Abstract
An absorbent material is employed as a seal over the printhead nozzles. The absorbent is uni-axial to prevent ink migration laterally, implemented by a lattice of absorbent matter surrounded by ink barriers. Such an absorbent can be sufficiently effective to limit ink migration that a simple tape may be used to bind the absorbent over the orifices of an inkjet cartridge in the manner of a common bandage. The barriers at a minimum a located to surround and keep separate inks of different colors.
