摘要： A non-atmospheric pressure vapor oven system that utilizes a controllable pressure zone to facilitate fast phase change heat transfer at any desired temperature to heat or cool flat substrates, and to level temperatures across different locations of the substrates. The system enables the use of a heat transfer fluid, such as water, without being limited to a particular temperature, such as the fluid's natural boiling point at atmospheric pressure. The system includes a vapor oven (hermetic enclosure) defining a pressure chamber having sealed entry and exit ports for transferring an object (e.g., a sheet of paper) with added material (e.g., toner) through the pressure chamber, and a pressure regulation apparatus for setting the saturation temperature (boiling point) of heat transfer fluid inside the vapor oven to an optimal heating/cooling temperature by selectively controlling the pressure inside the hermetic enclosure.

摘要： Methods and structures are disclosed to minimize the presence of vapor clouding in the path between an energy (e.g., radiation) source and the dampening fluid layer in a variable data lithography system. Also disclosed are conditions for optimizing vaporization of regions of the dampening fluid layer for a given laser source power. Conditions are also disclosed for minimizing re-condensation of vaporized dampening fluid onto the patterned dampening fluid layer. Accordingly, a reduction in the power required for, and an increase in the reproducibility of, patterning of a dampening fluid layer over a reimageable surface in a variable data lithography system are disclosed.

摘要： Methods are disclosed for applying a dampening fluid to a reimageable surface of an imaging member in a variable data lithography system without a form roller. Dampening fluid in liquid form is converted to vapor phase, and directed to the reimageable surface. The dampening fluid reverts to the liquid phase directly on the reimageable surface. Controlling the temperatures of elements of the delivery subsystem prevents unwanted condensation of the dampening fluid vapor on those elements. Generation and delivery of the vapor can be controlled in a feedback arrangement as a function of measured layer thickness formed on the reimageable surface to obtain a desired dampening fluid layer thickness formed on the reimageable surface.

摘要： An improved imaging member for a variable data lithography system comprises a reimageable surface layer comprising a polymer, the reimageable surface having a surface roughness Ra in the range of 0.10-4.0 μm peak-to-valley, and peak-to-valley nearest neighbor average distances finer than 20 μm. A structural mounting layer may be provided to which the reimageable surface layer is attached, either directly or with intermediate layers therebetween. The relatively rough surface facilitates retention of dampening solution and improves inking uniformity and transfer. The reimageable surface layer may be comprised of polydimethylsiloxane (silicone), and may optionally have particulate radiation sensitive material disbursed therein to promote absorption, and hence heating, from an optical source.

摘要： A subsystem for controlling the rheology of ink applied to an imaging surface of a variable data lithography system comprises an ink reservoir, an ink application subsystem for applying ink from the ink reservoir over the imaging surface at a first ink temperature, and an ink complex viscoelastic modulus control subsystem for modifying the complex viscoelastic modulus of the ink from a first value at the ink reservoir to a second value prior to transfer of the ink from the imaging surface to a substrate. The ink complex viscoelastic modulus control subsystem may comprise a partial curing stage, such as a photo-curing stage. The ink may optionally include photoinitiators to assist with the partial curing. Alternatively, the ink complex viscoelastic modulus control subsystem may consist of an ink pre-heating subsystem and/or a post-application cooling system.

摘要： An improved microvalve is described. The microvalve includes a corresponding actuation aperture in an actuation aperture layer. A control fluid flows through the actuation aperture. The flow of the control fluid is controlled by an electric field typically applied via a charge distribution near an actuation aperture layer. In one embodiment, the electric field may adjust the opening and closing of the actuation aperture thereby controlling the flow of the control fluid. In a second embodiment, the control fluid is an electrorheological fluid where the electric field controls the viscosity of the ER fluid thereby controlling fluid flow through the actuation aperture. In both embodiments the flow of the control fluid controls stretching of a flexible membrane formed along the wall of a conduit through which a fluid to be controlled flows. The stretching of the flexible membrane controlling the flow of the main fluid to be controlled.
