Thanks Stephane,
So technically this is possible but
file size will be too big and that's why there is no software that makes
such profile? (as well as there is no software that can make use out of
such profile)
Am I correct?
Is there a software that makes RGB output
profiles with 33 grid points in each table?
regards,

Since a A2B table has a grid size of "grid points
at the power of colorant
quantity), a A2B table for a CMYK profile with 33 grid points would require
1185921 table entries per intent, while the same thing for a RGB profile
only require 35937.
If you reduce the amount of points to 17 for a CMYK profile, you fall to
83521 entries...

Hello Terry,
Profiles are different output profiles (RGB and CMYK). RGB profiles are
from
EPSON, CANON. CMYK profiles are from Adobe (Euroscale coated) or ECI
(ISOcoated).
I made same own profiles with PrintOpen 5 and they as well have only 16
grid
points in A2B table, but 33 points in B2A!
I didn't see any profile yet with 33 grid points in A2B table! Why? May
be
this isn't technically possible?

Re: number of grid points in A2B table
I've just looked at one of my MonacoPROFILER profiles and it has 17 points
A2B and 33 points B2A. What sort of profiles are you lookng at?

Could someone please explain why in an output profile (be it an RGB or
CMYK)
there isn't more than 16 grid points in A2B table?
At least this is what I have observed so far...
