Tenprint Fingerprint Certification Tenprint Fingerprint Quality Standards & Control 3

Question 1

What is the recommended approach when a subject has no fingers due to amputation?

Accepted Answer

Note 'Amputated' in each missing finger block and print all available fingers

Answer

Each amputated finger position must be annotated 'Amputated' (or 'XX' per agency standards) and all available fingers must still be printed.

Question 2

What is the primary purpose of quality assurance (QA) review in a tenprint fingerprint processing unit?

Accepted Answer

To verify that impressions meet minimum standards before submission to AFIS or FBI

Answer

QA review ensures each tenprint card meets image quality standards, reducing AFIS rejection rates and ensuring accurate identification.

Question 3

According to FBI EBTS, what must be done if a fingerprint impression is unclassifiable due to injury?

Accepted Answer

Mark the block with 'UP' (Unable to Print) and provide a reason

Answer

EBTS requires that unclassifiable finger positions be marked 'UP' (Unable to Print) with the reason documented on the tenprint card.

Question 4

What does 'edge sharpness' refer to in fingerprint image quality assessment?

Accepted Answer

The clarity of the transition between ridges and furrows

Answer

Edge sharpness measures how clearly ridge edges transition into furrows, which is critical for accurate minutiae detection.

Question 5

Which condition causes ridges in a fingerprint impression to appear with 'holiday' gaps or breaks?

Accepted Answer

Insufficient ink or excessive pressure causing ridge splitting

Answer

Insufficient ink or uneven pressure can cause gaps (holidays) in ridge continuity, making ridge endings appear where none exist.
