Definitions

  • the invention relates to a method for producing a surface with gloss differences on a plate-shaped workpiece according to the preamble of patent claim 1, a plate-shaped workpiece with a surface with gloss differences according to the preamble of claim 7 and a system for generating a surface with gloss differences on a plate-shaped workpiece the preamble of claim 11.
  • a carrier plate in particular a wooden material carrier plate is first printed with a decorative layer.
  • a decorative layer can be a monochrome lacquer layer, but often a wood decor for imitating a natural wood surface, a decorative print for imitating a stone surface, a decorative print with artistic motifs and the like are also used more often. This is also the case in the context of the present invention.
  • sealing layer is applied over this entire area to this decorative layer, wherein the sealing layer consists of a sealing lacquer which has a first degree of gloss after it has cured.
  • This may in particular be a transparent gloss varnish or else a translucent matt varnish. This is depending on the desired optical effect in conjunction with the decorative layer freely selectable.
  • the sealing layer After the sealing layer is at least partially cured, it is conventionally printed directly with a design print which is formed with an at least partially transparent design varnish, which has a second degree of gloss after it has cured.
  • the interaction of the different degrees of gloss of the design print and the sealing layer is generally used to visually approximate a plate-shaped workpiece with a decorative layer that mimics the natural surface of wood or other natural material, because the sealing layer, the decorative layer Protects against abrasion, in particular causes an artificial appearance of the surface, if the surface has a uniform gloss level.
  • the natural pores of a wooden surface of such on the surface of the sealing layer optically and haptically reproducible that the design pressure at those points where the decorative layer depicts a wooden pore, which actually means a depression in the wood surface, a Three-dimensionally raised paint application takes place, which interrupts the gloss of the sealing layer at this point and is also haptic perceptible.
  • the present invention is based on the approach of varying the uniform gloss level of the sealant layer by imprinting a design print without pursuing the goal of providing the design print with perceptible three-dimensional characteristics.
  • the resulting surface which is formed in part by the print image of the design print and partly by the exposed surface of the sealant layer, may also lack three-dimensional structures of varying gloss be provided.
  • the simple imprinting of a design printing offers the advantage over the known impressing of a structure in the sealing layer as well as with respect to the known application of a three-dimensional structure the advantage of a much easier handling, since usual and decades-proven printing techniques can be used.
  • large variations in the gloss level of the surface of the plate-shaped workpiece can be produced without spending correspondingly high amounts of textured paint for the formation of a three-dimensional structure to have, in addition, requires an extremely long time or a high energy expenditure for curing.
  • the present invention is therefore based on the object, a method of the type mentioned above and a plate-shaped workpiece and a machine of the type mentioned in such a way that surfaces with particularly high gloss degrees differences or gloss level jumps can be produced.
  • the inventive method is accordingly modified by the fact that after the at least partial curing of the sealing layer, an at least partially transparent intermediate layer is applied over the entire surface of the sealing layer, and that the design varnish is wet-on-wet printed on the intermediate layer prior to curing of this intermediate layer.
  • the intermediate layer is in this case produced with an intermediate lacquer which consists of the same material as the sealing lacquer, or else of a material which after curing has a degree of gloss similar to that of the sealing lacquer.
  • the plate-shaped workpiece thus produced has a surface which has a second degree of gloss within the printed image of the design print and a first gloss level of the sealing layer outside the print image of the design print, these two gloss levels, measured according to DIN EN ISO 2813 at an angle of 60 ° at least 50 gloss units (GU), preferably differ by at least 70 GU.
  • the system according to the invention for producing a surface with gloss differences on a plate-shaped workpiece is accordingly modified according to the invention in that between a hardening device and the printing device for the design printing a Swisslackier worn for full-surface application of an at least partially transparent intermediate layer is disposed on the sealing layer, wherein the intermediate layer with a Intermediate varnish is made, which consists of the same material as the sealing varnish or of a material which has a similar gloss level after its curing as the sealing varnish.
  • the printing device and the intermediate coating device are also configured in accordance with the invention in such a way that the design coating is printed on the intermediate layer wet-on-wet before the intermediate layer is cured.
  • this residual film significantly changes the degree of gloss of the sealing layer, namely in the direction of the gloss level of the desing lacquer. This reduces the gloss level difference between the gloss level of the design lacquer prevailing in the print image of the design print and the gloss level outside the print image, which is then no longer the gloss level of the sealer because of the residual film, but has changed towards the gloss level of the design lacquer.
