Nikolay, thank you for your time and comprehensive answers.
Because of my low color management skills, there are few things that are
unclear to me:
A) should I do RIP software calibration first, then do Argyll calibration &
profiling procedure on top of "RIP calibrated/linearised
printer" or in reverse order - do preliminary calibration & profiling
procedure with Argyll on uncalibrated printer (with
calibration on RIP disabled)?
B) If i will go the "preliminary profile" route you've recommended, do i have
to do Argyll calibration with preliminary profile and
again with target/big profile? or may calibration stage be done once (with
128 patches per colorant)?
It seems that calibration & profiling is a feedback loop process...
C) From what you've written, i understand that Argyll does't provide the way to
calculate/estimate individual ink limits,
the only way to do it is in RIP software using special test chart?
This is RIP calibration section in software i'm using:

So general process should look like this?:
1. Calibration using RIP software - estimating ILs and curves (You've
recommended to not setting TIL)
2. Creating preliminary calibration & profiling with Argyll (with
overestimated/rough ink limits)
3. Estimating TIL and ILs with more accuracy from preliminary profile
5. Creating main calibration & profiling with Argyll (using preliminary profile
and estimated TIL, calibration curves)
