The International Standards Organisation (ISO) is responsible for creating and maintaining standard procedures for a wide variety of processes, not just for printing. ISO 12647 relates specifically to a family of standards that apply to a variety of printing processes. ISO 12647-7 specifies the requirements for systems that are used to produce hard-copy digital proofs intended to simulate a printing condition defined by a set of characterisation data. The most recent update of this standard was in 2016. All our proofs are compliant to ISO 12647-7-2016. http://www.colorwiki.com/wiki/ISO_12647
