All,
Thanks *very much* for the great feedback. I'm now confident that I'm
approaching this correctly, and I've learned some useful things about color
management. (I'm reading - and enjoying - Real World Color Management 2nd
Ed., but wonder if there are other resources where the nuts-and-bolts of the
workflow are clearly discussed?)
Dana,
The tabs I see in the Print dialog are:
Copies & Pages
Layout
Output Options
Scheduler
Paper Handling
ColorSync
Print Settings
Printer Color Management
Paper Configuration
Summary
The "Print Settings" and "Paper Configuration" tabs seem to belong to the
Epson driver, but I see no Epson logo. And yes, I selected Epson FireWire
when I added the printer.
Neil,
This may not mean anything, but the Summary tab only says "Profile: System
Default", not Generic RGB. Now that I know to ignore this, I'm okay. But
earlier I was wondering if this was related to the "Default Profiles"
preference of the ColorSync Utility. In my case, the RGB Default is set to
sRGB.
Steve,
You've presented one of the more succinct descriptions of the handoff from
Photoshop to the OS to the driver that I've ever read.
It sounds as though the color that Photoshop hands off is, in fact, in the
printer-paper-profile space. But the OS pretends it's in Generic RGB space,
but does nothing to the colors. When it gets handed off to the driver, the
driver also does nothing to the colors, since I've selected "Off (no color
adjustment)". The net result is that the correct colors get handed to the
printer.
Can anyone here contrast this with how PS CS color management works on
Windows?
Is anyone from Apple tuned-in here? Care to comment on what's been said so
far?
Best Regards,
-- Jim
