摘要： A print monitoring apparatus for monitoring a print transported out of a printing unit comprises a defect position discrimination unit for discriminating a position of a defect on a print web of the print fed from the printing unit, a defect memory unit for storing defect position information given from the defect position discrimination unit and record information containing defect occurrence time, a number of successive occurrence pages, a roll paper name and a number of used pages, and a display unit for displaying the information stored in the defect memory unit. In another aspect, a print monitoring apparatus for monitoring a print transported out of a printing unit comprises a print defect detection unit for detecting defect on a print web of the print fed from the printing unit, the defect detection unit including a monitoring sensor for dividing a print surface of the print web into a plurality of pixels and converting information of pixels into electric signals representing density information of the respective pixels, a central processing unit for processing information data regarding the density information of the respective pixels from the print defect detection unit, and a defect content discrimination unit for discriminating defect content in accordance with information data from the central processing unit and preliminarily set reference for the discrimination.
