A porous material for channeling ink in an ink cartridge and a method for channeling the ink includes a porous material housed in an ink compartment of the ink cartridge. The porous material includes a body which has a protruding portion located proximate at the bottom. The bottom surface is bucking the ink cartridge according to the required ink gathering location and is squeezed to form an ink gathering zone that has a higher porosity locally to channel ink movement and reduce residual ink.
