纸张上薄膜拓印指纹检验研究

Study on identification of fingerprints transferred by plastic film to paper

目的研究薄膜拓印指纹的特征和检验方法。方法利用塑料薄膜在纸张上进行了120次指纹拓印实验,然后比较拓印指纹和正常捺印指纹。结果成功转印出较清晰的拓印指纹41枚,发现了纸张上拓印指纹的常见特征。结论通过特征分析可以对薄膜拓印指纹进行检验。

Objective To research the characteristics and identification of fingerprint transferred by plastic film. Method One hundred and twenty experiments of transferring fingerprints to paper with various plastic films were made. These fingerprints transferred were compared with ordinary fingerprints. Result There were forty-one legible fingerprints in experiments. The characteristics of fingerprints transferred were found. Conclusion The fingerprints transferred can be identified by means of discerning their characteristics.
