Carbon Steel Blade, Item CL-20 Doctor Blade
The CL-20 carbon steel blade is made of high quality German ZAPP 1247QA cold rolling carbon steel with a carbon content that is more than traditional carbon steel, thus extending the blade’s durability and lifespan.
The CL-20 doctor blade is a basic and common doctor blade that is suitable for printing presses with a speed of 250m/minute or above, making it applicable to a wide array of printing presses for ink removal.

- Compared to a traditional carbon steel blade, the CL-20 has a delicate microstructure and dense distribution.
- The precise polishing process can prevent ink impurities from sticking to the blade surface, thus ensuring a clear print pattern.
- The special technique used to process blade edge reduces the grinding process before using, thus saving time.
- Compared with to a CL-30 blade, CL-20 is less expensive and suitable for printing presses that require the blades to be changed on a more frequent basis.
