Recently, the development of various media images has led to the height of the reader's eye level, which is higher than the eye level of readers of printed matter. It is a situation that is doubling. Moreover, in the textbooks for students, design elements and photograph elements for visual educational effect obtained from the previous reading-oriented editing are inserted, and the color quality is more important than ever. Therefore, in recent years, textbooks also require the application of a color management system, which is applied to general commercial printing, and there is an urgent need to standardize the production of the printing plate as a starting point. In addition to the development of computer, the production process of the printing plate is changing rapidly with the new manufacturing method of CTP(Computer To Plate), and the CTP takes up most of the production cost of the whole printing plate. However, according to the CTP light source and the photosensitive material, various kinds of methods are used. In the case of the thermal method, which is mainly used in the main printer, the exposure time and development conditions are different according to the manufacturer or product type, The results tend to be significantly different. Therefore, in this study, we tried to find proper exposure range of CTP equipment and proper development speed and temperature of developing process through field experiment. In addition, we tried to confirm the stability of the CTP plate which is being used at present by carrying out the chemical resistance test on the chemicals used in the printing process. The results obtained from this study are aimed at building standard data for stable supply of standardized quality materials to high quality book printing, further stabilization of the quality and standard setting of the printing plate through securing basic data. I want to.
