    • A color printing method includes converting source color data to intermediate color data represented in a device independent color space using a first multidimensional gamut mapping of the first device dependent color space to the device independent color space. The device independent color space has a neutral color component. The method further includes converting the intermediate color data to destination color data represented in a second device dependent color space using a second multidimensional gamut mapping of the device independent color space to the second device dependent color space. The second device dependent color space has three primary color components and a virtual black color component defined by substantially equal tonal values of the three primary color components. The second multidimensional gamut mapping includes a mapping from the neutral color component of the device independent color space to the virtual black color component of the second device dependent color space.
    • 彩色打印方法包括:使用第一设备依赖颜色空间的第一多维色域映射与设备独立颜色空间将源颜色数据转换为在与设备无关的颜色空间中表示的中间颜色数据。 设备独立颜色空间具有中性色彩分量。 该方法还包括使用设备独立颜色空间的第二多维色域映射与第二设备依赖颜色空间将中间颜色数据转换为在第二设备依赖颜色空间中表示的目的地颜色数据。 第二设备依赖颜色空间具有三个主要颜色分量和由三个主要颜色分量的基本相等的色调值定义的虚拟黑色分量。 第二多维色域映射包括从设备独立颜色空间的中性色彩分量到第二设备依赖色彩空间的虚拟黑色颜色分量的映射。

    • An apparatus, method, system and medium are described that support functionality to receive document(s) to be printed at a printing device, and enable editing the document(s) prior to printing. Modifications to the document(s) may be generated based on the user edits, and a print preview of the modified documents may be displayed and may enable further edits. In some embodiments, the print preview may be provided to the user on a display that is part of the printing device. In some embodiments, the print preview may be provided to the user through a UI presented on a client device. Display of the modified document(s) may be a rasterized image of the modified document(s), generated based on capabilities of a selected printing device. In some embodiments, modifications may be made to an intermediate version of the document(s), and that intermediate version may be cached.
    • 描述了一种装置,方法,系统和介质,其支持在打印装置处接收要打印的文档的功能,并且能够在打印之前编辑文档。 可以基于用户编辑来生成文档的修改,并且可以显示修改的文档的打印预览,并且可以启用进一步的编辑。 在一些实施例中,可以在作为打印设备的一部分的显示器上向用户提供打印预览。 在一些实施例中,可以通过客户端设备上呈现的UI来向用户提供打印预览。 经修改的文档的显示可以是基于所选择的打印设备的能力生成的经修改的文档的光栅化图像。 在一些实施例中,可以对文档的中间版本进行修改,并且该中间版本可以被缓存。
