Print inspection with "GOLD" performances
Sentinel-Gold is an advanced quality control system for label based equipped with linescan camera.

Sentinel-Gold checks the print quality thanks to special verification functionality. It uses a high resolution linescan camera that allow the system to achieve a very high precision during the inspection.
Thanks to this specific technology it is possible to visualize and inspect all the parallel labels of one reel just with a single image.

Thanks to its highly flexible configuration Sentinel-GOLD can be easily integrated into any production line. The system can be integrated into the printing machine where the reel is stable. It is possible to configure the system to the reel width dimension and obtain an appropriate uniform illumination.
The integration directly into the printing machine guarantees an immediate alarm in case of printing problem and helps in the waste reduction.
Sentinel-Gold can be installed on the slitter machine too where the system can be directly connected to the machine and stop it in case of defect on the reel.

Sentinel-GOLD is used either to detect and classify defects or to improve the process and increase the productivity. When a defect is found, the operator is alerted and he can take action immediately avoiding large amounts of waste. The type of defect is logged in order to provide a detailed report for each roll.
Sentinel-GOLD ensures high levels of quality and offer the best solution for your production processes and converting operations maximizing yield, productivity, and quality. The reduction of waste and the optimization of the process help to rise the profits of the production.
