Abstract
An ink set includes four types of inks that are a yellow ink, a magenta ink, a cyan ink, and a black ink. Each of the four types of inks contains water and a colorant, and at least one of the four types of inks contains an ultraviolet absorber. When Abs (Y) represents the absorbance of the yellow ink, Abs (M) represents the absorbance of the magenta ink, Abs (C) represents the absorbance of the cyan ink, and Abs (K) represents the absorbance of the black ink with respect to light with a wavelength of 385 nm, the ratios of Abs (Y), Abs (M), and Abs (C) to Abs (K) satisfy predetermined conditions.
