摘要： A method of controlling a main fluid in a conduit using a microvalve is described. The microvalve includes a corresponding actuation aperture in an actuation aperture layer. A control fluid flows through the actuation aperture in response to an electric field 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 into and out of the conduit, thereby controlling the flow of the main fluid by opening or closing the conduit.

摘要： An cleaning subsystem for a variable data lithography system includes a first cleaning member having a conformable adhesive surface disposed for physical contact with an imaging member such that residual ink remaining on the imaging member, such as following transfer of an inked latent image from the imaging member to a substrate, adheres to the conformable adhesive surface and is thereby removed from the imaging member. The cleaning subsystem may further include a second cleaning member, in physical contact with the first cleaning member, having a relatively hard, smooth surface such that residual ink removed from the imaging member and adhering to the adhesive surface of the first cleaning member may split onto the second cleaning member.

摘要： A method of controlling fluid through a layer of a soft compressible (e.g., gel) material including an array of fluid flow paths. The fluid flow paths are normally open, allowing fluid flow. An electric field is applied in regions where fluid flow is undesirable. The electric field compresses the material closing the flow path thereby preventing further fluid flow.

摘要： Methods for controlling the rheology of ink applied to an imaging surface of a variable data lithography system include applying ink in a layer with a first complex viscoelastic modulus such that said ink layer readily separates in regions over the imaging surface covered by a dampening solution and into regions over the imaging surface at which dampening solution has been removed, increasing the complex viscoelastic modulus of the ink to a second complex viscoelastic modulus while the ink is over the imaging surface, thereby increasing the level of at least one of ink cohesive energy and ink tack prior to the transfer of said ink to said substrate at said image transfer subsystem.

摘要： A variable data lithography system includes an improved imaging member, a dampening solution subsystem, a patterning subsystem, an inking subsystem, and an image transfer subsystem. The imaging member 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： 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： A system and corresponding 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. In one embodiment, the system includes subsystems for converting a dampening fluid from a liquid phase to a dispersed fluid phase, and for directing flow of a dispersed fluid comprising the dampening fluid in dispersed fluid phase to the reimageable surface. The dampening fluid reverts to the liquid phase directly on the reimageable surface. In another embodiment a continuous ribbon of dampening fluid may be applied directly to the reimageable surface. This embodiment includes a body structure having a port for delivering dampening fluid in a continuous fluid ribbon directly to the reimageable surface, and a mechanism, associated with the body structure, for stripping an entrained air layer over the reimageable surface when the reimageable surface is in motion.
