Through the provision of the pattern through a variety of coloring and / or pattern formation is possible relates to a color steel plate combines functionality and design.

기존에 건재나 가전제품에 사용되어 온 소재에 시각적, 미적 변화를 주기 위하여 강판 표면에 여러 가지 패턴과 칼라를 적용하여 수요가의 다양한 요구에 대응하기 위한 시도가 계속되고 있다.In order to give a visual and aesthetic change to materials that have been used in building materials and home appliances, various attempts have been made to apply various patterns and colors to the surface of steel sheets to meet various demands of demand.

이러한 다양한 시도 중의 하나로서 스테인레스 강판 표면에 헤어라인 무늬를 형성한 예가 있는데, 소재강판인 스테인레스가 고가여서 제조원가가 높고, 헤어라인 무늬 형성 후에 지문 자국이나 외부오염으로 인하여 강판 표면이 쉽게 더러워지는 경향이 있었으며, 이를 해결하기 위한 방안으로 추가적인 도장처리를 시도하기도 하였으나, 스테인레스 소재의 특성상 도료, 잉크 등과의 소재 부착성이 어렵기 때문에 도장을 이용한 기술적, 미적 표현에 한계가 있어서 수요가의 요구에 적절하 게 부응하지 못하는 문제가 있었다.One example of such various attempts is to form a hairline pattern on the surface of a stainless steel sheet, which is expensive because stainless steel, a material steel sheet, is expensive, and the surface of the steel sheet is easily stained due to fingerprint marks or external contamination after the hairline pattern is formed. In order to solve this problem, an additional coating treatment was attempted. However, due to the nature of stainless steel, it is difficult to adhere materials to paints and inks, so there is a limit in technical and aesthetic expression using coatings, which is suitable for demand demand. There was a problem that did not respond.

이에 저가이면서 스테인레스에서와 유사한 헤어라인 무늬를 재현하기 위하여 헤어라인 무늬가 인쇄된 라미네이트형 필름을 강판에 접착시켜 표현하는 방법이 사용되기도 하였지만, 이 경우 인쇄된 상태의 무늬의 한계 때문에 사실적이고 입체적인 느낌이나 질감 구현 및 안정성에 문제가 있었다.In order to reproduce the hairline pattern similar to that of stainless steel at low cost, a method of adhering the laminated film with the hairline pattern printed on the steel sheet was used. However, in this case, the realistic and three-dimensional impression is due to the limitation of the printed pattern. There was a problem with texture implementation and stability.
