Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is suitable for producing a proof color image (color proof) from a plurality of black and white halftone images obtained by color separation and halftone image conversion in a color plate making / printing process. The present invention relates to a silver halide photographic color light-sensitive material for producing a color proof 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 superimposed on a single support. A method of obtaining a colored image by toner development utilizing the tackiness of a photopolymerizable material is disclosed in US Pat. No.582,327, No.3,6
07,264 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 making it
It is known from JP-A-7-27441 and JP-A-56-501217.

Further, a method of transferring each colored image obtained by exposing and developing a corresponding color separation film using a photosensitive colored sheet and forming the same on one support is disclosed in Japanese Unexamined Patent Publication No.
No. 9-97140. 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 such a disadvantage, a method of producing a color proof by using a silver halide color photographic light-sensitive material having a white support is disclosed in Japanese Patent Application Laid-Open No. 56-13313.
No. 9, No. 56-104335, No. 62-280746
No. 62-280747 and No. 62-280748.
Nos. 62-280747 and 62-280750
And No. 62-28049.

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.

However, in this technique, when the color image is approximated to the printed matter, the density of the black image such as characters is insufficient as compared with the printed matter, and the density of the black image such as the characters is increased to approximate the density of the printed matter. If the measures are taken, there is a drawback that the degree of approximation of the color image of the printed matter deteriorates and it is difficult to satisfy both of them.

In recent years, from the viewpoint of improving the image quality of printed matter, there has been a strong demand for practical application of high-definition plate making and printing. However, the conditions for reproducing fine dots are strict, and it is desired to improve their reproducibility. However, the reality is that it has not yet become popular. Furthermore, in terms of obtaining a color proof for high-definition printing as well, there is a point that improvements need to be made as in plate making and printing. In particular, in the color proof to which the silver salt photographic method is applied, even if the small dot reproducibility is good, when it is applied in high definition, unfavorable reproduction is caused from the viewpoint of dot reproducibility (dot gain), and improvement is desired. Further, there are problems of deterioration of reproducibility of gray neutrality, fluctuation of development processing conditions, and fluctuation of neutrality due to minute deviation of register marks.

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.
7) As described in detail in 6, p49, etc., the frequency (F) is used to describe the nature of the wave, and the number of waves (frequency) is determined. The concept of amplitude (A) is used to describe the height of a wave. Applying the concept of frequency and the concept of amplitude to screening,
The screen frequency (F) 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. Conventional screening produces points of different size, as is well known, 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.

JP-A-1-260629 and JP-A-61-161
233732 and JP-A-4-1632 describe a silver halide color photographic light-sensitive material having four emulsion layers of YMC black having different spectral sensitivities. However, the application to high-definition printing, which is a high-quality printing that can simply obtain an image similar to a printed matter, and the printing by FM screening, is not mentioned at all, and there is no description about the drawbacks due to the application to the high-quality printing. Absent.

On the other hand, it is desired to remove benzyl alcohol, which requires a long time for dissolution, in order to obtain a development processing liquid with improved usability by reducing the load of the dissolution of the developing liquid. Further, when benzyl alcohol is brought into a bleach-fixing bath, which is a subsequent bath, together with the developing solution and accumulates therein, it causes a leuco body formation depending on the kind of the cyan dye, which causes a decrease in color density. However, by simply removing this, when applied to a color proof composed of a halftone dot image, for example, when the pH of the developer is changed or the running development processing condition for continuing continuous processing is changed, the black halftone image It was found that the fluctuation of the neutrality becomes large.

[0015]

The amount of these compounds added to the color developing solution is 0.1 to 20 g, preferably 0.5 to 10 g, per liter of the color developing solution.

In the present invention, when a large amount of a light-sensitive material is processed, the color developing solution is preferably subjected to a developing process while being replenished. In the present invention, the replenishing amount of the color developing solution is preferably 350 cc or less per 1 m ^{2 of the} photosensitive material to be processed. The replenishment amount of color developer is 3
It is more preferably 00 cc or less, further preferably 250 cc or less.

In the present invention, the color proof is performed by exposing the silver halide photographic color 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. In the process of creating the image, at least a part of the halftone dot image information is 1 inch ² when the halftone dot area ratio is 40%.
One halftone image is converted so that the number of halftone dots per dot is 200 × 10 ³ or more. It is preferably 300 × 10 ³ or more, 400 × 10 ³ or more, and more preferably 400 × 10 ^{3 to} 2000 × 10 ³ .

In the present invention, the number of the 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 fluctuation of the neutrality is more likely to occur due to the fine deviation of the register marks whose halftone dot% is the reference for processing and alignment, and this is effectively improved by the present invention.

In the present invention, the halftone dot image information is a halftone dot image recorded on a film, and the silver halide photographic light-sensitive material is brought into close contact with the film and is exposed by scanning with a light source. Is preferred. A vacuum adhesion method can be preferably used for adhesion.

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.

The present invention will be described in more detail below.

As the reflection support preferably used in the present invention, a base paper is used as a base, and a polyolefin resin is laminated on both surfaces thereof is preferably used.

Further, additives such as a sizing agent, a fixing agent, a toughening agent, a filler, an antistatic agent and a dye, which are generally used in papermaking, may be added to the support, and the surface size may be adjusted. An agent, a surface-strengthening agent, an antistatic agent, or the like may be appropriately applied to the surface.

