摘　　要：自动洗片机质量管理的目的是获得高的胶片图像质量，使自动洗片机的性能始终保持在 最佳状态。质量管理的方法是利用标准仪器对胶片感光，经洗片机冲洗，然后对胶片进行测量、记 录数据并绘制灰度曲线，结合标准进行评估，调整洗片机的工作状态，使所测量胶片的本底灰雾、 平均梯度和相对灵敏度等参数都符合或接近ＡＮＳＩ标准所规定的值。本文介绍了洗片机的质量管 理方法、感光度测试方法、灰度曲线的评估法及美国ＡＮＳＩ标准对各种摄影方法所要达到的标准数 据。同时也介绍了胶片图像质量的最佳化评估法。The aim of quality management of auto - processor was to advance film image quality, and kept auto - processor always in good condition. The method of quality management was using standard instrument to expose development and film, then measured parameters and record datum, drew gradient curves, evaluated with criterions and adjusted auto - processor' s working condition, made parameters much as basic fog, average gradient and relative sensitivity according or closing to the criterions that defined by ANSI. The method of quality management, measuring exposed sensitivity, evaluating gradient curves, and standard parameters of some photograph techniques defined by ANSI were reported in this paper. The approach of evaluating image quality opimization was also introduced.
