Abstract: A printed image inspection apparatus comprises an image reading section that irradiates a printed image being inspected with two types of light having different dominant wavelengths and reads images from the reflections of the two types of light, a judgment section that compares the images read by the image reading section with reference images stored in advance and judges the agreement between both, and an operation control section that control the operation of the image reading section and the judgment section. The image reading section comprises a first light source outputting blue light having a low reflectance with respect to yellow, magenta and black inks, and a second light source outputting yellow light having a low reflectance with respect to cyan, magenta and black inks.
