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.
