ABSTRACT:
A porous back-shooting inkjet print head module is disclosed. The ink permeates through the porous ink supply layer into an ink chamber in contact with the outside by an injection hole, and the porous ink supply layer prevents the ink from flowing back. Therefore, the ink chamber is sealed very well and more pressure could be generated. The invention can thus be used for inks with high viscosities. It does not need a precision alignment process as in the prior art. This does not only increase the efficiency and yield of production, but also reduces the cost.
