Software module, based on TubeScan digital strobe or TubeScan eagle view

  • Processing of all roll protocols in the network
  • Camera-based synchronization and visualization ensures best workflow stability
  • Control of the rewinder
  • Skipping of future defects shown in the roll protocol

If there is no roll protocol from the printing press,
you can use the TubeScan on the rewinder for missing label detection or even 100% print inspection – depending on your license package.
The TubeScan on the rewinder substitutes tiring strobe lights, commonly used for web monitoring.


on the PC

The software module QLink-Editor is installed on a separate PC (Windows 10). It can either be included in the order or supplied by the customer.

  • Processing of all roll protocols in the network
  • Roll protocols can be visualized and edited for further converting

Your benefits

In comparison to previous inspection workflow systems, the cost for QLink workflow is significantly lower.

on the printing press

  • The QLink real-time editor enables you to evaluate defects already during the printing process. The printer can classify the defects as "not relevant" or "to be fixed" in the converting process.
  • Larger defect areas, such as missing ink, can be defined as waste zones. These can afterwards be removed on the rewinder in one single step.
  • The net count is automatically updated after each editing. No more costly overproduction just to make sure there is enough good material.
  • Through innovative compression, the file size of the protocols is as low as 10% of the usual roll protocols (JPEG / BMP). This saves disk space and expenses and it will speed up your data transfer.

  • The camera based synchronization is easy to set-up and very reliable – in contrast to the sensor-based systems that are commonly used.