When forming a laminate on the front and back of the support,
Generally, in order to improve the flatness of the developed photographic paper in a normal environment, a means such as slightly increasing the density of the resin layer on the front side or increasing the laminating amount on the back side rather than the front side is used.

In general, the front and back surfaces of the support can be laminated by forming the polyolefin resin composition on the support by melt extrusion coating. In addition, it is preferable to perform corona discharge treatment, flame treatment, or the like on the surface of the support or on both the front and back surfaces as necessary.

It is more preferable to add a hollow fine particle polymer or a high boiling point organic solvent to the hydrophilic colloid layer containing a white pigment, since the sharpness and / or curl resistance can be improved.

As the reflective support, a synthetic resin film support such as polypropylene whose surface is further coated with polyolefin can be used.

The thickness of the reflective support is not particularly limited, but 8
Those having a thickness of 0 to 160 μm are preferably used, and particularly 90
It is more preferably about 130 μm thick.

The surface shape of the reflective support may be smooth or have an appropriate surface roughness, but it is preferable to select a reflective support having a gloss close to that of a printed matter. For example, JIS-B 0601-197

[0202]

[Table 3]

From the results shown in Table 3, it can be seen that the images produced by the method of the present invention have small fluctuations in neutrality even when the replenishment is low. Further, it is clear that the neutrality is stable even in the running state by using the compound of the present invention.

Example-3 Sample-2 was prepared according to the sample 1-1 prepared in Example-1. However, the emulsion shown below was additionally added to the eighth blue-sensitive layer of Sample 1-1. The following emulsion was additionally added to the fourth green sensitive layer of Sample 1-1. Furthermore, Sample 1-1
The following emulsion was additionally added to the second red-sensitive layer. Sample 2 was prepared in the same manner as sample 1-1 except for the above.

Eighth layer Infrared photosensitive silver chlorobromide emulsion (EM-IR) 0.3 (Blue sensitive layer) Fourth layer Infrared photosensitive silver chlorobromide emulsion (EM-IR) 0.28 (Green Sensitive layer) Second layer Infrared-sensitive silver chlorobromide emulsion (EM-IR) 0.25 (red sensitive layer) A cyan plate of an original halftone dot was brought into close contact with the obtained sample-2. It was exposed under the exposure condition -1 described in -1. Then, the magenta plate was brought into close contact with the sample and exposed under the exposure condition-2. Then, the yellow plate was brought into close contact with the sample and exposed under the exposure condition-3. Further, the black plate was brought into close contact with the sample and exposed under the exposure condition-4.

For the sample 1-1 produced in Example-1,
Of the original halftone dots, a black plate and a cyan plate were brought into close contact with the sample and exposed under the above exposure condition-1. Next, the black plate and the magenta plate were brought into close contact with the sample and exposed under the exposure condition-2. Next, the black plate and the yellow plate were brought into close contact with the sample and exposed under the above exposure condition-3.

As the halftone dot original, the same original as that used in Example-1 was used.

When performing this exposure, the entire surface to be exposed was simultaneously irradiated with the light from the light source to perform the exposure. (Simultaneous whole surface exposure) Next, a slit-shaped exposure window is installed in the light source, and the light irradiated through the window is used for exposure, but the exposure is performed by scanning the photosensitive material with the exposure unit. went. ...
(Scanning exposure) Further, the above scanning exposure was repeated, but the exposure was performed on the photosensitive material side of the exposure window through a means for improving the light parallelism of the honeycomb structure. ... (Honeycomb scanning exposure) In each of the above-mentioned simultaneous whole surface exposure, scanning exposure, and honeycomb scanning exposure, the registration mark position that indicates the reference of the original position for the yellow plate, magenta plate, cyan plate, and black plate of the document is the reference point. Were exposed so as to be offset by 20 μm from each other in arbitrary directions.

The exposed sample was treated with a new developer solution having a benzyl alcohol content of 0 cc / liter under the processing condition-1 of Example-1.

With respect to the obtained image, the neutrality was measured with respect to an image in which each of the yellow plate, the magenta plate, the cyan plate and the black plate was 50%. Here, the results of measuring and evaluating D _R / D _G as an index of neutrality are shown. However, D _R / D _G when the register mark of the halftone dot is in the normal position is set to 100, respectively, and shown in Table 4.

[0211]

[Table 4]

As is clear from Table 4, in the case of an image produced by a method other than the present invention, when an FM screening original is used, the misalignment of the register marks greatly deteriorates the neutrality. The resulting image is
Fluctuations in neutrality are kept small. Moreover, a stable image with neutrality can be obtained by scanning exposure rather than whole surface exposure.

Sample-2 according to the present invention, when the original of the FM screen was used for the sample-2, the neutrality reproduction was superior to the simultaneous exposure on the whole surface in the scanning exposure, and further, when the means for improving the parallelism was used. It turns out that it will be improved.

[0214]

It can be seen that the image produced by the method of the present invention has a high neutrality and is stable even if there is a variation in processing or a difference in the halftone dot forming method of the original. Further, even if the replenishment is low, the fluctuation of the neutrality is suppressed to a small level, and the neutrality is stable even in the running state by using the hydroxylamine compound in the developing solution. Even if the registration mark is misaligned, the fluctuation of the neutrality is suppressed to a small level, and moreover, the stable exposure of the image is obtained by the scanning exposure rather than the whole surface exposure.
