오프셋 인쇄에서 실리콘 잉크의 평판인쇄 적성에 관한 연구

Abstract

In this study, lithographic printability of silicon ink in offset printing was studied. As printed electronics uses silicon ink in contact formation, this technique requires to reproduce the high quality of patterning with high demand. Lithographic offset printing could print faster than screen printing but the amount of ink transfer rate is lower because the offset lithography is used the Roll to Roll (R2R) system. Six types of silicon inks with different viscosity (10, 50, 100, 200, 300, 500Poise) and optical density were used in this study and we found that optical density, ink transferred rate and glossiness of samples were measured by IGT printability tester. As the result, the Rheological properties were well fit on these conditions and were able to print by lithography.
