  • Patent number: 9017772
    Abstract: Various embodiments provide methods and apparatus for forming intermediate transfer belts (ITBs) by combining a dip-coating process with a UV-curing process. In an embodiment, an ITB substrate can be immersed into a liquid coating composition contained in a dip tank and then withdrawn from the liquid coating composition. When exiting the dip tank, the coated substrate can enter a UV-curing chamber for a UV-curing process. Multiple cycles of dip-coating and UV-curing can be performed such that a desired ITB substrate coating layer thickness can be obtained. After coating the ITB substrate, the UV-cured coating composition can be released from the ITB substrate, wherein the UV-cured coating composition released from the ITB substrate forms the intermediate transfer belt.
