标准范围

ISO 18946:2012描述了评估反射彩色照相印刷品因暴露于低和高相对湿度而导致的图像外观变化的测试方法。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。其他湿度相关因素超出了本试验方法的范围。ISO 18946:2012中描述的方法和程序特别适用于通过涉及着色剂扩散到图像接收层中的机制施加着色剂的系统，以及适用于易发生Dmin变黄的某些类型的喷墨介质。

ISO 18946:2012 describes test methods for evaluating reflection colour photographic prints with regard to changes in image appearance resulting from exposure to both low and high relative humidity.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 are outside the scope of this test method.The method and procedures described in ISO 18946:2012 are particularly appropriate to systems where the colorants are applied by a mechanism involving the diffusion of colorant into image-receiving layers and to certain types of inkjet media that are susceptible to D_min yellowing.
