Printing method and printing apparatus using ink and treatment liquid

A printing method, scanning a printing medium for ejecting first and second liquids on said printing medium for printing an image of said second liquid on said printing medium, said printing method comprising:

• a step of variably setting an ejection amount of said first liquid in one scan depending upon a number of scans for a same region of said printing medium and a number of times said second liquid is ejected for a same dot in said same region,
• wherein, the amount of the first liquid elected in the one scan is set to smaller amounts in correspondence to fewer numbers of scans.

A printing apparatus, scanning a printing medium for ejecting first and second liquids on said printing medium for printing an image of said second liquid on said printing medium, said printing apparatus comprising:

• means for variably setting an ejection amount of said first liquid in one scan depending upon a number of scans for a same region of said printing medium and a number of times said second liquid is ejected for a same dot in said same region,
• wherein, the amount of the first liquid elected in the one scan is set to smaller amounts in correspondence to fewer numbers of scans.

A printing method for printing an image on a printing medium by ejecting a first liquid and a second liquid from a printing head to said printing medium while relatively scanning said printing head and said printing medium, the method comprising:

• ejecting said first liquid and said second liquid from said printing head to said printing medium depending upon a printing mode selected from among a plurality of printing modes in which a number of scans for a same region on said printing medium is different for each printing mode;
• wherein, an ejection ratio of said first liquid to a number of ink dots ejected for all scans of the printing medium in the printing mode selected is smaller in correspondence to fewer numbers of scans.

A printing apparatus having means for printing an image on a printing medium with ejecting a first liquid and a second liquid from a printing head to said printing medium while relatively scanning said printing head and said printing medium, comprising:

• printing means for ejecting said first liquid and said second liquid from said printing head to said printing medium depending upon a printing mode selected from among a plurality of printing modes in which a number of scans for a same region of said printing medium is different for each printing mode,
• wherein, an ejection ratio of said first liquid to a number of ink dots ejected for all scans of the printing medium in the printing mode selected is smaller in correspondence to fewer numbers of scans.
