The present invention relates to a method of directly painting a pattern on a veneer board, and more particularly, to a method of coloring a desired natural wood pattern as desired on the surface of a veneer board having an arbitrary uneven surface.

Conventional veneers are selected from expensive teak, rose wood, sakura, walnut and jeburano trees. Among them, decorative plywood has been manufactured through several stages of work by pressing several pieces of veneer formed by cutting only the patterned part with width less than 200m / m with adhesive to plywood in parallel and pressing and drying with press machine etc. There was also a flaw that the nature of the pattern itself could not be saved.

In other words, there is a problem that it is impossible to follow the elegant and beautiful shapes of the primary colors according to the various patterns and delicate concentrations that the natural patterns actually support, such that the imitation of artificial patterns is completely identified because the width and density of the limited veneer are not properly reproduced. there was. On the other hand, JP-A-60-248,306 discloses a `` manufacturing method of artificial decorative veneer '' as another conventional technique, but this technique forms a speckle by applying a dye to a single plate obtained by cutting wood. In order to laminate a plurality of patterned end plates, they were pressed by a press, and the laminated end plates were cut thinly to obtain a wood grain makeup plate. There is a disadvantage, in particular that the user can not give any natural pattern color as desired.

As a result of earnestly researching to solve the above problems, the present invention forms a specimen plate that is a natural pattern of solid wood, or a specimen plate that artificially depicts a natural pattern, and the patterns of these specimen plates are color bands (wood grain). Prepare several screen printing plates, which are transferred to the plate, and place the printing plates on a veneer plate having an uneven surface of arbitrary shape, and then print them, and then put them in an airtight container and heat them to change the natural pattern of primary colors. It was found to be naturally colored on the veneers.

That is, the present invention was invented by this fact. On the surface of the veneered plate having an arbitrary pattern-shaped uneven surface, the screen printing plate formed with the natural pattern of wood in the color band (wood grain) was placed in the order of the color band and screen printing was performed. The natural pattern of primary color is printed on the uneven surface, and the natural pattern color is colored on the uneven surface by varying the concentration by putting the Bayer plate printed with the pattern in an airtight container and heating with steam heat of 85 to 95 ° C. . The features and advantages of the present invention will become more apparent on the basis of the embodiments according to the accompanying drawings.

The present invention is in no way limited by the following examples.

<The first process>

Sample board (4) imitating the natural pattern (3) of the form to be obtained by arranging in parallel the veneer (2) obtained by cutting the normal wood (1), or the specimen board which artificially embodied the natural pattern ( 4 ') to form a pattern (3) or (3') of these specimen plates (4) or (4 ') with color bands (5) (5') (5 ") (5 '") (5 "" (6 ') (6') (6 '") (6").

And the natural pattern (3) or (3 ') of the specimen plate (4) or (4') on the surface of the roller (7) as one of the work for embossing (uneven) on the surface of the veneer plate (A) that is the adherend When the surface of the veneer plate A is stamped with the roller 7 by stamping a pattern of any shape or any shape, the uneven surface 8, 8 ′ is formed on one surface of the veneer plate A.

<The second process>

In the process, the vegetable primary color 9 which matches the property of the veneer board is combined with the dyeing or printing method on the surface of the veneer board A which comprises the uneven surface 8 (8 '). If you use the original veneer color as it is, you do not have to dye it. Next, a screen printing plate 6 '(6 ″) (6' ″) (6 ″ ″) is placed on the uneven surface 8 (8 ') of the veneer plate A (5) (5') (5 ″). (5 '″) (5 ″ ″), the wood grain pattern is printed on the uneven surface 8, 8'. The printing method is to remove the screen printing plate 6 immediately after printing the color strip 5 on the screen printing plate 6 on the uneven surface 8, 8 ', and then place the next screen printing plate 6'. Printing is performed, and then the printing operation is continued in the same manner to obtain a pattern in a state as shown in FIG. 2A. In this embodiment, the printing of 4 degrees is exemplified, but it may be less or more depending on the number of wood grains.

Color stripe printing of wood can be sorted and printed according to the user's taste. Since the operation of moving the sample pattern to the screen printing plate and the printing method in the above is a general technique, a detailed description thereof will be omitted. The printed veneer plate (A) is placed in a sealed container (100) and heated by steam heat of 85 to 95 degrees Celsius, and the color strips (5) (5) printed on the uneven surface (8) (8 ') of the veneer plate (A). Printing ink of ') (5 ″) (5' ″) (5 ″ ″) penetrates 1 ~ 2mm inside from the surface of the uneven surface 8 (8 ') to be colored and looks like a natural pattern To effect.

In particular, in the surface portion of the veneer plate A, in which the shape of the natural pattern 30 (3 '), such as that of the pyramids 4, 4', forms an uneven surface 8, 8 ', is lightly applied to the recessed portion 8. On the contrary, on the convex portion 8 ', the color strips 5, 5 by screen printing plates 6, 6', 6 &quot;, 6 '&quot;, &quot; 6 &quot; By expressing more color effect than the color of ') (5 ″) (5' ″) (5 ″ ″), it is possible to freely manufacture and supply elegant and beautiful natural patterns to the demands of the real user by supplying them at low price. Has an economic effect.

Claims (1)

In the conventional method of coloring the pattern on the surface of plywood or veneer, the natural pattern of wood is applied to the surface of the veneered plate on which arbitrary patterned irregularities 8 and 8 'are formed. Put the screen printing plates 6, 6 ', 6', 6 ', and 6' in the order of the color bands. Screen printing is carried out, and the entire surface of the uneven surface is printed with a natural frequency of a primary color, and a pattern printing dye solution is prepared by heating the veneer plate on which the pattern is printed in a sealed container 10 and heating it with steam heat of 85 to 95 ° C. A method of directly painting a pattern on a veneer board, characterized by coloring on uneven surface with different concentrations.
