- a wider security thread 53 results in a correspondingly changed detector signal S.
- a pulse train F2 which due to the larger lateral overlap neighboring levels by a certain amount to larger values of the detector signal is shifted out and moreover due to the less sudden increase or decrease in the transition area from one Step to the next has a less angular course.
