Hi !

I did a printer profilling vhit V110, see below.
  When using Perseptual rending the black and dark grey, below aprox RGB
10,10,10 turned into a nice blue color, 
mostly like a "shadow warning" 
If Relativ or Absolut rending this dont happend, now it is dark
grey-black.

------------

I have earlier made a profile whit V104, and whit this a BW print tures
a little against purplish, 
but not so much like RC1, now whit V110 the bw and outher turns against
a little sepia.
This is just a note, perhaps it has somthing to do whit my process.

Workflow:
vista 32b
(higlites, rewritten from same bat-files)

create calibration target:
targen -v -d4 -g512 -s512  -f0    name 
printtarg -v -a0.600 -s -iSS -t -pA4    name

create cal-file:
scanin -c -v    target.tif   reference.cht     inscanprofil    name
printcal -v  -i  name

create profiling target inkl cal_file:
targen -v -d4 -g512   -f4048    name 
printtarg -v -a0.504 -s -iSS   -t   -pA4  -Kcal_file    name

create profile:
scanin -c -v   target.tif     reference.cht    inscanprofil   outprofil 
colprof -v -D"desc" -C"copr" -S colprofinprofil(sRGB)    -cmt    -dpp
outprofil
