The table 200 represents that only small dots should be formed in the range Cd1 of relatively small tone values. In the range Cd2, the production rate of small dots gradually decreases, while the production rate of medium dots increases. In the range Cd3, the production rate of small dots and medium decreases, while the production rate of large dots increases. Consequently, small dots, medium dots, and large dots are intermingled, with the proportion of large dots increasing in association with higher tone values. According to the present invention, printing is able to be implemented while switching among dot apportionment tables depending on the object represented in one set of image data, and printing using small dots is able to be implemented efficiently in areas where low grainy appearance is required, namely areas corresponding to human faces.
