Ink jet printing apparatus and ink jet printing method

A printing method of performing printing on a print medium by executing an operation of causing a print head to eject inks while scanning the print head multiple times over the same area of the print medium in a reciprocating manner and an operation of feeding the print medium in a direction different from that in which the print head is scanned, said method comprising the steps of:

• obtaining information on the width of the print medium used for printing or a print width corresponding to print data;
• and
• changing the number of multi-scans of the print head in accordance with the information obtained in said obtaining step,
• wherein if the information obtained in said obtaining step indicates a width equal to or larger than a predetermined value, the number of the multi-scans is increased in said changing step.

A printing apparatus which performs printing on a print medium by executing an operation of causing a print head to eject inks while scanning the print head multiple times over the same area of the print medium in a reciprocating manner and an operation of feeding the print medium in a direction different from that in which the print head is scanned, said apparatus comprising:

• obtaining unit configured to obtain information on the width of the print medium used for printing or a print width corresponding to print data;
• and
• determining unit configured to determine the number of multi-scans of the print head in accordance with the information obtained by said obtaining unit,
• wherein said determining unit determines a predetermined number as the number of the multi-scans if the information obtained by said obtaining unit indicates a width smaller than a predetermined width, and
• wherein said determining unit determines a number larger than the predetermined number as the number of the multi-scans if the information obtained by said obtaining unit indicates a width equal to or larger than the predetermined width.