  • the effect of the residual film is particularly disturbing if a sealing layer with a particularly high degree of gloss is used and then a design print with a lower degree of gloss is printed on it. Even if the gloss level of the design pressure is only slightly lower than the gloss level of the sealant layer, the gloss level of the sealant layer is lowered by the residual film. The same can be observed when a sealing layer with a particularly low gloss level is used and then a design print is printed with only a slightly higher gloss level.
  • the cause of the sometimes unsatisfactory gloss level jumps in the surface of a plate-shaped workpiece of the present type which has come to light through these findings according to the invention, is rendered harmless by the fact that the design print is not directly printed on the at least partially hardened sealing layer, but rather an intermediate layer onto which it is wet -in-wet, before curing the interlayer, the design varnish is printed.
  • the intermediate lacquer for producing this full-surface intermediate layer may comprise an additional layer of the sealing lacquer be, or a different from this intermediate varnish, which has a similar gloss level after its curing as the sealing varnish.
  • the layer thickness of the intermediate layer When the layer thickness of the intermediate layer is appropriately selected, the inevitable residual film of design varnish applied to the surface of the work outside the actual print image of the design print is taken up by the still wet interlayer, so that it has the gloss level after curing Sealing varnish not or only insignificantly changed.
  • the application quantity of the intermediate layer should be chosen such that the design varnish in the actual printed image, despite the wet-on-wet printing, mixes only insignificantly with the intermediate layer and in particular remains substantially unaffected on its surface, ie after curing, its typical, having substantially unadulterated gloss.
  • the surface-specific application quantity of the design lacquer in the printed image should typically correspond to at least 1.5 times, preferably 1.5 to 15 times, the area-specific application quantity of the intermediate layer.
  • the area-specific application quantity of the intermediate layer ie the amount of material of the intermediate paint applied per unit area, should be at least 5 times, preferably 5 to 50 times the area-specific application quantity of the residual film of the design paint printed outside the printed image of the design print correspond.
  • the application rate of the (actually unwanted) residual film is so significant that it can be measured.
  • This measure according to the invention makes it possible, with a method of the present type, to produce a plate-shaped workpiece having a carrier plate, a decorative layer, an at least partially transparent sealing layer and an at least partially transparent design printing applied thereto, in which between the printed image of the design print and the remaining surface a gloss level difference of at least 50 gloss units (GU), preferably of at least 70 GU is formed, measured according to DIN EN ISO 2813 at an angle of 60 ° and at a distance of 20 mm.
  • GU gloss units
  • DIN EN ISO 2813 at an angle of 60 ° and at a distance of 20 mm.
  • the print image of the design print may have a higher gloss level than the surface of the sealant layer or the intermediate layer; however, in the context of the present invention it may also be reversed, i. the sealing layer is formed, for example, from a transparent high-gloss lacquer, wherein the printed image of the design pressure has a matte surface.
  • a sealing varnish and a design varnish can be used whose gloss levels, measured according to DIN EN ISO 2813 at an angle of 60 °, in the respectively cured state differ by at least 50 gloss units (GU), preferably by at least 70 GU.
  • the present invention also offers advantages when a high gloss finish sealant, preferably above 75 GU, is used and the design print has a slightly lower gloss level. Because of the intermediate layer used according to the invention, no or hardly any degree of gloss change of the surface takes place in the case of the sealing layer when printing with the design lacquer.
  • the sealant layer is gelled prior to the application of the intermediate layer, or is already substantially cured.
  • the hardened sealing layer is ground before the application of the intermediate layer in order to ensure a good adhesion of the different paint layers to one another.
  • a system is used with a printing device for printing the design printing, which performs an indirect gravure printing and comprises a gravure roll and a transfer cylinder, in particular a blanket cylinder.
  • a gravure roll is equipped with a doctor blade which scraps off excess design varnish
  • the blanket cylinder has a doctor blade, which scrape off the blanket cylinder to avoid ghosting during further circulations after transferring the printed image.
  • the blanket cylinder is preferably rinsed with design lacquer before being doctored off.
