Doctor blades.
A finer edge.
A better print.

Convertech Equipment manufactures precision doctor blades in India for rotogravure printing, flexographic printing and coating applications. Our blades are made from highly refined strip steel and finished with an extra-smooth edge for clean wiping of the gravure cylinder or anilox roller from start-up.

Available as Bonus® in India and Sureprint® worldwide, our range brings together high carbon steel, stainless steel and long life blades to suit your press and print requirements.

Resistance where it matters

Stainless steel doctor blades

High-quality stainless steel with corrosion resistance and long running life. A useful choice for water-based inks with extreme pH values, where the ink system demands more from the blade material.

Rotogravure printing

A smooth blade edge wipes excess ink from the gravure cylinder. Match the blade grade and edge to your print speed, ink and run length for consistent doctoring from start-up.

Flexographic printing

Accurate wiping of the anilox roller helps control ink metering. Select the blade material, thickness and edge configuration for your chamber, anilox and ink system.

Coating applications

Choose from steel grades and edge configurations to suit the coating process. Our range includes blades for solvent, water and UV-based inks and coatings, with technical advice on selection.

How do I choose the right doctor blade?

Carbon steel, stainless steel and long life grades address different wear and corrosion requirements. Share these details with our team for a recommendation.
