스크린 인쇄에서 인쇄속도와 잉크점도에 따른 잉크전이 시뮬레이션에 관한 연구

Abstract

Recently, Screen printing are changed into automation and it can be possible to make accurate printing. However, there have been lots of trial and error to get perfect result. Also, much time and money must be input in this process. So, before printing progresses, if screen printing process becomes visualization by simulator program. finding optimum point will be in a short time and it was judged that printing result will be collected more exactly and efficiently. In this study, figure out optimum printing speed and ink viscosity by FLOW-3D program and get the result almost accorded with experiment. Through this study, it would be expected that the application of the screen printing method will be extended with screen printing advantage by using simulator program.
