a Powder method followed by C stain method (colour difference between real and forged fingerprints observed). b C stain followed by powder method (no colour difference between real and forged fingerprints). c Ninhydrin followed by C stain (colour difference between real and forged fingerprints observed). d C stain followed by ninhydrin (background staining observed). e AgNO3 followed by C stain (destruction of fingerprints observed). f C stain followed by AgNO3 (colour difference between real and forged fingerprints observed). g Iodine fuming followed by C stain (colour difference between prints and background staining observed). h C stain followed by iodine fuming (colour difference between real and forged fingerprints observed)
