Indented writing on a document is the result of pressure from a writing instrument on a preceding page. Anonymous and threatening letters, altered documents, checks bearing traced signatures and other documents could contain indented writing.
EXPECTED RESULTS
Indented writing may be deciphered through side lighting or with the aid of laboratory equipment. Subsequent handwriting examinations are sometimes possible with deciphered indented writing.
SUBMITTER'S RESPONSIBILITIES
Any document suspected of containing indented writing should be submitted to SFC in a plastic envelope for examination. Every attempt should be made not to write on documents that are placed atop the questioned document.
