To provide an ink set that makes it possible to obtain printed matter having excellent weather resistance and color reproducibility and improved graininess, metamerism and beading, and provide an ink jet recording method, and printed matter.SOLUTION: The ink set for single-pass printing at least includes a cyan ink, a magenta ink, a yellow ink, and a grey ink. The magenta ink satisfies specific conditions regarding spectral reflectance. The grey ink has a spectral reflectance of 20-70% at a wavelength of 500 nm and satisfies the specific conditions regarding the spectral reflectance.SELECTED DRAWING: None 【課題】優れた耐候性、色再現性を有し、かつ、粒状性、メタメリズム、ビーディングの改善された印刷物が得られるインキセット、インクジェット記録方法、及び、印刷物を提供すること。【解決手段】少なくともシアンインキ、マゼンタインキ、イエローインキ、及びグレーインキを含むシングルパス印刷用インキセットであって、前記マゼンタインキが、分光反射率に関する特定の条件を満たし、前記グレーインキが、波長５００ｎｍにおける分光反射率が２０〜７０％であり、かつ、前記分光反射率に関する特定の条件を満たすことを特徴とする、シングルパス印刷用インキセットである。【選択図】なし
