For several common inkjet, laser and thermal dye printers, a method of evaluating prints that is not associated with the level of dental expertise of the observer is introduced. In addition, an automated analysis that mimics the observations made by observers is tested. Metrics that are evaluated in this study include spatial resolution, contrast uniformity, the type of paper, and overall observer preference. The results demonstrate that observer preference is associated with a high print contrast uniformity and with the use of glossy paper, but not with increased spatial resolution. The automated analysis produced results that were in general agreement with the observer data for spatial resolution, which concluded that the Lexmark C543DN printer produced prints with the highest spatial resolution. A thermal dye printer (Kodak CMI1000) produced prints with the highest contrast uniformity, and the print most favored by observers overall was produced by the Kodak ESP-9 inkjet printer on Kodak Everyday Glossy Photo paper.
