ESDA® 2

The Industry Standard System for Detecting Indented Writing

The ESDA® 2 works by creating an electrostatic image of indented writing, which is then visualized by the application of charge-sensitive toners. The sensitive imaging process reacts to sites of microscopic damage to fibres at the surface of a document, which have been created by abrasive interaction with overlying surfaces during the act of handwriting.

  • Creation of permanent records
  • Repeatable without loss of information
  • Effective on old documents
  • A3-sized document bed
  • Original cascade development method
  • Improved toner pad development
  • Optional aerosol hood for ‘powder cloud’ development
  • Replaceable vacuum bed
