Abstract
An ink set includes a process color ink set including a yellow ink, a magenta ink, a cyan ink, and a black ink as process color inks, and a light ink having a color similar to a corresponding one of the process color inks in the process color ink set. The yellow ink, the magenta ink, and the cyan ink each have a maximum absorption wavelength, and each have a full width at half maximum of a peak including the maximum absorption wavelength. A maximum absorbance in a visible light wavelength range of the light ink is 70% or less of a maximum absorbance in the visible light wavelength range of the corresponding one of the process color inks.
