Abstract
The present invention provides an ink filter for an inkjet print cartridge, the print cartridge having nozzles for dispensing ink from an ink supply. The filter is formed of a polymeric material and is configured to prevent particles in the ink supply from passing to the print nozzles. The polymeric filter material is overmolded in a carrier which is configured to be coupled between the ink supply and the print nozzles.
