PROBLEM TO BE SOLVED: To create correction data with which quality of image printed by an inkjet printer is certainly improved.SOLUTION: A plurality of examination patterns are printed, in which different concentrations are designed (S101). Then, a reading device reads the plurality of examination patterns to obtain a plurality of image data of the examination patterns (S102). Then, concentration information of corresponding parts to each of nozzles for the examination patterns is obtained from the image data (S103). Then, from the designed concentration designed to the plurality of examination patterns in S101 and the concentration information obtained in S103, concentration modification ratio as a ratio of modification degree of the concentration in examination patterns to be printed relatively to modification degree of the designed concentration upon printing the examination patterns with changed designed concentrations is calculated for the plurality of nozzles to create correction data based on the concentration modification ratio for the plurality of nozzles. |
