Abstract

A color-filter manufacturing method which can greatly reduce density unevenness among pixels of a color filter. To make the amount of ink discharged for each pixel constant, a theoretical ink discharge pitch D is calculated for each of ink-discharge nozzles in accordance with an amount of ink discharged per single discharge of each of the plurality of ink-discharge nozzles, and ink is discharged such that, assuming a minimum moving pitch of an amount of relative movement of the ink-jet head in the scanning direction is d, in a case where a value kD (k is an integer equal to or larger than 0) corresponding to a theoretical discharge position of an n-th ink dot discharged along the scanning direction coincides with nd (n is an integer equal to or larger than 0), ink is discharged at a position satisfying kD=nd, and in a case where kD takes a value between nd and (n+1)d, ink is discharged at a position corresponding to nd or a position corresponding to (n+1)d.
