, transparent lacquer layer 1.3 is optionally printed into the still liquid layer using a digital printing template with digital print heads. When this lacquer layer 1.3 is applied, the droplet size can vary between 1 pL and 100 pL.
  • the digital print template used is the one that was also used to print the tile mosaic described above.
  • This template is previously electronically modified so that only the spaces 3.3 of the mosaic tiles 3.1 and 3.2 are printed.
  • the radiation-curing base lacquer layer 1.2 is then cured together with the lacquer layer 1.3 using a UV lamp.
  • curing can also take place by means of electron radiation.
  • the result is a support plate printed with a tile mosaic, in which the interspaces 3.3 are deepened by 10 - 60 ⁇ m as joints between the mosaic tiles 3.1 and 3.2.
  • the degree of gloss of at least parts of the entire surface is then adjusted to the desired value by the at least partial application of a first lacquer layer 1.4 with subsequent drying, the degree of gloss of the lacquer layer 1.3 deviating from the gloss degree of the second lacquer layer.
  • a second lacquer layer 1.5 will also be carried out before or after the hardening of the first lacquer layer 1.4, the second lacquer layer 1.5 likewise consisting of a large number of droplets with a size of 3-100 pL released onto the surface.
  • the degree of gloss in partial areas can be changed again, and the surface structure depth of the not yet hardened first lacquer layer 1.4 can be influenced.
  • the surface of the mosaic tiles 3.1 and 3.2 now has a value of, for example, 60 to 90 gloss units, while the degree of gloss at the spaces 3.3 is, for example, only 20 to 40 gloss units.
  • the degree of gloss at the gaps 3.3 can also be reduced by a further layer of lacquer, which is then printed by a further digital printing device with a transparent, UV-curing lacquer in the lowered gaps. Then more than just two layers of lacquer are applied to adjust the degree of gloss.
  • Droplet sizes of 3 - 6 pL are used to print a more matt lacquer layer, which are cured within 0.5 - 2 seconds after hitting the surface with UV-LED radiation to such an extent that they can no longer flow. This creates a surface structure in these areas the incident light no longer reflects. The degree of gloss is thus reduced to values of 30 gloss units and less.
  • the second lacquer layer can optionally have a higher or lower degree of gloss than the first lacquer layer.
  • the degree of gloss can be set using the following methods, for example:
  • Matt areas through the first layer of lacquer consist of previously applied (analog or digital) matt lacquer, for example with matting agents or by excimer matting.
  • Glossy areas of the second lacquer layer consist of lacquer applied by digital printheads, which is formed from a large number of individual droplets, which results in a section which is very smooth in sections and thus a high degree of gloss.
  • the droplets have a size of at least 6 pL, and curing takes place only after a development phase of at least 1 sec, preferably only after more than 5 sec.
  • the glossy areas of the first lacquer layer consist of previously applied (analog or digital) glossy lacquer, matt areas of the second lacquer layer consist of digitally applied lacquer from a multitude of tiny droplets with a droplet size of less than 8 pL, preferably less than 3 pL, which are within less than 3 sec after application, preferably less than 1 sec after application, are at least partially cured.
  • curing is preferably carried out by means of a UV-LED lamp which is arranged in the direction of passage within less than 100 mm after the digital printheads which apply the large number of droplets to the surface.
  • Matting agents for example PE waxes or silicas, can be added to the lacquer to produce a matt lacquer layer.
  • the proportion of matting agents in the paint can be between 2% to 6%, in particular 3% to 5% (weight percent).
  • the lacquers used can be replaced by aqueous or solvent-based lacquers instead of acrylate-containing, UV-hardening lacquers.
  • the steps for UV drying using UV LEDs or UV arc lamps are replaced by physical drying using hot air or IR radiators or a combination of both.
