In Japan, electronics industries, such as semiconductors, are experiencing strong growth. The ultra-fine processing technology called photolithography has supported this growth. Photolithography has adopted the same concept used by the phototype process in the printing field. This photolithography makes each product of the shadow mask for color televisions and the color filter for liquid crystal displays. Both of these products should be understood in relation to the historical technological background that led to their commercial production. This paper describes technological advances in the sheet-fed offset press and the history of printing-plates and proofing systems.