  • FIG. 1 shows a schematic, not to scale sectional view of a printed plate-shaped workpiece according to the invention. This is composed of a carrier plate 1 made of wood-based material, a base structure 2 applied thereto, a decorative layer 3, a sealing layer 4, an intermediate layer 5 and a design pressure 6.
  • the support plate 1 is made of a fiberboard laminated with a base structure 2 made of a melamine resin-impregnated adhesive paper which increases the resistance to indentations.
  • the decorative layer 3 is a color print of an image of a sawn wooden surface, in which case basically all possible prints can be applied, such as geometric shapes, artistic representations, or even a monochrome lacquer layer.
  • the design print 6 does not correspond to the appearance of the decorative layer 3, but forms an artistic pattern independent of it; as FIG. 2 shows, these are Blumeranken.
  • the design varnish used for the design print 6 is a matt varnish, which after curing has a gloss level of approx. 10 GU. This is in contrast to the sealing varnish, which forms the sealing layer 4: This is a gloss varnish, which has a degree of gloss of about 90 GU after its curing.
  • the intermediate layer 5, which consists of an additional layer of the same sealing varnish, and to which the design print 6 was applied wet-on-wet in accordance with the invention, has the design print 6 unavoidable in design printing Printed image 7 applied to the intermediate layer 5 residual film of design varnish recorded so that the visible outside of the print image 7 surface of the intermediate layer 5 after curing has a virtually unchanged gloss level of about 90 GU.
  • a final measurement showed a gloss level of about 10 GU in the printed image and a gloss level of about 86 GU outside the printed image.
  • a comparative measurement was carried out by preparing a wood-base plate with basic structure and decorative layer with the same materials and in the same manner, after which the same sealing lacquer was applied over the entire surface and cured.
  • a gloss level measurement according to DIN EN ISO 2813 at an angle of 60 ° and at a distance of 20 mm resulted in a gloss level of about 86 GU.
  • the residual film of design lacquer printed on the sealing layer outside the printed image of the design print decisively changed the gloss level of the surface: the comparative measurement resulted in a gloss level outside the printed image of the design print of only 57 GU. Optimization efforts by truer engagement of the two squeegees in the printing device used to apply the design print to minimize the area-specific application amount of the residual film, optimally yielded gloss levels outside the print image of the design print of 64 to 68 GU.
  • FIG. 3 shows a schematic side sectional view of an embodiment of a system that is designed according to the invention and for the production of the in the FIGS. 1 and 2 shown workpiece serves.
  • This system comprises a feed device for the carrier plate 1, wherein the feed device is not shown here, but merely by means of a conveyor 8 and the visualized conveying direction 9 is symbolized. Since the system processes the carrier plate 1 in line with the finished workpiece, a plurality of conveyors 8 are shown one behind the other in the conveying direction 9.
  • the plant comprises a decorative printing device 10, a sealing device 11, a hardening device 12, an intermediate coating device 13, a printing device 14 and a curing device 15, which are successively traversed by the workpiece.
  • the carrier plate 1 is printed with the decorative layer 3.
  • the sealing device 11 the sealing layer is applied over the entire surface of the workpiece, after which it is gelatinized in the curing device 12 by means of UV radiation.
  • the workpiece passes through the intermediate painting device 13, where according to the invention the intermediate layer 5 is applied to the entire surface of the sealing layer.
  • the design varnish is then printed wet-on-wet onto the intermediate layer 5.
  • the printing device 14 is shown enlarged in FIG.
  • the printing device 14 consists of a gravure cylinder 16 and a transfer cylinder 17, wherein the transfer cylinder 17 is designed as a blanket cylinder.
  • a moving in the conveying direction 9 on the conveyor 8 workpiece is printed by the transfer cylinder 17.
  • Both the gravure roller 16 and the transfer cylinder 17 have scrapers 18, 19 attached, each forming a reservoir for design lacquer 20.
  • the doctor blade 18 ensures that design lacquer 20 is coated in the depressions of the gravure roll and stripped off the roll surface outside the depressions.
  • the reservoir formed by the doctor 19 there serves to rinse the surface of the transfer cylinder 17 with design varnish 20.
  • the squeegee 19 ensures that as little design ink as possible remains on the surface of the transfer cylinder 18 after the rinsing process - except for the unavoidable residual film which according to the invention was identified as problematic and whose adverse effects were eliminated according to the invention.
