The IBM SELECTRIC Composer: Statistical Evaluation of Printing Alignment
by M. Prewarski
This paper describes the measurement and evaluation of print alignment for the SELECTRIC® Composer, and discusses the suitability of statistical techniques for achieving both. This paper deals extensively with techniques and procedures for collecting data; however, it is not intended to define a generalized method for statistical evaluation. Printing alignment is shown to be described objectively and precisely by the distribution of measured misalignment; misalignment is precisely defined.
