Hello Andrew: Thanks for the response. Regarding the software I'm using, it's the current version of X-Rite's i1Profiler (v. 1.5.6). Do you have suggestions for profiling software that might work better with the iMacs? Which software? That's critical. The offering from X-rite isn't best in
class but netiher are the two dispalys you're working with so yes, that might be as close as you get.
I was aiming for the 100 cd/m2 based on suggestions at http://www.imagescience.com.au/kb/questions/188/Calibrating%20Monitors%20Usi... and also because that seems to match the brightness we get using the viewing setup we have (Solux bulbs in clip-on lamps, not a viewing booth). Do you think it would be worthwhile to move the lights around to increase the light level? I may do that and also up the luminance target I'm aiming for.
the luminance to 100cd/m2
That might be too low for the units to natively hit that value. Depending on the display, it's age etc, that's a really low value to hit and may be part of your problem. Try 150cd/m2. You can try moving lower from there (although I don't know why you'd want such a low value).
The two machines in question sit side-by-side, so conditions are pretty close. I wondered about the possibility that someone has been messing about with the controls and have posted notes asking that everything be left as-is, but who knows whether the request is being heeded.
Other than the location, the two sets of displays, calibration, ambient lighting and print viewing conditions are identical? Sure the students are not adjusting the OSD controls?

Thanks for the link to the Luminous Landscape article. I'll see what I can do based on some of the suggestions. Bruce -- Bruce Bumbarger Library Conservator Magill Library - Haverford College 370 Lancaster Avenue Haverford, PA 19041 610-896-1165
