What key advantage does the use of lasers provide in developing latent prints?

The use of lasers in developing latent prints provides the key advantage of improved image clarity. Lasers can enhance the visualization of latent prints by illuminating the ridges with high precision and contrast, making them easier to see and capture, especially on difficult surfaces. The focused nature of laser light minimizes background noise, allowing for the distinct features of the print to be more readily identifiable. This increased clarity is crucial for accurate analysis and comparison during forensic investigations, enhancing the quality of evidence collected.

While elements like cost, processing time, and chemical stability are important in the overall context of latent print development, they are not as directly related to the primary benefit of utilizing lasers. The specific enhancement of image clarity directly impacts the effectiveness of the latent print recovery process.
