What is impossible to achieve during the analysis of friction ridge prints?

During the analysis of friction ridge prints, it is indeed impossible to describe all discrepancies. This is because fingerprints are complex and can vary significantly due to various factors such as pressure, surface, and skin condition. A wide range of discrepancies may arise between different prints, and it is often not feasible to identify and describe every single one due to the intricate and nuanced nature of these discrepancies.

Analysis requires careful consideration of the features present in the prints, and while some discrepancies can be noted and described, fully documenting every possible variation is impractical. This understanding emphasizes the need for characteristics and features that are most relevant for identification, rather than attempting to enumerate every difference, which could lead to overwhelming and unmanageable amounts of information.

In contrast, the other options describe scenarios that can be achieved in the context of friction ridge analysis. Creating an exact copy, identifying every fingerprint, and matching prints without context are all situations that can occur but are not practical or efficient in real-world forensic analysis. However, the inherent limitations in fully detailing all discrepancies highlight the challenges forensic experts face in the fingerprint analysis process.
