Abstract

PURPOSE:To execute efficiently an excellent treatment without causing a misoperation by using a signal on a magnetic recording emulsion applied on a color print paper, in a laboratory treating process. CONSTITUTION:A color emulsion is applied on the surface of a barayta coating paper being a supporting body of a color print paper 20, and a magnetic recording emulsion 21 is applied in the shape of a wire on the rear side. The print paper 20 is capable of recording and reading an information to its applied magnetic recording body by providing an input/output mechanism of an information on a treating system in a laboratory, and records a laboratory information, a customer and film information, a print condition information, etc. When the developing treatment is executed in a state of a long size by a processor, a condition of a treating liquid, etc. are controlled by a lot number of the color print paper, and also, after the treatment, its treating condition, etc. are recorded as an information in the magnetic recording body. A cutter, a sorter and bagging are controlled by a computer provided separately, also scarcely require a person's help and processed rationally without causing an error by a magnetic recording information which a color print of one sheet each has.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a laboratory processing method carried out in a laboratory in the photographic industry.

Conventional technology Color negative film requested by the customer.

At the printer, printing is carried out on a long roll of color photographic paper, and after the printed color photographic paper is developed, it is sent to the Imperial Palace and sorted. The sorted color photographic paper is returned to the customer together with the color negative film.

Figure 1 shows a standard laboratory processing process that can be applied to a laboratory. If the requested color negative film is undeveloped, the film will be developed. The developer film connected in a roll is used for the next printing process.

On a long roll of color photographic paper, an image on a negative film is printed by a printer, and then the photographic paper is developed by a developing machine (processor). After the development process, the roll of color photographic paper is inspected by an inspector, and a mark is placed on the part of the color print that is deemed unsuitable for shipment to the customer. The negative film corresponding to the marked color print is reprinted under the corrected printing conditions. After checking and editing with an inspector, the roll of color photographic paper is cut into individual color prints with a cutter.
In the next sorter, the negative films and color prints corresponding to the customer are combined and loaded, and the charges are calculated before being shipped.

Although the laboratory processing methods described above are being improved in the direction of labor saving and rationalization, they still require a large amount of manpower and skill.

In the case of additional print orders called reprints, rationalization is more difficult than simultaneous prints, and more manpower is required.

From the standpoint of streamlining the laboratory, it is desirable that print information other than images be stored in each color print. Conventionally, print information has been inserted into the screen frame portion or the back side of a color print by burning or printing. Generally speaking, printers are based on the integral neutral method and print automatically by automatically controlling the exposure time based on the image density of the negative film. However, as is well known, in special scenes such as snowy scenes or indoors under a tungsten light source, the density may vary. Measuring alone will not produce good prints with automatic printers. Generally, printing is performed using the automatic printing conditions as a standard, with corrections added thereto. This correction condition has been recorded on color prints. When reprinting a color print that was previously checked as defective by the inspector, it is extremely easy to correct it if the previous printing conditions are known. Also, when receiving an order for reprinting, if the previous color print is shown, the correction conditions can be read from it and printed under the same conditions to obtain a reprinted print with the same image quality. If print information other than this is included in the color print, such as information about which film and how many frames/eyes of the negative are printed, then the color print will be loaded together with the corresponding negative film in the previous sorter. It is extremely convenient when putting it in. Also, information such as the year, month, and day of the process and the number of the printer on which the printing was performed are also effective. However, there is a limit to the amount of printed information that can be recorded depending on the conventional information recording method of printing dots on a narrow screen frame or typing on the back side of photographic paper.

Purpose of the Invention The present invention improves the conventional laboratory processing method by recording and reading a required amount of signals in addition to images relatively easily on color photographic paper, and provides a more rational and favorable method. The purpose is to provide a laboratory processing method in which the processing is carried out.

Structure of the Invention The present invention involves printing on color photographic paper from a color negative film, developing the printed color photographic paper, and then cutting and sorting it into specified dimensions in a laboratory process. The present invention provides a laboratory processing method characterized in that a color photographic paper having a part of the support coated with a magnetic recording emulsion for recording and reading is used, and the signal is used for laboratory processing.

Embodiment Figure 2 (a) shows an embodiment of the color photographic paper used in the present invention, in which a color emulsion is applied to the front surface of baryta paper as a support, and magnetic stripes are applied to the back surface. This is color photographic paper coated with recording emulsion 21.

In the illustrated example, a magnetic recording emulsion 21 is coated in a stripe pattern parallel to the winding direction of a long color photographic paper, with the center position in the width direction off. The reason for removing the center position of the magnetic recording material in the width direction is to clarify the direction of the leading edge of the magnetic recording material on the back side when the cutter cuts a long color photographic paper into a single color print. be.

