Due to the development of digital technology, in order to copy with small quantity and mulit-product prints, a traditional printing companies are rapidly entering aggressive unit price competition. .One of the ways to actively copy with it, by utilizing the applications if the existing traditional printing equipments, which are being advanced, is intneded to strengthen unit price competitiveness, increase uniformity and accuaracy of print quality and quantify print quality. Production cost while maintaining the uniformity and accuracy of the existing print quality by utilizing a various functions as well as the function of simply passing the ink key value to the printing equipment using PPF data, one of the CIP options that we are currently using most commonly, It aims to provide opportunities for a traditional printing companies to actively seek alternatives and intensifyng unit price competition. I hope that it will help you to accurately understand the use of applications that are becoming more sophisticated, identify the advantages and disadvantages that can be obtained by using them and actively replace them. Based on an accurate understanding through the use of these applications, I hope that the introduction of digital printing equipment and the grafting of advanced technologies such as smart factories, etc., are faithfully implemented, while proactive measures are taken to quantify the print quality through objectification and standardization of print quality

Textbooks are the main teaching materials of students who use them for education. Therefore, in education, it is an essential tool for all students across the country. Accordingly, the work of producing textbooks, a tool that is the basis of education, is produced through a very systematic process. Currently, the percentage of students is decreasing by 3.0 percent every year from 2009 to 2020. However, parents and other customers are increasingly demanding higher levels of education and higher quality textbooks in this era when private education is becoming a necessity for their children. Accordingly, publishers that produce textbooks are making great efforts to improve quality by using eco-friendly materials to produce textbooks. Therefore, the results of this study were compared and analyzed after examining the current status of the causes of problems in printed materials that may occur during the course of textbook production, reflecting the changes in the environment of the times related to such textbook printed materials. As a result, ink and paper have an inseparable relationship with printing, and trouble caused by ink and paper occurs during printing work, reducing the efficiency of printing work. In addition, quality surveys were conducted on each sample of 60g/m2 and 65g/m2 of eco-friendly paper. ink transfer volume, color density degradation, dry down, show trough and overall results were satisfactory. This study carried out this quality survey. Based on this paper, we will check and secure errors that appear in textbook production in advance so that they can be used as basic data to improve the quality of textbooks. It is also believed that the quality of printed materials will be further enhanced by continuous research using the collected data.
