Abstract
Roll-like ink sheet is divided in a virtual manner into a plural number q of groups in the sub-scanning direction of ink sheet. In each of the groups, a plural number p of printing areas displaced in the sub-scanning direction are formed in a virtual manner. Print areas are partitioned in a virtual manner into a plurality of blocks in both main scanning direction and sub-scanning direction. Second accumulated printing ratio &eegr;2 for each of the blocks according to an image to be printed is calculated using first accumulated printing ratio &eegr;1 for each of the blocks. In a plurality of printing areas consisting of only blocks having second accumulated printing ratio &eegr;2 equal to or less than predetermined value &eegr;0, evaluation value for each of the print areas, dependent upon second accumulated printing ratio &eegr;2, is calculated. Any print area having a small consumption amount of ink is used for printing according to the evaluation value.
