Hi Gerhard,
that's why I'm asking. The measurment spot of a X-Rite spectrometer is much
narrower than that of a X-Rite colorimenter.
So, I'm trying to get the same sample at the same spot (wide interpretation of
spot).
Best wishes
Andreas

E.g. for a correction matrix where there are two devices involved. As soon as I
move the devices on the screen I get obvioulsy different measurements. So, is a
correction matrix based on such "random" measurments a good representation? Or
is this simply too academically for practical usage where average people like
me don't see a difference in colors anyway?
In order to create an inter-instrument correction matrix you need corresponding
measurement pairs, where each color sample is presented to both instruments
(i.e both instruments need to "see" the same stimulus). If the screen is not
uniform, this can be only granted when both instruments measure a given RGB
sample at the same on-screen position.
