Abstract:
1. A system for evaluating image quality in an image generating system comprising: at least one image generator configured to generate an image; an image capture device configured to generate a digital signal corresponding to a generated image; an image evaluator configured to process the digital signal to detect and correct anomalies detected in the generated image; a plurality of calibration tools having at least one printhead calibration tool configured to generate and correct an image with different printheads and a another printhead calibration tool configured to generate and correct an image with a single printhead, each calibration tool being comprised of at least one test pattern, at least one set of detection criteria, and at least one set of anomaly correction parameters, the plurality of calibration tools being configured to generate and evaluate images generated with an ink ejecting device; and a controller configured to select the calibration tools for operation of the at least one image generator and the image evaluator in accordance with a predetermined sequence that attenuates changes arising from application of anomaly correction parameters of one calibration tool upon a later selected calibration tool.
