3 controls have to be executed on the labeller:
- unvisible DATAMATRIX code on the first side label of the product (visible by UV light),
- DATAMATRIX code on the back label of the product (black marking on white background),
- batch code and expiry date on the back label of the product.
These three controls are realised by one unique ILB-25N unit after the putting of the labels on the flask in movement. The speed is around 150/min.
