A region to be covered by a cover plate on an ejection opening forming surface of an ink-jet head or an ink-jet head to which the cover plate is installed are determined, on a basis of content of a rebounding mist generated upon ejection of an ink and a processing liquid in overlaying fashion. By this, in the ink-jet printing apparatus performing printing by ejecting the ink and the processing liquid for making the ink insoluble, deposition of the insoluble substance contained in the rebounding mist generated upon ejection of an ink and a processing liquid in overlaying fashion can be successfully prevented.
