PROBLEM TO BE SOLVED: To upgrade the quality of a printed image in the printing process to form dots on a printing medium by executing a main scan and a subscan operation. SOLUTION: First, in the step S2, a user prints a test patch on a printing paper in respectively different dot recording modes. Each of the dot recording modes shows a difference in the feed of a printing head for the subscan to be performed between the main scans, although the main scan procedures are the same as specified, with regard to each dot recording mode. Each test patch is printed using three different color inks, that is, pale-color cyan, pale-color magenta and yellow. In the step S4, the user selects the test patch which appears to be most uniform among the other test patches. After that, the user enters a number attached to the selected test patch to the computer in the step S6. Thus it is possible to perform the high-quality printing by selecting a dot recording mode through actually printing the test patch in each of the dot recording modes. |
