本文件规定了一组标准大色域彩色图像（编码为16位CIELAB数字数据），可用于评估编码、图像处理（包括转换、压缩和解压缩）、在彩色监视器上显示和打印期间图像质量的变化。这些图像可用于研究、测试和评估输出系统，如打印机、颜色管理系统和颜色配置文件。

This document specifies a set of standard large gamut colour images (encoded as 16-bit CIELAB digital data) that can be used for the evaluation of changes in image quality during coding, image processing (including transformation, compression and decompression), displaying on a colour monitor and printing. These images can be used for research, testing and assessing of output systems such as printers, colour management systems and colour profiles.
