【 摘 要 】

As the internet becomes more popular, buyers send image files to manufacturers instead of sending swatches. However, this method may cause problems because different from the monitor between the buyer and the manufacturer, and also there is a problem depending on the light source. In order to overcome these problems, we investigated the relationship between color measurement values of dyed fabrics and RGB values of image files. The RGB values of image files tended to decrease with increasing dye concentration in all three colors. Correlation between RGB values and a∗, b∗values was observed at low concentration, but there was little correlation at high concentration. In the case of yellow color, there is no correlation between the L∗a∗b∗values obtained from the dyed fabric and RGB values obtained from the image file.
