I have an Epson Perfection 1660 Photo scanner. I use Monaco Optix to build
calibration profiles for my monitor, printer (Epson R800) and the scanner.
I am using Windows XP and know which folder to put the profiles into. I know
when to tell PSCS2 to use the printer/paper profile and how to tell my video
driver (ATI card) to load the proper monitor profile.
However I am not sure if I have to tell either PSCS or the Epson Twain
driver about the scanner profile or do they pick up that information
automatically. I wrote an e-mail to Epson support, but the response only
refered to the printer profiles.
Any help would be appreciated.
Thanks, Steve

So you are scanning via Twain directly into Photoshop? I can't help
you with that flow, but here's the flow suggested in "Real World Color
Management" by Fraser etc when you're scanning separately and then
opening the file in Photoshop ... he says to scan with the exact same
settings used when you generated the profile (or the profile becomes
meaningless) but don't assign anything, then when you open the file in
Photoshop you should get a "missing profile" dialog box (unless you
changed the Preferences warnings) ... at that point you should choose
"assign profile" and select the scanner profile and also check "and
then convert document to working RGB". The idea is that the scanner
profile has the correct colors but you don't want to edit in a device
specific space for various reasons so you then convert it to your
working space for edits.

You can see the profile assigned to the file easily enough, either in
File Browser or by doing Image > Mode > Convert to Profile and seeing
what the 'source space' is or by changing the bottom status bar to show
'document profile' (and probably several other ways as well).

With the Monaco system the important thing is to turn off any color
management in the Epson scan driver when scanning your target/print. Early
Epson scan drivers, and your scanner is a bit long in the computer tooth,
did not even have a choice of what color space to use. If you do not see a
tab where there is a choice of color spaces to use then there is nothing to
worry about.
Anyway, if you are satisfied with the results you are getting with the
custom profiles you generate you are probably doing it right. Monaco answers
questions posted to their support service very promptly and you may want to
contact them.
I would recommend it highly to people looking for a well rounded color
management system. I replaced the original Spyder monitor calibration device
with the monaco system mostly to try to get better color matching out of a
Canon printer. The problems I have are not with Monaco but with Canon and
their lousy, lousy printer drivers and color management protocols.
The canned profiles Epson includes for use with a color managed system are
so good that I do not see much difference in prints made using the custom
profiles I generate with the Monaco system. The Canon prints are much better
using the Monaco profiles but not as accurate as the Epson prints using the
canned Epson profiles. Therefore I conclude that serious printers should
avoid Canon like the plague: I am sticking with Epson until Canon can prove
they have people who can write software drivers.
