Gamut Mode Selection for Extended Colorant Pixel Programming

The patent applies local quality by selectively applying extended gamut colorants only to specific pixels that benefit from them, rather than applying them uniformly across the entire image. The system identifies pixels where extended colorants provide measurable color improvement and applies these colorants only to those localized regions, thereby maintaining high color reproduction quality where needed while minimizing overall colorant consumption and cost.

The patent applies segmentation by dividing the image processing into distinct stages: first rendering the image in standard CMYK color space, then identifying specific pixels that would benefit from extended gamut colorants, and finally applying the extended colorants only to those identified pixels. This segmented approach reduces processing complexity compared to applying extended colorants to all pixels, while still achieving color accuracy improvements where they are most beneficial.

The patent applies self-service by implementing an automated system that performs gamut analysis and determines optimal pixel selection for extended colorant application without requiring manual user intervention. The system automatically compares standard CMYK rendering with extended gamut rendering, identifies benefiting pixels, and programs the print job accordingly, thereby expanding color gamut capabilities while maintaining ease of operation through automation.
