Here's my situation...
After optimizing an image for print I "converted to profile" in
Photoshop 7.0.1 (Mac OS X.2).
The file is to be printed as a Lightjet 5000 from Calypso Imaging. The profile
I converted to is the custom LJ5000 profile downloaded from their
website. Calypso
suggests that it be converted with RI Perceptual. When I convert as
Perceptual,
it increases the saturation quite a bit. However, when I convert
with the RI as
Relative Colorimetric it does the same thing, only not nearly as
much (acceptable, ....
I guess).
I'm thinking it might be the limitations of my display that's the
problem. Although
my "Apple Studio 17" LCD" is calibrated with Spyder / OptiCal, I've heard from
various sources that this particular LCD display won't ever be truly accurate.
I'm not sure if I should go with what looks best on my monitor, or
go with Calypso's
suggestion and trust that their profile's doing it's job, but isn't
being accurately
previewed on my LCD.
Three things.
If you're making reflective prints on the Lightjet, its gamut isn't
significantly outside that of your display.
Rendering intent is very much an image-specific decision.
Until you've made the print, there's just no way to know whether the
soft-proofing side of the Lightjet profile is accurate.
If I were in your situation, I'd check my monitor profile against
some known reference (for example, a Macbeth Color Checker and a Lab
image of the Macbeth Color Checker), and if it's good, I'd make a
small test print on the Lightjet to verify the accuracy of the LJ
profile.
