Publication number: 20210237477Abstract: A printing apparatus includes a conveyance unit, a printing unit, and a heating unit that heats a print medium. The conveyance unit conveys the print medium such that the printing unit can print an image onto a second print region at a printing position when the heating unit can heat a first print region at a heating position. If the ink amount applied to the first print region is a first amount, an image is printed onto the second print region in a first mode. If the applied ink amount is a second amount larger than the first amount, an image is printed onto the second print region in a second mode. A time for which the first print region passes through the heating position in the second mode is longer than a time for which the first print region passes through the heating position in the first mode.Type: ApplicationFiled: January 29, 2021Publication date: August 5, 2021Inventors: Rie Takekoshi, Takayuki Ushiyama, Keita Ishimi, Tatsuo Shimmoto, Masaya Uetsuki
