Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention describes the lot number, photographic characteristics, etc. of the photographic emulsion used in the manufacturing process. The emulsion information consisting of is related to a photographic light-sensitive material recorded on itself.

0002

[Conventional technology]

It is no longer necessary to record the lot number of the photographic emulsion on packaging materials for photographic materials. is being carried out. For example, with 35mm roll film for photography, the cartridge Emulsion information is recorded with a barcode on the surface.

0003

[Problem that the idea aims to solve]

Photographic materials are photographic emulsions on a substrate (base) such as film or paper. This emulsion is coated and dried, and since this emulsion contains gelatin as a component, , slight differences occur depending on the preparation lot. The difference is in photosensitivity and color tone. It may be the amount of physical deformation (for example, expansion or contraction due to humidity). this This difference can cause problems when performing various processing such as photographing, developing, printing, etc. It may happen.

0004 Therefore, in the past, emulsion information was recorded on the packaging material of the photographic material, and the necessary information was The user was devised to make use of this information. For example, as mentioned above For 35mm roll film, emulsion information is recorded on the cartridge as a barcode. The camera can read this information and use it when shooting. It can also be used in development processing if desired.

[0005] However, the emulsion information is not recorded on the photographic material itself, but on the packaging material. In the conventional method, when the photographic material and packaging material are separated, the emulsion information is information is not available. For example, in the currently popular DPE service, Before processing, the film is removed from the cartridge or magazine. Furthermore, ordered films are randomly spliced together and made into a series. Since the emulsion information is processed while being transported, emulsion information cannot be used. Pudding Similarly, it cannot be used at the stage of creating a list.

[0006] Therefore, the present invention aims to improve each process from photography to printing, which involves photographic materials. The aim is to identify improved photographic materials that can utilize emulsion information. The target is

[0007]

[Means to solve the problem]

In this invention, the lot number of the photographic emulsion used in the manufacturing process is written on the photographic material itself. It is characterized by recording emulsion information such as.

[0008]

【Example】

The present invention will now be described in more detail according to embodiments shown in the accompanying drawings.

[0009] Figure 1 shows an example in which the present invention is applied to a 35mm roll film 1 for photography. Then, film 1 is stored in cartridge 2 in a light-shielded state, leaving a little leader part 3 at the tip. The emulsion information record 4 is stored in the leader section 3 or the beginning of the image forming section. placed in parts.

0010 The emulsion information record 4 can be recorded using barcodes, punch holes, cutouts, magnetism, etc. This can be done directly on the film 1 or by using adhesive paper. Furthermore, this At the same time, emulsion information is also recorded on the outer circumferential surface of Patrone 2 using barcodes as before. This does not preclude the placement of Record 4.

[0011] In the embodiment shown in Figure 1, the film returned from the DPE service is of a fixed length. The emulsion information may be changed depending on the image frame when reordering the print. There will be cases where record 4 is not included. Therefore, to resolve such cases In order to do this, as shown in FIG. Emulsion information is placed between perforations 6 or along perforations 6. The information records 4 are arranged continuously or intermittently at regular intervals.

0012 A transparent magnetic layer is formed on the side opposite to the emulsion side of film 1, that is, on the backup layer side. In this type of photographic material, the emulsion information recording 4 is also magnetically recorded in the image forming section 5. It can be provided by Non-transparent in a certain width along perforation 6 Emulsion information and other information can also be recorded by providing a bright magnetic layer.

[0013] The concept of the embodiment explained according to FIG. 2 is that the photographic material is It is also applied to cut sheet forms such as medical films.

[0014] Like the so-called one-ten film, both the leading and trailing ends of film 1 are inside the spool. In the embodiment described above, the emulsion information record 4 is placed in an exposed portion in an unused state. .

[0015] The emulsion information added to the photographic material itself is stored as soon as the photographic material is loaded into the equipment. This information is read by the information reading means provided on the device side. Each process is controlled based on. For example, emulsions in photographic materials are numbered. This emulsion number is used to prepare the photographic material and associate the manufacturing information. can be done. Also, do each emulsion have slightly different sensitivity characteristics and physical characteristics? By utilizing this information, appropriate processing control can be performed. For example, when shooting When processing, it is necessary to correct the exposure control based on the emulsion information, and to Control of contact time with processing liquid, control of processing temperature, control of replenishment amount of processing liquid, and processing Controls the stirring of the agent, etc. For drying, the drying temperature and amount of hot air are controlled, and the In the processing, the standard transmission density may change depending on the emulsion, so please take this into consideration. Corrections must be made at the printing stage, and emulsion information must be adjusted to control exposure and color filters. Use it to your advantage.

[0016]

[Effect of the idea] According to this invention, emulsion information is utilized at each process stage from photography to reprinting. This enables high-performance processing and solves the above-mentioned problems.
