ABSTRACT:
The invention relates to a method for setting a tolerance of each standard value, which is a factor in determination of ink droplets landing accuracy, to an ink jet printer that is set up using the method, by implementing a sensory test using printed results of an ink jet printer. With the tolerances set by the method, banding can be effectively obscured without significantly improving the mechanical precision of the ink jet printer. Particularly, when A1is a deviation of a sheet feeding amount in the sub-scanning direction obtained by a dot line length of an average value of the sheet feeding amount in the sub-scanning direction from an ideal value, B1is a maximum value of a deviation in the sub-scanning direction between the same color dots, and C1is a maximum value of a deviation in the main scanning direction between the same color dots, it is set such that a value of tolerances of A1, B1, and C1is A1≦B1≦C1.
