labor quality spectrophotometer (and we assume that the Display III device is properly characterized in the factory)

My guess is that up to now many of the cheap instruments are not so characterised - like IT8 charts they are just batch averaged. Stability is also important, so the nature of the filters comes into play. Graeme Gill.
