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).
Right. Does the profile have a black point tag that has this value in it ?
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!
My guess is that the profile has no black point tag, so the ICC default of 0,0,0 is used instead. Since you've set a black target of 0,0,0, nothing changes. [ The next release will take a somewhat smarter approach, and determine a black point if the profile is missing the black point tag. ] Graeme Gill.
