摘要： A marking agent concentration method includes concentrating the marking agent by removing at least some liquid carrier between particles without substantially removing retained liquid carrier within the particles and without substantially modifying the particle structure, which is supported by the retained liquid carrier. The concentrated marking agent is supplied to distributors or end users of liquid marking agent. A concentrated marking agent includes solid clumps of agglomerated particles and a liquid carrier retained within the particles' individual structure. The clumps exhibit a median size greater than 90 μm. The concentrated marking agent exhibiting a solids content of from 40 wt % to less than 90 wt %. A hard imaging method includes combining a concentrated marking agent with additional liquid carrier, applying a shear force, dispersing particles from clumps, forming a liquid marking agent, and forming a hard image using the liquid marking agent.

摘要： Apparatus is described which, in use, applies a thin film of a wetting agent, such as water or a water-based solution, onto paper or other print medium before applying a liquid toner. The wetting agent is applied at a predetermined distance from an image transfer area. The wetting agent acts to promote adhesion of the liquid toner to the print medium. The adhesion of the liquid toner to the print medium is further improved by supplying the wetting agent at a temperature higher than room temperature.

摘要： 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.
