An image data creating device includes a converter that converts first image data defined by an input signal value to second image data defined by an output signal value of a CMYK color space, and a changer that changes, in forming a mixed color represented by mixing at least two of a cyan ink, a magenta ink, a yellow ink, and a black ink, based on the second image data, the second image data such that at least a portion of the cyan ink, the magenta ink, the yellow ink, and the black ink is replaced with a first special color ink that has a first special color that is a color other than cyan, magenta, yellow, and black. 1. An image data creating device comprising:a table memory that stores a first table that indicates a correspondence relation between an input signal value and a saturation value of a device-independent color space, a second table that indicates a correspondence relation between an output signal value of a CMYK color space and the saturation value of the device-independent color space, and a third table that indicates a correspondence relation between a signal value of a first special color that is a color other than cyan, magenta, yellow, and black in the CMYK color space and signal values of cyan, magenta, yellow, and black when the first special color is represented using cyan, magenta, yellow, and black;a converter that converts first image data defined by the input signal value to second image data defined by the output signal value of the CMYK color space using the first table and the second table; anda changer that changes, in forming a mixed color represented by mixing at least two inks of a cyan ink, a magenta ink, a yellow ink, and a black ink, based on the second image data, the second image data such that at least a portion of the cyan ink, the magenta ink, the yellow ink, and the black ink is replaced with a first special color ink that has the first special color using the third table.2. The image data creating device according to claim ...
