Electrostatic Lifter | Gelatin Lifter

ABSTRACT

Two-dimensional dust shoe prints 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 shoe prints. Several substrates were chosen, and on each material a set of dry dust shoe prints was made. A set of wet prints was made on paper as well. The shoe prints 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.

Two dimensional dust shoe prints found at crime scenes are often of very high resolution and contain unique features. Thus, it is most desirable to lift these prints...
