Abstract:
An ink jet print apparatus using an ink jet head that ejects different liquids, which are an ink and a processing liquid, from at least two ejection ports to allow the different liquids sequentially ejected from the at least two ejection ports while the ink jet head and a printing medium are relatively moved to deposit on the printing medium in such a way that the ejected different liquids are deposited on one another on the printing medium for printing,wherein a velocity vector of one of the different liquids ejected from at least one port for subsequent ejection of the at least two ejection ports while relatively moving the ink jet head and the printing medium has a velocity vector component in a direction opposite to the moving direction of the ink jet head relative to the printing medium and has the velocity vector component in the direction opposite to the moving direction larger than the velocity vector component of the liquid first ejected from the at least one ejection port while relatively moving the ink jet head and the printing medium.
