摘要： An electronic representation of the range of color combinations that can be displayed on the monitor is created and printed. The printed representation is then scanned by the scanner. A relationship is then identified between the monitor and the scanner. This relationship is then used as the basis to determine a relationship between the scanner and the monitor. Compensation is made for errors and the relationship is further developed. Finally, a scanner RGB to printer CMYK lookup table is built.

摘要： A method of transforming two color domains of an original target color profile in a universal color space includes receiving information characterizing the original target color profile. A non-flesh-tone domain chroma boost curve is constructed. The non-flesh-tone domain chroma boost curve is applied to the original target color profile to generate an intermediate target color profile. A flesh-tone domain boundary in the intermediate target color profile is determined. A flesh-tone domain chroma boost curve is constructed. A new target color profile is established by applying the flesh-tone domain chroma boost curve to the intermediate target color profile.

摘要： An improved “scattered data transformation” method for warping/morphing color data is provided to transform n-dimensional data so that only selected regions of the n-color space are modified. The method uses a set of “input points” that are chosen to represent the color gamut for an input color space. In addition, a set of “training points” having associated “training vectors” are chosen in the input color space, and the training points are used to define the transform output for the input points in the color input space. Some (or all) of the input points may also be training points, but it is not necessary that any of the input points be training points. The vector displacement effect of the preferred embodiment is both exponentially and inversely proportional to the distance of each of the input points to one or more of the training points so that, the closer a training point is to an input point, the greater the effect of that training point on that input point. If a training point is located beyond a pre-determined distance from an input point, then it will have no effect at all on that input point. A refinement of the present invention is to weight the vectors for the training points, so that certain training points can become much more “important” than others when modifying the input color space to the output color space.
摘要翻译：提供了一种用于扭曲/变形颜色数据的改进的“分散数据变换”方法以变换n维数据，使得仅修改n色空间的选定区域。该方法使用一组“输入点”，用于表示输入颜色空间的色域。另外，在输入颜色空间中选择具有相关联的“训练向量”的一组“训练点”，并且使用训练点来定义颜色输入空间中的输入点的变换输出。一些（或全部）输入点也可以是训练点，但并不需要任何输入点是训练点。优选实施例的向量位移效应与每个输入点与一个或多个训练点的距离成指数和反比，使得训练点越接近输入点，效果越大该投入点的训练点。如果训练点位于与输入点之间的预定距离之外，则在该输入点上根本不起作用。本发明的改进是为了训练点的向量加权，使得当将输入颜色空间修改为输出颜色空间时，某些训练点可以变得比其他训练点更重要。

摘要： A method and system are disclosed for creating and using space-efficient color tables in an imaging system having an imaging object. The imaging object has processing conditions associated therewith, and a full size color conversion data lookup table. The color linearity of the imaging object is determined. The processing conditions of the imaging object are classified into data groups based on color linearity. A full size shared color conversion data lookup table common to the processing conditions for each of the data groups is calculated, and a small size delta color conversion data lookup table for each of the processing conditions is calculated from the differences between the full size color conversion data lookup table and the shared color conversion data lookup table. In use, the shared standard color conversion data lookup table and lo the delta color conversion data lookup table, which are stored in memory, are retrieved and used to calculate the full size standard color conversion data lookup table,

摘要： Data in only three colors is printed in the three colors plus black. The coverage amount represented by the smallest intensity of the three colors is determined. When that amount is above a predetermined value at which observable grain becomes minimal, an exponent value is determined and a formula is followed. As an additional improvement, lightness is redefined on a model which favors less black at the lighter values and more black at the darker values. Hue is to remain the same, and is known from the original color data. The chroma is refined based on the original chroma, CMY and CMYK full gamut boundaries. Since black, lightness, chroma and hue are known, the new three color values are found by known techniques.
