Application of TRESU Chamber Doctor Blade System
with Anilox Roller
The unique thing about the TRESU chamber doctor blade system with anilox roller used in ink systems is the
ability to apply a consistent ink layer.
The laser-engraved ceramic roller is consistent regarding circumference and longitudinal direction and in
combination with doctor blades this is the key to a consistent ink layer of the circumference and longitudinal
direction.
It is not possible to achieve a totally consistent ink layer with a multi roller (rubber/chrome) ink system because
the rubber roller cannot be made with the same accuracy in terms of circumference and longitudinal direction.
The consistent ink layer from the TRESU chamber doctor blade/anilox roller ink system means that a thin ink layer
provides a totally consistent coverage of both sheet directions. With a multi roller ink system this is not possible.
Here the thickness of the ink layer varies along the sheet and from the front to the backside. To achieve sufficient
coverage in the areas where the rubber/chrome rollers apply a thinner layer, some areas will get a thicker ink
layer than necessary. In average this results in a thicker ink layer.
Due to the consistent ink layer the tests and experiences that TRESU made in connection with leading
manufacturers of flexo printing machines and various key customers show that the TRESU chamber doctor blade
system in average uses 20% less ink layer for the same printing job. This is the main reason to achieve better
economy by using the TRESU chamber doctor blade system with an anilox roller ink system.
