B. Wilshire et N. Hurley, DEVELOPMENT OF 2-DIMENSIONAL FOOTWEAR IMPRESSIONS USING MAGNETIC FLAKE POWDERS, Journal of forensic sciences, 41(4), 1996, pp. 678-680
Footwear impressions deposited on various types of surface were develo
ped using magnetic flake powder and several conventional dusting powde
rs. Although comparable results were achieved when glass was the recep
tor surface, the magnetic flake powder proved superior for revealing f
ootwear impressions on rough or porous surfaces such as linoleum, poly
thene and paper.
