INFLUENCE OF THE ACCURACY AND PRECISION OF A REFLECTANCE SPECTRUM MEASUREMENT ON COLORIMETRIC VALUES

摘要

In this work the influence of the accuracy and precision of handheld spectrophotometers on the outcome of the colorimetric measurement is shown. Five different spectrophotometers where evaluated in terms of the accuracy and precision. Statistically evaluated data was used to caluculate CIE L*a*b* values and colorimetric difference. The results show thai the lower quality of the device may lead to inconsistency when measuring color difference.
