LABEL_REGISTRATION
Label registration-mark alignment with deadband trim of the applicator offset and drift detection.
When to use it
Use LABEL_REGISTRATION when a labeller applies pre-printed or wrap-around labels cut to a registration mark, the mark position is measured per label, and the applicator start position has to be trimmed to keep the cut on the mark.
Interface
