마스터 공구는 그의 주 표면 상에 잉크 패턴이 마련된다. 잉크 패턴은 스크린 인쇄 공정에 의해 형성된다. 스탬프-제조 재료를 마스터 공구의 주 표면에 적용하여, 마스터 공구의 잉크 패턴에 대해 네거티브인 스탬핑 패턴을 갖는 스탬프를 형성한다. 스탬핑 패턴에 잉크 조성물을 잉크칠하고 금속화된 표면과 접촉시켜, 스탬핑 패턴에 따라 기재의 금속화된 표면 상에 인쇄 패턴을 형성한다. 인쇄 패턴을 에칭 마스크로서 사용하여, 금속화된 표면을 에칭하여, 기재 상에 전기 전도성 트레이스들을 형성한다. A master tool is provided with an ink pattern on a major surface thereof. The ink pattern is formed by a screen printing process. A stamp-making material is applied to the major surface of the master tool to form a stamp having a stamping pattern being negative to the ink pattern of the master tool. The stamping pattern is inked with an ink composition and contacted with a metalized surface to form a printed pattern on a metalized surface of a substrate according to the stamping pattern. Using the printed pattern as an etching mask, the metalized surface is etched to form electrically conductive traces on the substrate.
