Use the Substrate Correction tool to convert measurements taken on a backing material, a black substrate for example, as if they were taken on another backing, a white substrate for example, as described in ISO 13655:2009, Annex A. You can also use it to convert standard or custom colorimetric aims data sets, the aims of ISO 12647-2 for example, when your substrate/paper is not within tolerance, as described in ISO/PAS 15339-1.
