Title: RE: iMac G5 compared to 20" cinema display
Steve:
I would be very interested in finding out more
about how you did your testing and measurements. Hardware and software used and
a brief summery of your test protocol.
Also was this done on anything besides the ACD?
Your impression that this is an industry wide LCD issue and how might it also
impact CRT calibration frequency?
By sharing your protocol others might be able to
duplicate it with their displays and share those results.
The $64,000 question: Should users of specific
devices or maybe even ALL displays be calibrating much more frequently than we
all first thought?

We calibrate every 7 to 10 days because we
did a lengthy experiment on the ACD and the iMacs, comparing new monitor
measurement files daily to see what kind of drift was actually happening in
our environment. We saw no real drift in the display's calibration up to about
8-9 days where we began to see the Delta E rise. We are after as much accuracy
as possible in our softproofing workflows since expensive mag pages are on the
line. We'd rather be on the safe side. I've learned never to listen to
manufacturers reps and other expert prescriptions when it comes to color
management. Every shop has to find out their own "best practices" in their own
environment through diligent investigation and hands-on research.
