Image processing system, image processing apparatus, image forming apparatus and computer-readable storage medium

A non-transitory computer-readable storage medium to store a program so as to make a computer of an image processing apparatus which generates image data based on an input of a print job to output the generated image data to an image forming apparatus, function as an output section to output color adjustment data to perform a gamma adjustment for the image data

• wherein when an image formation is performed by using:
• the same image data as the image data stored in a first storage section of the image forming apparatus;
• and a gamma value different from a gamma value applied to a prior image formation, the output section outputs new color adjustment data corresponding to the different gamma value.

A non-transitory computer-readable storage medium to store a program so as to make a computer of an image forming apparatus which forms an image based on image data input from an image processing apparatus, function as an adjustment section to perform a gamma adjustment for the image data based on color adjustment data for performing the gamma adjustment for the image data, and

• to store the image data and the color adjustment data in a first storage section of the image forming apparatus, and
• wherein when the same image data as the image data stored in the first storage section is used, and when new color adjustment data corresponding to a gamma value different from a gamma value applied to a prior image formation is input, the adjustment section performs the gamma adjustment for the image data stored in the first storage section based on the new color adjustment data.
