This infrared mark entails, a substrate reflective to infrared radiation, and a first colorant mixture and second colorant mixture printed as an image upon the substrate. The first colorant mixture layer in connection with the substrate has a property of strongly reflecting infrared illumination, as well as a property of low contrast under normal illumination against a second colorant mixture as printed in close spatial proximity to the first colorant mixture pattern, such that the resultant image rendered substrate suitably exposed to an infrared illumination, will yield a discernable image evident as a infrared mark to a suitable infrared sensitive device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Infrared encoding of security elements using standard xerographic materials","description":"The teachings as provided herein relate to a watermark embedded in an image that has the property of being relatively indecipherable under normal light, and yet decipherable under infrared illuminatio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8460781","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.
