A Study on Optical Analysis and Overprinting Sequence in 2-Color Solid Overprints

2색 중첩 민인쇄의 광학적 해석과 중첩인쇄 순서에 관한 연구

Existing cleaning solvent using screen printing are the organic solvents including aromatic compounds carried with poisonous and stench. besides, Cleaning method of current screen printing are for the most part mixed cleaning method of dipping and polish. Using 1,1,1-TCE, CFC-113 alternative system cleaning solvent be substituted for existing cleaning solvent against screen printing ink measured the cleaning efficiency according to gravimetric analysis method and property change of gassamer according to Image Analyzer. Also, Cleaning process system carry with excellent cleaning efficiency studied which was proposed new cleaning process including ultrasonic cleaning process be substituted for existing mixed cleaning method of dipping and polish.
