Although I certainly would liked to have seen NetProfiler expanded to
support more instruments, I¹m skeptical that it would have had a meaningful
impact on true inter-instrument agreement between different model spectros
on anything other than the calibration cards. Its one thing to get a close
agreement between instruments of different makes/models on standard
tiles/cards, but another thing to get close agreement on real world
substrates. I did a bit on in house testing on our spectros (938s, 939s,
DTP-41, multiple i1s, Spectroscan, etc) and close agreement on one substrate
did not necessarily mean close agreement on another, presumably due to a
variety of factors (paper type, gloss, OB content, instrument configuration
(Illuminant, sensor, etc). Now I simply assume that if the substrate
changes, so to will the agreement of the instruments measuring them, and if
close agreement on a particular substrate is critical, I recommend identical
make/model/rev level, and a grain of salt.
