ABSTRACT:
Ink, ink sets, and methods of printing are provided. The inks can include a plurality of dyes such that upon printing on a print medium, the printed ink or inks can maintain a neutral color, defined by an a* value from about −1 to about 3 and having a b* value from about 3 to about −15. This neutral color can be maintained such that the printed ink or image has these a*b* values for substantially all L* values ranging from about 25 to about 75, or even from 0 to 95.
