Abstract
A water-based ink set for ink-jet recording is provided which is capable of: reducing graininess in a low-density printed part in a cyan direction without reducing the color reproduction range in the cyan direction in a high-density printed part; extending the color reproduction range in a blue direction and/or a green direction; and improving gas resistance and the vividness in the blue direction and/or the green direction. The water-based ink set for ink-jet recording includes a cyan dye ink employing dye as a coloring agent and a blue pigment ink employing pigment as a coloring agent and/or a green pigment ink employing pigment as a coloring agent. The cyan dye ink is a light cyan dye ink having a lightness (L*) of about 60 or more in the L*a*b* colorimetric system.
