Peter,
if you're doing ICC profile conversions downstream at the RIP level, just add your
customer's CMYK profile to Onyx PosterShop's input ICC profiles folder (you said it's
already there), and chose that profile in PosterShop as your CMYK reference input profile
prior to printing, and print the CMYK file(s) to the RIP as is.
If you're doing ICC conversions at the application level as you suggested...Photoshop in
this case...then you can convert to your editing or working space in Photoshop, prior to
printing. You mentioned both Don Hutcheson's BestRGB and Adobe RGB 1998: one or the
other must be chosen in Photoshop as your working space and installed as PosterShop's RGB
reference input profile. The conversion from your chosen editing space will then be done
by the RIP to whatever output CMYK profile that you've chosen for any given media. Just
remember, you're converting from CMYK to a very broad-gamut RGB space, only to have it
re-mapped back to CMYK. This workflow works far better with images that remain RGB until
they get to the RIP. At least, that's how it's supposed to work.
If you've "dumbed down" PosterShop and run custom profile targets through it using a
third party CM profiling package to profile specific media, then you can chose "none" as
input profiles in PosterShop, and take advantage of Photoshop's soft proofing and
conversion in features, and send the converted file(s) through the still "dumbed-down"
RIP, using only its scaling, tiling, FM diffusion functions, etc. I've come top believe
this is the best workflow, now that most applications (except Quark) have good CM
capability.
