Self-calibration method for color measurement of textile fabrics based on spectrophotometry
The assessment of color and color difference in textiles is a crucial aspect of textile inspection.Traditional manual com-parison methods are inefficient and susceptible to subjective factors.Instrumental color measurement methods,although limited in widespread adoption due to insufficient evaluation of accuracy and stability,present an opportunity for improvement.In this study,a self-calibration color measurement method based on spectrophotometry is proposed.The method enhances traditional spectropho-tometers by utilizing dedicated software to control the movement of the sample platform for a one-measurement-one-calibration approach.After acquiring the reflectance spectral data through a spectrophotometric sensor,the method automatically calculates the tristimulus values X,Y,Z for textile color.Three sets of fabric samples with different structures and color characteristics were mea-sured successively to analyze the accuracy,repeatability,and stability of the color data obtained by this method.The results indicate that the self-calibration color measurement method based on spectrophotometry provides accurate results,high data stability,good repeatability,rapid instrument calibration,strong resistance to environmental changes,and is suitable for measuring color and color difference in textile fabrics.
