摘要： Provided is an ink set including standard ink and light ink. Standard ink includes cyan, magenta, and yellow inks. Light ink includes a light cyan or light magenta ink, or both. The pigment concentration in cyan ink is 1.9% by mass or greater but 3.6% by mass or less. The pigment concentration in light cyan ink is 0.4% by mass or greater but 1.4% by mass or less. The pigment concentration in magenta ink is 1.9% by mass or greater but 3.6% by mass or less. The pigment concentration in light magenta ink is 0.4% by mass or greater but 1.4% by mass or less. The light ink contains water, organic solvent, and resin. The organic solvent contains amide compound represented by General formula (1). In General formula (1), R1, R2, and R3 each represent a hydrocarbon group containing from 1 through 8 carbon atoms.
