ABSTRACT:
A paper sheet P is fed to a transport mechanism, which conveys the sheet to a printer section, which prints a pattern on the sheet P. The image data on the printed sheet is supplied to an image input section, and compared with standard data at a print inspect section. The compared image data is sent to data display sections as the occasion demands and judged to be acceptable or unacceptable at judgment input sections. The judgment results are sent to a sort mechanism, which discards unacceptable printed matter P. This printing apparatus allows the judge to make a final judgment on printed matter containing minute defects or faint defects that the inspecting process cannot judge, and collects the judgment results, thereby being capable of printing while sorting only acceptable products accurately without lengthening the processing time.
