Dear #photographers & visual #artists running #Linux, what are your tricks for #colour -accurate #scanning photo prints on consumer-grade gear (not a film/drum scanner)?

I have 3+ #scanners, all with wildly different #color results, as you can see below. At least 2 of them can scan directly over LAN (in Simple Scan).

Ideally I'd want #colormanagement / calibration of scans, ideally with "Simple Scan" (otherwise, how do you do it with XSane?). I have a ColorMunki spectrophotometer, if it helps.

I use a target, the IT8 7/2 1993 from http://www.targets.coloraid.de/ , then calibration: http://www.argyllcms.com/doc/Scenarios.html#PS1 , after that you'll get an ICC profile. I then scan with a shortcut keyboard to a script (Win+S , setup in Plasma):

#!/bin/bash
version=$(date +%Y-%m-%d_%Hh%Mm%Ss)
output=$HOME/pictures/screenshots/${version}_scanner_raw.png
scanimage -p --device "genesys" -l 0 -t 0 -x 210 -y 297 --resolution 600 --calibration-file /home/<user>/pathToYour.icc --mode Color --format=png > ${output}

Silly as it may sound, you'll almost always get best results by photographing the print in raw on a camera you trust. If you must scan them on a flatbed though, I'd recommend using the tried-n-true #xsane, as it gives you the ability to adjust the image during scan/preview in far greater detail than many other scanner programs. It also gives you the option to use ICM/ICC Profiles.
