Calibrating Apple's 23" Display

A few weeks ago, I started working with this monitor, and the color is not matching our finely tuned Kodak Approval XP-4. The only calibration tool I have is the system calibrator in Mac OSX. I calibrate, by eye, then profile it using EyeOne Display. The results are consistent, but they’re off. I have profiles of the XP-4 that I use in PSCS, and when I switch to “proof colors”, the color changes, but it doesn’t get any closer to the proof. From what I’ve read and heard, this is a very good monitor for doing color. SWOP certifiable. What am I missing?

The Eye-One calibration will override any manual one you did before so you don’t need the extra (by eye) calibration.

your lighting may be way off. I would recommend reading our ColorNews newsletter issue #2 (and perhaps issue #1) as I talk about matching your lighting white point to your display white point (or vice versa) in order to get decent screen-to-print matches.

screen-to-print matching is actually one of the hardest things to do in color management - even though it is something we all try at some time or another…

So, I wandered over to Gretag’s website, looking for some support, and I stumbled into version 3.1 of their “eye share” software (measurement tool). Imagine my surprise, since I’m still using version 2.0.1. Well, what a difference a version makes! The new version uses luminance AND updates the video card (I’m not sure, but I don’t think the older version updated the card - I think it was pretty much just taking a picture of the state of the monitor). It is much closer now. I think if I get the display white point close to the ambient lighting - like you said, It might just dial right in.

Thanks for your insight - I’ll keep you posted
