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 is used for plate inspection / adjustment in color plate making / printing process. The present invention relates to a silver halide color photographic light-sensitive material suitable for producing a color proof to be used, and a method for producing a color proof using the same.

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 a 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 color 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. Frequency modulation (FM)
The screen method has the same problems as high-definition printing. For the FM screen method, for example, "Printing magazine" 1
994 (Vol.77) 6, p49, etc., frequency (F) is used to describe the nature of waves, and the number of waves (frequency)
Represents 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 dots per cm and at the same time the width of the screen. 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 can be referred to as amplitude modulation (AM) screening. In frequency modulation (FM) screening the spots are always the same size but at different distances. When a yellow plate, a magenta plate and a cyan plate are exposed to obtain a proof image in a conventional positive-positive silver halide color photographic light-sensitive material for color proofing, yellow, magenta and cyan plates are used. The black-and-white halftone dot image plate for printing and the black-and-white halftone dot image plate for black ink have to be overlapped and exposed. Therefore, when trying to obtain a proof for high-definition printing, the reproducibility of neutrality deteriorates and We have found a new problem in that either the dots or the dots of solid color are not reproduced on the plate.

As a result of various studies, we have developed a yellow coloring layer, a magenta coloring layer described in JP-A No. 4-1632,
According to a technique of providing a fourth black plate layer having a maximum spectral sensitivity wavelength different from that of any of the cyan color-developing layers, the above problem is solved to some extent, but its effect is insufficient. all right. Further, regarding this technique, there is no proposal for improving defects by applying it to high-definition printing or printing by FM screening.

In recent years, for the purpose of rapid processing of photographic printing paper, a water-resistant support in which paper is coated with polyolefin has been widely used.

In general, for producing a water resistant support, a method is known in which both sides of a substrate such as paper are extruded and coated with a molten resin layer by a coating method and then cooled and solidified.
At that time, it is known that due to a temperature difference between the substrate and the molten polyolefin, fine irregularities are generated on the surface of the water resistant support, surface smoothness is lost, and unevenness in color shade is generated, resulting in a finished image quality. It has a great adverse effect.

As a method for improving such unevenness in color density, as described in JP-A-3-200139, the unevenness in thickness of a polyolefin-coated support is represented by a PY value of 1.00.
A method of suppressing the thickness to less than μm has been reported.

The inventors of the present invention suppress high PY value of the support to a certain value or less at the time of producing a color proof obtained by four-time exposure through a black and white halftone image, thereby achieving high definition and FM screening. It has been found that not only the reproducibility of small points of the color proof with respect to is improved, but also a stable proof that does not affect the image quality is obtained even if the exposure amount is changed.

[0017]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to produce a color proof from halftone image information obtained by color separation and conversion of halftone images using a silver halide color photographic light-sensitive material.

In the present invention, the color proof is performed by exposing the silver halide color photographic light-sensitive material on the basis of the halftone dot image information consisting of the color-separated yellow image information, magenta image information, cyan image information and black image information.

X10 ³ or more, 400 x 10 ³ or more, more preferably 400
× 10 ^{3 to} 2000 × 10 ³ .

In the present invention, the number of halftone dots can be measured by counting halftone dot images taken by an optical microscope or the like.

The halftone image used in the present invention is particularly effective when it is a halftone image for high-definition printing by the AM screening method which has been generally used conventionally. The present invention is most effective in the case of a halftone image formed by a frequency-modulated so-called FM screen method called a screening method. That is, when a color proof is created by a method other than the present invention from halftone dot image information created by frequency modulation, the average distance between the halftone dots is kept at a certain distance or more when the halftone dot% of the original is small. In the frequency-modulated halftone dot, the average distance between the halftone dots becomes closer to each other more rapidly as compared with the AM modulation, as the halftone dot% increases. This is because the variation of the neutrality is more likely to occur due to the minute deviation of the halftone dots due to the processing and the fine misalignment, and the present invention effectively improves this.

To be Also, the parallelism can be improved by an aggregate of optical fibers.

It is also preferable to perform exposure by laser scanning based on the halftone image information.

Next, the black plate and the magenta plate were brought into close contact with the sample and exposed under the exposure condition-2 shown below. Next, the black plate and the yellow plate were brought into close contact with the sample and exposed under the exposure condition-3 shown below.

To the samples 1-5 to 1-8 obtained as described above, a cyan plate of a halftone original document was brought into close contact with the sample and exposed under the exposure condition-1 shown below. Then, the magenta plate was brought into close contact with the sample and exposed under the exposure condition-2 shown below.

Further, the black plate was brought into close contact with the sample and exposed under the exposure condition-4 shown below.

As a halftone dot original, an original prepared by a screening method consisting of halftone dots of 300 lines per inch was used. An original prepared by the so-called FM screening method in which the size of each halftone dot was approximately 20 μm was also used. The number of halftone dots per inch ² when the halftone dot area ratio was 40% was 90 × 10 ^{3 for the} former document. The latter was 645 × 10 ³ .

Each of the light-sensitive materials thus exposed was processed by the development processing steps and methods shown below to obtain a dye image consisting of halftone dots.

(Exposure condition-1) When exposing each of the light-sensitive materials through a red filter (Ratten No. 25) and an ND filter for white light exposure, the ND filter density is adjusted so that the red density after development processing is Exposure is performed for a minimum of 0.5 seconds with the minimum exposure amount.

However, in the fogging exposure, the surface of the photosensitive material was uniformly exposed to light through the layer of the developing solution having a thickness of 3 mm while being immersed in the developing solution.

A part of another sample was exposed under the same conditions as in the case of the fresh solution treatment and processed in the same manner as in the processing step-1, but the developing solution in the processing step-1 was replenished with the replenished developing solution. Processing was performed using the developing solution, the bleach-fixing solution, and the stabilizing solution after the running processing was performed on Sample 1-2 until the total amount of the replenishing solution was three times as large as that in the developing tank. (Running liquid treatment) Of the obtained images, the image quality based on the black plate was evaluated visually by a magnifying glass with respect to the dot quality at the dot areas of 3% and 40%. The point quality was evaluated. However, the best halftone dot quality is 5
And the relatively inferior halftone dot quality is set to 1, and is relatively scored.
