1. A method of evaluating color image quality of an output image from an image output device, comprising: a) viewing an output image from the image output device and a second image from a view point; b) identifying a distance between the view point to the output image and the second image where a visual difference between the output image and the second image become unperceivable; c) using the identified distance where the visual difference becomes unperceivable as a measure of color image quality.
