Reservoirs and wicks

Essentra’s reservoirs and release wicks often work as a two-component system for highly efficient ink release at high resolutions. Engineered at microscopic level for purity and regulated capillary action, our storage and release components eliminate pigment contamination and deliver consistent and controlled retention and release of ink.

Reservoir Example
Cartridge wicks


  • Cube-shaped bonded fibre components that can be tailored to fit the application. Produced in double or triple density to improve ink release and offer a cost saving to the cartridge manufacturer.


  • Essentra wicks use a higher density, therefore having a stronger capillary pull force, compared with the reservoir. Because of this, the reservoir is engineered to pull precise amounts of ink from the reservoir at known speeds and volumes, enabling the print head to perform to its maximum ability.
