- Contamination of the impression roller surface
Effects
- Poor expression

In the gravure printing unit, the high speed of the forme cylinder creates ink mist. This very fine ink mist is deposited on all surfaces. The rotating impression roller surface is particularly critical here. This can have a negative effect on the print image and damage the impression roller.
