To provide an ink set that can effectively prevent blurred printing even though the ink set is composed of a plurality of ink compositions containing deep-color ink and pale-color ink.SOLUTION: An ink set contains a colorant and an organic solvent. The ink set contains a plurality of nonaqueous ink compositions to be discharged by the inkjet technique. The ink set contains a deep-color ink and a pale-color ink having a smaller colorant content than that of the deep-color ink. At least one of the plurality of nonaqueous ink compositions contained in the ink set contains an organic solvent A (at least one of predetermined alkylamide solvents and predetermined cyclic amide solvents).SELECTED DRAWING: None 【課題】濃色インクと淡色インクを含む複数のインク組成物からなるインクセットであっても印字の滲みを効果的に抑制することのできるインクセットを提供する。【解決手段】色材と、有機溶剤と、を含有し、インクジェット法によって吐出される複数の非水性インク組成物を含むインクセットであって、濃色インクと、該濃色インクよりも色材の含有量が少ない淡色インクと、を含み、前記インクセットに含まれる複数の非水性インク組成物のうち少なくとも１つの非水性インク組成物は、有機溶剤Ａ（所定のアルキルアミド系溶剤及び所定の環状アミド系溶剤のうち少なくとも１つ）を含有する、インクセット。【選択図】なし
