Abstract
Inputted multivalued image data is first stored in an image memory, and the multivalued image data is converted to binary data for driving each of a plurality of ink-jet head units, which discharge different colors of ink or ink with different densities, by referring to an ink-type distribution table based on the multivalued image data read out of the image memory. The converted binary data is stored in an address of the image memory, where the corresponding multivalued image data has been stored. The binary data stored in the image memory, each bit of which is to be outputted to each ink-jet head unit, is read out and outputted to the corresponding ink-jet head unit.
