Reducing bounce via sleeves
The flexo industry has changed enormously in recent years, with developments in pre-press, anilox rollers, digital plate technology and sleeve-dedicated presses leading to the process being used in areas of print that would have once been unthinkable, including newspapers, folding cartons, labels and flexible packaging.

In an effort to highlight what printers can do to overcome this common issue, Trelleborg instructed a major printing research organisation to trial a selection of entry-level and high-end flexo sleeves at its state-of-the-art facilities in Germany.
