Abstract: Colour reading has an important role in the study of natural colours on batik, because it is one of few methods in determining the quality of a dye performance in batik fabric. The commonly used method is using visible ultra violet spectrophotometer that requires substantial cost and complicated operation system. This study aims to determine the performance method comparison between visible ultra violet spectrophotometer and mathematical count from digital images as colour difference test method to evaluate the quality of batik's natural colours from Gambier extract. We have done sample dyeing from previous research and doing colour difference test by spectrophotometer. Then we take the sample picture by scanner and measure the L*a*b* values. We count the colour difference from L*a*b* values using mathematics equation. The L*a*b* and ΔΕ values from both method are compared by statistical t test and ANOVA test. From the results it was found that the colour difference value of both met hods differ significantly, but each method gave good performance to measure the colour difference. However, it should be noted that the RGB space model depends on the input, so the more accurate the digital image with the original sample, the value will be closer to the colour difference values of laboratory measurements.
