Background: In recent time, there are many different methods which are used in developing of the latent fingerprints. From all the methods which are used, powder and ninhydrin are one of the most preferred methods in the field of the forensic science because of their simplicity and effectiveness. They are more efficient in the dry, relatively smooth and non- adhesive surfaces. This paper elucidation the application of non-conventional powder for developing and visualization of latent fingerprints. In this, 5 different type of substrate is chosen. The study makes evaluation on the cheap and easily available powders which are effortlessly available in every Indian household. Result: The results obtained from this research are about 80% clear ridge details were seen on the different substrate like rice flour, potato powder, gram flour, Rasna and onion powder but only about 50% – 60% ridge details were seen in the case of the coffee, mint powder and tomato powder. Conclusion: Present study is an attempt to decipher the latent fingerprints with the help of non conventional methods. From the above used powder; rice flour, potato powder, Rasna and onion powder showed the better ridge details as compared to the other non conventional powder used.
