How should fingerprint ink be correctly applied?

From the base to the tip
From the top to the first joint
From the tip to ¼ inch below the first joint
At the center of the fingertip

The correct answer is: From the tip to ¼ inch below the first joint

The correct way to apply fingerprint ink is from the tip to a quarter inch below the first joint. This method ensures that all ridges of the fingerprint are adequately covered while avoiding over-inking, which can lead to smudging or loss of detail in the print. Inking from the tip allows for even coverage and collects the necessary ridge detail that is crucial for identification purposes. In contrast, applying ink from the base to the tip might not capture the necessary details at the tip and could lead to inadequate prints. Similarly, inking from the top to the first joint would essentially miss the crucial area of the fingertip where ridge patterns are most defined. Placing ink at the center of the fingertip does not provide the necessary coverage to ensure that the entire pattern is captured. Understanding the correct application technique is essential for law enforcement professionals, as accurate fingerprinting is vital in criminal identification and investigations.
