Abstract

PURPOSE:To easily form a second image good in quality and superior in durability on a photographs print with high productivity by forming a second image by means of a printer on a surface of an emulsion side of the photograph print that is obtained by the developing treatment to a photographic paper. CONSTITUTION:Negative image information is inputted to an editing computer 3 from a photographic image information-inputting means 1 such as a scanner or the like and the image data is indicated on a CRT 3a. A position or a size of a second image is edited by using a character/illustration image information- inputting means 2 and an editing software 3b to be inputted to an information record medium 7. On the other hand, an image of a negative film is printed on a photographic paper by means of a printer 4 to be subjected to the development treatment by means of a photographic paper-developing machine 5 so that a developed roll 9 of the photographic paper is obtained. The second image of a character or an illustration is printed on a white portion of the photographic image of the roll 9 by means of a printer 6 and at that time the information record medium 7 controls the printer 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a second image (text, illustration, etc.) on a photographic print by using a printing machine, and more specifically, it is simple and durable and has excellent water resistance.
The present invention relates to an image forming method.

[0002]

2. Description of the Related Art With the diversification of photographic prints, photographic images such as postcards and characters and illustrations have been formed on the same photographic print. For the characters and illustrations, the mask material was made from computer typesetting or transmission type silver halide photographic light-sensitive material and printed on photographic paper. However, the burned-in characters and the image of the illustration are blurred, and it is complicated and costly to make the mask material.

Therefore, as a second image forming method, a thermal fusion transfer recording method is described in JP-A-4-34432. However, the heat-melt transfer recording method has a low recording speed and low productivity, and the durability and water resistance of the second image are poor. Therefore, there is a demand for a second image forming method for photographic prints that is simple and has excellent durability and water resistance.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a second image forming method which is simple and highly productive for photographic prints and which is excellent in high quality durability.

[0005]

The above object of the present invention is achieved by a method for forming an image on a photographic print by forming a second image on the emulsion side of the photographic print obtained by developing a photographic paper with a printing machine. To be done.

It is preferable that the ink used in the printing machine contains an ultraviolet curable resin and that the printing machine is of the stencil printing type because the effects of the present invention can be further exhibited.

The present invention will be described in more detail below.

Examples of the printing method used in the present invention include letterpress printing methods, lithographic printing methods, intaglio printing methods, stencil printing methods such as screen printing, especially when the number of copies such as postcards and guides is small, A stencil printing method is preferred for forming the second image on a photographic print having irregularities such as a silk surface.

For stencil printing, Japanese Patent Laid-Open No. 60-161150,
60-262684, 60-87094, 61-287745, 62-2
70376, JP-A-3-49980, 3-197078, 4-361043
No. etc. As a stencil printing method for obtaining a high-quality second image, a stencil stencil on which a thermoplastic resin film and a porous support are laminated is punched by heat from a thermal head or heat from laser exposure. It is preferable to prepare and print.

As a method for punching with a thermal head, there are disclosed in JP-A-60-87095, 61-40196, 61-116595 and 61-
295098, 62-170392, 62-181374, 63-30295

No. 2, No. 2-67133, No. 2-81691, No. 2-89694, No. 4-310
No. 740 and the like, and the perforation method by laser exposure is described in JP-A Nos. 63-35383 and 63-35387.

In order to obtain a second image having excellent durability and water resistance, printing containing an ultraviolet curable resin (eg, polyester acrylate, urethane acrylate, epoxy, polyol acrylate) and a photopolymerization initiator is performed. After printing with ink, it is preferable to cure with ultraviolet light, and it is described in JP-A Nos. 1-318073 and 2-41376.

Before or after forming the second image on the photographic print, a protective coat of a laminate, resin, wax, silicone oil or the like may be provided by a thermal transfer system or a coating system.

A typical process diagram of the system of the present invention (FIG. 1)
Will be described.

Reference numeral 8 is a developed negative film, and the negative image information is input to the editing computer 3 by the photographic image information input means 1 (for example, a scanner). This image data is displayed on the CRT 3a.

The position and size of the second image are edited using the character / illustration image information input means 2 and the editing software 3b,
Input to the information recording medium 7.

On the other hand, the negative film is printed on the printing paper by the printing printer 4 and developed by the printing paper developing machine 5,
The developed photographic paper roll 9 is obtained.

A second image of characters and illustrations is printed by the printing machine 6 on the white background of the photographic image 9. At this time, the information recording medium 7 controls the printing machine.

As described above, the photographic paper roll 10 having the final image in which the photographic image and the second image of the character / illustration are combined is obtained. Preferably, the ultraviolet ray irradiation device 11 cures the printing ink, and further performs cutting and laminating processes.

EXAMPLES The present invention will now be specifically described with reference to examples, but the present invention is not limited thereto. Unless otherwise specified, "part" means "part by weight".

Example 1 (Preparation of Photographic Print) A commercially available photographic printing paper (for example, Konica Color Type QA: made by Konica) was exposed with the first image and subjected to a predetermined developing treatment to obtain a photographic print.

(Preparation of Printing Ink) A mixture having the following composition was kneaded with a roll mill to obtain an ultraviolet curable stencil printing ink.

Ink composition Epoxy UV curing resin (UV-22C: Harima Kasei) 10 parts Polyester UV curing resin (SA-2006: Mitsubishi Yuka) 60 parts Bentonite powder (Thixogel VZ: Nissan Gardler catalyst) 8 parts Polyether silicone oil (manufactured by Shin-Etsu Chemical) 5 parts Acrylic resin powder (MP-3100, particle size 0.4 μm: manufactured by Soken Chemical) 2 parts Carbon black 10 parts Photopolymerization initiator (Irger Cure 651: Ciba Geigy) 5 parts A second image was formed on the photographic print using the above-mentioned ink using a rotary stencil printing machine (lithograph 007: ideal chemical), and then superposed by an ultraviolet lamp.

It did not fall off even if it was rubbed with a nail, and it did not deteriorate in 60 minutes of water immersion, and an excellent second image was obtained. FIG. 1 shows the created form.

Example 2 Instead of the ink of Example 1, the following composition was kneaded with a roll mill to obtain an emulsion ink. As a result of performing the same evaluation as in Example 1 using this ink, the water resistance was slightly inferior and a part of the ink dropped off after 60 minutes of immersion in water.
Min) did not change.

However, the material cost has increased.

Example 4 In Example 1, the stencil plate was replaced with a thermal head or He-N.
A second image of excellent print quality was obtained using the one perforated by the e-gas laser.
