  • Patent number: 7751086
    Abstract: An image processing apparatus configured to generate image data for forming an image using a plurality of color materials of similar colors and of different densities includes a gradation changing unit configured to conduct a gradation changing process for changing gradation of C, M, Y, and K signals of an image and a color separation unit configured to conduct a color separation process for separating color component data for a dark color material into color component data for a dark color material and color component data for a light color material. The gradation changing unit is configured to conduct the gradation changing process before the color separation unit conducts the color separation process.

  • Publication number: 20100033778
    Abstract: When color materials of more than four colors are used, a signal for the amount of toner used within a range appropriate for the apparatus and toner characteristic is generated using a color separation table. However, a printer receives print data of various formats, such as image data separated into signal values of more than four colors, or image data of a special format to which a six-color separation table cannot be applied. Hence, an image signal representing a combination of colors is input. The sum of the signal values of colors in each pixel of the image signal is calculated and compared with a limit value. When the sum exceeds the limit value, the signal values of base colors are replaced with that of a spot color based on a replacement table for replacing the signal values of the base colors with that of the spot color.

  • Publication number: 20070046961
    Abstract: A combination to minimize moiré can be determined theoretically or empirically in four-color printing, but it is very difficult to find a combination to minimize moiré in printing using five or more colors. To solve this problem, image data is color-separated into image data corresponding to plural colorant. Multilevel dither processing is performed to the image data corresponding to the plural colorant. At this time, dither matrices having the same screen angle, the same screen ruling, and different threshold setting methods are applied to the respective image data corresponding to dark colorant and light colorant having the same hue and different lightness values.

  • Publication number: 20070024880
    Abstract: There is known a technique of inputting the contents of image data and the use purpose of a print material and automatically selecting a combination of color materials appropriate for them. However, it cannot be confirmed before printing whether improvement of image quality commensurate with the cost and labor to input contents information can be obtained. To solve this problem, the ratio of the amount of the color material of a spot color used to that of the color materials of process colors used in input image data is calculated. The recommendation grade of printing using the spot color is determined on the basis of the ratio. Further, display of the recommendation grade is controlled.

  • Publication number: 20060165866
    Abstract: Legume-derived, and particularly soybean-derived, water-soluble polysaccharides are added to thickener-containing powder supplied with an instant food to prevent clumping of powder masses during reconstitution and for a more homogeneous reconstitution. Thus, the problem is solved which is encountered with soup powders such as a thickened soup powder and a curry-seasoned soup powder, which are supplied with instant foods such as instant noodles, containing thickeners such as starch or gum substances to impart thickness, whereby reconstitution in a stationary state produces swelling of the thickener and prevents adequate dispersion, resulting in scattering of powder masses in the soup and clumping at the bottom of the container and, thereby, impairing the taste.
