The purpose of this research is to determine the relationship between the solid ink density and image quality by application of an image quality scaling method. The results quantify the relationship between image quality and printed solid ink densities. Six different solid ink density prints were produced, including solid ink density 0.8, 1.0, 1.2, 1.4, 1.6 and 1. 8. A paired comparison evaluation procedure was used to determine which of solid ink density prints was the best in this experiment. The optimum tone reproduction corresponding to the solid ink density which produced the best possible image quality is shown by this experiment. The image quality appears linear from solid ink density 0.8 through 1.4. Above solid ink density 1.4 the image quality increases slightly and peaks at solid ink density 1. 6. The differences of image quality from solid ink density 1.4 through 1.8 are considered small as determined from the judgement in this experiment.
