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.
Claims8
A method of producing a print on paper, comprising:
- drying a selected region of the paper to a moisture content not to exceed that of the paper equilibrated to 20% RH;
- depositing hydrophilic liquid in a selected fluid pattern on the selected region of the paper within 15 seconds after the completion of drying, so that the resistivity of the paper in the selected fluid pattern becomes no greater than 5×1011 Ω-cm.;
- charging the paper so that a charge pattern of charged and discharged areas is formed on the paper, wherein the discharged areas correspond to the selected fluid pattern;
- depositing charged dry ink having charge of the same sign as the charge in the charged areas on the paper onto the paper in a dry ink pattern corresponding to the selected fluid pattern in the selected region;
- and
- fixing the dry ink to the paper,
- so that the print has a maximum reflection density of at least 1.5.
