When you get to CS2 for printing, you'll want to use the settings I
described below for ColorSync managed printing and for Photoshop CS2
managed printing. They're what Adobe recommends for the two different
types of printing workflow, as distinguished from the working
colorspace and editing environment.
I use the "North American Prepress 2" set in Edit->Color Settings to
establish my editing environment and color management policies. My
RAW files are processed to a [EMAIL PROTECTED] RGB rendering with either
Adobe RGB or ProPhoto RGB color profile, when I edit a ProPhoto RGB
image, I tell CS2 to use the embedded profile, not to convert to
Adobe RGB. I do not convert profiles or downsample to 8bit per
channel prior to printing: I let CS2 do the color management and
downsampling through the settings used in "Print with Preview" and
the Epson print driver dialog.
CS2's color management is more sophisticated and the settings options
much clearer than CS was. I'm not entirely sure what your current
ColorSync workflow is actually doing, but that's not really very
important as long as it's producing the results you are happy with!
