Possibly. Both are "generic" profiles. The only want to know for sure which
describes your printing process better would be to run a test of the same
image (originally in RGB of course) through both profiles and see which you
prefer. You have to decide if you want to do the conversions with the Imacon
profiles in ColorFlex or do the conversion in Photoshop. To be perfectly
fair, you'd do both in Photoshop using the same CMM and rending intent
although you could also try both profiles in ColorFlex as well.
I prefer to do all my conversions in Photoshop although I'll be the very
first to admit I don't do any production work so time isn't an issue. But I
prefer Photoshop because I have a really good soft proof , can see the
effect of the rendering intent before I make up my mind and have control
over black point compensation and can use the Adobe CMM.

There really is no "best" rendering intent since this is something that can
be image dependant. At least in Photoshop 6 you can preview the effect of
using Perceptual verses Relative. If you had to hold a gun to my head and
force me to use just one intent, I guess I'd have to pick Perceptual for
images but there are cases where a Relative intent will produce better
resutls.
In the beginning of the first quarter of 2001, you'll see a Photoshop add-on
that does pick the rendering intent (Perceptual verses Relative) using a
"smart" algorithm which can figure out based on the individual image which
would produce a better conversion. It's a product that will do batch
processing of many functions so it will automatically pick the rendering
intent with no user intervention. VERY cool and useful. That's about all I
can see under NDA.
