 Visible prints are made when fingers touch a surface after toughing a colored substance like blood, ink, grease, paint, ect.  Plastic Prints  Are made when ridge impressions are left in soft surfaces like putty, wax, soap, dust, ect.

 On hard and non-absorbent surfaces  Ex. tile, mirrors, painted wood  Developed with powder  On Porous surfaces  Ex. Papers cardboard, and cloth  Devolved using chemicals

 RUVIS  Reflected Ultraviolet Imaging System  Used to locate latent prints  Powder  Used once prints are located  Comes in several colors, magnetic and non magnetic  Adheres to perspiration and oils in print  Can be photographed or collected with tape

 Super Glue fuming  Used on nonporous surfaces  Ex metals, electrical tape, leather and plastic  Fumes of super glue adhere to proteins in print and make a white visible print  Made of 99% cyanoacrylate ester, which is what makes the prints visible  Can be done in a fuming chamber or with a handheld wand  Iodine Fuming  Iodine crystals are heated and fumes combine with print to make them visible  Not permanent, will fade quickly

 Ninhydrin  Reacts with amino acids in prints to make a purple blue color  Physical Developer  Is a silver nitrate based reagent  Used when other techniques fail  Other chemicals used include those that cause the print to fluoresce under a laser or high intensity light source such as…  Quartz halogen, xenon arc, indium arc

 Small Objects  Transport entire object  Large objects  Photograph first  Allows print to be compared to digital database  Then lift with tape and place on labeled cards
