Abstract

See full text

In a color mode, the image quality improving liquid is set to the same rate of 20% for all input signal values. Meanwhile, in a monochrome mode, the image quality improving liquid is set to a rate of 30% in the highlight region, and the ink rate gradually decreases starting from the intermediate tones and proceeding towards the high-density region. Thus, the optimal printing method and usage rate for image quality improving liquid can be adjusted in accordance with the image quality characteristics of the color mode and the monochrome mode. As a result, it is possible to reduce color change in specular light while maintaining at least a certain level of image clarity in both modes, and thus favorably print both color images and monochrome images.
