1. A method of detecting image quality defects, comprising: providing an electronic image including electronic image data; rendering an image 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; optionally, deriving reference one-dimensional profiles from the electronic image data and generating difference profiles from the reference one-dimensional profiles and captured one-dimensional profiles; and evaluating at least one of the captured one-dimensional profiles and difference profiles for image quality defects.
