Calibrating a iMac Screen

[rob-nikon]

I've finally taken the plunge and picked up a X-Rite i1Display Pro screen calibrator. I had a try earlier and it took a few calibrations to get something that didn't seem to have any colour cast. The first few attempts seemed to get a greenish cast. I set up the room in the conditions I would normally edit in (curtains drawn and light on).

I was wondering if there was any guides that anyone could recommend to getting it right.

Make sure your screen has been on for at least 30 minutes.
Set your gamma at 2.2 if your output is mainly digital, and 1.8 if mainly print
Set your luminance to 100 cd/m2
Colour temperature of 6500K if mainly digital output but if mainly printing then 5000K

Thanks that's really useful, I will try these settings.

I've used the X-Rite calibrator for a number of years now on several Mac's and it works fine. First I'd suggest you make sure that the ambient light is not to high as this may affect the calibration. You need to set the illumination to a level that matches your environment ( posh word for room) . Mines 120 cd/m2 yours may be different. If you notice prints are too bright then increase it, too dark then reduce it. It varies from location to location. Gamma settings 2.2 . gamma 1.8 is a very old repro setting that is largely redundant so stick to 2.2. Colour Temp 6500°K. Opt initially for the medium size target . My iMac calibrates well on the large target but the medium size one is quicker. Opt for letting the calibrator set the luminance, its easier. Review the results and see how close it gets. Don't worry if its a hundred or so ° K off or the luminance is a few cd/m2 out

also make sure the calibrator is well seated on the screen so there is no light leak. Tilting the screen a little helps.

Or press lightly and hold it firmly against the screen whilst it is calibrating.
