Latent fingermark being imperceptible to the unaided eye is the decisive form of physical evidence found on divergent surfaces at the scene of crime. It is decisive because of its perpetuality and uniqueness. The word ‘fingerprint’ is common in commonality but individual to a person. When a person grasp something, he left the traces of residues (secretions of glands) conforming impression of the ridges of the fingers. The fingermark residue is a complex matrix of secretions and xeno-materials. Thus demanding some means for their development and visualization based on their chemical and physical properties. Different techniques are functional to develop and visualize the latent fingermarks. The choice of application method for development process
