The recognizably spaced printer output colors are in terms of a color space relevant to a color patch code or color barcode sensing device, and are related to the corresponding marking device input values."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optimal patch code design via device characterization","description":"A method for optimally using color patch codes or color barcodes for transmitting machine-readable information, via device characterization, is disclosed to comprise characterizing a printing device a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493621","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.
