Pre-Fingerprint Conditioning
Whether an applicant is being fingerprinted using ink or electronically, proper pre conditioning of the fingers, allows the best possible fingerprint images. It can also improve image quality for hard to capture subjects. In order to maximize the fingerprint resolution and minimize the chance of rejection, we recommend the following:
Do not use any hand lotion the day of being fingerprinted.
Clean both hands thoroughly of all dirt, debris or any potential residue before capturing prints. This helps to ensure the best possible image quality.
For some applicants, cleaning with soap and water may dry the hands, which may cause them to need additional conditioning.
Our technician will take a sample print on matted paper to inspect the rolled impression for proper minutia and print quality. If they determine additional conditioning is needed they may recommend the following:
Wypall Waterless Hand Wipes
Wypall Waterless are a pre-saturated cleaner used for which do not contain alcohol. They contain natural solvents which clean, grease, and and oil from fingers and at the same time moisturizing the skin on fingertips for fingerprinting. The skin surface feels “tacky” creating the optimum conditions for fingerprinting.
EZ Scan may also be used to restore desiccated, mummified fingers on cadavers. In cases where finger tips are dehydrated, one or two applications of EZ Scan will restore the ridges enough to permit gaining legible prints. Mummified fingers can be soaked in EZ Scan solution to restore ridge detail. Once complete, fingers can be processed through casting or conventional cadaver fingerprint taking methods.
Rub hands and fingers together for 3 seconds. Be sure to moisturize all skin surfaces being captured. The surface should feel “sweaty” (not wet) however the surface should not drip. Roll or capture the prints.
