Ink
Multi roller system versus TRESU chamber doctor blade system
A too thick ink layer with a multi roller ink system is due to lack of consistency from the rubber rollers and the fact that the operator
as a matter of precaution always uses a too thick ink layer in connection with a multi roller ink system. This will in practice increase
the ink consumption.
Ink consumption is reduced by approx. 15-20% by using the TRESU chamber doctor blade system.
