ABSTRACT:
In a method of substantially correcting gradation values in a gradation correcting unit, the number of reproducible gradations is substantially reduced. Selection information of a boundary value table for multi-value error diffusion is stored, by ejection condition, in an information storing unit of a liquid ejecting head that can represent one pixel with a large number of liquid droplets. When the liquid ejecting head is mounted, selection information matching an ejection condition is read out and a boundary value table corresponding to the selection information is set for reference by a half toning unit. Consequently, the boundary value table is optimized to correct a gradation characteristic without substantially reducing the number of reproducible gradations.
