Question

Quizplus · Accepted Answer

The Video Spectral Comparator (VSC) is a specialized device used by forensic document examiners to compare and analyze documents, particularly for detecting alterations and counterfeits. The VSC uses different wavelengths of light to reveal features such as watermarks, fibers, inks, and other materials that are not visible under normal light. This technology allows examiners to identify the source of inks used, detect pen lifts, check for photo-substitution, and examine the document's integrity as a whole. Therefore, the VSC is the best choice for detecting irregularities on altered and counterfeit documents.
