Abstract
An ink jet device selectively ejects droplets of non-marking liquid ink into cells of a printing member in a desired latent negative image pattern. Certain cells of the printing member are filled with pigmented ink to create a desired image. An electrical bias is applied for fractionating pigment in the pigmented ink from liquid and transferring an image-wise pigmented ink pattern from the printing member to a receiving member, leaving behind a substantial portion of liquid. The receiver can be an intermediate member whereby the image-wise ink pattern is transferred from the intermediate member to a final receiver, while such receiver is in operative association with said intermediate member.
