ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a method for processing a silver halide photographic light-sensitive material (hereinafter also referred to light-sensitive material), and particularly to a method for rapidly processing large sized light-sensitive material for graphic arts use by an automatic processor without formation of stain on the formed image.
BACKGROUND OF THE INVENTION
Recently, photographic light-sensitive materials for graphic arts are often processed by an automatic processor combined with a laser image output apparatus, a so-called image-setter. The processed light-sensitive material outputting an image output by the image-setter is often used as a final original image for printing to a lithographic printing plate. Therefore, clear images become an important property of the processed light-sensitive material.
On the other hand, the exposure by the image-setter can be rapidly performed. Accordingly, it requires shortening the time for processing by raising the transportation speed of the automatic processor to respond to the speed of the exposing process. Some problems such as adhesion of stains of remaining color and formation of roller marks on the processed light-sensitive material and jamming of the light-sensitive material, are occurring during high speed transportation and processing to correspond to the output speed of the image-setter. Such problems are markedly produced in silver halide photographic light sensitive materials having an absorption maximum at the wavelength of 600 to 800 nm. Specifically in silver halide photographic light sensitive materials containing a compound represented by formulas (1) to (6), described below, such problems occur markedly.
SUMMARY OF THE INVENTION
The object of the invention is to provide a method for processing a light-sensitive material for use in graphic arts by which the light-sensitive material can be processed without any problem such as formation of stain, residual color, unsuitable transportation and formation of roller marks even during the rapid processing so as to correspond to the output speed by the image-setter.
The object of the invention can be accomplished by the following constitution:
1. A method for processing a silver halide photographic light sensitive material in an automatic processor comprising the steps of:
(a) developing an exposed silver halide photographic light sensitive material with a developing solution in the automatic processor,
(b) fixing the developed silver halide photographic material with a fixing solution in the automatic processor,
(c) washing the fixed silver halide photographic material with water in the automatic processor, and
(d) drying the washed silver halide photographic material in the automatic processor,
wherein the silver halide photographic material exhibits an absorption maximum at a wavelength of 600 to 800 nm; the automatic processor comprises at least a roller provided after completing the step of washing, the roller is brought into contact with the silver halide photographic material, and the surface of the roller is covered with a material exhibiting a contact angle with water(&thgr;) of more than 0° and less than 60° (i.e., within the range of 0°<&thgr;<60°);
