OUR AIMS (ideal)
What I'm wanting in our design computer Labs is a ColorSync
configuration that would allow our students to be able to do basic
color management of their Lab monitors by using (and making) monitor
profiles with hardware calibrators such as the i1Display.
I'd sure like to see our computer Labs' ColorSync configuration allow
this outcome as a possibility. (Ideally with us technicians to be in
the support / technical backup where needed!)
If I understand you, you wish to facilitate (a) learning about
profiling/calibration and (b) doing other work that depends on an
accurate profile/calibration.
It seems to me that these two are going to conflict UNLESS you can
somehow enforce a no-calibration (profiling only) policy so that the
state of the displays doesn't change. But a no-calibration policy
itself conflicts with (a).
If calibration is allowed, people doing (b) MUST be educated and carry
out (a) before doing (b). Why? Because even if the previous user
calibrated, profiled and made the profile available, why should the
next user necessarily trust or agree with the work of the first (What
dope setup this idiotic white point!?!?)? And what if some ignorant
button-poking bloke used the computer after it was correctly profiled
and messed up the monitor state? There are just too many variables
that are undetectable and/or uncontrollable by the operating system
(ANY operating system) to achieve what you are after.
I see a couple options...
1. Teach students to NOT trust the state of a shared machine when they
sit down to work...profile before each session if you care about the
color. Then the whole issues of getting people to select the right
profile just goes away because they create their own profile each time.
2. Have a couple dedicated "profiling training" machines, and have the
rest of the machines controlled in a fascist manner with respect to
display calibration and profiling. Then the whole issues of getting
people to select the right profile just goes away because you can (with
a bit of hacking ) default to the correct lab administrator maintained
profile.
