Abstract
There is provided a printing device that carries out printing with respect to a medium; the printing device including inkjet heads, which are ejection heads that eject an ink to the medium; and an infrared irradiating portion that irradiates an infrared light in which a wavelength is smaller than or equal to 3 μm with respect to the ink on the medium; where the inkjet heads eject the ink containing a solvent that generates heat by absorbing the infrared light; and the infrared irradiating portion volatilizes and removes at least one part of the solvent in the ink by irradiating the infrared light with respect to the ink on the medium.

A printing device that carries out printing with respect to a medium, the printing device comprising:
- an ejection head that ejects an ink to the medium;
- and
- an infrared irradiating portion that irradiates an infrared light in which a wavelength is smaller than or equal to 3 μm with respect to the ink on the medium;
- wherein the ejection head ejects the ink containing a solvent that generates heat by absorbing the infrared light;
- and
- the infrared irradiating portion volatilizes and removes at least one part of the solvent in the ink by irradiating the infrared light with respect to the ink on the medium,
- wherein the infrared irradiating portion generates the infrared light in which a peak wavelength is smaller than or equal to 3 μm, and an intensity of a component in which a wavelength is 4 μm is smaller than or equal to 1/10 of an intensity at the peak wavelength.
A printing method that carries out printing with respect to a medium, the printing method comprising:
- providing an ejection head that ejects an ink to the medium;
- providing an infrared irradiating portion that irradiates an infrared light in which a wavelength is smaller than or equal to 3 μm with respect to the ink on the medium;
- ejecting the ink containing a solvent that generates heat by absorbing the infrared light by the ejection head;
- and
- volatilizing and removing at least one part of the solvent in the ink by irradiating the infrared light with respect to the ink on the medium from the infrared irradiating portion;
- wherein the infrared irradiating portion generates the infrared light in which a peak wavelength is smaller than or equal to 3 and an intensity of a component in which a wavelength is 4 μm is smaller than or equal to 1/10 of an intensity at the peak wavelength.
