I'm using CS1 at home, and I print only from that computer. As you guessed,
that explains the disparity. My work laptop runs CS2, so I looked. Yes, the
setup is different. I would think that choosing the working colorspace listed
as "ColorSyncRGB-Generic RGB" in CS2 would produce the same result. I'll
eventually find out. I also took a look at Print with Preview in CS2. It offers
different choices as well. I will have to experiment when I start using CS2 to
print. But I think the choice will either be "Let PhotoShop Determine Colors"
or "No Color Management." I notice that if I choose "No Color Management* in
CS2, the "Rendering Intent" menu goes grey, just as it does in CS1 when
"Source" is set to Document.
I realize my explanation was incomplete. I convert to Generic RGB colorspace
and 8-bit mode before printing. In the print box, I choose Premium Luster or
Velvet Fine Art, depending on which paper I'm using. For each of these I have
saved my printer settings as Advanced, 28,800. (They're might be more, but I'm
not on that computer now. ) I go to "Color Management" and make sure it's set
to ColorSync Workflow. I'm printing on an Epson 2200 by the way, which can come
very close to the 2400 in quality, although it's not as rugged or as good at
ink management. My next printer will be a 2400, but I probably will wait until
the 2200 gives up the ghost.
I'm saving this thread and will experiment with your method when I upgrade to
CS2. Thanks for all the info.
