Abstract:
A printing apparatus includes a printing unit discharging a plurality of different pigmented inks onto a transfer member and forming an ink image, a processing unit performing processing such that each of the pigmented inks applied on the transfer member forms a layer, and a transfer unit transferring the ink image from the transfer member onto the printing medium conveyed by the conveyance unit. The pigmented inks include cyan, magenta, yellow, and black inks as pigmented inks of four basic colors, and at least one pigmented ink different from the pigmented inks of basic colors. A first ink at least one of the pigmented inks of the basic colors is applied onto the transfer member after a second ink is applied. The second ink is the pigmented ink different from the pigmented inks of the basic colors and has a color material density lower than that of the first ink.
