Patent ID: 7854798

Claim:
An ink set comprising: a first ink; and a second ink, wherein the first ink has a maximum absorption wavelength in a region of 450 nm or more and less than 500 nm, wherein the second ink has a maximum absorption wavelength in a region of 500 nm or more and 570 nm or less, wherein a B/A ratio is 0.7 or more and 1.0 or less where A is a maximum summed absorbance and B is a minimum summed absorbance of a summed absorption spectrum in a region of 450 nm or more and 570 nm or less, where the summed absorption spectrum is the sum of an absorption spectrum of the first ink and an absorption spectrum of the second ink, and wherein the first ink comprises C.I. Pigment Red 149 as a coloring material and the second ink comprises C.I. Pigment Red 122 as a coloring material.
