ABSTRACT:
An ink-jet recording apparatus of the present invention is for eliminating the difference in printed results generated from an offset between the positions to which a main drop and satellite drop of ink are discharged respectively, and generated also from the difference in the ejecting order of processing liquid with respect to ink. The apparatus is constructed such that in a scanning operation in which a satellite ink drop Da2 is dropped onto a main ink drop Da1 ejected from the ink head section in a superimposed manner, the processing liquid Sa falls after the ink dot formed on the recording paper 16 is expanded to some extent, whereas in a scanning operation in which the satellite drop Db2 is dropped at a position offset from the position of the main drop Db1, the processing liquid Sb is first ejected, and those ink drops Db1 and Db2 are discharged thereafter, so as to suppress expansion of the ink dot, making thus a dot having substantially the same size with that formed in the above scanning case.
