Having spent many happy, ....(and frustrating), hours reading and
experimenting with colour printing
....and extensive "fiddling" with colour management, it seems to me that one
has to grasp a LOT of concepts, (relating to colour management), in order to
make a few simple settings in software, which result in predictable colour
print out ! i.e. the picture that comes out of the printer faithfully
matches what one was looking at on screen.
This consists of "profiling" ones monitor. i.e. Leave it switched on for an
hour,
and then run a utility to get brightness and gamma adjusted as accurately as
possible - and create a "monitor profile." This also becomes, (if chosen
during profiling), the Windows default monitor *.icm ...or was it *.icc
monitor profile.
Now !

looks very interesting, and I'm sure that whoever wrote it knows exactly
what they are talking about. This link obviously relates heavily to:-
http://www.normankoren.com/ deliberations on "colour management" and
"workflow."
There are some concepts here that seem, (to me at least), to be very
elusive. i.e.
In Adobe Photoshop there is a "working colour space." ...to which the
monitor colour profile is applied - solely for on-screen display of the
loaded picture, and according to ones current settings in Adobe, or actions
just prior to loading a picture, the current colour profile attached to the
picture is kept, (if there is already a profile attached to it), changed to
a different one of your choice, or removed.
The diagram "Colour management basics," (quite a way down that page), on
http://www.normankoren.com/color_management.html
seems to indicate that there should be one "translation," or "profile"
applied between the "working space" and printer but, what seems to be
happening whilst fiddling and test printing with my setup, is that profiles
are being applied twice ...somewhere, resulting in prints that are too dark.
!
It's all very well reading over all the concepts involved, over and over
again but, relating and applying those concepts in application software that
fully supports *.icc and *.icm profiles is VERY difficult !!!!
