The processor automatically compares the extended gamut of the lower-resolution first bitmap and the main color gamut of the printing engine to identify image quality improvement pixels of the extended gamut that are outside the main color gamut. The processor automatically either raster image processes the print data with the main colors and one of the optional colors, or raster image processes the print data with only the main colors, based on whether the number of image quality improvement pixels of the extended gamut that are outside the main color gamut exceeds a pixel quantity threshold, to produce a second, relatively higher resolution, bitmap."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Controlling use of optional colors in extended gamut printing based on pixels in gamut extension","description":"A processor of a printing device automatically raster image processes print data in a print job to produce a first, relatively low resolution, bitmap for printing the print job with the printer's main","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9819834","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
