印章印文阶段性特征在形成时间鉴定中的应用研究

Research on the Application of Stage Characteristics of Seal and Stamp in Formation Time Identification

印章从使用之初,由于使用方式、材料老化、使用环境等变化情况,会令其产生潜移默化的、不可逆的物理及化学变化,这些变化总会在不同时期反映在印章盖印的印文上。通过对印章印文的阶段性特征及变化规律进行研究,可以判断同一枚印章盖印的两枚或更多印文是否同一时期盖印的,即可以进行印章印文的形成时间鉴定工作。

From the beginning of use, due to unexpected situations such as usage, aging of materials, and usage environment, seals will produce subtle and irreversible physical and chemical changes, which will always be reflected in the stamp at different times.By studying the stage characteristics and changing rules of seal and stamp, it can be judged whether two or more stamps by the same seal were stamped at the same time, that is, it can help to identify the formation time of seal and stamps.
