Compared to other doctor blades, the special coating gives the printing press doctor blade, JT-70 doctor blade an outstanding durability and corrosion resistance, as well as prevents ink impurities from damaging the blade surface. The JT-70 blade can be used in soft packaging material printing equipment, coating machines, glazing machines, and rotary printing machines as a printing ink blade.
Compared to the DT-90 doctor blade, the JT-70 is less expensive, and can be used for long term usage in a printing press with a maximum speed of 500m/minute. That makes this blade ideal for printing presses with a low printing speed.
Parameter

A Lamella edge ensures the fast and precise contact of the blade and cylinder during the beginning of the printing process, thus reducing the blade wear rate.

The precise polishing process prevents ink from sticking to the doctor blade surface, thus prevents ink streaks and changes in print color.
The base material is made of a high quality steel to ensure a better durability and corrosion resistance.
The special coating reduces blade pressure during operation, and reduces cylinder wear, thus extending the blade service life.
