Abstract
Abstract There are provided a plain paper mode in which printing is performed on a plain paper and a special medium mode in which printing is performed on a special printing medium having a coat layer formed thereon. In the plain paper mode, Bk ink using both self-dispersing type pigment and dye as coloring materials is ejected from a Bk head , then a processing liquid with a high penetrability which insolubilizes the above coloring materials is ejected from a S head. On the other hand, in the special medium mode, the above Bk ink is ejected from the Bk head, but no processing liquid is ejected from the S head. As a result, this enables the improvement in a print quality, such as OD level, and a high-speed fixing in ink-jet printing in either case where a printing medium having a coat layer formed thereon is used or where the plain paper is used.

Claims Analysis
Total Claims: 30
Claim 1
Independent Claim
120 words
1 . An ink printing method of applying ink containing at least a pigment as a coloring material onto a printing medium to perform printing, said method comprising the steps of: providing a plurality of printing modes to be set corresponding to mode setting information, the plurality of printing modes including a printing mode for applying the ink and a processing liquid for promoting solidification of the coloring material in said ink onto the printing medium and a printing mode for applying no processing liquid but the ink onto the printing medium; and selecting one mode corresponding to the mode setting information among the plurality of printing modes in accordance with a type of the printing medium to perform printing.
