A specific gamut of colors extending a reproduction range of colors in a color space is set to make for any ink color belonging to the specific gamut a conversion from CMYK dot pattern data into numbers of ink drops to be discharged from an inkjet head, using as a lookup table an extended pattern table having a maximal drop number 7. For ink colors belonging to a gamut of colors outside the specific gamut, a default pattern table having a maximal drop number 5 is used as a lookup table for the conversion from CMYK dot pattern data into ink drop numbers. |
