Abstract:
A method and apparatus for converting an input color space into a CMYK color space are provided. The method includes converting a color signal of a predetermined input color space into an sRGB color space, converting the color signal of the sRGB color space into an sRGB L*a*b* color space, and converting the color signal of the sRGB L*a*b* color space into a color signal of a printer-output CMYK color space (CMYKPrinter) using a lookup table.
