Roger, the CIELAB values for green and blue in FOGRA39 are *not* the same as in FOGRA27. The values of ISO 12647-2:2004 Amd1 (2007) are modified in FOGRA39, according to best practice results. This is in compliance with ISO requirements. Secondaries (RGB) in ISO 12647 are informative, not normative.

Any reason why the dataset has not been recalculated or updated? Unless I really need a pair of new glasses ;-) MfG, Roger Breton _______________________________________________ ECI-EN mailing list ECI-EN(a)lists.callassoftware.com http://lists.callassoftware.com/mailman/listinfo/eci-en
