摘要： 目的 现代高仿真伪造印章技术的发展给印章印文检验带来了前所未有的挑战。为了准确判断印文特征的性质，得出正确的鉴定意见，亟需了解不同伪造方法产生的印文特征。方法 利用Photoshop软件拓印不同图文内容的真实印文为印稿，利用光敏技术仿制光敏印章共20枚。分别将仿制的印章及印文与被拓印的印文进行比对，分析印文特征，并结合仿制过程分析特征成因及价值。结果 利用Photoshop软件拓印真实印文仿制的光敏印章印文与真实印文高度一致。鉴定存在较大的难度，但印文特征也会受拓印者技能、印章制作条件的影响产生差异。只要全面细致地进行比对，准确的综合评断，可以得出准确的鉴定意见。结论 利用Photoshop软件拓印真实印文仿制的光敏印章印文与真实印章印文的高度相似需要鉴定人仔细观察研究检材印文，熟悉印章伪造方法，了解印章印文特征，收集质量高、数量多的样本，全面细致地进行细节特征比对，以实现准确鉴定。

Abstract: Objective The development of modern highly imitated stamp technology has brought unprecedented challenges to forensic identification of stamp impression. In order to accurately determine the nature of stamp impression characteristics and draw correct conclusions, it is necessary to understand the impression characteristics generated by different forgery methods. Methods Using Photoshop software, 20 photosensitive stamps were imitated by rubbing real impression with different graphic and textual content. The characteristics, origin, as well as the value of counterfeiting photosensitive stamp and impression were analyzed by comparing impression of imitated stamp with the ones that have been rubbed during the imitation process. Results Our results showed that imitated photosensitive stamp impressions were highly consistent with real impression, leading to significant difficulties in identification. However, the characteristics of stamp and impression were also influenced by the skills of the forger and the conditions of making the stamp, resulting in slight difference. As long as comprehensive and meticulous comparison and evaluation were performed, the accurate and reliable opinions can also be obtained. Conclusion The high similarity between the counterfeiting photosensitive stamp impression by Photoshop software and real impression requires forensic experts to observe and study the questioned stamp impression carefully. By the means of collecting high-quality and large quantity known stamp impressions and conducting comprehensive and detailed feature comparisons, forensic experts could be familiar with the method of counterfeiting stamps and understand the characteristics of stamp impression，and thus accurate and reliable identification could be achieved.
