This technique has resulted in the recovery of indented impressions on paper up to seven layers beneath the original writing, though findings may vary depending on pen pressure and paper thickness. While differentiation among inks can be accomplished by visual examination, nondestructive, and chemical tests, positive identification of the specific source of the ink (i.e., the exact pen) is unlikely. Another valued method used by forensic experts is called Video Spectral Analysis (or Comparator). Tools and Methods Document examiners of the 21st century use microscopy, chemistry, laboratory instrumentation and digital photography to uncover important clues. Historically, indented writing was identified and deciphered by means of low angle oblique light and photography. Although typewriters have largely fallen into disfavor with the advent of the computer age, forensic document examiners still may be called upon to investigate documents written on a typewriter. 1. a.

Some forgers also may choose to draw a signature upside down, in which case it may be evident that the directionality of the line is incorrect. Albert Sherman Osborn is considered the father of the science of questioned document examination in North America.. His seminal book Questioned Documents was first published in 1910 and later heavily revised as a second edition in 1929.
