Abstract
In a printed product color misregister amount detection method, a reference register mark including a first color area portion with a predetermined width and a blank portion in contact with the first color area portion is printed in a reference color on a printed product to be printed by a multi-color printing press. A positional shift detection register mark including a second color area portion with a width smaller than that of the first color area portion of the reference register mark is printed in a color other than the reference color to have as a target position a position where the width of the second color area portion falls within the width of the first color area portion of the reference register mark. Density information representing a density of a color component which is of the same color as that of the positional shift detection register mark within a target range including the first color area portion and the blank portion in contact with the first color area portion of the reference register mark where the positional shift detection register mark has been printed is measured. A positional shift amount between the reference color and the color other than the reference color as a color misregister amount is obtained on the basis of the measured density information.
