1. A method of detecting image quality defects, comprising: providing an electronic image including electronic image data; with a printer, rendering a rendered image on print media based on the electronic image data; capturing the rendered image, the captured image including captured image data; deriving one-dimensional profiles from the captured image data, each of the captured one-dimensional profiles being derived from a set of image data in the same direction; and evaluating at least one of the captured one-dimensional profiles and difference profiles for periodic behavior indicative of image quality defects, wherein the evaluation of the difference profiles includes deriving reference one-dimensional profiles from the electronic image data and generating the difference profiles from the reference one-dimensional profiles and captured one-dimensional profiles.
