Abstract
Official abstract text for this publication.
An ink jet printing apparatus inhibits the temperature of a print head from increasing excessively while preventing significant density or hue unevenness from occurring in images, without the need for a complicated structure or complicated control. Thus, the temperature of the print head is detected, and the number of scans in which the print head is to stand by until start of scanning and a standby time for each of the set number of scans by the print head are set, on the basis of the detected temperature.
First claim
Opening claim text (preview).
What is claimed is: 1. An ink jet printing apparatus comprising: a print head for ejecting ink for printing; a scanning unit configured to scan the print head relative to a print medium; an obtaining unit configured to obtain information relating to a temperature of the print head in a target scan of the print head by the scanning unit; and a control unit configured to control the scanning unit so as to delay scanning of the print head by providing a delay time between a pre…
