Just in case anyone else wants to follow up on Kevin's leads:
Gutenprint is at http://gutenprint.sourceforge.net/
Argyll is at http://web.access.net.au/argyll/argyllcms.html
for which you'll need Jam at http://www.perforce.com/jam/jam.html
Photoprint is at http://www.blackfiveservices.co.uk/photoprint.shtml
Gutenprint should build using the BLFS instructions for gimp-print (but
I haven't tried it yet).
Argyll is a real pig to compile as it uses jam instead of make. Tips:
unzip the source package into a sandbox directory. Edit the file
makeall.ksh to add '-f <path-to>Jambase' to the jam command. Make sure
you have a symlink between /usr/X11/lib and /usr/X11R6/lib. There may
be other ways of doing all this, but I didn't have time to research
'nice' solutions and I'm not prepared to become a jam expert for one
Basically, Argyll can generate a test print and then read back a scan of
a printout of it. This can then be turned into a profile for the
printer/ink/paper combo (it can do lots of other more scientific things too)
I'll try Photoprint when I've got round to gutenprint! Photoprint can
use ICC profiles.
Thanks Kevin - good tips!
