Abstract
An ink jet printing apparatus enables a printing operation to be performed for both surfaces of a printing medium with the use of an ink jet head for ejecting ink. The apparatus comprises components for designating either a both surface printing mode or a one surface printing mode, for applying processing liquid to the printing medium, for reducing a quantity of ejection of ink to the printing medium, and for designating either the component for applying processing liquid or that for reducing ejection quantity in the case that the both surface printing mode is designated. Even in the case that the both surface printing mode is selected, the ink jet printing apparatus assures that excellent printing quality can always be maintained by selecting either of a processing liquid usage printing mode for applying processing liquid to the printing medium or a low density printing mode for reducing a quantity of ejection of ink to the printing medium in excess of the original ink ejecting quantity corresponding to image information.
