Abstract
그라비아 프린팅 공정에서 고해상도의 패턴을 인쇄하기 위해서는 잉크가 기판으로 전사되는 양을 높이는 것이 중요하다. 일반적으로 잉크와 기판의 친화도가 높을수록 더 많은 양의 잉크를 전사시킬 수 있다. 하지만, 실제 산업에서 쓰이는 점탄성 잉크와 다양한 기판의 친화도를 정확히 평가하는 방법은 아직 제시된 바 없다. 본 연구에서는 점탄성 잉크와 다양한 기판의 계면 친화도를 실용적으로 평가할 수 있는 방안을 제시하고자 한다.
To produce patterns with high resolution in gravure printing, it is important to increase ink transfer ratio. The ink which has higher affinity with substrate can be transferred more from the roll to the substrate due to the good wettability between ink and substrate. However, it is difficult to evaluate the affinity between the substrate and the ink which is viscoelastic in nature. In this study, we suggest a practical method to evaluate the interfacial interaction between the ink and various substrates.
