BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing method for printing on a printing plate which has been exposed to digital image data for printing and which has been subjected to a predetermined developing process before printing on a printing plate. The present invention relates to a color proof creation device for creating a color proof for proofreading.

2. Description of the Related Art
When creating a color proof for print image proofing,
When an analog image, that is, a print film is present, it is general that the print film is directly exposed (contact exposure) in a state of being superimposed on a photosensitive material. In this case, an image equivalent to an image at the time of printing is obtained by considering in advance the characteristics of the photosensitive material (coloring density characteristics and the like). According to this, it is possible to create a proof color proof that is faithful to the print image.

In recent years, CTP (Computer to Pr
With a technique called ess), a print image is obtained as digital image data, and based on this digital image data, a printing plate (PS plate, etc.) can be directly scanned and exposed by a light beam such as a laser to write. Are known. This CT
In P, since there is no print film, the digital image data is used to create a color proof.

However, since the digital image data is composed of a color system (cmyk) suitable for printing, a function of converting the color system into RGB is essential when displaying on a monitor or recording on a photosensitive material. Become. This color conversion function, once
Since it is necessary to use an intermediate color system such as Lab or xyz, the hardware circuit configuration is complicated, and the software memory amount and processing time are enormous.

[0005] Most of the devices for recording an image based on the image data whose color system has been converted include a color printer using a toner and a sublimation type thermal transfer printer. A great deal of labor and time was required to obtain a color proof image with sufficiently faithful colors, including adjustments. It should be noted that, in the category of CTP, there has not been found a configuration for obtaining a color proof image using wet development established as a photographic technique.

In view of the above facts, the present invention facilitates color system conversion from digital image data for printing to digital image data for color proof, and by combining with wet development, color tone faithful to an image at the time of printing. It is an object of the present invention to obtain a color proof creating apparatus capable of obtaining a color proof image.

[0007]

According to a first aspect of the present invention, before printing on a printing plate exposed by digital image data for printing and created by a predetermined developing process,
A color proof creating apparatus for creating a color proof for calibration based on the digital image data for printing using a photosensitive material, wherein the digital image data for printing is converted based on a printing condition profile of a printing plate to be applied. And converts the digital image data into digital image data that does not depend on a printing device, and converts the digital image data into digital image data for exposure that depends on an exposure device based on an exposure condition profile of a photosensitive material applied as a color proof. Color conversion means for converting, digital image data for exposure converted by the color conversion means, data conversion means for converting to halftone image data, based on the halftone image data generated by the data conversion means, Exposure means for exposing a photosensitive material, and photosensitive material exposed by the exposure means The is immersed to a predetermined processing liquid has a developing means for developing process, the.

According to the first aspect of the present invention, since a color proof image is formed by a halftone image, it is similar to the image formation at the time of printing, and is obtained based on the original digital image data for printing. There is no significant difference in the color system between the halftone dot image data and the color proof that is faithful to the original image because of only the difference between the printing device and the exposure device.

The present invention also relates to a yellow image-forming silver halide emulsion layer having different spectral sensitivities, wherein the photosensitive K material contains, on a support, an internal latent image type silver halide particle which is not previously fogged. A direct positive silver halide color photographic light-sensitive material having a light-sensitive laminate comprising at least one magenta image-forming silver halide emulsion layer and at least one cyan image-forming silver halide emulsion layer.

Further, the exposure means uses a light emitting diode which emits light of each color of RGB as a light source.
