Abstract:
A method of manufacturing a color filter by scanning an ink-jet head relative to a color filter substrate and discharging ink from the ink-jet head onto the color filter substrate to color the color filter substrate, comprising:a measuring step comprised of determining at least two different ink discharge densities, coloring a coloring-target medium, using the at least two different ink discharge densities, and measuring color densities of colored portions of the coloring-target medium;an operation step of obtaining a relationship between color density and ink discharge density based on the respective color densities of the colored portions colored by the at least two different ink discharge densities and corresponding ink discharge densities; anda coloring step comprised of determining an ink discharge density which attains a desired color density based on the obtained relationship between color density and ink discharge density, and discharging ink onto the color filter substrate at the determined ink discharge density, thereby coloring the color filter substrate.
