A method for recording on a recording medium by discharging a non-aqueous ink containing a non-aqueous solvent and a pigment by an inkjet system. The method contains a step of preparing recording paper having a thickness exceeding 0.083 mm as a recording medium, a step of obtaining a volume Vm and a thickness Tm of the recording paper, a step of obtaining a volume Vs of a solvent that is capable of being retained by the recording paper by using a solvent having a vapor pressure at 25° C. of 0.001 mmHg or less and a specific gravity of from 0.800 to 1.200, a step of obtaining a solvent absorptivity Asl. (%) of the recording paper by the following equation (1):Asl.=(Vs/Vm)×100 (1)a step of obtaining an allowable ink amount VI (pl/m2) per unit area of the recording paper by the following equation (2):VI=(Tm−0.083)×Asl.×1012 (2)and a step of discharging the non-aqueous ink in an amount Vd (pl/m2) satisfying the following equation (3) by an inkjet system:Vd≦VI.
