HALFTONE SCREENS ENCODING SIGNATURES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240251050 titled 'HALFTONE SCREENS ENCODING SIGNATURES
Simplified Explanation: The patent application describes a method that involves determining a halftone screen in response to multiple requests by encoding a signature pattern in the halftone screen. Different requests may have different signature patterns, and when applied to image data for printing, the pattern is discernible to provide a unique signature for the output.
- The method includes determining a halftone screen in response to requests.
- Encoding a signature pattern in the halftone screen for each request.
- Different requests may have different signature patterns.
- The pattern is discernible in the printed output, providing a unique signature.
Potential Applications: This technology could be used in printing industries, security printing, document authentication, and anti-counterfeiting measures.
Problems Solved: This technology addresses the need for unique signatures in printed outputs, enhancing security and authenticity in printed materials.
Benefits: The benefits of this technology include improved security features in printed materials, enhanced document authentication, and better anti-counterfeiting measures.
Commercial Applications: The technology could be applied in the printing industry for secure document printing, banknote production, passport issuance, and other security-sensitive printing applications.
Questions about the Technology: 1. How does the encoding of signature patterns in halftone screens enhance document security? 2. What are the potential implications of using different signature patterns for different requests in printing applications?
Original Abstract Submitted
in an example, a method includes, at least one processor, in response to each of a plurality of requests, determining a halftone screen. determining the halftone screen comprises encoding a signature pattern in the halftone screen, and halftone screens for different requests may be encoded with a different signature pattern. the halftone screen may be arranged such that, when applied to image data to provide a printed output, the pattern is discernible therein to provide a signature for the printed output.
