Five polychrome prints representing famous painters, such as Albrecht Dürer, were analyzed using a non-destructive and non-invasive methodology as required by the artwork typology. The diagnostic strategy includes X-ray fluorescence (XRF), reflectance micro-infrared (microFTIR) and micro-Raman (microRaman) spectroscopy. These prints were realized with a la poupée method that involves application of the polychrome inks on a single copper plate, before the printing process. A broad range of compounds (i.e., cinnabar, red lead, white lead, umber earth, hydrated calcium sulfate, calcium carbonate, amorphous carbon, and Prussian blue) was employed as chalcographic inks, using linseed oil as a binding medium. Gamboge was identified in the delicate finishing brush touches realized in watercolor.
按照艺术品类型要求，使用非破坏性和非侵入性方法对五幅代表著名画家（如阿尔布雷希特·丢勒）的彩色版画进行了分析。诊断策略包括X射线荧光光谱法（XRF）、反射式显微红外光谱法（microFTIR）和显微拉曼光谱法（microRaman）。这些版画采用了一种“la poupée”方法制作，即在印刷过程之前，将彩色油墨涂抹在单个铜板上。使用亚麻籽油作为粘结介质，广泛的化合物（即朱砂、铅丹、铅白、棕土、水合硫酸钙、碳酸钙、无定形碳和普鲁士蓝）被用作铜版雕刻油墨。在水彩画细腻的修饰笔触中发现了藤黄。
