Possible Issues and Solutions

Ink Smearing or Blurring

Problem: Ink smearing or blurring can occur during the printing process, leading to poor print quality and reduced clarity of the printed image.


  • Ensure proper ink viscosity and consistency.
  • Adjust the doctor blade pressure to achieve a clean and even ink transfer.
  • Verify that the anilox roller is clean and free from dried ink or debris.
  • Check for excessive plate wear or damage and replace if necessary.
  • Optimize drying parameters to ensure proper ink curing.

Registration Issues

Problem: Registration problems result in misalignment of colors or images, causing a distorted or offset print.


  • Verify that all mechanical adjustments, such as gear settings and tension controls, are properly calibrated.
  • Check for worn or damaged gears, cylinders, or rollers and replace as needed.
  • Ensure the plate cylinder and substrate tension are correctly set.
  • Align the printing plates accurately and securely on the plate cylinder.
  • Regularly clean and maintain the registration sensors and control systems.
