Unlike other lifting media, BVDA Gellifters have been especially developed for the lifting of fingerprints, shoeprints, dust marks and micro traces. The thick, non-aggressive, low-tack gelatin layer allows traces to be lifted from almost every surface, including porous material such as paper and cardboard. Lifted prints can be transported for photography or closer examination.
The gelatin layer of the white Gellifter absorbs blood and dyes from staining solutions. These traces can easily be copied onto the gelatin layer and then viewed free from a interfering background. The extreme white color of this Gellifter has a low fluorescence. Staining solutions which fluoresce when excited with green light (e.g., Hungarian Red) will therefore show up in high contrast to the gelatin layer. We advise that shoeprints in dust be lifted with the black Gellifters, even when lifting dark-colored prints that intuitively would seem to contrast better on white Gellifters. A clearer and better contrasting result is always obtained with a black Gellifter.
