Abstract
An ink set contains a white ink composition containing a white coloring material and a resin, and a non-white ink composition containing a non-white coloring material and a resin. The white ink composition and the non-white ink composition are used with a treatment liquid containing a coagulant for coagulating a component of the non-white ink composition. When a 5% by mass calcium acetate monohydrate aqueous solution and each of the ink compositions are mixed, a ratio of the viscosity increase after the mixing to the viscosity increase before the mixing is lower in the white ink composition than in the non-white ink composition.
