Abstract:
1. A method for printing a non-aqueous ink onto a printing substrate, using a non-aqueous ink comprising a coloring material and a non-aqueous solvent, wherein the non-aqueous ink has a total surface free energy, calculated from a Kaelble-Uy theoretical formula, of 25 to 30 mN/m, and a dispersive component ratio represented by a formula (1) shown below of 0.55 to 0.75, and the printing substrate has a coating layer comprising inorganic particles, has a total surface free energy, calculated from a Kaelble-Uy theoretical formula, of 30 to 50 mN/m, has a dispersive component ratio represented by the formula (1) of 0.80 to 1.0, and exhibits a liquid absorption property for the inorganic particles, represented by a formula (2) shown below, of 0.30 or greater: wherein the oil absorption represented by B refers to a value obtained in accordance with a linseed oil absorption measurement method prescribed in JIS K5101-21, and the specific surface area represented by C refers to a value obtained by a method of measuring specific surface area using a BET method.
