Conversion of K-only data from a source to a destination color space |
摘要 |
In an implementation, conversion of K-only data from a source CMYK color space to a destination CMYK color space is managed. The destination CMYK color space is transformed to a virtual RGB color space, in which a neutral axis of the virtual RGB color space is set to be mapped to destination K-only output colors in a color separation table for mapping of source K-only grays to destination K-only grays. The source CMYK color space is converted to a device independent color space and the conversion is adjusted such that the source K-only grays are forced to have the same chrominance as the neutral axis of the virtual RGB color space in the color separation table. The LUT is generated to include a K-only mapping by combining the virtual RGB color space with the adjusted conversion of the source K-only grays. |
