  • Patent number: 10562330
    Abstract: A printing mode for performing printing to a printing medium and a determination mode for determining the application amount of a reaction liquid to a discharge medium can be performed. In the determination mode, a reaction liquid application unit forms a layer of the reaction liquid on the discharge medium, and then an ink application unit applies an ink onto a part of the layer to form a test pattern to be utilized for the determination. In the formation of the test pattern, an image to be formed by the ink by the aggregation of a solid content in the applied ink partially moves and shrinks on the layer of the reaction liquid to be thereby deformed with a grade according to the applied reaction liquid.
