Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a finished printing cutter used when cutting a continuous printing paper on which an image of a negative film has been subjected to a printing and developing process for each image pattern.

[Conventional technology]

A continuous printing paper on which an image of a negative film is printed by a printing device is developed by a developing device and then cut into image parts to be commercialized.

In the printing process in this printing apparatus, the printing exposure amount on the printing paper is optimized to obtain the best print image. That is, a notch puncher is used to punch a semi-circular notch at the side edge of the negative film and at a position corresponding to the image pattern, and according to the average transmission density (LATD) obtained by measuring the image with a printing device. Information of the exposure correction amount with respect to the exposure amount is stored in a paper tape as a storage medium. Further, this paper tape is loaded into the printing apparatus, and the presence of notches is detected by a photoelectric switch or the like while conveying the negative film in synchronization with the paper tape, and when the presence of the notches is detected, the conveyance is stopped and the notches detected. Position the image pattern corresponding to
The exposure amount correction information stored in the paper tape is read and printed based on this. Further, the printing paper after printing is sent to a finished printing inspection apparatus after being subjected to development processing, and is visually cut by an operator to judge whether the printed image is good or bad, and then cut into each image pattern.

[Problems to be solved by the invention]

By the way, the optimum exposure amount of the negative film is LA as described above.
Since the exposure correction amount with respect to the exposure amount corresponding to TD is visually determined by the operator, it is easy to determine an appropriate exposure correction amount in the case of a negative film having a density area or a negative film having a color area, for example. In some cases, the finished print image may be determined to be defective. Also,
Printing may fail due to mechanical failure of the shutter. In these cases, it is necessary to reprint the image.

However, it has been extremely difficult to retrieve the pattern corresponding to the defective print image from the photographic paper cut for each image pattern from the similar image patterns of the negative film.

In addition, even when the customer reorders such as reprinting, it is difficult to associate the printed image with the negative image of the negative film, and it is complicated to specify the pattern.

In consideration of the above facts, the present invention has an object to obtain a finished print cutter capable of easily performing inspection collation between the photographic paper cut for each print image and the image pattern of the corresponding negative film. .

[Means for solving problems]

The finished printing cutter according to the present invention is a finished printing cutter for cutting the continuous printing paper after printing and development from a negative film for each image frame, and the continuous printing paper after the printing and development is performed. A conveyance device for conveying to the cutting position, and exposure amount correction information for correcting the exposure amount at the time of printing the negative film together with the frame number attached to each image frame in order to identify the image frame of the negative film are read in advance. A reading device that reads this frame number from the stored storage medium,
A printing device for printing the read frame number on the continuous printing paper conveyed by the conveying device.

[Action]

In the finished printing cutter having the above structure, the printing paper is conveyed to the cutting position by the conveying device. At this time, the image frame number of the negative film corresponding to the print image at the cutting position is read from the storage medium by the reading device. Further, the read pattern number is printed by the printing device on the photographic paper on which the image is printed. Therefore, when searching and collating the printed image of the photographic paper after cutting and the image pattern of the corresponding negative film, it is sufficient to take the correspondence with the negative film by the pattern number printed on the photographic paper. Search collation is possible.
