Abstract
An intermediate transfer member (34) (ITM) transfers ink solids from an image bearing surface to a substrate. The ITM has an outermost surface having an absorptivity of less than or equal to about 5 percent when measured after 36 hours of immersion in Isopar L at 100 degrees Celsius. An imaging liquid developer system (22) deposits the ink solids and an ink solids carrier onto the outermost surface of the ITM, wherein the imaging liquid developer system (22) is configured to supply the ink solids carrier at a reduced thickness or reduced density as compared to more absorptive ITMs.
Claims20
An imaging system comprising:
- an intermediate transfer member (ITM) operative for transfer of ink solids from an image bearing surface for a subsequent transfer to a substrate;
- the ITM having an outermost surface having an absorptivity of less than or equal to about 5 percent when measured after 36 hours of immersion in Isopar L at 100 degrees Celsius;
- and
- an imaging liquid developer system operative to sequentially deposit the ink solids and an ink solids carrier onto the outermost surface of the ITM, wherein the imaging liquid developer system is configured to supply the ink solids carrier at a rate of less than or equal to about 350 mg/lmpA3 at 100% image coverage.
An imaging system comprising:
- an intermediate transfer member (ITM) operative for transfer of ink solids from an image bearing surface for a subsequent transfer to a substrate, the ITM having an outermost surface having an absorptivity of less than or equal to about 5 percent when measured after 36 hours of immersion in Isopar L at 100 degrees Celsius;
- and
- an imaging liquid developer system operative to sequentially deposit the ink solids and an ink solids carrier onto the outermost surface of the ITM, wherein the imaging liquid developer system is configured to supply the ink solids carrier at a thickness on on-image areas of the outermost surface at a thickness of less than 0.6 um.
A method comprising:
- developing one or more layers of imaging liquid on an intermediate transfer member (ITM) having an outermost surface having an absorptivity of less than or equal to about 5 percent when measured after 36 hours of immersion in Isopar L at 100 degrees Celsius, the imaging liquid including ink solids and an ink solids carrier, wherein the ink solids carrier is supplied at a rate of less than or equal to 350 mg/lmpA3 at 100% image coverage;
- and
- transferring the layers from the ITM onto a print medium.
