METHOD OF ANALYZING COLOR ALLOY USING REFLECTIVITY

摘要

The present invention relates to a method of analyzing the color of a color alloy to determine the color of an object to be measured. More specifically, the reflectivity of each wavelength with regard to the color of a color alloy based on the composition thereof is compared to that of the color of an object to be measured by using the fact that the color appears different depending on the composition of the alloy. The method may include: a step of loading the object to be measured and a standard object onto a specimen loading unit of a spectrophotometer; a step of making light radiated onto and reflected off the standard object and the object to be measured by using a light source of the spectrophotometer; a step in which a detecting unit of the spectrophotometer measures the reflectivity by the wavelength when the detecting unit changes the wavelength of the light which is radiated from the light source onto the object to be measured and the standard object; a step in which a calculating unit calculates a deviation value which is the absolute value of the difference between the measured reflectivity for each wavelength of the object to be measured and the standard object and calculates an averaged value of the deviations; a step of drawing an average deviation ratio of the reflectivity by dividing the averaged value by the reflectivity value of the standard object; and a step in which the calculating unit determines whether the two colors are identical by comparing the average deviation ratio with a pre-established reference value.
