To study the performance of the three spectrophotometers: Spectroeye, i1, and eXact, the spectral reflectance of X-rite ColorChecker® was measured with them. By computing the standard deviation of spectral reflectance and color difference ΔE*ab, the stability and repeatability characteristics of the three color measuring instruments were analyzed. The results showed that the standard deviations of spectral reflectance are less than 0.001. The average color difference between the measurements and reference data is less than 2ΔE*ab. The color difference between each two spectrophotometers is about 1ΔE*ab. The measurement error between the spectrophotometer is acceptable, so we could choose corresponding instrument according to the range of measurement wavelength.
