首都博物馆藏《编纸寿星》工艺及色彩分析

The Process and Color Analysis of Bianzhi Shouxing in Capital Museum

本文首先介绍了纸织画起源、工艺及题材。以首都博物馆藏清代《编纸寿星》为例对画面描述,并采用显微观察画面细节验证了纸织画的工艺,画面主要六种颜料用拉曼光谱和荧光光谱结合的分别到了主要成分,最后用高光谱成像仪发现一处隐含信息,在特征提取后的假彩色合成的增强影像中,寿星的嘴唇轮廓清晰可见,以上为图轴的鉴定、修复和保护提供重要依据。

This paper first introduces the origin,craft and subject matter of paper weaving.Taking the Qing Dynasty"BianZhi Shouxing"in the Capital Museum as an example,and using microscopic observation to see the details,we verify the technology of paper weaving,and the main six pigments were combined with Raman spectroscopy and XRF.Finally,a hiding messages was found with hyperspectral imager.In the enhanced image of false color synthesis after feature extraction,the lip profile of the birthday star is clearly visible.The above provides an important basis for the identification,repair and protection of the axis.
