Patent ID: 8917903

Claim:
An image inspection apparatus for inspecting images formed on a recording medium having a first side and a second side opposite the first side, comprising: a penetrated-image information obtaining unit to obtain penetrated-image information corresponding to an image penetration from the first side to the second side when an image is formed on the first side; an inspection information storage to store information used for an image penetration inspection, the information including an upper permissible limit of image penetration from the first side to the second side caused by the image formed on the first side; a pre-print image penetration inspection unit, using a processing device, configured to: obtain an image penetration level from the first side to the second side based on the penetrated-image information obtained by the penetrated-image information obtaining unit; compare the obtained image penetration level and the upper permissible limit of image penetration stored in the inspection information storage; and inspect an image penetration from the first side to the second side when the image is formed on the first side of the recording medium; a pre-print image penetration prediction unit to predict, before an image is formed on the second side, an image penetration level from the second side to the first side caused by the image to be formed on the second side, based on the penetrated-image information obtained by the penetrated-image information obtaining unit and data of the image to be formed on the second side; and a post-print image inspection unit, using the processing device, to inspect quality of the image already formed on the first side and the image formed on the second side after forming the image on the second side, based on the prediction result computed by the pre-print image penetration prediction unit.
