With the increasing demand for accuracy in color measurement across various industries, color difference has become one of the crucial indicators for product quality evaluation. Online spectrophotometers measure color in two aspects: the emitted color of screen light sources and the appearance color of products. By calculating the tristimulus values and other chromaticity parameters of the object color, they verify the discrepancy between the currently measured color and the target value. This effectively improves the efficiency of product quality inspection and reduces errors caused by human mistakes. They are commonly used for the precise measurement of the appearance color of industrial products.
