    • A system for converting a first representation of a color input image to a second representation and method for performing same are disclosed. The system includes apparatus for mapping primary axes and overprint axes of a selected color coordinate system to primary axes and overprint axes of a printer color coordinate system of the second representation, thereby to produce primary conversion tables and overprint conversion tables and apparatus for converting the first representation to the second representation utilizing the primary and overprint conversion tables. The system also includes printing apparatus for printing the second representation and for producing an output print, wherein the output print is a reproduction of the color input image within the selected color coordinate system. Furthermore, the system enables selection of operator-selected appearance parameters used to match desired printer conditions in accordance with the appearance parameters.
    • 公开了一种用于将彩色输入图像的第一表示转换为第二表示的系统和用于执行其的方法。 该系统包括用于将所选颜色坐标系的主轴和套印轴映射到第二表示的打印机颜色坐标系的主轴和套印轴的装置,由此产生主转换表和套印转换表以及用于将第一 使用主和套印转换表对第二表示进行表示。 该系统还包括用于打印第二表示和用于产生输出打印的打印装置,其中输出打印是所选色坐标系统内彩色输入图像的再现。 此外,该系统能够根据外观参数选择用于匹配所需打印机状况的操作者选择的外观参数。
