Color Measurement on Metalized Substrates

45° spectrophotometers are designed to optimally measure the appearance of samples, which means that they take into consideration color as well as gloss and texture. However, if a glossy specimen is viewed using a 45° spectrophotometer, it will yield values that indicate it is darker and more saturated in color than a matte sample, even if the color in the two samples is equally pigmented (Fig. 3).
