US Patent 7372537 Print processing apparatus capable of calibration printing

A photographic printing apparatus includes a transporting section for cutting photosensitive material drawn from one of a plurality of magazines each accommodating therein an elongated photosensitive material into a print size piece by a cutter unit and then feeding this material piece into an exposing unit, an order executing unit for effecting exposure of image data at the exposing unit on the material piece transported by the transporting section and a calibration printing unit for effecting exposure of predetermined calibration data at the exposing unit on the material piece transported by the transporting section. The calibration printing unit is operable to effect an all calibration mode operation in which the plural magazines are designated one after another, the photosensitive materials from the respective designated magazines are cut into the print size pieces and the exposing operations of the predetermined calibration data for indicating an exposure center position relative to the width of the photosensitive material are effected on the print size pieces one after another continuously.
