An excerpt from the paper
Using a combination of panel evaluation and quantitative printed image analysis, a direct relationship between visual perception and paper quality control has been made. A specifically designed print target is used to measure the effects of ink jet print on paper. The system produces objective measurements of bleed, wicking, raggedness, dot gain and other parameters that have been used to statistically correlate with human panel evaluations. The automated image analysis techniques employed measure comparatively, provide a high level of reproducibility and are objective, requiring no operator inputs.
