The Science of Doctor Blades

Premature blade wear

Cause: Excessive pressure on the doctor blade can be blamed for premature blade wear, as can poor quality or improper blades, and a rough anilox surface, said Stamey. "When running a Lamella tip blade, the thinner the tip, the faster it will wear on a coarse anilox," he said. Or as Ritz said, "The coarser the engraving, the thicker the blade tip needs to be."
