Abstract

A set according to an embodiment of the present disclosure includes a treatment solution composition that contains particles containing organopolysiloxane, and water, an ink jet ink composition that contains a pigment and water, and a reaction solution that contains an aggregating agent causing aggregation of a component of the ink jet ink composition, and water. A relation between a static surface tension (mN/m) of the reaction solution, a static surface tension (mN/m) of the ink jet ink composition, and a static surface tension (mN/m) of the treatment solution composition satisfies (the static surface tension of the reaction solution)<(the static surface tension of the ink jet ink composition)≤(the static surface tension of the treatment solution composition). The static surface tension of the reaction solution is from 25 to 40 mN/m. The treatment solution composition, the ink jet ink composition, and the reaction solution are discharged by an ink jet method and used.
