it seems you’re using the same piece of software as comes with Argyllcms (colprof)?
I tried it and it seem to work but I see at least one thing that is begging for a question, it seems like these profiles are only useful for soft proofing, right?
In ColorThink Pro (CTP), the absolute colorimetric rendering intent is useless which suggest something wrong with the profile. All other intent, seem ok and are exactly the same as relative colorimetric intent. Also notice the primaries are wrong as per CTP.
./colprof -d pc -R -Zb -v -C"Your Name Here" -A"Your Name Here" -Zbr -D"$sname" -qm -cmt -dpp $fname
This is your original command line in the shell script you provided. I wonder why you have 2 -d argument, one (-d pc) for “Critical print evaluation environment (ISO-3664 P1)” and one (-d pp) for the “Practical Reflection Print (ISO-3664 P2)” I don’t pretend to be knowledgeable about this, just curious. Same with -Z as well.
The “TI3” file provide 656 “sets” , 256 gray patches and the rest are color patches, I suppose you have to do this for colprof to work,right?
I see the lowest L* measurement is 12.8, I hope this is for a matte paper? That’s from the original data in PP 2.2.1 .
Last question, the tab “I1Profiler ICC Data”, is this one to be used to create the profile using I1 Profiler?
