It may be possible to answer the question of whether or not a document was signed in blank, or after typing, by a microscopic examination of the line intersections. By removing the typewriter carbon at the point of the intersection, it can be clearly seen whether there is ink under the carbon or if the ink was removed with the carbon. A technique for determining the sequence of typewriting and most types of inked entries was developed. The results may be recorded photographically and subsequently used as a demonstrative exhibit in presenting the evidence during trial.
