Greetings,
I have noticed that the illuminate and angle for my i1 and DTP41 are
D50 and 2 degrees. I am guessing they are set the same so their
readings will be close.
The settings on the production floor's spectrophotometers
(DataColor) are D65, 2 degrees for our local plant and D50 10
degrees for our corporate plant.
Readings for the same PMs color (186) on the local production floor
spectrophotometer is different than the reading for the same color on
the corporate spectophotometer. I would imagine is because their
illuminate and angles are different(?). Does the illuminate and angle
make a difference, unless one is trying to standardize device readings?
Thanks to all that respond.
-Bill-
