世界各国长期以来大量生产了各种银盐感光材料。近年来在面临日益严重的“银荒”情况下,又研制了多种非银盐感光材料。为进一步发展我国的印刷出版事业,现将一些国外印刷制版用感光材料介绍如下: 一、银盐印刷制版感光材料银盐印刷胶片在整个银盐感光材料生产中的比重很大。以日本1976年的胶片产量为例,其中印刷片占36％,X光片占35％,一般彩色胶片占12％,电影胶片(彩色与黑白)占11％,一般黑白胶片占6％。印刷片
Various countries in the world have long been producing a large number of silver salt photosensitive materials. In recent years in the face of increasingly serious “silver shortage” situation, but also developed a variety of non-silver salt photosensitive material. In order to further develop the printing and publishing industry in our country, a few foreign photosensitive materials for printing and plate making are introduced as follows: 1. Silver salt printing and plate making photosensitive material Silver salt printing film has a large proportion in the production of silver salt photosensitive material. Taking the film production of Japan in 1976 as an example, 36% of printing films, 35% of X-ray films, 12% of general color film, 11% of motion picture film (color and black and white), and 6% of general black and white film. Printed film
