Abstract: A method measures chromaticity values using a colorimeter to solve the drawbacks of conventional technologies, such as an inaccurate illuminant, the filter of color-matching function being difficult to be deposited and manufactured within a filter mod colorimeter, and using an expensive spectrometer within a spectrum mode colorimeter. The spectrometer and the filter of color-matching function is not needed, and an accurate chromaticity value of an object by using a multi-band illuminant illuminating the object and a power meter. Further, the multi-band illuminant can adjust the illumination condition of a standard illuminator under different color temperatures, and the chromaticity values of the object can be measured under different color temperatures. The accuracy of the measured chromaticity values is up to the level of the spectrum mode colorimeter, and the price is less than the spectrum mode colorimeter.

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.
