Abstract
A web making machine is monitored to identify at least one cross-machine direction (CD) actuator that is developing local mapping problems. The identified CD actuator and a segment of surrounding actuators are probed to determine a performance curve for the actuator. The center of an insensitivity region of the performance curve is selected as an optimal mapping alignment setting for the identified actuator with the setting for the actuator being updated. Global smoothing may also be accomplished by probing a global smoothness factor to generate a corresponding performance curve that is then similarly used to select an optimal value for the smoothness factor.
