摘要： 目的 研究不同伪造方法制成的高仿光敏印章印文的典型特征，分析其具体成因，为高仿光敏印章印文鉴定提供依据。方法 制作同版印章，采用印面扫描仿制法、印文扫描仿制法制作高仿光敏印章，使用图像处理软件、超景深三维立体显微镜等观察比较高仿印章印文与真实印章印文的特征异同，总结高仿印章印文的固有特征及其与真实印章印文的高价值差异特征。结果 在不同的油墨量、打印分辨率、修版方式下，仿制的印章印文特征表现各异，但仿制形成的印章印文在图文质量、文字笔画细节特征、印文外部特征、点阵状漏白特征等方面表现特异、稳定。结论 研究表明，前述特征对于高仿光敏印章印文的鉴别具有重要价值，鉴定人在鉴定过程中应重点关注。

Abstract: Objective To study the typical characteristics of highly imitated photosensitive seal impressions and analyze the causes of these characteristics, thus providing reference for the identification of highly imitated photosensitive seal impressions in forensic practice. Methods Photosensitive seals of the same digital plate were prepared by scanning the surface of the original seal or the seal impressions. The differences between the real seal impressions and the highly imitated seal impressions were compared by image processing software and a super field depth three-dimensional stereo microscope. The inherent and valuable characteristics of imitated photosensitive seal impressions were analyzed. Results The characteristics of the imitated seal impressions were different from each other with different producing parameters, such as ink quantity, print resolution and image revision methods. But the characteristics of highly imitated photosensitive seal impressions were specific and stable on the pattern and text quality, stroke details, external characteristics and punctate leakage, etc. Conclusion These characteristics are valuable for the identification of highly imitated photosensitive seal impressions, which should be given more attention in forensic practice.

Key words: highly imitated photosensitive seal impression, typical characteristic, cause, identification
