The present invention provides an ink set which has a good discharge stability, with which high-definition images are obtained even when printing at high speed, and which is excellent in drying characteristics and thereby it is difficult for offset to occur. n An ink set containing an ink composition containing (a) a pigment, (b) a water-soluble solvent, (c) a surfactant, and (d) water, and a colorless ink composition containing (e) a coagulation accelerator for accelerating the coagulation of the ink composition, and (f) a water-soluble solvent, characterized in that the water-soluble solvent (b) of the ink composition contains 65% by mass or more of a water-soluble solvent having an SP value of 27.5 or less, and the content of the water-soluble solvent (b) in the ink composition is from 30% by mass to 55% by mass, and that the water-soluble solvent (f) of the colorless ink composition contains 90% by mass or more of a water-soluble solvent having an SP value of 27.5 or more. |
