Generally, signboards are used to advertise to consumers the goods that are installed on the building, such as mutual goods and the like, and the signboards for such purposes can be easily recognized by the consumer and can be recognized and appreciated compared to other signboards .

In recent years, a surface-emitting LED signboard using a three-dimensional member formed by shaping a character or a figure into a three-dimensional shape has been widely used in order to increase the discrimination of the signboard. In such a surface-emitting LED signboard using such a three- It is fabricated in such a way that it is bonded on the base plate.

Such a surface-emitting LED signboard facilitates identification in a three-dimensional shape during the daytime and enhances the discrimination power of each character by using a light-emitting means such as an LED provided in the nighttime.

There are various types of surface emitting LED signboards such as front emission, back emission, side emission, triple emission, dot emission, front emission and back emission.

In recent years, in order to obtain the maximum advertising effect by enhancing the discrimination power of the signboard, there is a tendency to use a lot of things made by wearing various colors on three-dimensional members such as letters, marks, and logos.

In the case of a signboard using a solid member of various colors, in order to maximize the light efficiency of LED illumination irradiated inside the solid member, the inner surface of the solid member is usually treated as white.

For example, the entire surface of a sheet material such as acrylic, which is the material of the three-dimensional member, is coated (for example, by powder coating) in a color such as red, yellow, green, blue or orange, , A three-dimensional member having a color that has been painted on its surface and a white color on its back surface is manufactured and used.

However, in the conventional method of manufacturing a three-dimensional member having various colors, since the operation of applying white to the back surface of the plate depends on the manual operation of the operator, the operation is very troublesome, the operation time is long, It is difficult to secure the quality and it is difficult to secure the quality. When white is applied to the surface of the plate when white is coated on the back surface of the plate, the worker must use a brush or the like to cover the surface of the plate with the color of the surface Overall, there is a drawback that the efficiency of the work is poor.
