Abstract
An ink jet printing apparatus, an ink jet printing method, and a data generating apparatus are provided in which an image performance such as an abrasion resistance can be improved and a printing head can have a longer life by ejecting processing liquid at an appropriate time. The processing liquid is ejected, to a predetermined area on a printing medium in which the formation of a image by ink is completed, from a printing head in two or more scannings in five scannings of the printing heads.
Claims14
A printing apparatus for causing a printing head to perform a plurality of printing scannings over a predetermined area of the printing medium, the print head being capable of ejecting an ink and a processing liquid for covering an image formed by the ink on the printing medium, the printing apparatus comprising:
- an obtaining unit configured to obtain an ink ejection data representing an ejection or non-ejection of ink to the predetermined area in each of the plurality of printing scannings;
- a detection unit configured to detect an order of a final scanning at which the ink is finally ejected to the predetermined area based on the ink ejection data obtained by the obtaining unit;
- and
- a determining unit configured to determine an order of scanning at which the processing liquid is ejected among the plurality of printing scannings on the predetermined area, based on the order of the final scanning in the plurality of printing scannings detected by the detecting unit.
A printing method for causing a printing head to perform a plurality of printing scannings over a predetermined area of the printing medium, the print head being capable of ejecting an ink and a processing liquid for covering an image formed by the ink on the printing medium, the printing method comprising the steps of:
- obtaining an ink ejection data representing an ejection or non-ejection of ink to the predetermined area in each of the plurality of printing scannings;
- detecting an order of a final scanning at which the ink is finally ejected to the predetermined area based on the ink ejection data obtained in the obtaining step;
- and
- determining an order of scanning at which the processing liquid is ejected among the plurality of printing scannings on the predetermined area, based on the order of the final scanning in the plurality of printing scannings detected by the detecting unit.
