PROBLEM TO BE SOLVED: To realize 'shortening of time for preparation before printing', 'alleviation of labor load', 'saving of printing materials', 'improvement of production efficiency', 'reduction of cost', etc. SOLUTION: In this method, the amount of necessary production (number of printing sheets) N1 determined on the basis of a production plan and the number N2 of printing sheets necessary for correction of a film thickness of ink are set in a preset counters 11-1 and 11-2 and a select switch is set in 'interlocking'. When a count value of the number of printing sheets reaches N1, automatic correction of the film thickness of ink is started. In this automatic correction, printing in the number N2 of printing sheets is executed in a state wherein an ink call operation is stopped. Thereby an ink film thickness distribution Mb corresponding to a pattern of an impression plate set at present is removed from an ink roller group and an ink film thickness distribution (a minimum ink film thickness distribution needed in printing) Ma is left. |
