| 20090246377 | THERMAL INK JET INK COMPOSITION - Disclosed are ink jet ink compositions suitable for use in thermal ink jet printers. The ink jet ink compositions contain one or more volatile organic solvents, one or more humectants, one or more binder resins, and one or more colorants. The ink jet ink compositions may also contain additives such as a plasticizer and/or a surfactant. Embodiments of the ink jet ink compositions have short dry times, good adhesion to a variety of substrates, and/or long decap times. | 10-01-2009 |
| 20090273621 | SYSTEM AND METHOD FOR MAINTAINING OR RECOVERING NOZZLE FUNCTION FOR AN INKJET PRINTHEAD - A transducer capable of generating vibrational energy is positioned relative to an inkjet cartridge to impart a vibrational force to simultaneously vibrate at least a portion of each of a plurality of ink fluidic columns associated with a plurality of nozzles in a printhead of the inkjet cartridge to maintain or recover nozzle function. | 11-05-2009 |
| 20100098860 | THERMAL INK JET INK COMPOSITION - A thermal ink jet ink composition includes one or more volatile organic solvents, one or more humectants, one or more binder resins, and one or more dyes. The one or more volatile organic solvents are selected from C | 04-22-2010 |
| 20100328398 | THERMAL INKJET PRINT HEAD WITH SOLVENT RESISTANCE - An inkjet printing system includes a print head in fluid communication with an ink reservoir and having a plurality of orifices and a corresponding plurality of associated ejection chambers. The print head includes a substrate and a barrier layer disposed on the substrate. The barrier layer defines in part a plurality of fluid channels and the plurality of ejection chambers. The barrier layer includes a material selected from epoxy-based photo resist materials and methyl methacrylate-based photo resist materials. An orifice plate is disposed over the substrate. The orifice plate includes the plurality of orifices in fluid communication with the ejection chambers. The orifice plate comprises a material selected from polyimides and nickel. | 12-30-2010 |
| 20100328401 | THERMAL INK JET INK COMPOSITION - A solvent-based inkjet ink composition for inkjet printing includes at least 50 weight percent solvent, a colorant, a humectant, from 0.3 weight % to 8 weight % of a binder resin, and not more than 5 weight percent water. The ink composition is compatible with components of a thermal ink jet printer. | 12-30-2010 |
| 20110141191 | SYSTEM AND METHOD FOR MAINTAINING OR RECOVERING NOZZLE FUCTION FOR A PRINTHEAD - A transducer capable of generating vibrational energy is positioned relative to an inkjet cartridge to impart a vibrational force to simultaneously vibrate at least a portion of each of a plurality of ink fluidic columns associated with a plurality of nozzles in a printhead of the inkjet cartridge to maintain or recover nozzle function. | 06-16-2011 |
| 20120013677 | Thermal ink jet ink composition - An inkjet ink includes an organic solvent, a resin, a surfactant, and a colorant. The ink has a decap time of at least about 1 minute. | 01-19-2012 |
| 20120013684 | Thermal ink jet ink compostion - A solvent-based ink composition for a thermal inkjet printhead includes (a) 55-90 wt. % of an organic solvent including a ketone and a C | 01-19-2012 |
