Claim One:
1. A system for evaluating image quality in an ink printing system comprising: at least one printhead configured to eject ink onto an image receiving member to form an ink image that corresponds to a digital image stored in the ink printing system; a scanner configured to generate a scanned image signal corresponding to the ink image; a controller coupled to the at least one printhead, the controller being configured to generate firing signals that operate the printhead to eject the ink and form solid fill ink images on the image receiving member in response to a waveform adjustment test selection; and an image evaluator coupled to the controller, the image evaluator being configured to process the scanned image signal corresponding to the solid fill ink images and to generate firing signal waveform adjustments and image data adjustments, the firing signal waveform adjustments including printhead waveform voltage adjustments generated in response to intensity values in the scanned image signal being outside a range of predetermined solid fill intensity values, and the controller generates the firing signals with reference to the firing signal waveform adjustments and the image data adjustments generated by the image evaluator.
