GOLD POWDER AND SILVER POWDER PRINTING METHOD FOR THREE-DIMENSIONALLY PRINTING GOLD POWDER AND SILVER POWDER FOR CRAFTS AND CURING SAME BY ULTRAVIOLET RAYS

摘要

The present invention relates to a gold powder and silver powder printing method for three-dimensionally printing gold powder and silver powder for crafts and curing the same by ultraviolet (UV) rays, capable of applying a distinctive gloss of a gold color by giving an effect of painting and coating gold powder over the gold color when expressing a specific pattern or letter in gold on a printed matter such as an edge pattern of a certificate of merit, a business card, a wedding invitation, and the like, enabling aesthetic color expression since the amount of light reflection greatly changes in accordance with the angle due to a high refractive index of light, providing a three-dimensional effect as if it were carved by forming an embossed printed layer having strong hiding power, and requiring no separate drying time. The method comprises: (a) a step of manufacturing a gold powder and silver powder mixture by mixing gold powder and silver powder for crafts with an etching matte UV emulsion; (b) a step of mixing a curing agent with the gold powder and silver powder mixture; (c) a step of forming a thick film by applying a sensitizing solution to the surface of a screen; (d) a step of compressing a film on which a pattern is printed on the screen and exposing the same; (e) a step of removing the film and washing the screen; (f) a step of placing the screen on a raw sheet on which gold powder and silver powder are to be printed, and applying the gold powder and silver powder mixture; and (g) a step of curing the gold powder and silver powder mixture by UV rays.;COPYRIGHT KIPO 2018
