Perfect Print® ink disposible inking foils and strips are used for taking fingerprints using foil backed ink designed for single-use, the user simply peels the two halves of film apart and rolls the fingers on the two exposed surfaces. A fine, thin layer of jet-black fingerprint ink is transferred to the fingers. The fingers are then rolled on a standard fingerprint card, producing clean, sharp prints. These are ideal for on-site fingerprinting or when fingerprinting is not done on a regular basis.
