一、前言许多非银盐感光材料如重氮、微泡、PS版、自由基片等都对紫外光敏感,因此可以在明室中操作,这是其优点。但由于阳光及人造光源(如日光灯、氙灯、水银灯)中都含有一定量的紫外光,因此长期在阳光及人造光源下操作,这些感光材料也会逐渐产生灰雾,影响其使用。在PS版使用中为了消除此缺点,某些使用部门曾在日光灯上刷上黄色染料以滤去紫外光,但它严重影响照明以及对材料上图象的观看。为此,我们研

I. INTRODUCTION Many non-silver photosensitive materials such as diazo, microbubbles, PS plates and free-radical sheets are sensitive to UV light and therefore can be operated in bright room, which is their advantage. However, since sunlight and artificial light sources (such as fluorescent lamps, xenon lamps and mercury lamps) contain a certain amount of ultraviolet light, they are often operated under sunlight and artificial light sources. These photosensitive materials also gradually generate fog and affect their use. In order to eliminate this disadvantage in the use of the PS version, some users have brushed a yellow dye on a fluorescent lamp to filter out UV light, but it seriously affects the lighting and the viewing of the images on the material. To this end, we research
