METHOD AND SYSTEM FOR PRODUCING A MATERIAL BOARD

Abstract

A method for producing a material board, which has a structured, colored surface, assigns image data to a colored digital image of a colored original surface. The image data is used to produce a first image data set and at least one second image data set, which are each assigned to different color channels of the colored digital image. A colored surface is produced on a base carrier using the at least one second image data set but without using the first image data set. The colored surface of the base carrier is pressed by use of a structured pressing surface of a pressing tool, in order to obtain the material board with the structured, colored surface. The structured pressing surface is assigned to the first image data set.

Description

[0041] Exemplary embodiments of the invention are shown in the enclosed schematic figures by way of example. These show:

[0042] FIG. 1 a top view of a structured, colored original surface,

[0043] FIG. 2 a top view of a colored digital image of the structured, colored original surface,

[0044] FIG. 3 image data assigned to the colored digital image,

[0045] FIG. 4 a pressing plate with at least one structured pressing surface,

[0046] FIG. 5 a material board,

[0047] FIG. 6 a base material board, and

[0048] FIG. 7 a paper and a carrier.

[0049] FIG. 1 shows the top view of a structured, colored original surface 1, which in the case of the present exemplary embodiment is assigned to a natural wood pattern. The colored original surface 1 may also be flat.

[0050] The structured, colored original surface 1 in particular comprises a colored pattern 2 and a structure 3 formed by subjacent and raised areas in the original surface 1.

[0051] FIG. 2 shows a colored digital image 21 of the structured, colored original surface 1.

[0052] Image data 30 shown in FIG. 3 is assigned to the colored digital image 21.

[0053] A first image data set 31 and at least one second, in the case of the present exemplary embodiment multiple second, image data sets 32a, 32b are generated from the image data 30.

[0054] The first image data set 31 and the second image data sets 32a, 32b are each assigned to different color channels of the colored digital image 21.

[0055] The first image data set 31 is provided for the production of a pressing tool having a structured pressing surface. The pressing tool, for example, is a pressing plate 41 shown in FIG. 4 which comprises a structured pressing surface 42. The pressing tool may also be a pressing roller having a structured pressing surface or an endless belt having a structured pressing surface.

[0056] In the case of the present exemplary embodiment, the structured pressing surface 42 is assigned to the first image data set 31 and/or was produced using the first image data set 31 and without using the second image data set 32a, 32a. The first image data set 31 may be further processed, in particular be reduced such that, for example, a further processed first image data set 33 emerges, prior to the production of the pressing plate 41 and/or its structured pressing surface 42. In the case of the present exemplary embodiment, the further processed first image data set 33 is used for the production of the pressing plate 41 and/or its pressing surface 42.

[0057] The structured pressing surface 42 may have one single degree of gloss or multiple different degrees of gloss. The different degrees of gloss may be generated based on the first image data set 31 and/or the further processed first image data set 33.

[0058] The structured pressing surface 42 is provided for producing a material board 51, which comprises a structured, colored surface 52, shown in FIG. 5.

[0059] The material board 51 is, for example, made from a plastic material or comprises a wooden material board.

[0060] To obtain the structured, colored surface 52, for example, first, the relevant surface of a base material board 61 shown in FIG. 6 as an example of a base carrier is processed using the second image data sets 32 without using the first image data set 31, such that the base material board 61 obtains a colored surface 62. Optionally, the two second image data sets 32a, 32b are previously further processed, in particular further processed manually, such that further processed second image data sets 34a, 34b emerge which may be used for processing and/or printing onto the base material board 61.

[0061] To obtain the colored surface 62, for example, a digital color printer is used, or accordingly colored color printing rollers are used. Optionally, image data sets, which are suitable for controlling the digital color printer, can be automatically generated from the second image data sets 32a, 32b and/or the further processed second image data sets 34a, 34b.

[0062] Subsequently, in the case of the present exemplary embodiment, the colored surface 62 of the base material board 61 is provided with a resin or a plastic material film and is pressed with the pressing plate 41 and/or its structured pressing surface 42, such that the material board 51 with its structured, colored surface 52 emerges.

[0063] FIG. 7 shows a paper 71 with a colored surface 72 as a further example of a base carrier. To obtain the colored surface 72, the relevant surface of a paper was processed using the second image data sets 32 without using the first image data sets 31. Optionally, the two second image data sets 32a, 32b are previously further processed, in particular further processed manually, such that further processed second image data sets 34a, 34b emerge which may be used for processing and/or printing onto the paper 71.

[0064] To obtain the colored surface 72, for example, a digital color printer is used, or accordingly colored color printing rollers are used. Optionally, image data sets, which are suitable for controlling the digital color printer, can be automatically generated from the second image data sets 32a, 32b and/or the further processed second image data sets 34a, 34b.

[0065] To obtain the material board 51, in particular, the paper 71 is soaked in a resin and is subsequently pressed with a carrier 73 and using the pressing plate 41 and/or its structured pressing surface 42, such that the material board 51 with its structured, colored surface 52 emerges.

[0066] The carrier 73 is, for example, made from a plastic material or comprises a wooden material board.

[0067] In addition to the structured, colored surface 52, the material board 51 may comprise a further structured, colored surface. These two structured, colored surfaces are arranged opposite one another and are congruent. To obtain the further structured, colored surface, for example, two third image data sets may be generated from the two second image data sets (32a, 32) by axisymmetric mirroring of the two second image data sets (32a, 32). Subsequently, a further colored surface may be produced on the base carrier using the two third image data sets, wherein the colored surface and the further colored surface are congruent and arranged opposite one another.

[0068] The further colored surface of the base carrier is then, for example, pressed using a structured pressing surface of a further pressing tool, so as to obtain a material board with a further structured, colored surface.
