METHOD FOR EXPOSING AND COPYING PHOTOGRAPHIC SENSITIVE MATERIAL AND EXPOSURE DEVICE TO BE USED FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method to decrease unevenness in density due to the imprinting of Newton rings by modifying the exposure method without using a liquid for prevention of Newton rings or without matting the surface of a photosensitive material, and to provide a system used for the method.;SOLUTION: In the method for exposing and copying, when an image original having image information formed by the difference in density is overlapped with another photosensitive material and copied by exposure, the photosensitive material is irradiated with light from a light source through a filter having the transmittance almost reversal to the relative sensitivity of the photosensitive material.;COPYRIGHT: (C)2002,JPO
