Abstract:
A method of setting ink discharge density for coloring one line of a colored portion of a color filter, said one line being colored by a plurality of inks discharged from a plurality of ink discharge nozzles with a common ink discharge density, said method comprising the steps of:forming the colored portion extended along a scanning direction by relatively scanning the plurality of ink discharge nozzles and a substrate, and discharging inks on the substrate with a common first ink discharge density from each of the plurality of ink discharge nozzles, said one line of the colored portion being formed by the plurality of ink discharge nozzles;detecting a color density Dn of the colored portion after said forming step; andsetting a common second ink discharge density by changing the common first ink discharge density into the common second ink discharge density, which is the same on each of the plurality of ink discharge nozzles, on the basis of the color density Dn detected in said detecting step so that a color density of the colored portion becomes a target color density D.
