Dual camera print verification system

Dual Camera Print Verification System for leaflets :

A very efficiently designed system that contains two smart cameras from Topsenso,Germany. This system is used for the verification of the correctness of Pharma Leaflets / inserts and outserts. The cameras are installed on a leaflet folding machine. One camera verifies the upper surface while the other checks the lower surface of the leaflet.

The camera is smart enough to read and verify the following

  • Blank sheet / print presence.
  • A particular pattern / sequence of characters (Online Character Recognition).
  • Pharmacode with verification of its value.
  • 1 D Barcode with verification of its value.
  • 2 D Barcode (data matrix ) with verification of its value.

System Description:-

A large 15” display with touch screen. This facilitates the user to set the parameters of the job and the cameras and also view the image taken by the camera.

The cameras are mounted on the machine in such a way that the horizontal movement of the cameras is very easy and the vertical adjustment of cameras or sensors required is minimal.
