Abstract
A novel method and system for calibration of paper feed in an ink jet printing system is used to remove overfeed bands and underfeed bands from an image. The method begins by feeding print media into the ink jet printing system. A color density test target is formed by simultaneously applying an on/off pattern print mask to print numerous print swaths while incrementing paper feed values. Each paper feed value corresponds respectively to each print swath. The color density test target reveals shifts from light to dark to light in order to identify a maximum optical density region. The paper feed value from the color density test target corresponding to a maximum optical density region on the color density test target is selected and entered into the printing system. The entered value calibrates printing system in order to minimize the presence of overfeed bands and underfeed bands while printing.
