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.
