More recently, an instrument known as an Electrostatic Detection Apparatus, or ESDA, is used to produce a visual image of the indented writing on transparency film. Investigators at the crime laboratory The color of a piece or pieces of paper may be compared against a white standard or through a side-by-side comparison. c. High f-stop And most paper and dandy roll manufacturers keep logs for these defects, which can provide a relative age of paper (link). The most commonly used EDD is the electrostatic detection apparatus (ESDA), which uses an electrostatic charge and toner to visualize areas of indented writing that may have been left by erasures or pressure from writing on top of the document in question. Quick history: They were first used in 1848. Watermark is a distinctive form of image, shape, text, or any design that appears translucent and fainter when light passes through it.

Disguised writing is distorted writing that is intended to mislead the reader or forensic examiner as to authorship, and is often present in questioned documents.
