Before a practical printing inspection is performed, a read test is performed. The read test is performed on one or more inspection samples by binarizing a multi-level image with brightness values for all gradations as a threshold value. A range (maximum value and minimum value) of readable brightness values is obtained, and then a median value between the minimum value and the maximum value is used as a binarization threshold value for a two-dimensional code image in a practical printing inspection."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Printing inspection device","description":"To obtain a printing inspection device that an optimum binarization threshold value in the printing inspection device that captures an image including a two-dimensional code printed by a general-purpo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11514256","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.
