The colorimeter to be calibrated measures the display primaries to determine the measured coordinates. In 1931 the C.I.E. (International Committee on Illumination) adopted these data as the CIE color-matching functions and defined the CIE 1931 XYZ color space.

Sources Of Error In Colorimetric Analysis

These depend upon how close the detector/filter combinations are to their respective CIE color-matching functions. Spectronic 20) is more desirable than a colorimeter with only a limited number of available wavelengths. While precision is a measure of repeatability or reproducibility, accuracy is a measure of closeness to the true value.

Hence, significant errors may be encountered when measuring the primary colors of a display, or any mix of them. These may have either a single detector with sequentially applied filters or multiple detectors with filters. The wavelength should be one that is closest to the maximum absorbance of the sample. CORRECTION METHODS The demand for accuracy of display colors requires improvement in accuracy in the instruments used to measure them. Colourimetry Errors
