Abstract
An ink set for ink-jet recording of the present invention includes a black ink which has a surface tension of not less than 40 mN/m at 25° C., and a color ink which has a surface tension of not less than 40 mN/m at 25° C. The viscosity ratio of the color ink with respect to the black ink is not less than 1.3. The feathering of the ink is avoided, and the bleeding, which would otherwise appear at the boundary between the black ink and the color ink, is avoided.
