Notices of using doctor blade
- Change doctor blade with serious wear immediately.
- Take apart the doctor blade holder to clean and clean the ink off of the doctor blade and top plate carefully and completely.
- Clean the doctor blade after use. Use alcohol to wipe the edge in order to make sure water evaporates and prevent the blade from rusting. A rusty blade will eliminate the effectiveness.
- Clean the ink in the blade holder inner in time. The ink will make the edge of the blade buckle and eliminate its ability to remove excess ink completely. This will negatively influence print quality.
- The high printing speed of the flexor printing press will wear the blade quickly and the debris from polyester plastic doctor blades will fall into ink box or be nipped between blade and cylinder, which will make these debris transpired to the cylinder and then influence the quality of the print.
- Due to good durability, steel doctor blades are usually installed at the opposite location and at an angle of 30°~40°.
- The angle and pressure of doctor blade is up to the air cylinder.
- The long term operation of flexor printing press will quicken the wear of blade. The right installation of blade is also important for printing.
