A: The completed fingerprint form must have all fingers rolled (two sets of 10 finger rolls) and two hand flats (two sets of four fingers taken together and two sets of flat thumb prints). Here is a sample of what the fingerprints should look like! If you are doing ink fingerprinting, the ink must be black ink. If you are doing digital fingerprinting, the fingerprints must be printed out onto a paper form. Both ink and digital fingerprint forms must have a signature of the officer who took your fingerprints and the stamp of the agency. If there is none, you will need to have your fingerprints notarized.
