The most commonly used technique is to take a brush and light/dark powder depending on the surface and dusting the print, then using special sticky tape to take the the powder that has shaped to the fingerprint
The fingerprint Analyzer will attempt to match it with another one in the FBI’s IAFIS (Integrated Automated Fingerprint Identification System).
Fingerprint dusting works because it sticks to the oil in the print. The sticky tape is used to lift the oil and dust.
