A latent print is not removable from a surface. What is lifted during the process?

In the context of latent print examination, the correct understanding focuses on the lifting process used to collect latent prints from various surfaces. When a latent print is developed using powders or other techniques, what is primarily lifted are the powder grains that adhere to the print.

During this process, special powders are used to visualize the latent fingerprint that consists of oils, moisture, and other residues from the fingers. These powders cling to the print, allowing the examiner to reveal the fingerprint pattern clearly. When an investigator lifts the print, they are transferring these powder grains, along with the unique formation of ridges that was previously invisible, onto a lifting medium such as tape or a card.

The reason the other options do not accurately represent what is lifted is that the latent image itself cannot be physically removed since it's essentially a representation of deposits left behind. Similarly, while oils and moisture are components of the latent print, they are not what is actively lifted; instead, it's the contrast created by the powder that allows for the print to be seen and collected. Lastly, the adhesive itself is part of the lifting medium and not a result of the print's transfer. Therefore, the act of lifting focuses on the powder grains that adhere to the print, which is why that
