The ink is filled in a printing plate having a concave pattern, transferred to a printing blanket having a silicone rubber sheet on the surface, and then used in an offset printing method in which the ink is transferred from the blanket to a transfer target. When the printing ink contains at least a powder component, a resin component, and a solvent component, the resin component contains an acrylic-styrene type, an acrylic-urethane type, an acrylic-epoxy copolymer, a urethane acrylate, or an epoxy acrylate, and the solvent component is Diethylene glycol monobutyl ether, ethylene glycol monobutyl ether, diethylene glycol dimethyl ether, γ-butyl lactone, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, ethylene glycol monophenyl ether The ether etc. containing one or acids or more.
