    Abstract

    The guidelines set forth by the International Fingerprint Research Group were used to plan and conduct the evaluation of a dry contact p-dimethylaminobenzaldehyde (DMAB) approach to the treatment of latent fingermark deposits on porous substrates. Extensive investigations into the development method and its subsequent use across a range of conditions and substrates showed that the dry contact DMAB method is not as sensitive as the recommended ninhydrin techniques. It was found that these guidelines provided a practicable framework for the implementation of method optimisation and comparison studies. Illumination in the form of a cheap LED light source was shown to be a promising alternative to the much more expensive Rofin Polilight®, especially in teaching or remote environments.
