选择拉曼显微光谱法来分析和识别四幅 19 世纪手工着色石版画中的颜料，因为该技术与其他技术相比具有多种优势。无需任何采样即可进行完全无损分析的可能性可能是其对艺术分析最有利的品质之一。拉曼光谱还可用于测定一些FTIR无法检测到的颜料，如朱红、炭黑、镉颜料等。其中，样品中测定了普鲁士蓝、群青、炭黑、铬黄、赭石、红铅、氧化铁红、烧赭石、靛蓝、铬橙、酞菁绿和其他一些有机颜料。所获得的结果引发了人们对石版画年代的怀疑。
Raman micro-spectroscopy was chosen for analysis and identification of the pigments present in four nineteenth-century hand-coloured lithographs, as this technique has several advantages over others for this purpose. The possibility of performing completely non-destructive analysis without any sampling is probably one of its most favourable qualities for art analysis. Raman spectroscopy can also be used to determine some pigments that cannot be detected using FTIR, such as vermilion, carbon blacks, cadmium pigments, etc. Among others, Prussian blue, ultramarine blue, carbon black, chrome yellow, yellow ochre, red lead, red iron oxide, burnt Sienna, indigo blue, chrome orange, phthalocyanine green, and some other organic pigments, were determined in the specimens. The results obtained have led to doubts about the age of the lithographs.
