[中文适用范围]： 本文件介绍了评估反射彩色照片印刷品因暴露在高相对湿度下导致图像外观变化的测试方法。注：ISO 18949 中描述了在低湿度条件下的测试。观察到的变化与颜色、色调和清晰度下降有关，这些变化是由暴露在高湿度环境中着色剂的水平和垂直扩散引起的。其他与湿度有关的因素，例如霉菌生长，以及物理损坏，例如由于湿度循环造成的卷曲、起皱、开裂或分层，不在本测试方法的范围内。虽然本文件中描述的方法和程序可用于测试任何彩色硬拷贝技术，但它尤其适用于通过将着色剂扩散到图像接收层（例如喷墨或染料扩散过程）或施加到未涂层纤维材料（如纸张）上的系统。 [外文原描述]： This document describes test methods for evaluating reflection colour photographic prints with regard to changes in image appearance resulting from exposure to high relative humidity. NOTE Testing under low humidity conditions is described in ISO 18949. The observed changes relate to colour, tone and loss of sharpness caused by horizontal and vertical diffusion of colorants from exposure to elevated humidity levels. Other humidity-related factors, such as mould and mildew growth, and physical damage, such as curl, cockle, cracking or delamination due to humidity cycling, are outside the scope of this test method. Although the method and procedures described in this document can be used to test any colour hardcopy technology, it is particularly appropriate to systems where the colorants are applied by a mechanism involving the diffusion of colorant into image-receiving layers (for example inkjet or dye diffusion processes) or applied onto uncoated fibrous materials such as paper.
