The conditions under which latent fingerprints are deposited affect the process of development that can be used to effectively recover these marks. The conditions which can play a part include environmental conditions, the type of surface on which latents are deposited, the ability of the donor to deposit fingerprints, contact time, force of contact with the object etc. Very little previous work is available in the scientific literature addressing these conditions and therefore, an attempt has been made in this present study to assess the effect of some of these criteria and their effect on the ability of ninhydrin to develop the marks. Latent fingerprints from good and bad donors were obtained on paper with variable pressure under controlled conditions. Laboratory prepared 1% ninhydrin solution was used to visualise the prints.
