The methods herein evaluate at least two different regions of the printable item to determine spatial frequencies of the different regions, and calculate at least two marking material reduction values for the different regions of the printable item based on the spatial frequencies of the different regions. Then, the methods herein apply the marking material reduction values to the printable item to produce a file containing reduced marking material printing commands for a printing device to print the printable item."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optimal contrast level draft-mode printing using spatial frequency analysis","description":"Devices and methods herein receive a command into a computerized device to perform a printing draft operation of a printable item using a reduced amount of marking material (a reduced amount of ink, t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8467105","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.
