摘要： Provided is a surface-treated metallic material with easy control of glossiness and a manufacturing method therefor, the surface-treated metallic material comprising: a metallic material; and a coating layer which is formed on at least one side of the metallic material and on which an ultraviolet curable coating composition is cured, wherein the coating layer consists of a plurality of protrusions, which have a volume of 3 to 16 pico liters and are arranged at a density of 5 to 610 per 1 mm2 of the metallic material. As such, the surface-treated steel sheet is excellent in adhesion, scratch resistance and corrosion resistance, and has easy control of glossiness.

摘要： A method of manufacturing a transparent pattern printed steel plate includes forming a printed paint film layer by jetting transparent ink onto at least one surface of a steel plate, and curing the printed paint film layer with ultraviolet light to form a cured printed paint film layer. Further, a method of manufacturing a transparent pattern printed steel plate includes preparing a steel plate having a color painted film layer formed on at least one surface thereof, forming a printed paint film layer by jetting transparent ink onto the color painted film layer, and curing the printed paint film layer to form a cured printed paint film layer.
