Anilox rolls are the key elements of the aniline ink distribution system used in printing for processing of paper and textile materials.
Based on the recent developments in plasma science, a novel plasma-based functional coating laboratory facility for the ion-plasma-treatment of anilox rolls includes equipment for pre-heating, ion cleaning and magnetron sputtering. It is particularly suitable for the high quality depositing of metallic and ceramic coating onto the cylindrical outer surface of anilox rolls.

Features:

>

Ion purification system Magnetron system
Energy 300 – 2000 еV Activating gas nitrogen, oxygen
Working gas argon Working gas argon
Pressure (6 – 12) x 10-4 Torr Pressure (2 – 8) x 10-3 Torr
Diameter 10 – 40 mm Sputtering TiN rate 0,6 nm/s

Advantages:

Due to the incorporation of a plasma-based ion cleaning stage into the technological process, the film-substrate adhesion is increased and the overall production time is reduced.
A plasma-based approach to surface cleaning is a remedy for the environmental contamination problems posing by the chemical-based cleaning and depositing methods.

Applications:

  • polygraphia;
  • printing on paper and textile materials.

Developer:
