标准范围

本文件描述了评估反射彩色照相印刷品因暴露于高相对湿度而导致的图像外观变化的测试方法。笔记？ISO 18949中描述了低湿度条件下的测试。观察到的变化与颜色、色调和清晰度损失有关，这是由暴露于升高的湿度水平引起的着色剂的水平和垂直扩散引起的。其他与湿度相关的因素，如霉菌和霉菌生长，以及物理损伤，如由于湿度循环导致的卷曲、起皱、开裂或分层，不在本试验方法的范围内。尽管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，但其特别适用于其中着色剂通过涉及将着色剂扩散到图像接收层中的机制(例如喷墨或染料扩散过程)施加或施加到未涂覆的纤维材料如纸上的系统。

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.
