Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION The present invention develops a plurality of films and prints each image on the film on photographic paper. The method relates to a method in which the film and the printed photographic paper are easily identified in order to identify whether the film is printed or not.

[Conventional technology]

When a conventional film is developed in a lab and its film screen is printed on photographic paper, a tack label with a number corresponding to the receipt number from the customer is attached to each film terminal, and a tack label with the same number is attached. Attachment to a paper bag to be returned to the customer has been devised so that the customer, the film and the printed product stored therein match, and are distinguished from others. At the large lab, after the film development, the film and prints were returned to the customer in exchange for the bag and film after going through the notcher process, printing process, checking process, and cutting process for each printed image. This is substantially the same for both simultaneous printing and reprinting printing.

[Problems to be solved by the invention]

However, on the photographic paper on which each image is printed, the identification numbers or symbols attached to each one are not imprinted or printed as identification codes, so that errors in the process have been made. Tends to occur. On the other hand, it has been proposed that the frame number of the film be imprinted on the back of each print, which has already been implemented on disc film and is very convenient for customers when ordering reprints. However, the print does not have a number or symbol identifying it corresponding to the aforementioned film. Therefore, when a customer, for example, submits two or more films for simultaneous printing, sees it, selects a particular one, and reorders, each print is mixed up in the whole. Even though the frame number is printed on each print, the identification number or symbol of the film corresponding to it is not written as an identification code, so it is not possible to select only by looking at the frame number on the back of the print, and eventually the film number While comparing the film image frame with the print image, the user goes back to the troublesome identification method.

An object of the present invention is to provide a photographic printing method which can easily identify a film and a printed photographic paper by solving such an absurdity, and which is convenient and rational for both customers and laboratories.

[Means for solving the problem]

An object of the present invention is to provide a film identification code from a film to which a film identification code for each manufacturer for identifying a film for each film and a frame number code for identifying each image frame in one film are assigned. A step of reading the frame number code and a step of creating a print, wherein the film obtained by the reading is identified by a print created based on an image frame of the film. This is achieved by a photographic printing method characterized by recording film identification information for each manufacturer and a frame number for identifying the image frame.

〔Example〕

One embodiment of the method of the present invention will be described with reference to FIGS. Hereinafter, the identification code is treated as a generic term including the identification number and the identification symbol.

After receiving the development for simultaneous printing in the development lab, an identification number 122 was determined for each film, and then a tack label 120 on which the number 122 and a bar code 121 were printed as the corresponding identification code was attached to each film. Tip terminal 110
Paste in the fixed position. The leading end portion 110 is formed by cutting the tongue end portion unique to the film before development, and the cut end and the perforation are joined to the trailing end portion 120A of a different number film and joined with an adhesive tape 121A and rolled. And sent to the developing device. The developed film is the first
As shown in the figure, each image frame 14, the DX code 20, the frame number 20 'including the main number and the sub number, and the frame number codes 26 and 28 corresponding to the frame number 20' are attached. Then, the film in this state is sent to the puncher 100.

In the puncher 100, the barcode 121 for the identification symbol of the tack label 120 is read by the barcode reader 151, and the signal is sent to the control device 52. Then, a signal from the control device is sent to the punching machine 60 and punched on the paper tape 58. This information is held as the same signal until the identification symbol barcode 121 of the tack label 120 at the leading end of the next film is detected. The image density information and the like are read by a reader 40, and a DX code reader 48 and a frame number code reader 50 provided on both sides of the transport film at substantially the same position as the image density information signal in the film advancing direction. The information signal read by the controller enters the controller 52, and is punched by the punching machine 60 on the paper tape 58 of the recording medium. Further, the image density information and the identification number for each film can be separately input by the ten keys 56.

The information recorded on the paper tape in this manner is sent to the printer 150. Then, the developed original film 10 is conveyed through the printer 150 in synchronization with the paper tape for printing on the printing paper 66, and each image frame 14 of the original film 10 is conveyed corresponding to the film 10 and the paper tape 58. Is printed on the photographic paper.

In this printer 150, the film 10 is fed in the direction of arrow C, and the image frame 14 stops on the optical axis 72 formed by the light source 68 and the light diffusion tube 70 in the course of this feeding. An optical system 74 and a shutter 76 are provided below the image frame 14 so that an image can be printed on photographic paper 66.

The information of the paper tape 58 sent in the direction of arrow D is read head.
It is read at 78 and a setting signal is sent to the control device 80. Further, the barcode readers 82 and 88 correspond to the film 10 on the optical axis 72. The barcode readers 82 and 88 read the frame number barcodes 26 and 28 and the DX barcode 20 and send a read signal to the control device 80. I have. Further, the bar code 121 for the identification symbol for each film is also read by the bar code reader 152, and the signal thereof is transmitted to the control device 8.
Sent to 0. Further, a dot printer 84 is provided corresponding to the back surface of the printing paper 66, and the frame number read by the barcodes 26, 28, 121 and the identification number as an identification code for each film are printed on the image frame by a signal from the control device 80. Is printed on the back surface of the photographic paper 66 in correspondence with.

As a recording medium, it is possible to use an IC card or a magnetic tape system in addition to a paper tape.

In this way, the frame number is clearly printed on the back surface of the printing paper, and the identification number as an identification code for each film is also printed near the frame number on the back surface of the printing paper. A tack label printed with the same number as the identification number is attached to the leading terminal of the film, so that the collation between the print and the film can be easily recognized.

This identification number can be assigned a serial number for each maker for each film. There are a method of inserting an identification number for each patrone, a method of burning the identification number as a latent image on a film, and the like.

However, as an immediate use method, not only the order number used for the work as a development lab is stamped on the film negative cover return bag etc. but also recorded on the back of each finished print from the viewpoint of streamlining the lab and the benefit of customers Worth watching.

The means for back printing the identification number can be performed as shown in FIGS. 1 and 2 described above. The detection position of the identification code bar code as the identification code is located on the upstream side of the puncher 100. It may be on the downstream side of.

In addition, the printing of the identification number on the back of the finished print is performed in an automated state as described above.In addition, the identification number such as a bar code is collated with the order number under the organized lab management state. Alternatively, the number may be manually stamped on the back of the finished print, or the number may be written by hand.

The identification code may be attached to the film at the DP window,
The code may be once written on a recording material such as a DP bag and read by the lab, and the code may be attached to the film.

The identification code may be directly read by OCR or the like.

〔The invention's effect〕

When simultaneous printing or reprinting printing from the same customer is ordered in large quantities by a plurality of films according to the present invention,
Confusion in the lab process is avoided, and customer reorders for prints are immediately and reliably and easily made without errors, creating invaluable utility.
