A printing apparatus includes an ejection head including a first nozzle row configured to eject, toward a recording medium, a first liquid containing a photopolymerization initiator and a second nozzle row configured to eject, toward the recording medium, a second liquid containing the polymerizable compound and a color material and not containing the photopolymerization initiator, a driving unit configured to change relative positions of the ejection head and the recording medium, and an irradiation unit configured to irradiate, with the light, the recording medium onto which the first liquid and the second liquid are deposited. The first liquid and the second liquid are ejected from the ejection head so that the second liquid overlaps the first liquid on a surface of the recording medium. A distance between the irradiation unit and the first nozzle row is longer than a distance between the irradiation unit and the second nozzle row.
