Hi,

How does this relate to the line earlier of:> Black point XYZ = 0.00382897 
0.00359473
0.00437237, Lab = 3.247107 1.465492 -2.656503

Why wouldn't the destination black L value be 3.247 or 8.53 as opposed to 
9.45?  Just> trying to understand what is going on under the hood a bit.
The first value (BP) is in L*a*b* space. By default the gamut mapping is in 
CIECAM02
appearance space, so you can't directly compare the two sets of values.

Cheers,
