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 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.

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.

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 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.
