Psychometric testing, in the form of paired sample comparisons, is used to determine tolerances on optical density and color registration settings on the IBM InfoColor 70 printer. In the process, several print quality metrics are evaluated and the data is analyzed in several ways to explore possibilities of conducting psychometric testing with small numbers of participants in conference room environments. Both are shown to be possible. Several conclusions are also drawn about metrics for optical density and color misregistration effects.
