The quality of the prints produced by an ink jet printer is highly dependent on the characteristics of the dots produced by the ink jet pens. While some literature discusses metrics for the objective evaluation of print quality, few of the efforts have combined automated quality tests with subjective assessment. The authors develop an algorithm for analyzing printed dots and study the effect of the dot characteristics on perceived print alignment. The authors establish the perceptual preferences of human observers via a set of psychophysical experiments.
