Main uses: Latent fingerprints on non-porous and semi-porous surfaces.
Instant powders are, like the special powders, mixtures that diminish the risk of smearing prints. The difference between the instant and the special powders lies in the particle size of the diluant. With the instant powders, these particles are larger than those used in the special powders.
Therefore, the instant powders have even fewer "greasy" characteristics than the special powders and can be used on surfaces where the risk of smearing a print is especially large. The powder (instant silver, gold, and black) can be sprinkled generously over a surface from the brush, after which the powder particles are moved over the surface by tapping the object.
Instant black
Main uses: Latent fingerprints on non-porous and semi-porous surfaces.
Instant black can be sprinkled over a surface from the brush, after which the powder
particles are moved over the surface by tapping the object.
Main uses: Latent fingerprints on non-porous and semi-porous surfaces.
Very suitable for relatively clean and smooth non-porous surfaces such as glass, painted wood, steel furniture, hard plastic. Excellent contrast against dark surfaces and black gelatin lifters. This powder is suitable for most surfaces found at crime scenes that have to be processed for fingerprints.

Instant Gold provides better contrast against light-colored surfaces
than Instant Silver. However, it adheres more strongly on surfaces and
is therefore less suitable for routine use.
