The article presents new possibilities of revealing fingerprints on non-absorbent surfaces by using Wet Powder White, known and used in Polish dactyloscopy. Powder suspension based on titanium dioxide has been successfully used to reveal fingerprints on the adhesive sides of non-porous tapes, as well as on the inner surfaces of rubber gloves. So far, however, the broader application of Wet Powder White has not been known in Polish dactyloscopic practice. Foreign publications quoted in the article, research conducted and the use of white suspension powder in dactyloscopic opinions dedicated to the visualization of traces unequivocally confirm the high effectiveness of Wet Powder White in revealing fingerprints on non-absorbent surfaces, especially on plastic packaging and areas that have been or could have been previously wetted or subjected to high humidity.
