Abstract
Provided is an image control apparatus that includes a hardware processor. The hardware processor obtains read image data generated by reading an image formed on a sheet, sets read proof image data generated by reading a proof image formed on a sheet in a proof output as first correct image data, sets input image data as second correct image data, determines which one of the first correct image data and the second correct image data is used as correct image data in an image check for each page, and performs the image check by comparing the read image data obtained by the hardware processor with the first correct image data or the second correct image data determined as the correct image data by the hardware processor.
