Conclusion
The Tampere University of Technology study concludes:
- Plasma is more effective than flame and corona.
- The same or higher effect can be reached with 50 % lower efficiency compared to Corona and flame.
- Surfaces that are plasma treated have the lowest rub-off values.
- Plasma treatments are more uniform in comparison with Corona and flame. This results in a more even print and therefore better quality.
