A relatively thick-bodied doctor blade made of a low friction plastic material includes a seal relief bevel of between approximately 5 and 10 degrees. The blade then tapers to a tip support shape and tip of between approximately 0.001 and 0.005 inch. When used in conjunction with a chamber type inking system, the doctor blade cooperates with the chamber end seals to form a more positive and controlled seal therebetween.
