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.
Claims14
A process for the printing of images comprising:
- providing a roller having a surface;
- providing an array of styli opposed to the surface;
- providing a flow of liquid ink containing charged ink particles between the array of styli and the surface;
- providing voltage to the styli creating a voltage bias between at least one stylus in the array of styli and the surface;
- and
- plating at least some charged ink particles onto the surface in response to the voltage bias;
- wherein the providing the voltage bias step and the plating step are performed substantially contemporaneous,
- wherein the voltage applied to the styli is greater than any residual voltage of the roller.
