Which of the following actions could result in an improperly conducted fingerprinting process?

The action of allowing the fingers to slip or twist during the fingerprinting process can lead to an improperly conducted fingerprinting session because it directly affects the clarity and accuracy of the prints obtained. When fingers are not positioned correctly, or if they move during the recording, the resulting fingerprints may be smudged or distorted. This can hinder proper identification and potentially impact the decisions made based on those prints, including criminal investigations or background checks.

In contrast, using too little ink could potentially lead to faint prints, but it doesn't inherently disrupt the process of taking the prints themselves as long as the inking and pressure are managed correctly. The use of rubber gloves is appropriate and even recommended for hygiene and preventing contamination. Applying uniform pressure during inking helps ensure that the prints are clear and complete, which is a best practice in the fingerprinting process.
