Use of the Scanning Electron Microscope to Examine Fiber Impressions on Typewriter Correction Tape

CODEN: JFSCAS

Abstract

When a correction ribbon is used to correct a type-written document, fiber impressions from the paper are impressed upon the ribbon. Previous research used a comparison microscope to match fibers and fiber impressions between a correction ribbon and a document. However, because of inherent features of the correction ribbon system, several difficulties were encountered. Consequently, a scanning electron microscope (SEM) was used to alleviate some of the problems discovered by past research. The SEM, with its greater magnification power, detected both fibers and fiber impressions, creating a basis for association between a questioned document and a correction ribbon. Use of SEM also ameliorated the problems of past research and greatly enhanced points of comparison.
