Bi- magnetic powder has the remarkable properties of appearing black when dusted on a light coloured surface and appearing silver when dusted on a dark coloured surface. The greatest advantage of using Bi- magnetic powder is that the lifted prints will be black when placed on a white backing card. This eliminates the bother of comparing latent prints with light coloured ridges on a black background against rolled prints with black ridges on a white background. It also means that only white latent print lift backing cards will be needed. There is no need for black latent print lift backing cards with Bi powder.
