CF380 – compact finishing machine

LESKO CF380

LESKO CF380 is a modern and compact construction used for post digital printing refinement of labels. The main advantage of this structure is its clever design which combine many functions in compact frame of machine.

Machine can be used for:

  • 1 colour printing
  • varnishing
  • lamination
  • coldfoiling
  • die cutting
  • slitting
  • rewinding
