Causes of pollution:
1. The old blade blade is toughened.
2. Printing when the blade is too hard, printing speed too fast, viscidity too high.
3. The layout chromium is not complete, the chrome layer surface fine small thorn not polished off, or the layout is too clean roughness not enough.
4. Chromium hardness is not enough, printing scraper damage suites, full version of the scraper injury.
The solution:
1. Grinding scraper knife toughness, remove knife toughness or small gaps, can also replace the new soft blade.
2. Adjust the blade angle, reduce the printing speed appropriately and reduce the viscidity of the ink.
3. After the above adjustment, the version of fog is still not improved, only the chrome layer polishing again.
4. After printing the plate blade injury is very serious can only be done by the return of chromium polishing treatment.
