Hello again!
I started experimenting with Argyll's FWA compensation. I have a question.
What is the difference in the resulting profile between the following 3
options of colprof?
1. -f -iD50
2. -fM0 -iD50
3. not using the -f switch
Thanks!

HI Kamil,
-5b with M0 is not so bad.
Thanks / Roger

Hi Roger,
it depends ... :)
results vary (and Lab is not sufficient parameter here), but mostly
around -5b under M0
cheers, K.

Hi Kamil,
Did you specified what Lab (M0) reading you get on your OBA paper?

Hi Panagiotis,
i am getting nice results when measuring under M0 and with no
compensation.
In this case, resulting print is not perfectly neutral under daylight,
there
is slightly cold tone instead, but people are mostly satisfied. And when
print are illuminated with light without UV, the change toward to the warm
tone is smaller. Technically speaking, it is something like a "middle of
the
range" as Graeme pointed.
Also good idea is higher GCR, as Daniel suggest, but note, that you can't
avoid changes cold/warm with any GCR setup..What is your workflow? With
some
RIP, it could be possible to print on your printer in CMYK mode, it is
just
a matter of driver/RIP (imho, Colorproof XF can do this).
Kudos to Samule for Acrylite suggestion!
Best,
Kamil

Hi, Kamil
Thanks for your response. So your suggestion is to just build a profile

Hi Panagiotis,
just a quick note, no matter what parameters and what software you will
changing
substantially, you run into the troubles, especially for BW photo.
youMy personal opinion - it is better to not compensate OBA in full. If
"omit" some amount of OBA, then your print will look more neutral under
illumination with a small portion of UV, and somewhat colder under
illumination with the standard portion of UV, which is probably more
acceptable for common viewers (my experience, not an absolute one and only
truth).

Hi!
I want to make with i1pro2 a printer profile for a paper full of OBAs.

the prints will be BW and are going to be seen under various lighting
conditions. What Argyll options should I use for building the profile?
Thanks in advance for any input.