In this embodiment, only one magnetic recording body is used, but depending on the amount of information to be recorded, it is possible to provide a plurality of magnetic recording bodies or to coat the entire back surface. However, this magnetic recording emulsion has the risk of curling the support depending on the amount of solvent and drying conditions. In particular, as the width of the magnetic recording medium becomes wider, the degree of curling increases (increasingly).Also, when the magnetic recording medium is widened, curling becomes thicker.
If the winding is thick, the side coated with the magnetic recording material will be high, which will cause a problem, so the magnetic recording emulsion 22 is placed in two stripes so that it is balanced left and right with respect to the center position in the winding direction.
A and 22b are applied, as shown in FIG. 2(b).

One of the two magnetic recording bodies 22a is used for recording and reading signals, and the other magnetic recording body 22b is used only for reading, which will be explained later, and contains black and white information that serves as a length reference. .

With the color photographic paper described above, by adding an information input/output mechanism to the processing system in the laboratory, it is possible to record and read information on the coated magnetic recording medium as shown in Figure 3. can.

(1) The position corresponding to the color image printed on the long color photographic paper by the printer,
That is, on the back side of the printed color image, (a) laboratory information such as the lot number of the photographic paper, printer number, and processing liquid conditions in the processor for the next process, (b) film type, film roll number, film frame number, etc. customer/film information, e-syslope control, g
Light correction or printing condition information such as BGRD information is recorded.

(2) When a long sheet of paper is developed by a processor, the conditions of the processing liquid are different from those of color photographic paper.

After processing, the processing conditions and the like are recorded on the magnetic recording medium as information. It is possible to record the printing conditions in the process, or to record the printing conditions etc. in advance in the printer section.

(3) A check is made by the inspector to determine which prints are defective and need to be reprinted and which are unnecessary to be discarded. The inspector reads information from the magnetic recording medium of the defective print, compares the read information with the defective print, determines the amount of correction under the printing conditions, and determines the amount of correction for the corresponding negative film based on the read film number and film frame number. This will be reprinted using a printer. □The printer to which the reprint is performed may be the same as or different from the printer described above. Furthermore, for defective prints φ and unnecessary prints, it is possible to record on the corresponding magnetic recording medium that the prints are defective and unnecessary.

(4) For long color photographic paper depending on the cutter, CI,
At C2..., the force is applied (Fig. 2), resulting in a large number of color prints. In this case, the above-mentioned defective print
Unnecessary prints can also be eliminated by identifying defects and unnecessary records on the magnetic recording medium. Conventional cutters have optically detected the color screen frame and cut for each frame, but if the printer records the force and marking marks on a magnetic recording medium when printing, the cutter can perform magnetic recording. You can perform force and to by the force and ting mark above.

(5) The sorter is connected to the above-mentioned power supply and output, and reads out the film number, film frame number, and number on the magnetic recording medium, eliminates defective and unnecessary prints, and sorts the prints into groups for the same customer. , and are ejected in synchronization with the corresponding negative film.

(6) For loading, the number of prints, print price, etc. are printed on the bag, and the negative films and color prints that were removed at the same time are stored in this bag. If there is a defective print, a warning to that effect is given at the time of loading, and a request is made to add/insert a reprint print.

(7) Cutter/sorter e-loading is controlled by a separately installed computer, and is processed rationally without errors and with almost no human effort, using the magnetically recorded information contained in each color print. Ru.

The laboratory processing method of the present invention for simultaneous printing of J-135 film has been described above. In addition, in the case of reprinting, by transferring the recording of the color print to be reprinted on the magnetic recording medium as it is and forwarding it to the laboratory along with the negative film, the reprinted print will have exactly the same image quality as the previous color print or print. can be obtained.

Furthermore, in the above embodiment, information was written on the magnetic recording material on the color photographic paper after the printer in the laboratory processing process, but as shown in FIG. By writing the , , and ri signals on the magnetic recording medium 22b, the printer can feed paper using this clock signal.

Note that the present invention is not limited to laboratory processing of 135 film. A laboratory processing method that is systemically combined with a disc film is also possible, and the negative information and user information recorded on the negative are transferred to a color print magnetic recording medium, thereby performing the same processing as in the above embodiment.

Effects of the Invention As explained in the above embodiments, the present invention has made laboratory processing, which conventionally required a lot of manpower and skill, efficient, error-free (and excellent processing). Note that the present invention is characterized in that signals on a magnetic recording emulsion coated on color photographic paper are used in a laboratory processing process, and there are other methods of use in laboratory processing other than those described above, but none of them are applicable. are also included in the present invention.
