  • Patent number: 8582178
    Abstract: A method for reducing an amount of marking material for printing a binary image on a receiving material uses a printing process configured to apply print pixels and to associate each image pixel with at least two print pixels. A print signal is generated indicating for each print pixel whether marking material is to be applied. The print signal is filtered by a predefined mask that defines for which print pixels no marking material will be applied independent of the pixel value of the associated image pixel. The print pixels that are blocked by the mask define a regular pattern to avoid graininess in the printed image. The main effect on print quality is a reduction of the contrast in the image. By choosing one of a set of at least two masks, the user selects the amount of reduction that is realized in the print process.

    Abstract: An original design image is processed to create a modified design image for blending with an image of a product to create a combined image representing the result of printing the design image onto the product. To create a modified design image, both the alpha value and color of pixels in the original design image are modified. The modified alpha value and the modified color of a pixel are determined as a function of the amount of gray in the original color of the pixel. The modified pixel color is calculated by subtracting the level of gray in the original pixel color from each of the three original component color values and increasing any remaining color component values as a function of the modified alpha value of the pixel.

One plane contains black (e.g., achromatic) content, while the other contains highlight color content. Black pixels are identified and/or determined using neutral pixel and neutral window detection. Background pixels are mapped to white for both planes. Pixels that are non-neutral and non-background are designated as color pixels. After separation into a neutral plane and an HLC plane, the planes are processed into binary data for printing.

  • Patent number: 8054504
    Abstract: A method separates a color vector into a colorant vector for a printing system that uses more than four colorants, for example cyan, magenta, yellow, black, orange and green colorants. According to the method, the separation process is split up into partial four colorant processes that contain opponent colors. For example, a first partial process is a cyan, magenta, yellow and black process; a second one is an orange, magenta, yellow and black process; and a third one is a cyan, green, yellow and black process. Continuity of magnitudes of the colorants is achieved across the boundaries of the color gamuts of the partial processes by imposing specific constraints on the combinations of colorants to render a given color. A computer implemented system and a print system are based on the method.

  • Patent number: 7742205
    Abstract: The invention relates to a color matching method for transforming a color representation of a first set of color primaries with a plurality of first signals to a second set of color primaries with a plurality of second signals in a first domain. The color matching method of the invention is to consider the characteristics of human visual perception. Since human is more sensitive to the luminous intensity than chrominance, the color matching method of the invention is considered to match the luminous intensity. The color matching method of the invention can minimize the intensity difference by utilizing the optimality of resource distribution. An additional step of smoothing the intensity difference among color primaries at the level of color primaries is appended. It enhances the visual quality especially for the images with a gradual change in numerous levels of color. Besides, when the color is outside the gamut, we keep the information of luminance by adding extra white.

  • Patent number: 7692830
    Abstract: A luminance nonuniformity adjustment module for eliminating luminance nonuniformities in light emitting elements determines a luminance correction coefficient for each light-emitting element through a test print. The luminance nonuniformity adjustment module comprises a provisional luminance correction coefficient calculation unit, an improper coloring degree calculation unit and a luminance correction coefficient determination unit. The provisional luminance correction coefficient calculation unit calculates a provisional luminance correction coefficient by comparing a measured density value for a grayscale chart and a predetermined target density value. The improper coloring degree calculation unit calculates an improper coloring degree, which is the degree of improper coloring that occurs when other colors are expressed when developing a specific color, from the measured density values for the grayscale chart and an unbalanced chart in which the gray balance has been altered.

  • Patent number: 7583409
    Abstract: A method for encoding information on a printed page includes generating a set of color patches, each having a unique color. The set of color patches is printed. The printed color patches are scanned to identify color values for each patch in the set of patches. For each patch, the identified color values are associated with a datum value in a data structure. A page which includes a patch code is printed. The patch code includes selected ones of the set of color patches for conveying information about the printed page. The printed page is scanned to identify the color values for the color patches in the patch code. The data structure is accessed to identify the data values for the identified color values of the patches in the patch code. Information about the printed page is determined from the identified data values.

  • Patent number: 7577312
    Abstract: Motion picture scenes to be colorized are broken into separate elements, backgrounds/sets or motion/onscreen-action. Background and motion elements are combined separately into single frame representations of multiple frames which becomes a visual reference database that includes data for all frame offsets used later for the computer controlled application of masks within a sequence of frames. Each pixel address within the database corresponds to a mask/lookup table address within the digital frame and X, Y, Z location of subsequent frames. Masks are applied to subsequent frames of motion objects based on various differentiating image processing methods, including automated mask fitting of all masks or single masks in an entire frame, bezier and polygon tracing of selected regions with edge detected shaping and operator directed detection of subsequent regions. The gray scale actively determines the mask and corresponding color lookup that is applied in a keying fashion within regions of interest.

  • Patent number: 7436545
    Abstract: If an ink for a particular color (for example, red) having an excellent color developing characteristic is used in addition to inks for three primary colors of subtractive color mixture, the high color reproducibility is to be maintained for a long period. To accomplish this, at least one (for example, a yellow ink) of the inks of two colors between which the hue angle of red, included in the three primary colors, is sandwiched is applied to an area of a printing medium to which a red ink is applied so that the inks overlap each other. Thus, the yellow ink, having a high weatherability, is applied to an area on the printing medium to which only the red ink, having a low weatherability, is otherwise applied. It is therefore possible to improve the weatherability while maintaining the color developing characteristic at a high level.
