Abstract: An image processing apparatus caused to perform controlling for making a first lightness compression ratio of a first image region higher than a second lightness compression ratio of a second image region based on a setting for printing an image using a spot color that is different from process colors being set, the first image region not corresponding to the spot color in the image, and the second image region corresponding to the spot color in the image, and controlling for displaying the image after the first controlling is executed.

Abstract: An image processing apparatus acquires, with respect to a pixel of interest, a combination of a plurality of pixel values representing respective ink application amounts of a plurality of color inks including at least one basic color ink and a fluorescent ink containing a dispersion element having a fluorescent property, determines whether a total value of the plurality of pixel values is larger than a threshold value, and, in a case where it is determined that the total value is larger than the threshold value, reduces a pixel value for at least one ink of the at least one basic color ink in such a manner that an amount by which to reduce a pixel value for the fluorescent ink becomes smaller than an amount by which to reduce a pixel value corresponding to at least one ink of the at least one basic color ink.
