摘要：

目的通过对光敏指模指印与捺印指印的比较研究,总结两种指印的成印特点差异,为准确鉴别指印形成方式提供依据,进而为识别指印真伪和准确判明案件事实提供证据。方法利用光敏印章制造原理和方法制作指纹印模,将复制出的指模指印与手指指纹捺印的指印进行比较,发现指模指印不同于捺印指印的纹线特征,进一步探讨这些特征的成因及鉴定价值。结果光敏指模指印由于制作工艺、印面结构、取油方式、盖印条件等多方面因素的影响,容易出现其独有的不同于捺印指印的印文特征。结论光敏指纹印模所形成指印特征有别于正常指印,通过仔细检验能够准确鉴别。

  • Objective To compare the fingerprint produced with its photosensitive mold against the real fingermark so as to discover the distinctions between the two kinds of fingerprint finished version, thereby building up a foundation for veracious identification into the way to give birth of fingerprint so that whether one fingerprint is real or artificial will be recognized and evidence is thus able to provide for the relating case to be judged on authenticity. Methods Based on the principle and method of photosensitive seal manufacturing, the fingerprint mold was made to produce its duplicated fingerprint finished version that was compared with the fingerprint resulted from the relevant real finger impressing onto a receiver, e.g., a piece of paper. It was revealed that the fingerprint produced with the photosensitive mold was different of the characteristic lines(loops and whorls) from those of the real fingerprint. Furthermore, the discussion was made into the difference of the revealed characteristic features about their cause of formation and identification value. Results The fingerprint produced with photosensitive mold is prone to engender the unique characteristics different from the real finger-pressed fingerprint due to its production process, the structure of the printed surface, the way to take oil, the seal impressing conditions and other factors. Conclusion The fingerprint characteristics resulted from the photosensitive mold are different from the real fingerprint, capable of being accurately identified through careful scrutiny and comparison.
