PROBLEM TO BE SOLVED: To easily select and establish HS data for correcting a density unevenness in a printed result. SOLUTION: A predetermined density pattern 706 is printed based on predetermined print data corrected for a density by using a head shading (HS) data 702, and a code 704 indicating the data 702 used for its upper part is printed. Thus, an effect of HS is judged by the pattern 706. When the data 702 is used for following printing, the HS data can be selected or established by the code 702. |
