Abstract
A preliminary process for ejecting an ink after ejecting a processing liquid on a printing medium and a post-process for ejecting the processing liquid after ejecting the ink on the printing medium are distinguished. In one preferred mode, when a preliminarily process portion, in which an ink dot is formed after formation of a processing liquid dot, and a post-process portion, in which the processing liquid dot is formed after formation of the ink dot are present in admixing fashion, an ejection amount of the ink per unit area in the post-process portion is made smaller than the ejection amount of the ink per unit area in the preliminarily process portion. By this, a difference of printing quality in the preliminarily process portion and the post-process portion on the printing medium can be made smaller.
