Stopping ink spitting at high speeds requires a multi-faceted approach focusing on the Doctor Blade and ink properties. First, ensure that the blade has a specialized "lamella" or rounded tip that maintains constant contact even under high hydrodynamic pressure. Reducing ink viscosity slightly can also help the ink flow more smoothly within the Cell Volume, reducing the buildup behind the blade. If the pressure becomes too great, the blade can "hydroplane," allowing ink to escape; therefore, setting the correct contact angle (typically between 30 and 35 degrees) is essential for a clean wipe.

Another critical factor is the anilox specification. High-line-count rollers with shallower Cell Depth often exhibit less spitting because they carry less air into the ink chamber. Switching to anilox rollers with advanced engraving patterns that facilitate air release can also mitigate the pressure spikes that lead to spitting. By combining high-quality blade materials with precise ink management, printers can maintain high speeds without sacrificing the visual integrity of the packaging.
