  • Ink development units for printers
    Patent number: 8103194
    Abstract: An ink development unit is disclosed for liquid electro photography (LEP) printers or the like. An exemplary squeegee on PIP (photo imaging plate) (or “SOP”) ink development unit for a liquid electro photography (LEP) printer system includes an ink dispenser configured to dispense ink during a printing operation. A developer roller having a compliant surface is positioned in contact with a PIP during a printing operation. The developer roller directly receives the ink dispensed from the ink dispenser. The developer roller squeegees the ink dispensed from the ink dispenser into an ink layer with higher solids concentration for development onto an image area on the PIP.
