I just set up such scanner at my dad's linux box
He had bought another model of that series (3170). But anyway yours should be similar if not the same setup. I used:
-SuSE 9.0 (distro does not matter)
-Gimp 1.2
- a matching sane along with xscanimage (though now used)
-iscan package installed and linked as a gimp plugin, from epkowa: http://www.epkowa.co.jp/english/linux_e/index.html
-littlecms library from:
http://www.littlecms.com/
-gimp color management plugins from:
http://www.freecolormanagement.com/color/gimp.html
(do not give a damn for the "alpha" status) ... but make sure to copy all icc profiles into /usr/lib/color (hardcoded in main.c ... I guess you can name some files to: scanner.icm, printer.icm and display.icm (if you have according inputs) ... but I way able to install some scanner icm's under different names and was able to select them anyway
- grab some scanner drivers for Windows from the Epson site. The EXE Files are self extracting Zipe-Archives, so you can simple do an unzip .exe
- look for the *.ic_ files
- install msexpand (package mscompress) from your distro (or from here: ftp://ftp.penguin.cz/pub/users/mhi/mscompress
- then do an expand .ic_ and rename the result to
- alternative
+ if no *.ic_ files found, look for *.cab files
+ install cabextract from your distro (look here http://freshmeat.net/projects/cabextract/
+ look for *.icm file
- the file program should tell you that the icm-file is a:
# file Per317_r.icm
Per317_r.icm: Kodak Color Management System, ICC Profile
First I installed a icm for the scanner for prints mode and a seperate icm file for slides/negatives mode. Per317_r.icm for prints (r=reflective) and
Mine were Per317_t.icm (t=transparent) -- that made the most sense.
If you have access to a Windows Box or do run wine you can grab the following windows program (ran under wine pretty flawlessly):
iccinspect.exe from: http://www.littlecms.com/iphoto/inspect.htm (Open Source !)
This program enables you to closely examine the contents of the icm files. It prints shows all the stuff like vendor and color-space infos and whatnot :-)
Second I scanned a picture with the scanner and applied the input icm to the scan with using the gimp (There is a command line tool for non-gimp users).
Then I adjusted my monitors settings, resulting in my setting the color temperature to 9300K since that resembled the picture the best.
I tossed in the Windows own icm file "sRGB Color Space Profile.icm" that I found under C:\Windows\system\color (Windows 98) as sRGB.icm and monitor.icm into /usr/lib/color so I have some kind of setup.
If you do have a disk with the correct icm file on it, use that file instead. Only use sRGB.icm if you want to exchange files with others.
Third I send a icm file for my dads printer (an epson :-) ) to my dad and he just tossed it into /usr/lib/color (as root) and has not complained yet :-D
I keep on ignoring slight color glitches while working on the pictures since I beleive the correct colors will come out of the printer anyway ...

Re:Google is the answer, my brother
tkgamma - a monitor calibration util for XFree86. Of course you need to consider the monitor, scanner and printer when dealing with colour profiles. The site I linked to earlier does have nstructions for scanning negatives with Gimp, so it's not specific to printing.

Google is the answer, my brother
A 10 second bout of googling and I found The Gimp color manager which lets you use ICC color profiles. You'll find the relevant profiles on your Epson driver disk.

Re:I'm talking about ICC profiles.
Support is still in its early stages, but from what I hear it's useable.

Re:LaTeX
Well, I'm a knowledgeable professional. In fact, I could almost boast you'd be hard pressed to find someone with more knowledge and experience with Photoshop. I say this with pride and arrogance because frankly I can. (though I know, there's always someone better than you out there...).
You're right. Stinks that there are no color management or CMYK plugins for GIMP.
Now, having said this...The Gimp is "getting there". No, it doesn't have CMYK yet...yet. And it doesn't have color profiles, but those are in the works.Five seconds and a little googling go a long way. Many "problems" that are reported with opensource software (such as the difficulty of a Debian install) are just a lack of five minutes and some google.

Color management
Photoshop also supports color management through and through- GIMP never has out of the box and never will, because there's no such thing as color management under linux
Not true. Color management in Linux is in its infancy, but it's not nonexistent.
But Color Management is the reason I won't be switching to Gimp 2 anytime soon. Frankly, ANY photo editing software is useless without CM, and I doubt that the Color Manager Plug-in for The Gimp will be revamped any time soon to work with Gimp 2.
So until I see some serious effort to support Color Management by Gimp's developers, I'll be sticking to Photoshop and Gimp 1.2, thank you. And yes, I use both.

Re:Number of disks (was RE: Yay ...)
Well, this shouldn't be a redhat issue, 'cause the 1200 is supportet by the Sane epson backend (and support is really good, not to say great). So it's probably you who has not editedMy only real outstanding issues are suspend (which swsusp should cover if I can't get Toshiba's ACPI BIOS to cooperate) and scanner support.
Unforch, the latter was a problem in 7.3 as well, and I never did get it working. Worked fine in 7.2, IIRC. Epson Perfection 1200U Photo is the scanner model. I haven't really done any looking into the issue, though, just tried SANE and it couldn't find the scanner.
/etc/sane.d/epson.conf (or wherever it is on redhat systems) or your kernel that doesn't have usb scanner support or ... something I don't know.In short, I approve of 8.0. The new compiler tool chain, Python 2.2.1, Mozilla 1.0.1, GTK+/GNOME 2.0, etc. made upgrading an eazy decision for me.
I've been running limbo for a couple of days and gnome 2.0 there was not exactly stable (panel crashing every five minutes or so), same problem with gnome 2.0 on sourcemage. So... would you say that this might be better with psyche? -
Re:Printing, and then maybe fonts
Interesting links, but they still leave open the device profiling cost, and their web pages smack of amateurism. Have there been any comparisons between their print quality and the quality of commercial color management systems? The field is littered with color management systems that never produced consistently good prints, and lacking any comparative data I'm skeptical that these two amateur projects have beat the trend.
A Google search did not turn up comparative or review information on either project, except for this negative user review of Argyll. I did turn up this page of free color management links, but no feedback from publishers or designers on how well any of them work.

Quick link
A quick search for "Linux color management" on Google led me to this web page.
Like the original poster, it appears this person has yet to find a solution, and may be starting a project.
To those that question the need, it truly is there. I'm a graphic designer by trade, and it is a major issue. Macintosh users (such as myself) have plenty of CMS resources, but I have yet to hear of anything for Linux.
