ESDA Example
Move the slider to view the results of an ESDA examination. On an ESDA print, impressions appear dark grey on a light grey background. The photographs show impressions of practice forgeries made on a piece of paper whilst resting on the questioned document.
Signatures:
Handwriting :
The examination of writings to establish or eliminate common authorship, differentiation between genuine and forged handwritings, disguised writings etc.
On receipt of copies of the questioned document(s), advice can be given as to suitable comparison material which will invariably require the presentation of course of business signatures or handwritings, possibly in conjunction with specimen exemplars produced specifically for the examination.
ESDA:
The ESDA technique reveals writing impressions on documents which have been caused by one document having been written upon whilst physically resting on top of the document under examination. The writing process consequently may impart indented and/or electrostatic impressions in the underlying paper surface. These impressions are invisible to the naked eye but can be highlighted with this technique. ESDA can provide information as to the history/creation of a document, raise impressions of practice forgeries, raise indented tracing guidelines, associate documents one with the other, show that documents have been created en masse etc.
In order to preserve evidence for ESDA testing, once a document is identified as questioned, it should be stored correctly. The document should not be touched with bare hands – gloves should be worn for handling. The document should be held between two pieces of plain paper and submitted in a hard backed envelope. The envelope must be addressed before the document is placed inside.
