一、缩微胶片生产流程及影响质量的因素 胶片质量最关键所在是拍摄与冲洗。缩微品质量受到设备、使用材料以及人为的诸方面因素的影响,其中工艺参数的取值直接影响着质量,可称为关键之关键,因此,生产缩微品之前,必须首先正确选择工艺参数（光圈、倍率、冲洗速度、拷贝速度）使其检验值达到国家标准,以取得较好质量的档案缩微品。 First, the microfilm production process and the quality of the factors Film quality is the key to shooting and washing. The quality of the microfilm is affected by the factors of equipment, materials used and man-made factors. The value of the process parameters directly affects the quality and can be called the key. Therefore, before the microfilm is produced, the process parameters (aperture , Rate, washing speed, copy speed) to test the national standards, in order to obtain better quality file microfilm.
