Using a measurement device with a light source that spectrally approximates D50 (like the X-rite Exact or the Barbieri SpectroPad) might be important to ensure that you get measurements that are meaningful for color management purposes.
Only somewhat tangential...it's not hard to build an high-quality spectroscope that you can stick a camera behind, especially at the spectral resolutions of interest to graphic arts (typically 10nm, 3nm at most). And it's not that big a deal to turn a spectroscope with a camera into a spectrograph, and it's also not a big deal to turn a spectrograph into a spectrometer, maybe even a spectroradiometer. You can calibrate it against an existing instrument such as an i1 Pro...you get an additional step away from the factory device's calibration, but that's not likely to be a problem for graphic arts work. The only real challenge is to make everything yourself and put it all together. For a shop that specializes in something like fabric, the homebrew route might be a good option to consider. b&
