Abstract: A color adjustment apparatus includes a processor configured to: acquire desired color measurement value information about a target display by inputting a medium color measurement value of a target printing medium and spectral distribution characteristics of a specific color on the target display to a color measurement value calculation model that has been trained, using learning data including a combination of a medium color measurement value obtained by measuring a specific color on a printing medium, display color measurement value information indicating a display color measurement value obtained by measuring the specific color on a display that has been adjusted to be displayed as a color equivalent to the specific color on the printing medium, and spectral distribution characteristics of the specific color on the display before the adjustment is performed, based on the medium color measurement value of the printing medium and the spectral distribution characteristics of the display, to output the desired

Abstract: An image processing apparatus includes a receiver and a correcting unit. The receiver receives a first read value and a second read value. The first read value indicates a result of reading a first color by a reader from a recording medium in which the first color is applied to a first area in which in-plane density unevenness is confirmable within the recording medium. The second read value indicates a result of reading a second color by the reader. The second color is different from the first color and is applied to a second area that is substantially the same as the first area in a superimposed manner. The correcting unit corrects in-plane density unevenness of the second color applied to the first color in the superimposed manner based on the first read value received by the receiver and the second read value received by the receiver.
