I'm sure there's a perfectly reasonable explanation to do with profiles or something and I'm not suggesting there is a problem with the program, just my understanding.

Here's some examples...

Black Values (Yes I acknowledge the difference between screen/light versus print/ink)
RGB R-0 G-0 B-0
HSV H-0 S-0 V-0
HEX 000000
CMYK C-74.1 M-68.3 Y-66.6 K89.8 ?

Why would CMYK not be 0 0 0 100 for example?

White Values
RGB R-100 G-100 B-100
HSV H-0 S-0 V-100
HEX ffffff
CMYK C-4 M-0.4 Y-0 K0 ?

Why would CMYK not be 0 0 0 0 for example?

Thanks for any insight.
