K Ceramic Doctor HQ®
K Ceramic Doctor HQ®

Standard Hardness: 850-900Hv

Essential for high-speed, long-run printing

K Ceramic Doctor HQ® was developed by reinforcing the durability and wear-resistance of the blade surface to reduce streaking, hazing, and other printing defects. The finely coated ceramic layer results in the blade edge evenly worn into small and uniform particles that can ensure consistent printing results and extended blade life.
