They are Jab values (CICAM02).
My black point is (.ti2 file): "Q3" 0.0000 0.0000 0.0000 1.0000 1.0000 1.000 The reading of this patch with the ColorMunki software gives me this result in L*a*b* values: L*=4.6 Using profcheck I get this result for the Q3 patch: [0.219403] 5: 0.000000 0.000000 0.000000 -> 4.715842 1.202572 1.658739 should be 4.812903 1.350490 1.624429 So I can't understand what is that black point about.
See above. There is an appearance conversion between D50 L*a*b* values and the CIECAM02 Jab values, hence the difference. If you use xicclu -pj with the appropriate viewing conditions set, you should get matching numbers. Graeme Gill.
