Abstract: Objective To investigate the characteristic differences between the impressions of homologous laser-carving osmotic stamps in order to establish a method for the identification of this kind of stamp impressions. Method 9 homologous laser-carving osmotic stamps were manufactured and multiple impressions were imprinted. The characteristics of the impressions were analyzed with microscopes, Video Spectral Comparator, and other instruments. Results The detailed characteristic differences of homologous laser-carving osmotic stamp impressions were found out. Conclusion Although the specifications of homologous laser-carving osmotic stamp impressions agree well, they can still be discriminated. The identification should focuses on the comparison of detailed characteristics.

摘要：  目的寻找同源性机雕渗透印章印文间的特征差异，探索检验鉴定此类印章印文的方法。方法制作了9枚同源性机雕渗透印章并盖印大量的印文样本，通过文检仪、显微镜等仪器观察分析印文特征。结果找出了同源性机雕渗透印章印文间的细节特征差异。结论同源性机雕渗透印章虽规格性特征符合好，但仍旧可以区分，检验鉴定要以细节特征比对为主。
