PROBLEM TO BE SOLVED: To accelerate the shortening of preparation time before printing, the reduction of labor load, the saving of printing materials, the improvement of production efficiency, the reduction of manufacturing cost and the like. SOLUTION: The density of respective colors of a simple printed matter forming the samples of printed matter to be printed next is measured (S106). The measured density values of respective colors are collated with the preliminarily specified reference density values of respective colors (S108). In the case the reference density values of respective colors are different from the measured density values of respective colors, the ink calling numbers of respective colors specified in compliance with fluctuated values formed between the reference density values and the measured density values are used as the ink calling numbers at the time of preinking 2 operation. |
