  • Patent number: 6270189
    Abstract: An ink-jet printed product is formed by printing an image with a plurality of similar color inks having different concentrations and a special ink having a single concentration. In the product, graininess resulting from ink dots is decreased for all hues of the printed image. A decision is made as to whether or not a hue of an image to be printed can be printed with inks without the special ink of a color (for example, special color BL (blue)) having a single concentration. When it is decided that the hue of the image is to be printed with inks without the special color ink, data on ink color BL (blue) is decomposed into data on C (cyan) and data on M (magenta). The hue can be printed without the color BL, thereby significantly decreasing graininess in a portion having this hue.

  • Patent number: 6031974
    Abstract: The invention seeks to reduce amount of image data without detracting from picture quality, thereby lowering processing speed and holding down memory cost. While preserving the density of color image data, a computer compresses the color image data, which has been outputted by an image scanner, to a prescribed number of colors on the basis of the colors of inks. An image processor binarizes the results of compression, while preserving density, on the basis of ink colors. A main unit repeatedly prints a basic image, which is represented by the binarized image data, on cloth supplied from a supply unit.
