In industrial production, the appearance effect of the product is largely attributed to the effect of color, so one of the most important issues to ensure the quality of color products is to make the color appearance as consistent as possible with the standard color sample and reduce color difference, so as to The color difference detection technology of the product puts forward higher requirements.
Many factories rely on experienced technicians to determine the accuracy of the color, but in most cases, it is difficult to meet the requirements of industrial production only by manual visual inspection, mainly because this method is affected by lighting conditions, background brightness, materials, etc. Influenced by factors such as gloss, texture, size switch, and visual and psychological differences of color measuring personnel, lack of accuracy: even if the same person repeatedly judges or the average judgment of different personnel is used, the results will still have considerable dispersion and random errors.
Quantitatively assessing the quality of color reproduction products has become more and more complicated problems that everyone needs to solve!
