TO GENERATE A PRINT SPECIFICATION COLOR SEPARATION LOOK-UP TABLE |
| 摘要 |
In a method to generate a print specification color separation look-up table, a device color space is sampled to provide at least one sampled value. The sampled value is transformed to a device independent color space. The transformed sampled value is gamut mapped using a source color gamut and a color separation color gamut to provide a color separation value. The gamut mapping is performed in an expansion mode and a compression mode. |

1. A method to generate a print specification color separation look-up table, the method comprising:
sampling a device color space to provide at least one sampled value; transforming the sampled value to a device independent color space; and gamut mapping the transformed sampled value using a source color gamut and a color separation color gamut to provide a color separation value, the gamut mapping being performed in an expansion mode and a compression mode. |
