Abstract:
1. An image inspection apparatus which inspects a performance level of a result of overprinting in an overprinted paper obtained after an overprinted element is printed on a pre-printed paper having a pre-printed element printed thereon in advance, said image inspection apparatus comprising: a pre-printed element reduction section that performs an arithmetic process on image data of said pre-printed paper, which is obtained in advance, and image data of said overprinted paper, and generates an inspection object image in which the pre-printed element included in the image data of said overprinted paper is reduced but is not completely removed; and a comparative inspection section that receives image data of said inspection object image outputted from said pre-printed element reduction section, and compares the image data of said inspection object image with the image data of said overprinted element, to thereby inspect the performance level of a result of overprinting, wherein said pre-printed element reduction section includes an adjustment means for reducing a difference between brightness of said pre-printed element and brightness of the paper serving as a base, and generates image data of said pre-printed paper in which said pre-printed element is reduced without said pre-printed element being completely deleted, by increasing brightness of the image data of said pre-printed paper.
