Investigation of Resolution for Group 4 Facsimile.

Abstract

The objective of this study is to analyze alternative resolution rates for Group 4 facsimile. Four test documents were scanned at five candidate resolutions and the results of all twenty scans were printed. One of the test charts (the Legibility Test Chart) was developed on this project and is designed to measure the legibility of a visual communication system. The legibility of various character fronts at alternative resolutions was mesured. In addition the compression ratio for the Modified Read Code for each of the 20 scans was measured.
