Abstract
Provided are an inkjet printing apparatus and an inkjet printing method in which a high-quality image free of peeling of an image face can be printed, while an amount of a treatment liquid consumed is reduced. For that purpose, a group of pigment-based inks excellent in wettability with respect to the treatment liquid (small in contact angle with respect to the treatment liquid) are made relatively small in a proportion of the treatment liquid applied to a position to which the pigment-based ink concerned is applied. In contrast, a group of pigment-based inks poor in wettability (great in contact angle with respect to the treatment liquid) are made relatively great in a proportion of the treatment liquid applied to a position to which the pigment-based ink concerned is applied.
