LESKO RLS280PRN

LESKO RLS280PRN is the only one on the market so compact and multifunctional machine designed for printing and confectioning of labels.

The machine can be equipped with a rotary die cutting unit and the dual printing unit.

Usage of servo mechanism ensures off-line die cutting in register.

Additionally, there is possibility to use servo mechanism in one of printing units, which allows to print the third color.
