Print Striations

Ink is metered with a 2 roll system

Reduce ink on anilox roll by:

  1. Increasing metering roll pressure
  2. Using a harder durometer crown wipe roll
  3. Changing to doctor blade metering
  4. Changing ink formulation

Anilox rolls are plugged worn or dirty. Rolls have wide cell lands or coarse screens

Replace or clean anilox rollers. Change ink viscosity or formulations

Printing plate is too hard

Use plates with a softer durometer

Ink viscosity is too low

Raise ink viscosity by adding fresh ink

Printing plates are glazed

Clean or replace plates

Ink formulation is incorrect
