Abstract:
An ink jetting ink set includes an ink composition for recording supplied to and used in an ink flow path and containing at least one of a glitter pigment and a metal oxide as a coloring material, and an auxiliary ink composition used in cleaning of the ink flow path, in which, in cases where a dynamic viscosity at 20° C. in the ink composition for recording is η1 (mm2/s) and a surface tension at 20° C. is γ1 (mN/m), and the dynamic viscosity at 20° C. in the auxiliary ink composition is η2 (mm2/s) and the surface tension at 20° C. is γ2 (mN/m), the following formula (1) and the following formula (2) are satisfied at the same time. η1≦η2 (1) γ1≧γ2 (2)
