[argyllcms] Fakeread with cmyk profile...

Dear group,

Long time have I been a RGB only guy, and life was simple ;)
Now, I am descending (ascending?) into the CMYK world and having some
problems...

I would like to use the fakeread utility to adjust/scale the blackpoint of
a particular output CMYK profile.
(All my previous attepts with RGB profiles were successful.)

I do not have any chart readings of this profile, nor are they embedded.
The actual blackpoint of the device is approximately 10.5,1.5,1.0 (Lab).

So I use:
* targen -s17 -g33 -e8 -d4 -f4092 -I -cMy_CMYK_Profile.icc target (.ti1)
* fakeread -l -b0,0,0 My_CMYK_Profile.icc target (.ti3).
* colprof -v target (.icm).

Now the thing is that *some* scaling is going on depending on the -b
parameter during fakeread, but the actual blackpoint is *never* lower than
the initial 10.5.

I'm at a loss here!

Can anyone help?

Best regards,
Auke Nauta
