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.
Black Gellifters
The gelatin layer of these Gellifters features two special qualities: jet-black color and the high-gloss finish. The high-gloss provides for a reflection of light from the illumination source. Any light not reflected by the gelatin layer will be absorbed. Traces picked up by the Gellifter, however, will reflect the light in all directions. The end result is a high contrast between the lifted material and the gelatin layer. Black fingerprint powders, lifted with a black Gellifter yield images that are sharp and rich in contrast.
