Abstract

The present invention addresses the problem of improving the quality of recorded images in ink jet recording technologies in which a plurality of nozzle lines that discharge ink of the same color are used. As a solution, nozzle lines (10) of n columns (where n is a natural number of three or more) each record a recording pixel column (2) on a recording medium by discharging ink of the same color while scanning over the recording medium (1); and when the nozzle lines (10) of n columns each extract a recording pixel column (2), which is recorded in a single scan, for each n columns in the scanning direction, ink is discharged in such a manner that there are at least two permutation patterns for the nozzle columns (10) that record each column of the extracted recording pixel columns (3).

Dependent claims

An inkjet recording method, comprising:

a scanning process in which nozzle arrays of “n” rows for ejecting ink of same color are scanned on a recording medium along a scanning direction and the nozzle arrays respectively eject ink on the recording medium to respectively record recording pixel rows on the recording medium, wherein “n” is a natural number of 3 or more;
wherein each of the nozzle arrays is comprised of one nozzle or more nozzles aligned along a sub-scanning direction perpendicular to the scanning direction, and the nozzles of the respective nozzle arrays are aligned along the scanning direction;
and
wherein, in the scanning process, the respective nozzle arrays of the “n” rows eject ink so that, when the recording pixel rows recorded by one scanning are extracted every “n” rows along the scanning direction, number of permutation patterns of the nozzle arrays for recording respective rows of extracted recording pixel rows is two or more.
