Abstract: The present invention relates to aqueous ink jet ink compositions comprising an anti-intercolor bleed agent, preferably a water soluble or ink-compatible agent. The inks typically also comprise water and at least a colorant of a dye, a pigment, or a mixture of dye and pigment. In one embodiment, ink jet ink compositions comprising an anti-intercolor bleed agent which is represented by {[(R)m—G)b]n}s(A)(X)p (Formula (I)), and ink jet printing processes which print the ink jet ink compositions in any desired printing sequence or order onto an optionally heated substrate are provided. The water-soluble or ink-compatible anti-intercolor bleed agent may form hydrophobic layers near the image boundary, thus preventing undesired mixing of two different neighboring inks which forms intercolor bleed. The ink jet ink compositions of the present invention exhibit reduced drying time, intercolor bleeding, and image defect as well as providing uniform ink images on transparencies.

Abstract: A multicolor ink jet printing process employs an ink jet ink composition comprising water, a colorant of pigment, dye, or mixtures thereof, and a low boiling point additive to produce high quality multicolor ink jet images with minimal intercolor bleed and lines with sharp edges as characterized by a relatively low mid frequency line edge noise (MFLEN) number. The additive is an alcohol or thiol having a boiling point less than or equal to about 115° C. The aforementioned ink jet ink composition can further include an optional additive of alcohol or thiol with a boiling point less than or equal to about 135° C. if necessary. The desired additive increases the ink's drying rate with fast evaporation and an accelerated penetration into a print substrate (e.g. paper) upon printing. As a result, little or minimum residual ink (e.g. carbon black ink) comprising the aforementioned additive is available on the surface of the print substrate to intermix with a previously or subsequently printed ink (e.g. a color ink). As a result, the ink composition and multicolor ink jet printing process of the present invention can produce high quality images with minimal intercolor bleed and low MFLEN.

Abstract: The present invention relates to aqueous ink jet ink compositions comprising a water-soluble or ink-compatible anti-intercolor bleed agent and ink jet printing processes. The inks typically comprise at least water, a colorant of a dye or pigment, or a mixture of dye and pigment, and a water-soluble or ink-compatible anti-intercolor bleed agent. In one embodiment the water-compatible intercolor bleed agent of the invention comprises a fluorinated composition, more particularly a perfluoroalkyl acid salt. The water-soluble or ink-compatible anti-intercolor bleed agent can form hydrophobic layers near the image boundary, thus preventing undesired mixing of different neighboring inks which forms intercolor bleeding. The inks of the present invention exhibit reduced drying time, intercolor bleeding, and image defect as well as providing uniform ink image on transparencies.

Abstract: In an ink jet printing process, a desired vacuum is applied to the back side of a print substrate with proper feedback and control. The optimum vacuum exerts a suction force on ink dispersed on the front side of the print substrate to accelerate penetration of the ink into the print substrate and to reduce smear and intercolor bleeding. In addition, the vacuum may be applied in the ink jet printing process in combination with various other techniques including heating of the print substrate at any stage of printing process including before, during, after, and combinations thereof and delaying the time between ink dispersing of two different inks as in the checkerboard printing method. The employment of proper vacuum, inks, and printheads including partial-width or full-width array printheads allows a fast speed multi-color ink jet printing process to be carried out on a print substrate to give high resolution (e.g., 600 spi) multi-color images with good print quality.

Abstract: The invention includes an ink delivery and filtration medium for delivering and filtering ink from an ink chamber to a printhead in an ink jet system. The ink delivery and filtration medium comprises a porous woven material. The woven material can be made with fibers such as Nylons, polyethylene, polypropylene, polyethersulfone, polyesters, polyvinylidene fluoride, polytetrafluoroethylene. The woven material is flexible, thermally stable and chemically resistant to ink. The pore size and porosity of the woven material can be controlled by controlling the number of stitches per inch, fiber stitching pattern and fiber thickness or diameter. In addition, the pore size can be controlled by layering the woven material in combination with woven materials of the same or different pore sizes. Accordingly, not only can the pore size of each layer be controlled, but the pore size of the entire medium can be controlled by cumulative stacking of layers of materials with same or different pore size. The ink delivery and filtration medium provides smooth ink flow to the printhead without undesired ink clogging and impedance thereby substantially minimizing or eliminating jetting problems such as missing jets, exploding jets, and ink misdirection. In addition, restricted ink flow due to inefficient filtration and blockage of the filter by particles, debris or fibers, which causes slow ink refill and air ingestion problems resulting in slow printing speed and poor ink jet print quality can also be avoided or minimized by the steady and strong flow of ink produced with the invention.

Abstract translation: 本发明包括用于在墨水喷射系统中将油墨从墨水室传送到墨水打印头的墨水输送和过滤介质。 油墨输送和过滤介质包括多孔编织材料。 编织材料可以由尼龙，聚乙烯，聚丙烯，聚醚砜，聚酯，聚偏二氟乙烯，聚四氟乙烯等纤维制成。 编织材料是柔性的，热稳定的并对油墨具有化学耐性。 可以通过控制每英寸的针数，纤维缝合图案和纤维厚度或直径来控制编织材料的孔径和孔隙率。 此外，可以通过将编织材料与相同或不同孔径的编织材料组合来分层孔径。 因此，不仅可以控制每层的孔径，而且可以通过累积堆叠具有相同或不同孔径的材料层来控制整个介质的孔径。 油墨输送和过滤介质提供了平滑的油墨流动到打印头，而没有不希望的油墨堵塞和阻力，从而基本上最小化或消除诸如丢失喷嘴，爆炸射流和油墨错误方向的喷射问题。 另外，由于低效的过滤引起的墨水流动受限和颗粒，碎片或纤维的过滤器的堵塞导致缓慢的墨水补充和导致打印速度慢和喷墨打印质量差的空气摄取问题也可以避免或最小化 本发明生产的油墨稳定而强劲。
