Although commonly overlooked, indented writing may be of significant value in resolving questioned document issues. As the term implies, indented writing is the non-visible indentations or images applied to a sheet of paper positioned below the page actually written upon.

The indentations may be made visible by rubbing with a crayon or the side of a pencil, however, it is a destructive process not used by forensic document examiners.

A specialized laboratory instrument is used by document examiners to recover indented writing. The process is non-destructive, leaving no marks on the document. An image is produced providing tangible evidence of the continuity, or non-continuity, of entries made in a journal, medical record, accounting book, etc.

A qualified document examiner will have the instrumentation and knowledge of techniques appropriate to a variety of document issues.
