QUALITY RESEARCH OF PAPER COLOR MANAGEMENT SYSTEMS

Abstract

Paper color is one of the most important indicators of paper quality. Currently there is no information on functional color management systems. The study contains an analysis of information on the quality of color management on various paper machines for the production of printed papers. The research methodology consisted in the formation of a sample of numerical values of color coordinates in the CIE system from the archives of the APCS servers and laboratories of quality departments at factories. The analysis of the quality of operational control systems was carried out on the basis of the calculated histograms of the color coordinates of finished paper. The article presents the results of statistical processing of data about changes in the color coordinates L, a, b of the finished paper. Based on those results, the correlation of the dosage of chemical reagents and the color of the paper web is visible.
