When you use the supplied canned profiles, then it is then simple.
The supplied profiles and baselines are a mixture of limiting the density of
each of the CYMK inks to ensure the right amount of ink is used at 100%,
then ensuring that the request for a given percentage (or density value) for
each channel is known and adjusted.
Within the BEST rip, the total ink limit (TIL) is tested and set - this is
very important for paper and link combinations on an inkjet, particularly
when the TIL can be as low as 100% (max is 400%) and this should be set
BEFORE profiling, as most profiling software does not go below 200%
This is why the baseline is connected to the profiles for each and every
paper profile. BEST also set the TIL within the paper profile, so you do not
accidentally use the wrong TIL with the wrong profile when changing profiles
in the rip.
The printer linearization is really only needed to ensure that the values
measured before profiling (within the baseline) are correct. You can build a
printer linearization months after building the first baseline and profile,
without having to re-profile each time.
When building the paper profile, the TIL in the profiling software can be
set to 400%, but decisions on what black generation (ie GCR and UCR)
settings are to be used, with that particular paper and stock in that
printer (see my older posts on the 'dodgy black stiple'). You can then add
your custom built reference profile, with the correct GCR and UCR settings.
If you can do all this, and match the results that BEST provide with the
canned profiles, then you are 'not' an average designer, who this product is
targeting.
Don't get me wrong, I would love the mac version to do everything the pc
version does (and more) , as I can only see a fully featured mac product out
selling the pc version no ends . . .

These guys didn't keep it simple. All I want is a rip that takes a source
