はなり得ないのが現状である。For this reason, various systems have been announced and sold in addition to trial printing called proof printing for the purpose of these checks. Examples include those using CRT, those using non-silver salt photosensitive materials such as photopolymers and diazo, those using dry toner to form images, and electrophotography. However, these calibration systems generally require a long time to complete a single calibration, and their material costs are high.
Currently, there are problems such as poor workability, and it is not possible to provide a system that is sufficient for practical use.

No. 62-280749, No. 62-280750, No. 62-280849, etc., describe a method of obtaining a calibration material on a color photosensitive material using a photographing system using a projection lens. These are so-called "bright room specifications" that allow work to be carried out in a normal room; the photosensitive material remains inside the device, and the exposure operation can be performed with a normal knife without the need for a dark room. . Therefore, it is possible to perform color calibration in a short time and at low cost, and it has better characteristics than other calibration systems.

ー感光材料の画像から、ポジ原稿の網%の正誤性につい
て正しい判断を加えることが非常に困難であった。However, when a positive-working silver halide photosensitive material is used in such a method, not only does the fog density become high because the positive-working silver halide photosensitive material tends to cause negative fog, but also a low The average gradation level on the density side tends to be low, and when used as a color proofing material for printing halftone images, the density difference between the fog density and the color density in the halftone dots will increase in areas with low halftone percentage. As a result, the net image becomes extremely blurred. As a result, it has been extremely difficult to make a correct judgment as to whether the dot percentage of a positive original is correct or incorrect from an image of a color photosensitive material.

ができなかった。Furthermore, in color photosensitive materials that use special dyes called color couplers, it is generally extremely important to improve sharpness, so the image density of each layer of the color photosensitive material is usually maintained at 2.0 or higher. . However,
If you use this as is as a color proof for a trial print, the color tone will be too strong and will not match the tone of the actual print, resulting in a completely different finished quality, and the color that was originally intended will be It was not possible to accurately check the situation.

できる。The above problem was solved by subjecting the color original to component color separation and converting it into a halftone dot image, which was obtained by closely exposing a transmission type black and white halftone image to a chromogenic color photographic light-sensitive material with a continuous tone density curve. , in the method of color development processing; solid density Dra in each coloring layer of the color photographic light-sensitive material after the color development processing is 2.0 or less, and the average gradation degree on the low density side is 1.7 or more. It can be solved by doing

値である。In the present invention, the average gradation on the low density side is defined as follows. That is, as shown in FIG. 1, in the characteristic curve showing the relationship between the absorption density and 1ogE, which is the logarithmic representation of the exposure amount, from Fog+0.50 to Fog+0.02
It is defined as the absolute value of the low density range (0,05-0,02) divided by the exposure amount difference (ba) required to reproduce this range. That is, (1) Formula % Formula % Note that b is the fogE value when Fog+0.50, a is the #ogE value when Fog+0.02, and F is the fog density value.

際の印刷物との色調が異ってしまう。In the present invention, a transmission type black and white halftone dot image obtained by separating the component colors from a color original and converting it into a halftone dot image is closely exposed to a chromogenic color photographic light-sensitive material having a continuous tone density curve. Then, in the method of color development processing, the solid density Dm in each coloring layer of the color photographic light-sensitive material after the color development processing is set to 2.0 or less. If the solid density Dm exceeds 2.0, the obtained color proof will differ in tone from the actual printed matter.

膜化するなどの方法を用いることができる。The solid density (maximum image density) Dm can be measured using various densitometers. It is difficult to define a preferable lower limit value of this solid density, especially since the density of the yellow coloring layer varies considerably depending on the filter used in the densitometer, but preferably a type using a lasoten filter such as 47B. It is preferable that the value is 0.8 or more for a type of densitometer, and 1.3 or more for a type of densitometer that uses an interference filter such as an SPI filter. Further, the concentration at this time means absorption concentration. As a method for obtaining the solid density Dra according to the present invention, methods such as reducing the amount of coupler or making the photosensitive layer thinner can be used, as is well known.

