Improved Pen Alignment for Bidirectional Printing

摘要

The quality of the prints produced by an inkjet printer is highly dependent on the characteristics of the dots produced by the inkjet 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. We develop an algorithm for analyzing printed dots and study the effects of the dot characteristics on the perceived print alignment. We establish the perceptual preferences of human observers via a set of psychophysical experiments.
