Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color photographic light-sensitive material and a method for producing a color proof using the same. More specifically, the present invention relates to a color proof used for plate inspection / adjustment in a color plate making / printing process. And a method for producing a color proof using the same.

[0002]

2. Description of the Related Art Conventionally, in a color plate making / printing process, a method for obtaining a color proof from a plurality of black and white halftone images obtained by color separation and halftone image conversion is to use a photopolymer or a diazo compound. An overlay method for forming a color image and a surprint method are known.

[0003] The overlay method is very simple, has a low production cost, and has the advantage that it can be used for calibration only by stacking four color (subtractive primary colors and black) film sheets. The drawback is that gloss is produced by the overlapping, which results in a texture different from that of the printed matter.

In the surprint method, a colored image is superposed on one support, and a method of obtaining a colored image by toner development utilizing the adhesiveness of a photopolymerizable material is disclosed in US Pat. No. 3,582,327. Nos. 3,607,264 and 3,620,726.

Further, a color proof is formed by transferring a photosensitive coloring sheet to a support, forming an image by exposure and development, laminating another coloring sheet thereon, and repeating the same process. The method of creating is 47
-27441 and JP-A-56-501217.

Further, a method is known in which a photosensitive colored sheet is used and each colored image obtained by exposing and developing the corresponding color separation film is transferred and formed on one support.
-Known as No. 97140. Since there is an advantage that a coloring material similar to the printing ink can be used as a toner for forming these images and a coloring agent for the coloring sheet, the color tone of the obtained color proof is close to that of a printed matter.

However, these methods have the drawbacks that images must be superposed or transferred in the process of producing a color proof, which requires a long operation time and a high manufacturing cost.

As a solution to these drawbacks, a method for producing a color proof using a silver salt color photographic light-sensitive material having a white support is disclosed in JP-A-56-113139 and JP-A-5-113139.
6-104335, 62-280746, 62-280747, 62-280
No. 748, No. 62-280749, No. 62-280750, No. 62-280849, etc.

In this method, a plurality of color-separated black and white halftone images converted from a color original into color-separated halftone images are sequentially printed on one sheet of color paper by a method such as close-contact printing to perform color development. The color image formed by the dye formed from the coupler imagewise by color development and color development is used as a proofing image.

Among the silver halide color photographic light-sensitive materials that can be used for such color proof, particularly in Japan and Europe, the transmission type black and white halftone image used in the process of forming a color image is often a positive type, As a silver halide color photographic light-sensitive material for proof, a positive-positive type light-sensitive material is often used.

In recent years, practical application of high-definition plate making / printing has been strongly desired from the viewpoint of improving the image quality of printed matter. However, the reproducibility condition of the fine minimum point is strict, and the reproducibility thereof is also desired to be improved. However, the reality is that it has not yet become popular. Further, in terms of obtaining a color proof for high-definition printing as well, there is a point that it must be improved in the same manner as in plate making and printing.

In order to obtain a proof image using a conventional positive-positive type silver halide color photographic light-sensitive material for color proof, when exposure is carried out for a yellow plate, a magenta plate and a cyan plate, yellow is used. , The black and white halftone dot image plates for magenta and cyan plates must be overlapped with the black and white halftone dot image plates for exposure, so when the proof for high-definition printing is obtained, the registration mark is fine. There is a problem that the reproducibility of the neutrality is deteriorated due to the misalignment, and either the small dots of black or the small dots of a single color are not reproduced on the plate.

The frequency modulation (FM) screen method has the same problem as high definition printing. For the FM screen method, for example, “Printing Magazine” 1994 (Vol. 77)
6, p49, etc., the frequency (F) is used to describe the nature of waves and represents the number of waves (frequency). Also the amplitude (A)
Represents the height of the wave. Applying the concept of frequency and amplitude to screening, at screen frequency (F) it can be understood as the number of halftone dots per cm and at the same time the width of the halftone dot. On the other hand, the amplitude (A) describes how large a point is in terms of area. As is well known in conventional screening, points of different sizes are generated, but they are all equidistant. This is amplitude modulation (A
M) Can be called screening. In frequency modulation (FM) screening the spots are always the same size but at different distances.

In JP-A-61-233732, JP-A-4-1632 and the like, in addition to the yellow color forming layer, the magenta color forming layer and the cyan color forming layer, a fourth spectral sensitivity wavelength difference is used for all layers. A technique of providing a black plate layer is disclosed. Although this technique solves the above-mentioned problem to some extent, its effect is insufficient, and when the amount of light of a light source that is sensitive to a specific emulsion layer during four exposures is increased, It was unexpectedly found that the problem that the concentration of other silver halide emulsion layers is lowered (overexposure property) can occur even without high-definition color proofing or FM screening. In addition, JP-A-61-233732 and JP-A-4-1632 do not mention the application to high-definition printing, which is high-quality printing capable of obtaining an image similar to a printed matter, or printing by FM screening. In addition, there is no description about the defect due to its application to high-quality printing.

Alternatively, a method of controlling the pH, dissolving the dye once, and then changing the pH to obtain fine crystals can be applied. The fine particles of the dye thus obtained exhibit the effect of the present invention by being uniformly dispersed in the binder.
