Abstract:
1. A print-control method comprising: a first print-control step of repeatedly performing a unit image formation operation of forming a unit image in a unit area on a medium by ejecting ink from a plurality of nozzles that are arranged in a predetermined direction and that are moved in a movement direction, and a first carrying operation of carrying said medium by a predetermined carry amount, so as to print an image in an end portion, in a carrying direction in which said medium is carried, of said medium; and a second print-control step of repeatedly performing said unit image formation operation and a second carrying operation of carrying said medium by an other predetermined carry amount, so as to print an image in an intermediate portion, in said carrying direction, of said medium; wherein darkness of each of the unit images within said end portion, in which unit images that are printed in said first print-control step, is corrected based on an end processing correction value, wherein darkness of each of the unit images within said intermediate portion, in which unit images that are printed in said second print-control step, is corrected based on a normal processing correction value, and wherein darkness of each of the unit images within a mixed range, in which unit images that are printed in said first print-control step and unit images that are printed in said second print-control step are mixed in said carrying direction, is corrected using an amended correction value obtained by amending the normal processing correction value that is used in said second print-control step.
