Look at it from another point of view. The european/german organisations FOGRA, bvdm and ECI, which are mainly involved into the research of all that Process Standard things and the resulting ISO 12647 worldwide norms, have a big problem:
The Delta E ab is the only one that can be used in juristic way to judge color consistancy. It is a fact that Delta E 2000 or CMC or something like that is more sophisticated, but no court in the world would accept it, because they are not fixed in an ISO norm.

Thank you for the clarification, Rolf.

>From what you say, it appears to me that for private use (such as photo-quality inkjet prints), Delta E 2000 can be seen as the better methodology, while Delta E ab might be advisable when proofing to something like SWOP, due to the lack of ISO standardization for Delta E 2000. Is that a fair statement?

Best regards.
