It is possible to suild a profile with a different intent as the default, or
to change intent at time of use.

This is a fairly accurate description of what these two intents do to an
image...

I'd recommend spending a couple hundred bucks on a copy of ColorVision's
ProfilerCMYK software first, and experimenting with UCR, GCR, UCA, ink limits
and balck generation there; its the only low cost program offering such
features. If you find the scanner-read profiles are not accurate enough for
you, but you like the other features, then upgrading to their ProfilerPRO
will still be a fraction of the cost of the other packages you mention, and
builds top notch profiles. This is a much more affordable set of solutions
than anything else with good black controls. If you decide to blow the big
bucks, I'd lean towards ProfileMaker, or Monaco Profile.
