THE LEADING ELECTROSTATIC IMAGING SYSTEM FOR DETECTING INDENTED WRITING
ESDA® works by creating an electrostatic image of indented writing, which is then visualised by the application of charge sensitive toners. The sensitive imaging process reacts to sites of microscopic damages to fibres at the surface of a document, which have been created by abrasive interaction with overlying surfaces during the act of handwriting.
