An examination was done to investigate whether certain lifting techniques can lift recovered latent fingerprints on human skin surfaces of living subjects. For recovery Swedish Soot powder mixture (Swedish Black) was used. Donors intentionally placed fingerprints on the skin surface of living subjects. Finger marks were then in all cases recovered with Swedish Black powder. The procedure was repeated after 1 h and 4 h. Treated finger marks were secured and preserved as latent fingerprint evidence by different lifting processes. Having examined skin surfaces and finger marks we observed that the lifters such as white instant lifter, white fingerprint gelatin, black fingerprint gelatin, silicone, transparent adhesive tape, are suitable. Moreover, white fingerprint gelatin and white instant lifter proved to be very good at lifting treated finger marks. Black fingerprint gelatin was very good also, but finger marks were examined by slant light.
进行了一项检查，以调查某些提取技术是否能够提取活体受试者皮肤表面上恢复的潜在指纹。为了进行提取，使用了瑞典烟灰粉末混合物（瑞典黑粉）。捐赠者故意将指纹留在活体受试者的皮肤表面。然后在所有情况下都用瑞典黑粉恢复指纹痕迹。在1小时和4小时后重复该过程。通过不同的提取方法将处理过的指纹痕迹固定并保存为潜在指纹证据。在检查了皮肤表面和指纹痕迹后，我们观察到诸如白色即时提取器、白色指纹明胶、黑色指纹明胶、硅胶、透明胶带等提取工具是合适的。此外，白色指纹明胶和白色即时提取器在提取处理过的指纹痕迹方面表现非常出色。黑色指纹明胶也很好，但是通过斜光检查指纹痕迹。
