Fingermark is the most widely used biometric method for identifying an individual. Fingermarks found at crime scenes can be classified as patent, latent and plastic impressions [1]. Patent and plastic prints are noticeable to the human eye without any particular treatment where the contrast between the fingermark and its background is suffi-cient for viewing. On the other hand, latent fingermark is present but not visible without further processing. Therefore processing techniques have to be applied to render the fingermarks visible. To date, various
techniques have been introduced for fingermark development such as optical (e.g. ultraviolet, UV imaging), physical (e.g. powdering) as well as chemical methods. Powdering method has been widely used since the early 1900s [2] due to low cost, simplicity of design and it does
not require much expertise [3]. Powdering method is also suitable for detecting fingermark on the object of a crime scene that cannot be transported back to the laboratory [4].
