Interactive errors in conventional CRT colorimetric prediction models

Up to now, almost all conventional CRT colorimetric prediction models are based on the `principle of tristimulus values superposition'. Whereas, by doing a series of experiments, we have found a fact that in CRTs there exists a kind of `interactive effect' among RGB channels, and this effect will invalidate above superposition principle and therefore result in a kind of `interactive error' in conventional CRT colorimetric prediction models. Our experimental results show that the errors caused by this `interactive effect' are often bigger than 10 units calculated with CIELUV error formulas.
