摘要
针对近年来新出现的基于数码拍摄的颜色测试技术,考察了数码测色法中具有代表性的Digieye数码测色系统的颜色色域问题。为研究其对不同类型纺织面料颜色评价的适用性,选取PantoneTPX纸质色卡、染色织物和交织混色织物作为测试比较对象,以Datacolor SF600分光光度测色系统作为测试对比仪器,分别对3种类型的18个色样进行了颜色测试。研究发现,校准后的DatacolorSF600分光光度测色系统和Digieye数码测色系统用于纸质色卡颜色测试时,能够获得较为一致的颜色评价(ΔE*00=0.79);但当它们用于非平整表面的染色织物颜色评价时,会出现一定的颜色差异(ΔE*00=2.19);用于交织混色织物的颜色评价时,色彩差异更大(ΔE*00=3.25)。视觉评判分析表明,Digieye数码测色系统虽然存在一定的色域缺陷,但其更符合视觉观察结果。
This paper investigates color gamut of Digieye digital color measuring system which is the most representative one in digital color measuring method in allusion to recent color measuring technique based on digital photography. To study its applicability for color evaluation of different types of fabrics, Pantone TPX paper color card, dyed fabrics and interwoven mixed color fabrics are selected as the comparison object of the test. Datacolor SF600 spectrophotometry color measuring system as the comparison testing apparatus is adopted to carry out color testing for 18 color examples of 3 types. The researches find out that calibrated Datacolor SF600 spectrophotometry color measuring system and Digi- eye digital color measuring system can obtain almost consistent color evaluation （△E＊00=0.79） during col- or testing with paper color card. But when they are used for color evaluation of colored fabrics with non- flat surface, certain color difference will appear （△E＊00=2.19）. When they are adopted to evaluate the color of interwoven mixed color fabrics, color difference becomes greater （△E＊00=3.25）. It is known from visual judgment and analysis that Digieye digital color measuring system more complies with visual observation results, though it has certain color gamut defect.
