The precise polishing process can prevent ink from sticking to the surface of doctor blade and the appearance of ink streaks.
The most approprate contact angle of blade and cylinder is 60 degree. At the angle, the pressure of blade is lowest and can reduce cylinder wear.
The special coating can prevent the impurities of ink from damaging the surface of blade, improve the lifespan and oxidation resistance.
DT-90 with good durability is suitable for all kinds of inks and cylinders, especially durable inks and cylinders.
