我国彩色电影正片的使用,这几年经历了较大的变化。1986年以前,在国内发行的多层彩色电影拷贝中水溶彩色正片占主要地位。原因是生产水溶彩色正片的方法较简便,成本低,技术较成熟;但他与油溶彩正片、染印法拷贝相比较,色彩还原不真实,色光不鲜艳(如陈旧拷贝)又成为一致公认的缺点。经几年来国内有关电影胶片厂的努力,这项油溶彩正片取代水溶彩正片的升级换代工作终于在1986年宣告完成。1987年油溶彩正片的质量又有进一步的提高。本文就国产油溶彩正片的性能、质量和改进展望作一阐述。
The use of positive color film in China has undergone major changes in recent years. Prior to 1986, water-soluble color print films dominated the domestic distribution of multi-layered color film copies. The reason is that the method of producing water-soluble color positive film is relatively simple, the cost is low, and the technology is relatively mature. However, compared with oil-soluble color positive film and dye copy method, the color reproduction is not true and the shades of color (such as old copy) Shortcomings. After several years of efforts made by the domestic film studio, the upgrading of the oil-soluble color film instead of the water-soluble color film was finally announced in 1986. In 1987 the quality of oil-soluble color film has been further improved. This article elaborates on the performance, quality and improvement of domestic oil-soluble color film.
