Abstract
An image inspection apparatus includes a pre-printed element reduction section that reduces influence of a pre-printed element on inspection and generates an inspection object image, and a comparative inspection section that compares the inspection object image with the additionally-recorded data, to inspect a performance level of a result of overprinting. Captured image data of the pre-printed paper image and the overprinted image is given to the pre-printed element reduction section. By using the captured image data of the pre-printed paper image, the pre-printed element reduction section reduces the pre-printed element included in the captured image data of the overprinted image and newly prepares the inspection object image.
