Patent number: 10906350Abstract: The present application relates to a pattern forming method for quartz surface and a pattern forming device for quartz surface. According to the pattern forming method for quartz surface of the present application, by comprising a step of forming a pattern and a step of forming a color, it is possible to freely express the color on the pattern simultaneously along with forming the pattern on the quartz surface. And, in addition to these steps, by optionally comprising a step of additionally forming a pattern, it is possible to freely form a desired pattern on the quartz surface, and, by adding long line type patterns on the quartz surface unlike existing conventional quartz surfaces, it is possible to produce the quartz surface showing patterns and textures which are more natural and close to natural stone.Type: GrantFiled: November 15, 2017Date of Patent: February 2, 2021Assignee: LG Hausys, Ltd.Inventors: Jin Seok Kwak, Suk Whan Ko, Joong Heon Lee, Ju Yeon Won, Jung Sang Lee, Paul Lee, Yang Won Yun, Chung Man Kim
