Specifically, the transparent cover layer 15 can give gloss or matte to the second ink layer 13b. Thereby, for example, when a tile is selected as an object, the texture of the tile can be expressed on the convex portion 12.

  The transparent cover layer 15 is formed by applying a transparent UV curable ink. The transparent UV curable ink is not particularly limited, and known ones can be appropriately employed. For example, an ink composed of a UV curable resin, a matte material, and an auxiliary agent can be used.

Next, the manufacturing method of an uneven | corrugated decorative board is demonstrated.
FIG. 3 is a flowchart showing a method for manufacturing the uneven decorative board according to the present embodiment.
As shown in FIG. 3, the manufacturing method of the uneven decorative board 1 according to the present embodiment reads the surface of an object having unevenness on the surface with a scanner and obtains image data in the first step S <b> 1 and the image data, Image processing is performed using a computer, and first correction data that is partitioned so that the difference between the concave portion 11 and the convex portion 12 becomes clear, and second correction data that is colored in the concave portion 11 and the convex portion 12 are created. A second step S2 to be performed, a third step S3 for forming the convex portion 12 by printing and curing the UV curable ink using an ink jet printer on the base 10 based on the first correction data, and the base 10, based on the second correction data, the ink layers 13 a and 13 b are formed by printing patterns on the upper surfaces of the concave portions 11 and the convex portions 12 using an ink jet printer, respectively. A fourth step S4, and a fifth step S5 of forming the transparent cover layer 15 by print a UV curable ink is cured using an inkjet printer on the upper surface of the ink layer 13b provided on the convex portion 12.

Hereinafter, each step will be described in more detail.
First, in the first step S1, the surface of an object such as natural stone, natural wood, tile or the like having irregularities on the surface is read with a full-color scanner to obtain image data.

FIG. 4 is a perspective view schematically showing a scanner used in the method for manufacturing an uneven decorative board according to this embodiment.
As shown in FIG. 4, in the first step S <b> 1, for example, when a tile T is used as an object, the surface of the tile T is read as image data by the scanner 50.
At this time, the scanner 50 is provided with an illumination 52 having a light source on the lower surface. The light is emitted from the illumination 52 and the tile T is slid so that the unevenness on the surface of the tile T is shaded. At that time , the surface is photographed by a camera 51 attached above the illumination 52 through a slit 53 provided in the illumination 52 . Thus, image data obtained, since shadows also photographed becomes Rukoto, after the step, it is possible to more sterically represent the difference in level between the concave 11 and the convex portion 12 of the uneven veneer.

  Next, in the second step S2, image processing is performed on the image data obtained in the first step S1 using a computer. Note that image processing can be appropriately performed using known software.

Fig.5 (a) is a top view which shows the 1st correction data at the time of using a tile as a target object in the manufacturing method of the uneven | corrugated decorative board which concerns on this embodiment, FIG.5 (b) is this embodiment. It is a top view which shows the 2nd correction data at the time of using a tile as a target object in the manufacturing method of the uneven | corrugated decorative board which concerns on.
As shown in FIG. 5A, in the first correction data, the portion that becomes the convex portion 12 is outlined and the portion that becomes the concave portion 11 is shown in black based on the image data. The section 12 is partitioned.
On the other hand, as shown in FIG. 5B, in the second correction data, the color is arranged in the concave portion 11 including the shaded portion and the convex portion 12 based on the image data.
At this time, the concave portion 11 and the convex portion 12 have different colors.
Further, the color is arranged so as to be dark (lightness is low) according to the depth of the concave portion 11, and the portion where the shadow can be formed is darker (lightness is low) than the other portions. Thereby, it becomes possible to visually recognize the level difference between the concave portion 11 and the convex portion 12 of the obtained uneven decorative plate more three-dimensionally.

And in 3rd step S3, based on 1st correction data, white UV curable ink is printed on the part used as the convex part 12 with respect to the base 10 using an inkjet printer. In addition, it does not print in the part used as the recessed part 11. FIG.
Thereby, the recessed part 11 and the convex part 12 are formed. At this time, by increasing the and print count changing the density of ink dots (the number of paths of the nozzles), it is possible to increase the height of the convex portion 12.

Here, as described above, the base 10 may be provided with a base material or a sealing material.
The method for applying the base material to the base 10 is not particularly limited. For example, a roll coater is used, and the method for applying the sealing material to the base 10 is not particularly limited. For example, a reverse coater is used. .
In addition, after giving a base material and a sealing material to the base 10, it is preferable to grind with sandpaper etc. and to provide a polishing stripe on the surface. In this case, since the contact area with the ink increases, the adhesion force of the ink increases.

In the method of the uneven decorative plate according to the present embodiment, the inkjet printer used is Ru Tei equipped with UV curing device.
Further, since the UV curable ink is discharged by the ink jet printer and then immediately cured by the UV curing device, the UV curable ink can be cured in a hemispherical state. If it does so, the edge part of the convex part 12 is roundish, and even if it is a straight part by the top view, it can be made into the straight line with exit / entrance. Accordingly, for example, when the object is a tile, it is possible to express a unique texture of an actual tile.

  Next, in 4th step S4, after performing 3rd step S3, based on 2nd correction data, a pattern is printed on the upper surface of the recessed part 11 and the convex part 12 using an inkjet printer, respectively. The first ink layer 13a and the second ink layer 13b are then formed.

  In the manufacturing method of the uneven decorative board according to the present embodiment, the unevenness is imparted by performing the third step S3, and the color arrangement is different by performing the fourth step S4. Since the 1 ink layer 13a and the 2nd ink layer 13b provided on the convex part 12 are formed, the pattern which synchronizes with a concavo-convex feeling can be provided by 3rd step S3 and 4th step S4. Thereby, it becomes possible to give the designability equivalent to actual objects, such as a natural stone, natural wood, and a tile.

Then, in the fifth step S5, a transparent UV curable ink is printed on the upper surface of the second ink layer 13b provided on the convex portion 12 by using an ink jet printer and cured.
Thereby, the transparent cover layer 15 is formed and an uneven decorative board is obtained. By performing the fifth step S <b> 5, it is possible to give a further uneven feeling and a texture close to an actual object to the obtained uneven decorative board.

In the manufacturing method of the uneven decorative board of the present invention, since the first step S1, the second step S2, the third step S3, the fourth step S4, and the fifth step S5 are included, the concave portion 11 and the convex portion 12 are included. Can be visually recognized in three dimensions, and a concave-convex decorative board can be manufactured in which a tentacle can recognize a three-dimensional effect.
Further, when natural stone is used as the object, the concave portion 11 and the pattern can be synchronized, and when natural wood is used as the object, a fine conduit hole can be expressed by the difference in gloss. When using tiles, the edges and corners are rounded, the lines between the tiles are straight lines with entry and exit, and the contrast between the glossiness and matte of the tile surface can be expressed. .

  As mentioned above, although preferred embodiment of this invention was described, this invention is not limited to embodiment mentioned above.

  For example, the uneven decorative board 1 according to the present embodiment includes a plate-like base portion 10, concave portions 11 and convex portions 12 provided on the base portion 10, and a transparent cover layer 15 provided on the upper surface of the convex portion 12.
