glazed coloured magazine paper surface. The porous sub-strates used in this work are carbon paper (writing and inked surface), matchbox, white paper, currency note and card-board. The prints were left for half an hour in the laboratory conditions at room temperature after deposition. The exper-iment was conducted in the mid of the months of February and March. The temperature and relative humidity during these months ranged from 10 to 25 C and 50.2% to
51.4%, respectively. The silica gel G powder (white in col-our) manufactured by Merck Specialties Private Limited was used to develop the latent fingerprints on all the differ-ent substrates. The ordinary brushing method was not used in this work.
