Immediate detection of impermissible deviations early on in the wet and dry sections of the paper machine: Our inspection systems check the security paper at the earliest possible stage. Only material with flawless sheet geometry, zero paper defects, no water marks and no defects on security threads is allowed to pass to downstream process stages.
Our inspection systems inspect and measure the substrate immediately after paper formation. Defects in the security threads in particular (e.g. twisted threads) are detected in the wet section, so corrective measures can be taken quickly.
After drying, the security paper undergoes detailed inspection and measurement.
