Abstract

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.

Claims

1. A photographic printing apparatus comprising:

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 means for effecting exposure of image data at the exposing unit on the material piece transported by the transporting section; and

a calibration printing means for effecting exposure of predetermined calibration data at the exposing unit on the material piece transported by the transporting section;

wherein said calibration printing means is operable to effect an all calibration mode operation in which the plurality of 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.

2. The photographic printing apparatus according to claim 1, further comprising:

a processing unit for effecting the exposure of the image data by the order executing means and effecting also the exposure of the calibration data by the calibration printing means; and

a display unit for displaying processing information processed by the processing unit;

wherein when an operator selects a calibration operation, said processing unit causes said display unit to display an individual calibration mode button for effecting an individual calibration mode operation for each of the plural magazines and an all calibration mode button for effecting said all calibration mode operation, and after the exposure of the calibration information, said processing unit causes said display unit to display, for each magazine, a calibration screen for allowing adjustment of a center of the exposure position relative to the photosensitive material from that magazine.

3. The photographic printing apparatus according to claim 1, wherein said all calibration mode operation processes character information for identifying a magazine or a transporting lane for the photosensitive material, in addition to the calibration information.

4. The photographic printing apparatus according to claim 1, wherein said calibration data further includes data for identifying a size of the photosensitive material along a sub scanning direction, in addition to the data for indicating the exposure center position.
