Patent ID: 10532587

Abstract:
The printing apparatus performs inkjet printing and includes an inkjet head that ejects ink to a medium, and an ultraviolet irradiator that irradiates the ink on the medium with ultraviolet light so as to heat the ink. The ink contains solvents. The solvents include a low-boiling solvent and a high-boiling solvent having a higher boiling point than the other, and the ink contains 20 wt. % or more of the low-boiling solvent and 20 wt. % or more of the high-boiling solvent. In at least part of a duration of time until the solvents in the ink are completely evaporated, an energy line irradiator irradiates the ink on the medium with an energy line, so that a temperature of the ink on the medium increases to a degree higher than or equal to the boiling point of the low-boiling solvent and lower than the boiling point of the high-boiling solvent.
