Chemical tests are important in the examination of printing inks because they also allow examiners to provide an approximation of when the document was written. b. Bracketing The use of an IR imaging system may be useful in helping examiners to differentiate the original writing from the covering material as well. Unlike the traditional watermark, which uses wet paper, here a relatively drier paper is used. Thus, forensic document examiners may use magnification, usually 20-40X, to better identify pen lifts and breaks, which is more often found in simulated writing, as compared to natural writing. Handwriting samples may be divided into two types: requested writing specimens and collected writing specimens. b. the investigator's hands are free to carry out other tasks while recording the notes.
