Abstract
A method of producing a print on paper includes drying a selected region of the paper to a moisture content not to exceed that of the paper equilibrated to 20% RH. Hydrophilic liquid is deposited in a selected fluid pattern on the selected region of the paper within 15 seconds after the completion of drying. The paper is charged so that a charge pattern of charged and discharged areas is formed on the paper, and the discharged areas correspond to the selected fluid pattern. Charged dry ink having charge of the same sign as the charge in the charged areas is on the paper is deposited onto the paper in a dry ink pattern corresponding to the selected fluid pattern in the selected region. The dry ink is fixed to the paper.