周辺がぼける傾向となり、網点品質が劣る結果となる。On the other hand, in the present invention, as described above, the average gradation on the low density side is 1.7 or more, more preferably 1.8 or more. The average gradation on the low density side is the dot (halftone dot) in halftone dot reproduction when creating a color proof.
The present inventors have discovered that this is a major factor that determines the sharpness of the image. The smaller this value is, the more the area around the halftone dot tends to be blurred, resulting in poorer halftone dot quality.

たがって、低濃度側での平均階調度は、167以上とす
るのが要求される。Especially for small dots, the area ratio of such peripheral blurring is counted at a high rate compared to the area of the halftone dot itself, which not only makes it difficult to accurately measure the halftone percentage, but also makes it difficult to accurately measure the halftone percentage. The distinction from the dot portion becomes unclear, and as a result, the sharpness of the image of the small dot portion becomes significantly inferior. Therefore, the average gradation degree on the low density side is required to be 167 or more.

ることができる。The method for creating a color proof of the present invention can also be applied to a method in which a digital signal is directly recorded as an image using a laser beam or the like, rather than a method in which a transmission-type separated black and white halftone dot image is closely exposed. In recent years, when creating transmission-type separated black-and-white halftone images, it has become common practice to process digital signals and record them using a laser output device called a scanner. It is possible to obtain similar results by outputting. At this time, correction can be added to the digital signal for the purpose of correcting the finished color tone.

ルーフ材料としてはあまり好ましくない。However, in the photographing system, due to the method of photographing, lens flare and the like are added, making it difficult to obtain good halftone reproduction. In other words, a phenomenon occurs in which the dots do not appear or are crushed on the small dot and large black sides, respectively. Therefore, the apparent average gradation becomes soft, which is not very desirable as a color proof material where tone is important.

In this case, it is desirable that the average gradation T of the entire characteristic curve (the slope of the linear portion of the characteristic curve) be 2.0 or more, preferably 2.1 or more. By maintaining such a high average gradation level, the sharpness of the halftone dots (the difference in density between the middle of the halftone dots and the background fog, which is called sharpness), which is required for a photosensitive material that produces halftone images, which is conventionally known as monochrome film, is maintained. or,
Roughness around the halftone dots can be maintained well.

ドンなどを挙げることができる。In the present invention, specific means for increasing the average gradation degree in the low density region to 1°7 or more, preferably 1.8 or more include using a monodispersed silver halide emulsion and using pyrazolidone, which is a heterocyclic developing agent. An example of this is to add a very small amount of the system to the developer. Specifically, the amount added here is 40 to 200 cm per liter of developer, preferably 5
It is preferable to add 0 to 100 hours. Virapritone compounds are compounds with a pyrazolidone ring as the core, and specifically include 1-phenyl-3-pyrazolidone, 1p-)dyl-3-pyrazolidone, 5-phenyl-3-pyrazolidone, and 5-methyl-3-pyrazolidone.

液として広く利用されている。It is known to add such a pyrazolidone compound to a monochrome developer as an auxiliary developing agent. In general, pyrazolidone compounds are acute developing agents, and therefore the high-density area and the low-density area are developed almost simultaneously, resulting in a soft tone. The PQ developer utilizes this super-additivity, combining this with a slow developing agent that rapidly develops only high-density areas and extremely slows development of low-density areas, and is currently widely used as a monochrome developer. It's being used.

In the present invention, by adding a small amount of a pyrazolidone compound to a color developer consisting of an acute developing agent such as P-phenylenediamines and P-aminephenols, the effect of suppressing low density areas can be obtained. This is an effect that could not have been predicted in the past. In addition, the amount of the pyrazolidone compound added here is the same as that of ordinary P.
The amount is considerably smaller than that of Q developer.
