More Information
Summary:Provided is a printing apparatus which includes an array of nozzles formed of nozzles to eject ink of a first to a fourth ink color groups, and to which scans a print medium while moving the array of nozzles to perform printing. To print a unit area of a print medium, where printing is to be completed by performing a plurality of scans, the printing apparatus performs a plurality of scans and conveys, between the movements, a print medium of a predetermined amount equivalent to the width of the unit area. Then, to perform a plurality of scans using the arrays of nozzle for the first to the fourth ink color groups, print data are generated such that for the arrays of nozzle which belongs to two ink color groups, the nozzle array for the first ink color group is employed to eject ink into the unit area prior to the arrays of nozzle for the second ink color group.
