摘要:
A shutdown procedure is provided for removing all solvent ink from the printhead (28) of an inkjet printer system that uses volatile ink for printing. A shutdown method is provided for an inkjet printer that uses volatile inks for printing. Initially, a colorless flush fluid is provided which readily dissolves the ink. The flush fluid is crossflushed through the drop generator (34) and caused to weep out of the orifices in the drop generator (34) to dissolve and rinse away ink residues from the charge plate and the exterior of the orifice plate (40). The flush fluid is used to rinse off charging electrodes of the charge plate, the catcher face, and the catcher return line (76). Fluid crossflushed through the drop generator (34) cleans the interior of the drop generator (34) and cleans the crossflush valve (46).

A substrate coating is provided for application in association with ink jet ink imaging on the substrate. The coating material, for application on a printable substrate for use with an ink jet printing system, includes a substrate property enhancing component, a surfactant, and deionized water. When the coating material is applied to the printable substrate, prints are produced which have improved print quality. The coating can result in enhanced permanence of black and specialty non-black color ink jet prints, when the substrate enhancing component is a polymer. The coating material of the present invention can also be applied to the porous substrate as a pre-print coating to reduce paper cockle and curl, when the substrate enhancing component is a polyhydroxy compound.

A system and method are provided for fabricating an orifice plate (14) for use in an ink jet printing system. Initially, a substrate base (16) is provided, and a controlled-release layer (18) is applied to a surface of the substrate base (16). A conductive metal layer (20) is adherently coated on the controlled-release layer (18). At least one dielectric peg (22) is created on a portion of the conductive metal layer (20), and a nozzle layer (24) is applied on the conductive metal layer (20) to partially cover the dielectric peg (22). Photolithography is used to define a trench that covers the nozzles prior to formation of a second reinforcing layer. The controlled-release layer (18) is removed to separate the orifice plate (14) from the substrate base (12). The conductive metal layer (20) is selectively etched from the nozzle layer (24) to produce a completed multi-layer orifice plate (14).

A system and method are provided for correcting printed color and tone of a library of similar digital images. A single image (20) is selected from a library (10) of similar images, and manipulated with a set of unique transformations. Each of the manipulated images is processed for printing. Printer settings for actual job data are identified, and multiple reproductions of the selected image are printed at the identified printer settings for the job. Optimum transformations are determined by visual inspection of a full array of images, each of the full array of images having been manipulated by a different transformation prior to printing.

A substrate coating is provided for application in association with ink jet ink imaging on the substrate. The coating enhances permanence of black and specialty non-black color ink jet prints. The coating material of the present invention can be applied to the porous substrate as a pre-print coating or a post-print coating. The coating comprises a polymer, a surfactant and an electrolyte, with water.
摘要:
An improvement in the heating of ink in an ink jet printer having a printhead (34) and a fluid system (35) for supplying ink to the printhead via at least one umbilical (50), is provided. The improved ink heating technique proposes a fluid tube through which the ink flows and a heater (48) in close thermal contact with the fluid tube for supplying heat to a significant length of the fluid tubing. Thermal insulation can enclose the fluid tubing and the heater, and a protective covering can enclose the thermal insulation. An elastomeric layer can be situated between the fluid tubing and the heater, while maintaining close thermal contact between the fluid tubing and the heater.
