Electronic Typewriter Grids
In order to determine if misalignments of typewritten characters or entire typewritten passages are present, forensic document examiners have long made use of glass and acetate grids. These grids come with varying spaces between their lines and are physically placed on top of the typewritten document to check the alignment characteristics of the typewriting. Computer technology allows for these grids to be created in any spacing desired and overlaid on an image that has been imported into the computer. The two primary advantages of this are the ability to create a grid with any line spacing that might be necessary and the relative ease with which the results can be displayed for others.
