摘要

Printing an image on a printing medium includes using a print head that ejects a first ink and a second ink having higher lightness than the first ink with preliminary ejection that is performed in a predetermined area in which the image is to be formed in order to maintain an ink ejection state of the print head and that does not contribute to printing of the image, wherein dots of the first ink and dots of the second ink formed in the predetermined area by the preliminary ejection are printed so as to be superposed on each other.

主权项

1. A method of printing an image on a printing medium using a print head ejecting a first ink, a second ink having higher lightness than the first ink, and a third ink having lower lightness than the second ink, the method comprising:
preliminarily ejecting the first ink in a predetermined area; preliminarily ejecting the second ink in the predetermined area; preliminarily ejecting the third ink in the predetermined area; and ejecting ink in the predetermined area to form the image, wherein preliminarily ejecting the first ink, the second ink and the third ink is performed to maintain an ink ejection state of the print head without contributing to image formation, wherein dots of the first ink and dots of the second ink formed in the predetermined area by the preliminary ejection are printed to be superposed on each other, and wherein the dots of the second ink and dots of the third ink formed in the predetermined area by the preliminary ejection are printed not to be superposed on each other.
