1. Thoroughly clean each anilox roll. Carefully place the anilox roller into the journal holder on the inspection table. After cleaning the end face of the same roller, print the serial number and the number of network cables.
2. Check the bearing movement. The bearing housing is flexible and should not oscillate.
3. Remove the bearing and check the inner bore of the bearing with a micrometer. If the inner bore of the bearing is severely worn (more than 0.0005 inches under the printing standard) or is scratched, the anilox roller should be sent out for journal repair.
4. Check the keyway for burrs. The burrs will prevent the flat key from being installed and repaired with steel files if necessary.
5. Carefully check the gear teeth. Tooth burrs and wear can cause printing problems and replace damaged gears.
6. Carefully inspect the entire surface of the anilox roll and mark the damaged area with a label.
7. Place the damaged anilox roller aside for the collar to check again. If the damaged area of the anilox roll is outside the normal printing range, it can also be used for individual printed printing. Even if the damaged surface of the anilox roll is within the printing range, it can be used for glazing, opaque white and glue applicators as long as the damaged area is marked.
8. Check the edge damage of the ceramic anilox roller. Many printers are accepting ceramic anilox rolls that have a slight break on the edges. If the edge is severely damaged, a filter must be installed to filter out ceramic debris and other impurities in the ink.
9. Record important data information for each anilox roll in the logbook. When you find the same problem on more than one anilox roll, you should pay attention to it and mark it on the roll for later inspection.
10. When returning the anilox roller to the storage, pay attention to whether the environment and conditions for storing the anilox roller are appropriate. Is the net group roller too close when stored? Is the surface between the anilox rolls in contact? Is there enough distance between the gears to not touch? Are ink drums, substrates, printed prints, and other things placed near the anilox roll? Does the operator have to get the anilox roller without having to work hard? If it takes a lot of effort to remove the heavier anilox roller, the operator may be too labor intensive and may cause damage to the anilox roller. The anilox rolls should be supported by the journals when they are stored and must never be stacked on top of each other. The anilox roller should be wrapped after cleaning to prevent accidental damage. Items that cover the anilox roll should be clean and dry.
11. Strictly check the cleaning area. Is there a good illumination in the cleaning area? Is it easy to clean the cleaning area after cleaning the anilox roll? Is the water tank clean if ultrasonic or water spray is used? Is the solvent clean? It is impossible to clean the anilox roller with a chemical cleaning agent that has been saturated with the residual ink.
12. Check the squeegee device. How long does the squeegee change? The old squeegee that has been replaced can no longer be used. Is the ink tank clean without dry ink consolidation? Is there a screw that hits the surface of the anilox roller and damages the surface?
