Fingerprinting Reference Pad

Never rub your forehead again! Originally created for use in our own
research and development laboratory, our latent print reference pads
create perfect, consistent test latent fingerprints again and again.
Before using any latent fingerprint development chemical, a test print
should be produced so that the validity and strength of the chemicals
can be determined before being used on actual evidence. In the past,
forensic scientists were forced to rely on the residues from their own
skin to produce the test prints. Depending on the individual and their
state during the day, these prints could vary by a tremendous amount.
Now you simply press your finger on the desired pad and the perfect
amount of latent print residue is left behind. Latent print development
techniques can then be accurately tested and gauged based on this
reference standard, regardless of who placed the print.

Chose Sebaceous Oil based or amino acid based latent prints.
