<p>Upon performing printing using a dye ink and a pigment ink and in addition a treatment liquid making those inks insoluble, two kinds of inks consisted of the pigment ink (Ip) and the dye ink (Id) are used. After applying the pigment ink (Ip) on a printing medium (P), the dye ink (Id) is applied overlaying with the pigment ink. After mixing these inks on the printing medium (P), the treatment liquid (S) which makes the inks insoluble, is applied. In the alternative, a mixed ink (Im) in which a pigment ink not requiring a dispersant and the dye, is used. After application of this mixed ink (Im) on the printing medium (P), the treatment liquid (S) which makes the ink (Im) insoluble, is applied. Therefore, problem of "crack", "soaking out", "overflow" or lowering of OD value which can be caused upon reaction of the pigment ink (Ip) and the dye ink (Id) or the mixed ink (Im) with the treatment liquid (S), can be solved to achieve high quality printing. <IMAGE></p> |
