KlearInk™ Ceramic Fingerprint Taking Pads are made of a micro-pore space-age ceramic which allows the clear ink to rise to the surface through capillary action. A reservoir of ink underneath the pad allows for re-inking of the ceramic pad each time fingerprints are taken. Simply touch finger(s) evenly on the pad surface, excessive pressure is not necessary. Fingerprints will begin to develop within seconds. (KlearInk™ Pads require coated KlearInk™ Record cards and Labels.)
