Ninhydrin is one of the easiest and most effective methods for developing latent prints on paper. Many latent print examiners use Ninhydrin exclusively on paper because of its effectiveness and/or their lack of a proper setup for DFO. Ninhydrin should always be used in fume hood or with an appropriate filter mask.
