Abstract
Systems and methods are provided for calibrating a sensory array to ensure a robust cross-process registration measurement. The calibration is implemented using a calibration step that determines the signature error amount of a given image reading sensor. The signature error amount for the sensor is stored in a signature error look-up table. When the sensors are used to sense print head alignment, the correction may be implemented by accessing the signature error look-up table for the given sensor when calibrating the print heads. The signature error look-up table provides an amount of offset for each sensor that is used in determining the appropriate head position of a given print head to calibrate the print heads for the signature error associated with the given sensor.
