Tenprint Fingerprint Certification Tenprint Fingerprint Collection & Analysis 3

Question 1

When taking plain impressions on a tenprint card, the fingers should be placed in what orientation?

Accepted Answer

Pressed simultaneously without rolling, fingertips pointing downward

Answer

Plain impressions are taken by pressing all four fingers simultaneously straight down without rolling, with fingertips angled toward the card.

Question 2

The Henry Classification System primarily organizes fingerprints based on which feature?

Accepted Answer

The presence and position of loops, whorls, and arches

Answer

The Henry system classifies fingerprints into a hierarchical formula based on the pattern types (loops, whorls, arches) found across all ten fingers.

Question 3

An 'enclosure' (or lake) minutia type is best described as:

Accepted Answer

A single ridge that splits and rejoins enclosing an oval space

Answer

An enclosure occurs when a ridge bifurcates and then reconverges, forming a closed oval or lake shape within the ridge flow.

Question 4

What is the correct action when a tenprint card's plain impression does not agree with the rolled impression for the same finger?

Accepted Answer

Note the discrepancy and retake the entire tenprint card

Answer

Disagreement between plain and rolled impressions signals a recording error; the entire card should be retaken to ensure accuracy and integrity.
