Using a UV printer on the semi-dry adhesive layer is subjected to a printing step (S15) in which the pattern is UV-printed. Since the pattern is printed on the adhesive layer by an ultraviolet printer, the pattern is dried together with the adhesive to further increase the durability and clarity of the pattern. The range in which the pattern layer is formed is formed only in the adhesive layer. When printed on other parts, the pattern may be damaged by the diluent added to the paint, so that the pattern is printed only on the adhesive layer. Therefore, a pattern is printed on the adhesive layer precisely using a computer. Foreign matter such as dust may be formed on the design layer before the deposition step, but it is necessary to go through the cleaning step to remove it, but the above cleaning step may be omitted if the work is performed in a place such as a clean room. have. That is, when the operation is performed in a place where foreign matters such as dust may be removed, the cleaning step for removing dust or the like formed on the upper portion of the pattern layer may be omitted. Therefore, after the printing step, the deposition step S16 in which the aluminum deposition layer is formed on the pattern layer may be performed. The deposition step S16 is a step of forming a mirror. Vacuum deposition of aluminum forms a deposition layer. After the deposition step is to go through the paint coating step (S17) as a finishing work to protect the deposition layer. As a paint coating method, a paint coating containing a diluent solution is directly applied by using an injector or the like, and dried in a drying furnace at a temperature of 150 to 170 ° C. In addition, powder coating method can be used.
