摘要:
An ink set including at least three colors of inks of yellow ink with a hue angle ∠H°, as defined in CIELAB color space on a recording medium, in the range of about 80° to about 110°, magenta ink with a hue angle ∠H° in the range of about 330° to about 360°, and cyan ink with a hue angle ∠H° in the range of about 230° to about 260°, and the following ink (A) and ink (B): ink (A): ink with a hue angle ∠H° in the range of about 0° to about 80°; and ink (B): ink with a hue angle ∠H° in the range of about 0° to about 80° (where the ink (A) has higher saturation and lower brightness than the magenta ink, and the ink (B) has higher saturation and higher brightness than the magenta ink and higher saturation and lower brightness than the yellow ink, and the hue angle (∠H°) is determined as hue angle ∠H°=tan−1(b*/a*)+180 (when a* 0), a* and b* representing the perceived chromaticity index as defined in CIELAB color space).
