A Raman Spectral Area Scanning Method to Identify the Sequences of Crossed Writings and Seal Stamps

June 01, 2023

Determining the printing sequences of crossed writings and seal stamps is often difficult because the most common methods used are expensive, time-consuming, and cumbersome. A new method using Raman spectral area scanning offers a better alternative while conducting pigment analysis and determining intersection sequences of writings and seal stamps. We explain why.
