  • Patent number: 11020983
    Abstract: Provided is a liquid ejecting device that includes an ejecting unit configured to eject liquid and a control unit that performs control to apply the liquid to a medium. The ejecting unit is configured to eject, as the liquid, ink, that contains a color material, and inhibitor for inhibiting penetration of the color material into the medium. The control unit is configured to select a first printing mode in which applying the ink to the medium without applying the inhibitor to the medium, and a second printing mode in which applying the inhibitor to the medium and applying the ink to the medium applied with the inhibitor. The control unit causes an amount of the ink applied per unit area in the second printing mode to be smaller than an amount of the ink applied per unit area in the first printing mode.
