摘要： The teachings as provided herein relate to a watermark embedded in an image, and methodology for same, that has the property of being relatively indecipherable under normal light, and yet decipherable under UV light. This fluorescent mark comprises a substrate containing optical brightening agents, and a first dot design printed as an image upon the substrate. The first dot design has as a characteristic, the property of strongly suppressing substrate fluorescence. A second dot design having a property of providing a differing level of substrate fluorescence suppression from that of the first dot design such that when rendered in close spatial proximity with the first dot design image print, the resultant image rendered substrate suitably exposed to an ultra-violet light source, will yield a discernable image evident as a fluorescent mark.

摘要： Extended colorant sets are used to hide data or provide a watermark in printed images. Extended set colorants are colorants other than, and in addition to, the standard or common subtractive primary colorants: cyan, magenta, yellow and/or black. Where the extended colorant set supports a plurality of colorant recipes for rendering a given color, watermark data is used to select a colorant recipe from the plurality. As the watermark data to be encoded in the image changes state with image position, alternate colorant recipes or colorant selection functions are selected. The image is rendered based on the alternate colorant recipe selections. Watermark information is encoded in the colorant recipe or colorant selection function selection. Use of the extended colorant sets allows information to be encoded even in portions of an image having colors that do not include a neutral component.

摘要： A spot color dictionary is fine tuned or updated. Localized color production models are determined for spot colors of interest to be produced by an associated document processing system or printer. Measurements are made of colors of produced spot colors. Optionally, measurements are made of colors of test patches that are based on perturbations from the colors of the spot colors. In determining a model for the production of a target spot color, measurement data related to colors that are closer in color space to a given target color is given a higher weight than is measurement data related to colors that are further in color space from the target color. Accordingly, the model is localized to the region of color space about the target color and therefore, more accurately predicts a colorant recipe for the target color than would interpolation based on a full gamut, or more general model.

摘要： A color transformation method which accounts for colorant interactions includes establishing a plurality of tone reproduction curves (TRCs), for one or more of the color separations forming a digital image. Each TRC accounts for colorant interactions between a primary colorant with which the first color separation is to be rendered and at least one secondary colorant with which at least a second of the plurality of color separations is to be rendered. The TRCs include input values and their corresponding modified input values. In a given TRC, the input values of the second and optionally other color separations are fixed. For a pixel of the digital image having a given input values for the first and second color separation one or more of the TRCs are selected which bound the fixed input value for the second color separation and a modified input value is determined therefrom.

摘要： Spatially dependent colorant interaction effects are identified and isolated from other aspects of spatially dependent colorant appearance nonuniformities. A decorrelating function for compensating for the identified spatially dependent colorant interaction effects is determined. Spatially dependent single colorant compensating functions for compensating for the other aspects of the spatially dependent colorant appearance nonuniformities may also be determined. Image data is processed through the decorrelating function, thereby generating colorant values that are compensated for spatially dependent colorant interaction effects. Optionally, image data is also processed through the spatially dependent single colorant compensating functions, thereby generating colorant values that are compensated for both aspects of colorant appearance nonuniformities. The two kinds of compensating functions may be determined, calibrated and/or stored at different spatial and temporal frequencies or resolutions. One or both of the compensating functions may be employed to maintain consistency across a plurality of rendering devices (e.g., marking engines).

摘要： Systems and methods preserve the information lost in gamut-mapping during marking (e.g., printing) such that the lost information survives the marking and recapture (e.g. scanning) process. Generally, an encoding method may include gamut-mapping and image for a particular device; determining a residual image; and embedding the information needed to recover the residual image within the pixels of the gamut-mapped image. Generally, a decoding method may include extracting the embedded information from the image; and using the residual image to restore the gamut-mapped image to the original image.

摘要： What is disclosed is an image processing method for enabling one to print color graphics and other recognizable objects on monochrome printers while retaining color differences. More specifically, the present method is for preserving color discriminability in a grayscale representation. The method involves first sorting colors according to at least one characteristic dimension of a color space such as lightnesses. The color space preferably is a luminance-chrominance color space, although others are envisioned. The sorted colors are adjusted by a metric appropriate to the color space such that the metric imparts a degree of distinction among the colors along the chosen characteristic dimension. The spacing between two adjacent sorted colors can be constant, or weighted by the total color difference between the two colors in the original color space. Color difference can be calculated using for example ΔE*ab, ΔE*LCh, ΔE*94, or DE2000 metrics. Once the colors have been adjusted, they are converted to the monochrome representation using straightforward techniques.
摘要翻译：所公开的是一种用于使得能够在保持颜色差异的同时在单色打印机上打印彩色图形和其他可识别对象的图像处理方法。更具体地，本方法用于保持灰度表示中的颜色辨别性。该方法包括首先根据诸如亮度的颜色空间的至少一个特征尺寸来分类颜色。颜色空间优选地是亮度 - 色度色彩空间，尽管其他设想也是如此。分类颜色通过适合于颜色空间的度量来调整，使得度量赋予沿所选特征维度的颜色之间的一定程度的区别。两个相邻排序颜色之间的间距可以是常数，或者由原始颜色空间中的两种颜色之间的总色差加权。色差可以使用例如DeltaE * SUB，ΔE*，LCh，DeltaE * 94或DE2000度量来计算。一旦颜色被调整，它们将使用简单的技术转换为单色表示。
