A METHOD AND EXPERIMENTS OF DETERMINING THE OPTIMUM PARAMETERS OF COATED ART PAPER PRINTING
By experimental method, the optimum parameters of coated art paper printing were achieved, and the results of tonal and color reproduction based on these parameters were tested and analyzed. Results showed that the optimum printing contracts of KCMY colors were 0.38, 0.43, 0.39 and 0.32 respectively, and the matched optimum solid densities were K_1.8～1.9, C_1.6～1.7, M_1.5～1.6 and Y_1.3～1.4. The TVI curves of the prints based on these optimum parameters were relatively smooth with a reasonable range of dot gains, the location of the process colors and overprint colors in the CIE LAB space were satisfied, the ink trappings of RGB overprint colors were 63.1％, 71.8％ and 62.9％ respectively, showing a good ink transference, and the maximum total dot area coverage was 352％. Results showed that the method of determining the optimum parameters of coated art paper printing derived from this paper was effective and reliable, and it can be used to research the printability of papers and inks, optimize printing process, improve printing quality and provide method to standardize management for printing companies.
