摘要：
For providing an ink composition which can reduce matamerizm while reducing the total amount of inks used when such ink composition is simultaneously used with another ink composition, and prevent reduction of the image quality, the present invention provides an ink composition wherein the difference between the maximum value and the minimum value of the reflectance of an output color through an ink jet output over a light source wavelength range of 400 to 700 nm, in which such output color satisfies formulae (1), (2) and (3) below at a spatial coordinate (L* a* b*) stipulated by CIE under the D 50 light source is not more than 20%: (1) 45≦L*≦55 (2) −10
