Print Quality Measurement: The Application of Instrumental Analysis to Graphic Arts

Instrumental analysis is a powerful tool when evaluation of print quality is desired. Traces of prints were obtained by scanning them with a microdensitometer equipped with a reflection reading head attachment. The ability of newsprint to produce a good print under specified printing conditions is evaluated by measuring the uniformity of the contrast between dots and backgrounds, as well as the uniformity of the dots. A method of evaluation for these scans is formulated and discussed. Conclusions and reccomendations are made
