Ken,
This was mentioned in an IDEAlliance webinar about the development of their
proofing certification.
It is also my personal experience that this helps.
You can check that yourself by placing the i1 on the display, calibrate it
(in emission mode) and measure the dark response (i.e. measure the emission
of a black paper (and not the monitor which can also change while heating);
you just remove the i1 from the display for the measurement. Replace the
monitor on the display, wait a few minutes and repeat. You will see that the
i1 response will drift. This is not surprising and is typical of any sensor
but by doing this you maximize the accuracy in the darker shades.

Roger, or anyone else,
Do you have a reference for this comment? I couldn't find in which
document
it was stated. Thanks!
Ken
It has been shown that, when the i1pro is left hung to the display for 15
to
30 minutes, before taking measurements, thermal drift issues with shadow
details are minimized. That's the technique used by IDEAlliance for
monitor
certification at RIT.
