Abstract
A process and apparatus prints images. The process provides an imaging surface; an array of styli opposed to the imaging surface; and a flow of liquid ink containing charged ink particles in the ink between the imaging surface and the array of styli. A voltage bias is established between at least one stylus in the array of styli and the imaging surface. The voltage bias plates at least some charged ink particles onto the imaging surface in response to the voltage bias.
Claims17
A process for the printing of images comprising:
- providing an imaging surface;
- providing an array of styli opposed to the imaging surface;
- providing a flow of liquid ink containing charged ink particles in the ink;
- providing a voltage bias between at least one stylus in the array of styli and the imaging surface;
- and
- plating at least some charged ink particles onto the imaging surface in response to the voltage bias.
3 more elements
An apparatus for providing a printed electrostatic image comprising:
- an imaging surface;
- an array of styli that can be provided with a voltage;
- a supply of liquid ink that supplies liquid ink between the array and the imaging surface while the array of styli are provided with a voltage and then the voltage reduced;
- wherein the imaging surface is free of photoconductor material and the styli do not contact the imaging surface.
