Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a silver halide color photographic material suitable for proofing separation films for printing and a method for preparing a color proof using the same.

[Conventional technology]

When checking the quality of color printed matter, it is desirable to finally test the printed matter printed by this machine. However, this is not practical in terms of time, work, cost, etc. As a next-best measure, quality checks have been performed on proof sheets using a proofing machine. In response to the strict demands for delivery dates in recent years,
Color proofing systems that quickly and accurately perform inspections at the halftone printing stage after scanner disassembly have become important. For more information about the Color Blue 7 System (plate inspection system), check out the print magazine ``Color Proofing System Using Color Eaper'' written by Danki Nakamura! July issue, page 10-/, Toshihiro Shimizu, "Kanban 7 Nutem's way of thinking" Print magazine/Yr
Published in the February 2015 issue, pages 3-//.

A prepress film, which is a halftone image, is created from an original such as a reversal film, a color negative film, or a color paper. For color printing, there are usually three types of plate-making films: eye version, red version, black version, and black version. The entire process of checking characters, patterns, layouts, colors, gradations, etc. of these ≠ plate-making films is collectively called proofreading.

Checking things other than color tone and gradation during proofreading is called plate inspection. Materials used for plate inspection include 7 otopolymer diazo and electrophotographic methods, but these methods require a long time to work, have poor workability and require specialized operators, have high material costs, and require large and expensive equipment. There is a problem with hinoki. On the other hand, there is a method using a photographic material that is superior in terms of simplicity, rapid injection, and cost. For this method,

! is stated in the number etc. Methods using photographic M& source materials such as color paper, direct positive color eater, and their films are superior in terms of simplicity, speed, and cost, but there are problems with color tone and processing time, and improvements are desired. . In other words, when using photographic materials, in order to reproduce the tone from the separated halftone image close to that of the actual printed matter, it is necessary to reduce unnecessary coloring of the white background and reproduce fine halftone dots of 3 or less on the separated film (halftone reproducibility). ) was necessary, and this improvement was desired. Normally, photosensitive materials manufactured for the purpose of directly obtaining positive images contain yellow colloidal silver in order to eliminate the inherent sensitivity to unnecessary blue light of the emulsions in the green and red sensitive layers. There are layers. In order to achieve good color separation, it is necessary to remove more than 0.697 m2 of colloidal silver. However, colloidal silver in direct positive color light-sensitive materials has the disadvantage of worsening the p1 white background by softening the tone of the highlight part of the iD curve, which has a strong influence on photographic properties (L, which increases Dmin). Was. Therefore, as a color proof material,
A photographic material with good halftone dot reproducibility, good color reproduction, and a good white background is desired.

[Problem to be solved by the invention]

Therefore, the objects of the present invention are, firstly, to provide a photographic material capable of obtaining a next color proof with improved white background from a separated halftone image, and secondly, to provide a next color proof with excellent halftone dot reproducibility. The third object of the present invention is to provide a method for producing color proofs that can be obtained, and a third object is to provide a photographic material with improved processing time.

[Means to solve the problem]

As a result of intensive studies, the inventors of the present invention have found that the above-mentioned object can be achieved by the method shown below.

In a direct positive silver halide color photographic light-sensitive material containing at least one cyan color-forming coupler, maze/recolor coupler and yellow color-forming coupler on a support, the yellow colloidal silver base is o, ozt
7m2 or less, and the total photographic gradation after processing is 2.
．． Find out what you can achieve by making it greater than 0.

The transmission type black and white halftone dot image obtained by separating the component colors from the color original and converting it into a halftone dot image is closely adhered to a chromogenic color photographic light-sensitive material with a continuous tone density curve.
In a method for producing a color proof having a color image formed by halftone dots, which comprises separating the component colors with complementary colors and then performing color development processing, the above-mentioned direct positive material is used as the color photographic material using the color development method. We discovered that this can be achieved by using all of the light-sensitive materials, which are type-type silver chloride color photographic light-sensitive materials.
The point where it intersects j (A in Figure 1) and D=ko.

It is defined as the gradation of the photograph obtained when all points are connected to the point that changes from Q (B in Figure 1).

In other words, the reason for finding point A is that if the density is applied to the white background of the halftone image, the density of the proof image will apparently increase, which will confuse the judgment of halftone printing, so we found a point as close to the fog level as possible.

Point B was determined based on various experiments that show that the density of the highest Q-degree part of a halftone image is 922 or higher, as long as the area ratio of the halftone dots is approximately the same, and to Iruma's eyes, it looks the same. This is because only a change in the area ratio is transmitted through a change in the flk ratio.

The original material was subjected to full thickness imagewise exposure using an additive coloring method through a flat-tone transparent original with halftone dots Q to 100-. That is, the white light is passed through a Fuji Photo Film family 5c-to filter to give a red imagewise exposure, then the white light is passed through a Fuji Photo Film BPB-s3 filter to give a green imagewise exposure, and finally white light to Fuji Photo Film's BPB-μ! It was passed through a filter to give a blue imagewise exposure Xt. A Toshiba color rendering fluorescent lamp was used as the white light source.

Imagewise exposure was applied and the next sample was 7eye/checker-FCrjQ.
