Abstract
Disclosed are an inkjet printing method and an inkjet printer capable of printing high-quality images by the inkjet printing method even when ink is exchanged for ink having a different density, particularly ink having a lower density. A printer using this method identifies the type of an ink tank attached to a printhead. When the printer detects in accordance with the type of an ink tank that an ink tank is changed to another ink tank containing ink with a different density, recovery conditions for the printhead are changed in accordance with the type of the ink. Especially when an ink tank is exchanged for another ink tank containing ink with a lower density, the printer increases the number of times of suction for the printhead after the ink tank exchange and the number of times of preliminary discharge after wiping. The printer also shortens preliminary discharge intervals and increases the number of preliminary discharge times at the time of printing.
