制作了 13枚“同版”渗透型印章和激光雕刻印章 ,分析了这些“同版”印章的印面特征和盖印印文特征。研究发现 ,相同条件下制作的“同版”印章的个体差异十分微小 ,如果考虑到各种盖印条件下 ,这些印章盖印印文特征的变化范围 ,“同版”印章印文的检验是十分困难的 ,甚至是不可能的。 Thirteen “Same Version” infiltrated seals and laser engraved seals were produced, and the characteristics of the stamps printed on these “same editions” stamps and the characteristics of the stamps and seals were analyzed.
