Ink filtration is an important part of any Flexo printing operation. As doctor blades wear, particles of steel are introduced in to the ink system. Particles can become lodged between the blade and the roll surface. These particles will polish down the tops of the cells and affect their volume carrying capacity and will show up as a light line in the print. Effective filtration of doctor blade shavings and other debris is the best method for assuring long life from your Anilox rolls. 30 Pound pull rare earth magnet.
