PROBLEM TO BE SOLVED: To print a desired printed matter by a method wherein a uniform dot diameter is obtained on a synthetic resin base material by ink jet printing. SOLUTION: This printed matter is obtained by executing an ink jet printing with an active energy ray curing type ink, which includes a pigment, a two or more ethylenic double bond-containing compound and a one ethyhlenic double bond-containing compound, has a surface tension of 25 to 40 mN/m and a viscosity of 10 to 50 mPa.s, after the printing surface of a synthetic resin base material is corona-treated or plasma-treated so as to develop the surface free energy of 65 to 72 mN/m. |
