Handwriting verification represents an important area in forensic science. Herein, handwritings based on different types and brands pen ink samples made in China were investigated by non-invasive micro-identification methods. Scanning electron microscopy and energy spectrum (SEM-ES) were employed to measure the micro elements and component analysis of the written traces, and spectral mapping (surface scanning) function was focused. The exact assessments of elements in handwriting traces can distinguish the microcosmic differences between different types and brands ink in handwriting, which provides a new means of analysis and research methods of pen handwriting detection in forensic science.
