When painting fingerprints with powders, the following general rules must be followed: - powders must be finely dispersed (dust-like); differ in color from the surface on which the fingerprints may be located; have good adhesion (sticking) to the fingerprints and do not paint the surface on which they are located; preserve the color and clarity of the fingerprint details on the fingerprint film; - it is advisable to first select the appropriate method of powder application and pre-paint the experimental traces on the same or similar surface; - powders must not be applied to a wet, dirty or sticky surface. It must be dried and cleaned of dirt. (To detect fingerprints on sticky surfaces, the use of powders is not recommended; iodine vapor or liquid chemical reagents should be used); - finer powders should be used on smooth surfaces, and coarser powders on rough surfaces; - if traces are not detected with one powder, another, stickier or heavier one, or a mixture of powders can be used.
