Gradation refers to the dark to light continuum of shades of color. The more shades in the gradations of color that are printed, the more natural printouts seem. When the gradation or density of the copies is significantly different from that of the original document, perform the gradation adjustment so that the copy results more closely match the original document. Note that you cannot perform this adjustment while the machine is performing some functions, including scanning and printing.
