Abstract: Disclosed are various embodiments for systems and methods for calibrating a label applicator for improved accuracy and/or precision on moving objects. In one example, a system may be configured to receive a height of a package on a conveyor path prior to the package reaching a label applicator. The system can be configured to determine a predicted tamp time for the package based on the height. The predicted tamp time can represent an estimated period of time for a tamp head to apply a label on the package. The system also can instruct a controller operating a label applicator to activate the tamp head for the package based on the predicted tamp time. The system can receive an actual tamp time from the controller after the label has been applied to the package and update the modeling coefficient based on a tamp time error.
