Printing method and printing system

摘要

A printing method according to the present invention includes an applying step of applying a curable resin-containing ink onto a transfer sheet (10), a heating and thickening step of heating the ink on the transfer sheet (10) to increase viscosity of the ink, a transfer step of transferring the ink on the transfer sheet (10) to a printing target (15), and a curing step of curing the ink on the printing target (15).

1. A printing method comprising:
an applying step of applying an ink containing a curable resin and a solvent onto a first surface of a transfer sheet, wherein the transfer sheet is elastically deformable along a shape of a printing surface of a printing target; a heating and thickening step of heating the ink on the transfer sheet to increase viscosity of the ink, wherein the heating and thickening step comprises a step of evaporating the solvent from a first surface of the ink to be in contact with the printing target to result a viscosity gradient in the ink, such that the viscosity is higher at the first surface of the ink than at a second surface of the ink in contact with the transfer sheet, and wherein the heating and thickening step further comprises a step of directly heating a second surface of the transfer sheet, which is opposite to the first surface of transfer sheet; a transfer step of directly or indirectly transferring the ink on the transfer sheet to the printing target after the viscosity gradient in the ink is resulted, wherein the transfer step comprises a step of pressing the first surface of the transfer sheet on the printing target using a pressing member, and the pressing member and the transfer sheet are elastically deformed along the shape of the printing surface of the printing target while the transfer sheet is pressed; and a curing step of curing the ink on the printing target.
