Features

Their high-hardness structure (HV800) combined with a dual-layer ceramic coating enhances resistance to wear and corrosion, ensuring long-term performance.

The reinforced ceramic edge minimizes blade wear, helping to maintain consistent ink transfer and print stability during extended production runs.

Smooth and precise ink distribution reduces tonal shifts, streaks, and fine blade lines, ensuring sharp and uniform print quality.

Excellent performance in gradient printing, barcode and QR code printing, and fine text applications, where detailed ink control is essential.

The high wear resistance helps prevent damage to the edges of the printing plate, contributing to longer plate life and improved production efficiency.

Printing with high-viscosity inks often leads to ink buildup on the blade, affecting print quality and increasing maintenance time. To counter this, these doctor blades are made from 2067 carbon steel and coated with a 6-10μm specialized layer that reduces ink adhesion and blade contamination. The protective coating also offers moderate corrosion resistance while preventing excessive ink accumulation on the back of the blade. This helps minimize streaking and ink smearing, ensuring clean ink transfer and stable print quality, even when working with sticky or slow-drying inks.
