1. What is it?

It is one or several shiny, narrow lines on the circumeferial surface of anilox, indication of localized wear ( scoring) or deposits of foreign materials in the engraved cells.

2. How did it happen?
   (1) Doctor blade damaged;
   (2) Alien materials in the ink;
   (3) Incomplete cleaning of anilox roll after using;
   (4) Wrong matching of doctor blade and anilox roll
3. How to prevent it?
   (1) Magnets to trap metal element in the ink fountain and does not spread the ink alien materials to the doctor blade and further to the anilox;
   (2) Addition of filters in the closed-loop ink system with pump to trap foreign materials of any type;
   (3) Use geniune and good working doctor blades;
   (4) Proper clean of the anilox surface every time the printing is completed; use magnifer 100X or more to check the surface from time to time; use anilox brush, designated agent to clean the surface or ultrosonic sink to clean it; nowadays some also provide laser clean;

The basis philopsophy of anilox roll is using the cell to contain ink and transfer ink to the printing plate. You need to make the ink, cell, and transfer process as clean as possible to avoid the scoring line through joint efforts of operator, cleaning equipment, ink supplier, doctor chamber system.
