Patent ID: 8867094

Claim:
A printing system comprising: a first image creation section that creates first image data by performing first image processing on original image data, the first image processing including correction of a characteristic that is unique to an image forming section and first processing that is different from the correction of a characteristic that is unique to the image forming section; the image forming section that forms an image on a recording medium using the first image data input to the image forming section; a second image creation section that creates second image data by performing second image processing on the original image data, the second image processing including the first processing, but not including the correction of a characteristic that is unique to the image forming section; an image reading section that reads the image having been formed on the recording medium by the image forming section to obtain read image data; and a detection section that detects a defect in the image having been formed on the recording medium by the image forming section, by comparing the read image data resulting from the reading performed by the image reading section or comparison image data obtained by performing processing on the read image data with the second image data on a pixel-by-pixel basis, the read image data and the second image data being obtained from the same original image data.
