PerfControl is directly connected to the WSC module and is an inline inspection system used to detect deviating hole diameters or missing holes. The system is designed for transparent and printed flexible materials. High-speed cameras with inspection software, which actively readjusts the laser pulses for hole diameter alterations, or emits a signal in the event of missing holes or major deviations and stops the process.

The measured hole diameters are depicted on a diagram for each line of perforation.
