An ink set contains white ink and color ink, wherein the difference in static surface tension between the white ink and the color ink is 1.0 mN/m or less and each difference in dynamic surface tension between the white ink and the color ink at each bubble life time of 15 msec, 150 msec, and 1,500 msec at 25 degrees C. is 1.0 mN/m or less as measured by maximum bubble pressure technique. |
