A printing method for performing inkjet printing using a medium, the printing method comprising steps of: ejecting ink to the medium from an inkjet head while moving the inkjet head in a main scanning direction which is orthogonal to a transport direction of the medium and adhering the ink to the medium, the ink including a colorant, an ultraviolet absorbent, a resin, and an aqueous solvent that emulsifies or suspends the resin; and irradiating the ink adhered to the medium with ultraviolet light using an ultraviolet light source and changing irradiation intensity of the ultraviolet light source to heat the ink to a temperature lower than a boiling point of the ink and high enough to prevent the ink from bleeding, so that the aqueous solvent is at least in part volatilized and removed from the ink; the ultraviolet light source is disposed at positions adjacent to the inkjet head in a main scanning direction, and the ultraviolet radiation from the ultraviolet light source starts immediately after the inkjet head passed a respective one of positions on the medium, so that ultraviolet light is selectively absorbed by the ink that already landed on the medium alone; the ultraviolet absorbent including no material that triggers the polymerization of monomer or oligomer in response to ultraviolet light; the ultraviolet absorbent generating heat when the ink is irradiated with the ultraviolet light, and the generated heat rapidly dries the ink by volatilizing and removing the aqueous solvent from the ink; characterized in that the aqueous solvent includes water and a water-soluble organic solvent, and the ink adhered to the medium is irradiated with ultraviolet light from the ultraviolet light source and heated to a temperature lower than 100°C. ejecting ink to the medium from an inkjet head while moving the inkjet head in a main scanning direction which is orthogonal to a transport direction of the medium and adhering the ink to the medium, the ink including a colorant, an ultraviolet absorbent, a resin, and an aqueous solvent that emulsifies or suspends the resin; and irradiating the ink adhered to the medium with ultraviolet light using an ultraviolet light source and changing irradiation intensity of the ultraviolet light source to heat the ink to a temperature lower than a boiling point of the ink and high enough to prevent the ink from bleeding, so that the aqueous solvent is at least in part volatilized and removed from the ink; the ultraviolet light source is disposed at positions adjacent to the inkjet head in a main scanning direction, and the ultraviolet radiation from the ultraviolet light source starts immediately after the inkjet head passed a respective one of positions on the medium, so that ultraviolet light is selectively absorbed by the ink that already landed on the medium alone; the ultraviolet absorbent including no material that triggers the polymerization of monomer or oligomer in response to ultraviolet light; the ultraviolet absorbent generating heat when the ink is irradiated with the ultraviolet light, and the generated heat rapidly dries the ink by volatilizing and removing the aqueous solvent from the ink; characterized in that the aqueous solvent includes water and a water-soluble organic solvent, and the ink adhered to the medium is irradiated with ultraviolet light from the ultraviolet light source and heated to a temperature lower than 100°C. the ultraviolet light source is disposed at positions adjacent to the inkjet head in a main scanning direction, and the ultraviolet radiation from the ultraviolet light source starts immediately after the inkjet head passed a respective one of positions on the medium, so that ultraviolet light is selectively absorbed by the ink that already landed on the medium alone; the ultraviolet absorbent including no material that triggers the polymerization of monomer or oligomer in response to ultraviolet light; the ultraviolet absorbent generating heat when the ink is irradiated with the ultraviolet light, and the generated heat rapidly dries the ink by volatilizing and removing the aqueous solvent from the ink; characterized in that the aqueous solvent includes water and a water-soluble organic solvent, and the ink adhered to the medium is irradiated with ultraviolet light from the ultraviolet light source and heated to a temperature lower than 100°C.
