Perfect Print® ink pads, from Identicator®, can be used on any plain paper and produce sharp, black fingerprints. The hard, ceramic surface features micropores which allow ink to quickly rise to the surface of the pad and prevents worn or dry spots from forming on the pad over time. More importantly, however, the unique micropores in the ceramic surface regulate the flow of ink, preventing fingers from becoming overinked, resulting in unacceptable prints. Once ink is applied to the fingerprint card, it dries almost instantly, making it almost impossible to smudge or smear the fingerprint. Clean up is simple. Simply rub the fingers together or wipe clean with a cloth. No special hand cleaners are required. Best of all, the pads won't dry out over time, regardless if they are left open or unused. Available in four different sizes to accommodate any application. The large PI 30 pad features mounting brackets for adhering to a work surface.
