Two-dimensional dust shoeprints are often of very high resolution and contain unique features. Lifting these prints in the most effective method may contribute much to preserving these fine details. A research was conducted by experts from Israel and Switzerland to compare gelatin lifters and electrostatic lifters for lifting shoeprints. Several substrates were chosen, and on each material a set of dry dust shoeprints was made. A set of wet prints was made on paper as well. The shoeprints were approximately of the same quality, and the only variable was the nature of the material. On substrates indifferent to the method used, the preferable sequence was tested. Gelatin lifter was superior on most substrates and for wet prints. The superior sequence for using both methods is electrostatic lifting followed by gelatin lifter.
二维灰尘鞋印通常具有非常高的分辨率，并包含独特的特征。以最有效的方法提取这些鞋印可能对保留这些精细细节有很大帮助。以色列和瑞士的专家进行了一项研究，比较明胶提取器和静电提取器用于提取鞋印的效果。选择了几种基材，在每种材料上制作了一组干灰尘鞋印。还在纸上制作了一组湿鞋印。这些鞋印质量大致相同，唯一的变量是材料的性质。在对所使用方法无差异的基材上，测试了优选顺序。在大多数基材和湿鞋印提取方面，明胶提取器更具优势。两种方法的优选顺序是先进行静电提取，然后再用明胶提取器。
