F+F ESDA 2

ESDA® 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 damages to fibers at the surface of a document, which have been created by abrasive interaction with overlying surfaces during the act of handwriting.

ESDA®2 features:

  • 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
