Abstract: A computer-assisted process for the design and placement of multi-colored patterns on absorbent substrates using a limited number of transparent process colorants is described. Through use of this system, a designer, working with a computer-aided design system, can generate and accurately represent on a computer monitor or similar display a multi-colored pattern, as that pattern would appear on a specified absorbent substrate, using coloring elements comprised of groups of multiple pixels in which process colors have been mixed in a controlled manner to expand the range of available colors, and to compensate for colorant delivery limitations that prevent the application of small, accurately metered quantities of colorant. Actuation instructions for a specific dye injection machine capable of patterning a moving textile substrate may be generated.

Abstract: A process by which dithering techniques may be used to reproduce a desired multi-colored dyed pattern on a substrate using precisely delivered quantities of liquid colorants that are available in only a relatively few colors. In one embodiment, the process is one in which a designer, working with a conventional computer-aided design system, can be provided with an image that accurately predicts the appearance of individual colorants, or a specific combination of colorants that are physically blended on the substrate within specified pixels, as those colorants would appear on the substrate selected by the designer. In other embodiments incorporating the process disclosed herein, specific actuation instructions for a specific dye injection machine capable of patterning a moving textile substrate may be generated.

Abstract: An apparatus and method for reproducing the color of blended colorants on an electronic display such as a cathode ray tube, liquid crystal display or other type of electronic device that utilizes RGB values. Predictions of blended colorants on or in substrates can be made from XYZ measurements of samples prepared with no colorants, one colorant, and pairs of colorants. The calculation method uses light absorption, light scattering, and light absorption blend coefficients. An image digitizer can be used to obtain XYZ values from samples. Furthermore, image digitizer RGB values are converted into XYZ values with a non-linear model using a simple method. Furthermore, the above process to generate XYZ values from image digitizer RGB values can be used to generate RGB values from XYZ values for electronic display.

Abstract: An electrically conductive textile fabric in which the electrical conductivity may be made to vary in a pattern configuration, and a method for manufacturing such fabric. A textile fabric is coated with an electrically conductive polymeric coating, and the coating is selectively removed in those areas in which a reduced electrical conductivity is desired. The removal may be achieved by means of high velocity water jets, sculpturing, or other means.
