ISO 17972-4:2018定义了油墨光谱测量数据的交换格式，以提供一种描述专色油墨特征的方法，从而对使用这些油墨设计的产品进行可靠的打印和打样。只有各向同性（纸质）基材在本文件范围内，仅限于印刷时使用相同油墨和纸张组合的应用领域。 ISO 17972-4:2018描述了在CxF框架内使用CustomResource元素来定义用于exchange的最小和推荐数据集。

ISO 17972-4:2018 defines an exchange format for spectral measurement data of inks to provide a means to characterise spot colour inks to allow reliable printing and proofing of products that have been designed using these inks. Only isotropic (paper-like) substrates are within the scope of this document, which is limited to application areas where the same ink and paper combination that has been characterised is used when printing. ISO 17972-4:2018 describes the use of a CustomResource element within the CxF framework to define a minimum and recommended set of data for exchange.
