Claim:
1. A printing method, comprising: a printing-ink applying process of applying a printing ink onto a transfer sheet capable of transmitting an ultraviolet light, and the printing ink is pigment-based and composed of a solvent UV ink or an UV ink; a printing-ink layer forming process of irradiating the printing ink being applied with the ultraviolet light while heating the printing ink, in a state where the printing ink is the solvent UV ink, but irradiating the printing ink being applied with the ultraviolet light in a state where the printing ink is the UV ink, such that the printing ink is cured to form a printing ink layer; a bonding-ink applying process of applying a bonding ink onto the printing ink layer, and the bonding ink is composed of the solvent UV ink or the UV ink for bonding the printing ink layer to a medium; a bonding-ink layer forming process of performing irradiation with the ultraviolet light from an opposite surface of the transfer sheet to a surface having the printing ink layer formed thereon, in a state where the bonding ink has been pressed against the medium, such that the bonding ink is completely cured to form a bonding ink layer; and an ink-layer transferring process of peeling off the transfer sheet from the printing ink layer to transfer the printing ink layer onto the medium, and the ink-layer transferring process is performed after the bonding-ink layer forming process.
