Doctor blades are designed to remove excess ink from the surface of the anilox roll. To achieve this, it's imperative to maintain consistent, light contact between the doctor blade and the anilox roll along its entire face. Variation from this ideal contact can lead to problems including inconsistent transfer of ink or coating to the substrate and premature anilox roll wear.

Several factors contribute to inconsistent contact between the doctor blade and the anilox roll:

1. Blade / Blade Holder Alignment: Ensure the blade is not skewed, offset, or misaligned with the centerline of the anilox roll.
2. Poor Blade Installation: Properly seat the blade in the holder and avoid overtightening to eliminate ripples or buckling of the blade.
3. Inconsistent Pressure: Maintain even pressure across the blade holder to prevent variations in blade contact.

Deviation from proper alignment often shows up as uneven ink or coating thickness.  Frequently operators try to overcome this problem by increasing blade pressure to compensate for the underlying issue.

This quick fix may temporarily address ink or coating problems but will eventually cause accelerated wear of both the doctor blade and anilox roll. Accelerated blade wear means more frequent blade changes and increased downtime. Accelerated wear of the anilox roll can lead to uneven or inconsistent ink or coating density.
