Abstract
An ink set includes a water-based coloring ink and a water-based coating liquid having an acting of aggregating the water-based coloring ink, wherein a dynamic surface tension value at 25° C. at a surface life of 100 ms of the water-based coating liquid is smaller than a dynamic surface tension value at 25° C. at a surface life of 100 ms of the water-based coloring ink, a difference between the dynamic surface tension value at 25° C. at a surface life of 100 ms of the water-based coating liquid and the dynamic surface tension value at 25° C. at a surface life of 100 ms of the water-based coloring ink is 5 mN/m or more and 20 mN/m or less, and the dynamic surface tension value at 25° C. at a surface life of 100 ms of the water-based coating liquid is within a range of 20 to 30 mN/m.
