| 摘要 | Systems and methods for print head calibration. In an exemplary embodiment, the method may include scanning an image on a print media to obtain an optical density profile. The method may also include selecting at least one window in the optical density profile. The method may also include generating an average profile for each window. The method may also include identifying variations in uniformity. | ||

| 主权项 | 1. A method for calibrating print heads, comprising: scanning an image on a print media to obtain an optical density profile, the optical density profile representing output from a plurality of print dies; selecting a plurality of windows in the optical density profile; generating an average profile for each selected window; and identifying variations in uniformity, based on the average profile for each window. | ||
