Problems solved by technology

Due to the limitations of applying thermal drop-on-demand ink and the 300dpi limitation taught by Sporer, this method is only suitable for low-volume, low-speed printing applications requiring only mediocre image quality

Embodiment Construction

[0037] The terms "toner" and "dry ink" are used interchangeably herein.

[0038] As used herein, the term "paper" refers to a material generally made by pressing together damp fibers or fibers of a fabric. Paper comprises fibers derived from cellulose pulp derived from wood, chips or grass, and they are dried into flexible sheets or rolls. Paper generally contains moisture, which remains after drying or is absorbed by exposure to air. Thus, the term "paper" as used herein includes conventional materials marketed as paper and other materials with corresponding characteristics, such as canvas.

[0039] As used herein, oliophilic and hydrophobic liquids are defined as organic liquids that are immiscible or only slightly miscible with water. These include aliphatic and aromatic hydrocarbons. Hydrophilic and oliophobic are defined as liquids that are wholly or substantially miscible with water. These include water-based solutions and suspensions, such as inkjet inks containing ...

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.

Description

field of invention [0001] The invention belongs to the field of digital control printing system. Background of the invention [0002] Printers are useful for producing various types of printed images. A printer prints on a receiver (or "imaging substrate" or "recording medium"), such as a sheet or paper or other flat medium, glass, fabric, metal or other object. Examples of such media include fabrics, non-coated papers such as pound paper, semi-absorbent papers such as clay-coated papers commonly used in lithographic printing (e.g., Potlatch Vintage Gloss, Potlatch Vintage Velvet, Warren Offset Enamel, and Kromekote papers), and non-absorbent papers such as Polymer-coated paper. [0003] Printers typically operate using subtractive colorants: a substantially reflective recording medium is image-wise coated with cyan (C), magenta (M), yellow (Y), black (K) and other colorants. Various schemes are available for printing images. For example, inkjet printing deposits drople...
