Coated Doctor Blades
- Short Lamella Blade Edge
- Long Lamella Blade Edge
When working with high-viscosity inks and specialty coatings, maintaining smooth ink transfer while minimizing blade contamination is important. Coated doctor blades address these challenges by incorporating a special surface treatment that reduces ink adhesion and enhances corrosion resistance. The result is a cleaner, more stable printing process with improved blade longevity.
Unlike standard carbon steel blades, these feature a protective coating that enhances wear resistance and lubrication, ensuring a more controlled ink metering process. The improved surface properties help prevent color inconsistencies, blade streaks, and excessive friction, which can affect print clarity and plate lifespan. Our coated doctor blades are available in two variants, each designed for different printing needs. The GZ-100 model, made with a 2067 carbon steel base and a 6-10μm coating, provides enhanced durability and ink control for general applications. The GZ-200 model, featuring a gold-coated surface with a 10-15μm coating on a 20MC1 carbon steel base, offers higher anti-adhesion and corrosion resistance; ideal for demanding printing processes that require extended blade life and precision.
These blades provide enhanced wear resistance and reduced ink adhesion, ensuring effective performance with sticky, high-viscosity inks. The specialized coating helps prevent ink buildup, resulting in consistent print quality and less frequent maintenance.
The enhanced coating provides better resistance to corrosion and ink contamination, ensuring a more stable ink flow throughout the printing process. By reducing ink accumulation, these blades help prevent print defects and protect the anilox roller.
For inks with high pigment concentration and larger particles, the GZ-200 gold-coated doctor blade is the best option. Its reinforced coating improves durability and anti-adhesion performance, ensuring clean ink transfer and prolonging anilox roller life while maintaining print sharpness.
