【摘要】 本文扼要总结了印刷制版用的明室拷贝片研制工作中所解决的主要技术课题和取得的成果,如;双注法制备的高分散性细颗粒乳剂、低照度互易律失效明显、采用增粘剂以降低胶银比,实现薄层涂布等等。试验数据表明:基于上述研究成果制成的印刷制版明室拷贝片在性能上已达到进口胶片水平。更多还原

【Abstract】 This paper presents a summary of technical problems solved and achievements accomplished during the research into making graphic arts light room duplicating film e. g-highly mono-dispersed ultra-fine grains emulsion prepared by double-jet method,significant low-intensity reciprocity law failure,thin layer coating resulted by using viscosity intensifier and low gelatin-silver ratio etc. . Testing data showed that the graphic arts light room duplicating film prepared on the basis of the above achievements has characteristics similar to imported films.更多还原
