Even though we could not count the total amount of plates in Korean printing industry per year, we would suppose the total amount of plates about $20,000km^2$ to $22,000km^2$ per year through our printing experience. On the standard of the end of 2010, it would be the market share of plates are that CTP plate is $9,000km^2$, CTcP plate is$4,000km^2$ and PS plate is $9,000km^2$, such as total amount of plates are $22,000km^2$. When there was no installed CTP setter in Korea, the domestic plate would be over 60% market share of plate in Korean printing industry. But now it would be less than 25% market share of plate. It is necessary to develop domestic CTP thermal plate from now because we have to keep the market share of domestic plate. On the study of the surface structure of substrate, roughness, anodized layer amount and coating amount between domestic CTP thermal plate and foreign CTP thermal plate, it would be the basic to develop domestic CTP thermal plate.

Computer to plate technology(CTP) have become fully commercial. The current wide range of computer to plate system and plate makes many potential customers insecure. This process which began around 1995 has now been successfully completed, so that a wide variety of high performance systems is available. The computer to plate method of producing printing plates eliminates films from the production process, thus reducing costs and shortening production times. To discover the optimization formulation of sensitized materials we were changed formulation of resin and violet solution in thermal sensitizers. Also we were analyzed the CTP plate's surface and the result of coating and development at each sample. we were analyzed the effects of development condition as temperature and speed, the plate wear of printing test in C, M, Y, Bk ink. This paper aims to find out suitable ways that we can develop a domestic CTP plate.
