摘要： An ink jet printing apparatus and an image processing apparatus capable of stably outputting an image with no joint streak even in the case where printing conditions, such as the kind of ink and the kind of printing medium, change in a variety of ways are provided. For this purpose, correction processing is performed on image data corresponding to an eject port group located at one end part of an eject port column in a first printing scan and on image data corresponding to an eject port group located at the other end part in a second printing scan. At this time, the number of eject ports included in a first eject port group and the number of eject ports included in a second eject port group are adjusted in accordance with printing conditions.

摘要： A printing apparatus that includes nozzle arrays, formed of nozzles for ejecting ink of the first to fourth ink color groups, and that scans a print medium while moving the nozzle arrays to perform printing. For printing a unit area of a print medium, where printing is to be completed by performing a plurality of scans, the printing apparatus performs a plurality of scans, and conveys, between movements, a print medium a predetermined amount, which is equivalent to the width of the unit area. Then, to perform a plurality of scans using the nozzle arrays for the first to fourth ink color groups, print data are generated, so that for the nozzle arrays that belong to two ink color groups, the nozzle array for the first ink color group is employed to eject ink into the unit area prior to the nozzle array for the second ink color group.
摘要翻译：一种打印装置，包括由用于喷射第一至第四墨水颜色组的墨水的喷嘴形成的喷嘴阵列，并且在移动喷嘴阵列进行打印的同时扫描打印介质。为了打印要通过执行多次扫描来完成打印的打印介质的单位区域，打印装置执行多次扫描，并且在运动之间传送打印介质预定量，其等于单位面积的宽度。然后，为了使用第一至第四墨水颜色组的喷嘴阵列执行多次扫描，产生打印数据，使得对于属于两个墨水颜色组的喷嘴阵列，第一墨水颜色组的喷嘴阵列为用于在用于第二油墨颜色组的喷嘴阵列之前将油墨喷射到单元区域中。
