Color Target Comparator is used for both color and luminance measurring. In 1931, the CIE (Commission International De L’E’clairage) set up a series of visible spectrum color space standards. The basic CIE color space standards are CIE_XYZ. It is built on standard visual observers on the basis of ability to see, and it reflects the standards scope of color by eye. Based on CIE_XYZ there are CIE_XYY, CIE_Lab, CIE_Lch standard color space, etc. At present, the CIE lab color space is the most commonly used in the industry. In CIE Lab color space, L value stands for color brightness and a value stands for the Green-on-red value, and b value stands for the blue-on-yellow color value. If determine a value of color by only a group Lab, it will be not practical. However, we can determine the differences among them by comparing two groups of Lab values. Easy operation make you use it easily. Widely applied to quality control of plastic and printing industries’.
