ABSTRACT:
A fingerprint inking apparatus, incorporating a self-contained supply of ink and a drive means that automatically produces a uniform film of ink of the correct thickness, on a thin elastic membrane, in preparation to the taking of rolled fingerprints. The membrane is supported on a compressible foam structure or between two rollers such that a downward pressure of the finger causes the membrane to form around the finger, thereby transferring the ink to the finger.
