Only two thing are necesary:
your RGB Profile (if you didn4t set up your supreme to use icc scanner
profile- ask your trainer how to do that - you can asume a generic profile,
maybe the working rgb color space that you already have in photoshop: RGB
ColorMatch, Adobe RGB (1998) ) and the destination CMYK profile (supplied by
your printshop).
It's bad enough to be in the claws of Scitex, but using a profile for
the scanner's RGB which has zip and zero to do with the scanner's RGB
as the source in an iQueue transformation is a recipe for disaster.
Profile the monitor and profile the scanner with ProfileMaker, hope
the scanner software will allow you to use the scanner controls with
the scanner profile the way Linocolor and Newcolor do, and if your
scanner software doesn't support ICC CMYK color spaces, then convert
to an ICC CMYK production space in iQueue.
If your scanner software only saves out Scitex CT, then it's only an
8 bit format for RGB and CMYK. And it doesn't support embedding of
ICC profiles nor does it support Lab. So in iQueue set up a queue
that converts Scitex CT to TIFF or JPEG (whichever suits your
workflow), assign your scanner profile as source and a Pshop RGB ICC
working space or ICC CMYK production space as destination.
