HI440 – inspection rewinder

LESKO HI440

Inspection machine LESKO HI440 is dedicated to work with the previously prepared materials. The machine is ideally suited for:
  • printed materials confectioning,
  • precise slitting.
  • inspection.
Our idea of inspection system fully integrated with the machine guarantees 100% control of printing quality and maintain very high efficiency.
