北京一版帆船邮票印刷色料科技分析

Scientific and Technological Analyses of Printing Pigment of Beijing First Edition Sailboat Stamps

利用超景深三维视频显微镜、激光显微共聚焦拉曼光谱仪、扫描电镜-能谱仪对三枚民国时期北京一版帆船邮票印刷色料进行科技分析。结果表明,三枚邮票均为手工雕刻凹版印制,灰棕色邮票油墨中的色料是红丹和炭黑,桔黄色邮票为铬酸铅,草绿色邮票为铬酸铅和普鲁士蓝;纸张和油墨中的填料可能是高岭土、碳酸钙、氧化锌、二氧化硅等。研究表明,多技术联用在邮票印刷品分析中有较好的应用。

Scientific and technological analysis of the printing pigments of three Beijing first edition sailboat stamps during the Republic of China period.These methods include ultra-depth of field threedimensional video microscope,Raman spectrometer and scanning electron microscope-energy diapersive spectrometer.Results show that all three stamps were printed by hand-engraved intaglio.The coloring substance of the greenish-brown stamp is composed of red lead and carbon black.The orange stamp is lead chromate,and the grass green stamp are lead chromate and Prussian blue.Then,based on the detected elements,it is inferred that the auxiliary components of paper and ink may be kaolin,calcium carbonate,barium sulfate,silicon dioxide and so on.According to the theory of color subtractive method in printing chromatics,the coloring principle of greenish-brown and grass green ink is analyzed.This study have shown that multi-technology has a good application in the analysis of stamp prints.
