Patent 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.
