Abstract:
1. A printing method comprising: an application step in which an ultraviolet curable ink is applied to an elastic transfer pad by an ink-jetting, wherein the transfer pad is able to be deformed following the shape of a printing object; a provisional curing step in which provisional curing is performed by irradiating the ultraviolet curable ink applied to the transfer pad with ultraviolet light such that a gradient of viscosity is generated between a surface of the ultraviolet curable ink facing ultraviolet light and a contact surface of the ultraviolet curable ink with the transfer pad, wherein the viscosity of the surface of the ultraviolet curable ink facing ultraviolet light is higher than the viscosity of the contact surface of the ultraviolet curable ink with the transfer pad; a transfer step in which the transfer pad and the printing object are brought into close contact with each other by pressure such that the transfer pad is deformed along a surface shape of the printing object, to thereby transfer the ultraviolet curable ink provisionally cured in the provisional curing step to the printing object; and a final curing step in which final curing is performed by irradiating the ultraviolet curable ink transferred to the printing object with ultraviolet light.
