Label Inspection Machine

Finding defects at final delivery is already too late. The ZB‑350 brings vision inspection into the roll‑finishing workflow, using the LUSTER Vision Inspection System to identify missing print, color variation, register deviation and scratches inline. Integrated slitting and dual web guiding make inspection a controlled production step—revealing issues earlier, limiting rework and increasing confidence in every finished roll.
