Abstract: 본 발명은 알루미늄판상의 옵셋 인쇄 방법에 관한 것으로서, 더욱 상세하게는 알루미늄 원판 4도 옵셋 인쇄에 별도의 색을 입히고, 그 판을 전방으로 돌출시켜서 입체감을 주도록 한 알루미늄 재질을 이용한 옵셋 인쇄 방법에 관한 것이다.  본 발명의 방법은, 알루미늄 재질상의 옵셋 인쇄 방법에 있어서, 알루미늄 원판상에 옵셋 인쇄를 하기 위해서 시안, 마젠타, 황색 및 흑색의 4장의 필름과, 별도의 색을 위한 필름을 제작하는 단계와(단계 1), 상기 4장의 필름 각각에서 별색 인쇄를 위한 부분을 긁어내어 공란으로 만드는 단계와(단계 2), 상기 4장의 필름을 이용하여 알루미늄원판상에 4도 옵셋 인쇄를 수행하는 단계와(단계 3), 상기 별도의 색을 위한 필름을 이용하여 단계3에서 공란으로 남은 부분에 별색을 인쇄하는 단계와(단계 4), 상기 인쇄가 완성된 알루미늄원판상의 인쇄된 면을 보호하기 위한 보호 테이프를 부착시키는 단계와(단계 5), 입체 금형을 제작하여, 인쇄된 알루미늄원판의 특정 부분을 인쇄된 면의 배면에서 가압하여 인쇄된 면중 가압된 부분이 인쇄된 면의 전방으로 돌출되게 하는 단계와(단계 6), 인쇄된 알루미늄원판의 배면에 양면 테이프를 부착하는 단계와(단계 7), 인쇄 및 돌출된 알루미늄 원판을 절단하여 싱귤레이션하는 단계와(단계 8), 단계 5에서 부착된 보호 테이프를 벗기고 인쇄된 면에 코팅을 입히고 열처리하는 단계(단계 9)를 포함하여 이루어진다.
