The application of aluminium powder is the most common method of developing latent prints. However prints on soft and porous surfaces, such as cloth, may require some kind of chemical treatment. The chemical reacts with the amines and produces a chemical called ruhemann’s purple, which, as the name implies, is a bright purple colored substance (grady, 2006).
