What is the Type 4 Fingerprint Type?

• A. Rolled impressions are the ten fingerprint images rolled from nail to nail; plain impressions verify the sequence and accuracy
• B. Identification flat impressions are taken simultaneously without rolling
• C. Four-finger flat impressions collected in a single step
• D. Rolled impressions are the ten fingerprint images rolled from nail to nail; plain impressions are used to verify the sequence and accuracy of the rolled impressions

Answer: (D)

Type 4 captures both rolled ten-print impressions and plain impressions to verify the results. Rolled impressions involve rolling each finger from nail to nail to get full ridge detail for all ten fingers. Plain impressions are flat images taken to check that the rolled prints are in the correct order and that nothing is missing or misaligned. This combination ensures the prints are complete and accurate. The description that matches this approach states that the rolled impressions are the ten fingerprints rolled from nail to nail, and plain impressions are used to verify the sequence and accuracy of those rolled impressions. Descriptions that mention only flat impressions or only a partial set don’t reflect this paired approach.
