From the Paper:

"Surface conditions, color and texture all play a role in the determination that the technician makes as to which method of analysis would be most suitable. Fingerprints are of three varieties: visible, plastic and latent. Visible fingerprints are those in which the fingers are covered, for example with blood or paint touch a wall, door frame, or similar surface. Plastic fingerprints are those left in soft substances such as soap or putty. The most common are latent (invisible) prints, which can be detected by using powders, chemicals or lasers. (Conklin, Gardner, and Shortelle 2002: 112) There are numerous ways to retrieve fingerprints and depending on the situation, one method may be more successful than another."
