发明名称 INK SET
摘要 <p>The invention is to provide an ink set capable of satisfying granularity suppression, false contour suppression, prismatic light suppression, color reproducibility and gloss during recording. The ink set, includes at least three colors of ink consisting of a yellow ink, in which the hue angle ˆ H° defined in the CIELAB color space on a recording medium is within the range of about 80°C to about 110°C, magenta ink, in which the hue angle ˆ H° is within the range of about 330° to about 360°, and a cyan ink, in which the hue angle ˆ H° is within the range of about 230° to about 260°, and the following ink (A) and the following ink (B): ink (A) : ink in which the hue angle ˆ H° is within the range of about 0° to about 80°; and, ink (B) : ink in which the hue angle ˆ H° is within the range of about 0° to about 80° (wherein, the ink (A) has higher chroma and lower brightness than the magenta ink, the ink (B) has higher chroma and higher brightness than the magenta ink and has higher chroma and lower brightness than the yellow ink, the hue angle (ˆ H°) is determined according to ˆ H° = tan -1 (b*/a*) + 180 (when a*<0) or according to ˆ H° = tan -1 (b*/a*) + 360 (when a*>0), and a* and b* represent a perceptive chromaticity index in the CIELAB color space).</p>
