Doctor Blades for Rotogravure Printing

Polygraphica's Lithodoc PLUS doctor blades are made from high purity refined carbon steel. Due to a novel shaping process of the lamella, there are no longitudinal grinding scratches or shed marks. The parallel zone of the lamella ends in a smooth taper called the dynamic zone which reduces vibrations and fatigue.

  • increased doctor blade life
  • contact area remains constant throughout life of the doctor blade
  • no change in tonal values through blade wear
  • easy colour matching
  • minimal doctor blade pressure extends cylinder life
  • less time required to run in the press
  • less wasted substrate
  • less down time caused through blade changes
  • no doctor blade grinding equipment required
  • constant conditions for proofing
