I didn’t analyze your posting just did a FOGRA52 based profile using the basICColor engine. Is the attached plot more what you’d expect?

Claas Yes… but this is what I get with i1Profiler for MaxK: And for Full Black: The yellow is either wrong or gone! Even with standard K generation, i1Profiler still produces a profile with an odd yellow — max 35% at L30 and dropping to 10% at L0 for Perceptual. I’ve never seen i1Profiler produce such drastically different results from the ECI profiles with any other data set until 52. ArgyllCMS is also giving us similarly odd Y too.
