AB  - Time-of-flight secondary ion mass spectrometry (ToF-SIMS) chemical mapping was 
      used to investigate the order of deposition of natural latent fingerprints and 
      laser printed ink on paper. This feasibility study shows that sodium, potassium 
      and C(3)H(5) positive ions were particularly abundant endogenous components of 
      the natural fingerprints and also present in the paper examined, but were mostly 
      absent in the laser printed ink. Mapping of these ions enables the observation of 
      friction ridges from latent prints on the ink surface, only when a fingerprint 
      was deposited above the layer of ink. As a demonstration of proof of concept, 
      blind testing of 21 samples from three donors resulted in a 100% success rate. 
      The sensitivity of this technique was investigated within this trial through the 
      examination of up to fifth depletion fingerprints and ageing of up to 28 days. 
      Migration of fingerprint and paper components to the ink surface, although 
      observed with increased ageing time, was not found to compromise determination of 
      the deposition sequence.
