In this example, a white pigment is used as a white colorant, and a dye ink or pigment of each color is used as a yellow, magenta, cyan, and black colorant.

FIG. 2 is a perspective view showing the head 3 of FIG. In the figure, reference numerals 3a to 3e denote ink jet nozzles for ejecting white, yellow, magenta, cyan and black colorants, respectively. A plurality of ink jet nozzles 3a to 3e for each color are arranged in a straight line parallel to each other. I have. 5a-5e are each tank 4a-4
e is a supply pipe for sending a coloring material from each of the inkjet nozzles 3a to 3e.

Next, a method of manufacturing a metal decorative board will be described. First, as shown in FIG. 3, a gold or silver rust preventive paint 6 is applied to the entire surface (decorative surface) of a metal substrate 1 made of a steel plate or the like, that is, a metallic paint is applied. Next, FIG.
As shown in (1), a white pigment and a coloring material of each color of yellow, magenta, cyan, and black are printed by a printer only on necessary portions of the surface of the metal substrate 1, that is, only on a portion to be designed.

At this time, the application position and the application amount of each coloring material are controlled by a computer (not shown) connected to the driving means 2 and the head 3. The order in which the colorant is applied to one point on the metal substrate 1 is white, yellow, magenta, cyan, and black. As described above, it is preferable to apply the coloring material in the order of the color having the highest lightness in order to more accurately reproduce the color of the original image.

Thereafter, a transparent paint (clear) is applied to the entire surface of the metal substrate 1 to form a protective film layer. Finally, the metal substrate 1 to which the transparent paint is applied is polished so that the surface becomes flat.

According to such a method for manufacturing a decorative metal plate, a white pigment is printed only on a portion of the surface of the metallic substrate 1 on which the metallic coating is applied, on which a design is applied, and the design is printed thereon. Therefore, the background color of the design is always white, thereby preventing the saturation of the color of the design from being lowered, and a clear color design can be easily formed on the metal substrate 1. In addition, since the brightness can be adjusted steplessly by coloring on white, the color expression can be 16.7 million colors or more. In addition, since the white pigment is not printed on the part without the pattern, the base color of the metallic coating can be utilized, and a beautiful metal decorative board combining the base color and the pattern of the clear color can be finished.

Further, by using a metallic paint for the base color, it is possible to give a unique feeling with a high supply feeling. Furthermore, since a white pigment that does not transmit light is used as the white colorant, the influence of the undercolor can be more reliably eliminated, and a decrease in the color saturation of the design can be more reliably prevented.

Further, the common head 3 is provided with the ink jet nozzle 3a for white pigment and the ink jet nozzles 3b to 3e for colorants of other colors, and the head 3 is driven by the same driving means 2. The white pigment can be accurately applied only to the portion where the pattern is formed. Furthermore, printing of a white pigment and printing of a pattern can be performed by one scan, and productivity can be improved.

In the above example, a metallic coating such as gold or silver is applied as a rust-preventive coating serving as a base.
Other colors such as blue and yellow may be used as the base color.

The metal substrate 1 is made of stainless steel,
When using a mirror-finished aluminum plate or an aluminum plate with a gold-anodized surface on its surface, a white pigment may be printed directly without applying rust-proof coating. Can be used as a base color, and can have a unique texture.

Further, in the above example, the application of the white pigment and the application of the colorant of another color are performed in one scan, but if the position of the head can be controlled accurately, the first scan can be performed. A white pigment may be applied to a necessary portion, and a colorant of another color may be applied in the second scan. Furthermore, in the above example, the white pigment was printed only once, but it may be printed two or more times and then coated with another coloring material, whereby the underlying color can be more reliably hidden, It is possible to more reliably prevent the saturation of the color of the design from decreasing.

Embodiment 2 FIG. Next, FIG. 5 is a perspective view showing a head of a printer for a metal decorative board according to Embodiment 2 of the present invention. In the head 3A of this example, yellow, magenta, cyan, and black inkjet nozzles 3b
3e are provided one row at a time, whereas two rows of inkjet nozzles 3a for white pigment are provided.

Thus, more white pigment can be applied at a time than the head 3 in FIG. That is, the white pigment can be applied with the same density as that obtained by double-coating with one scan, so that the underlying color can be more reliably hidden and the decrease in the color saturation of the pattern can be more reliably achieved. Can be prevented.
