HALFTONE SCREENS ENCODING SIGNATURES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18625449 titled 'HALFTONE SCREENS ENCODING SIGNATURES
The method described in the abstract involves determining a halftone screen in response to multiple requests by encoding a signature pattern in the halftone screen. Different requests may have halftone screens with different signature patterns, which can be discernible in the printed output to provide a unique signature.
- The method involves determining a halftone screen for each request by encoding a signature pattern.
- Different requests may have halftone screens with different signature patterns.
- The signature pattern in the halftone screen provides a unique signature for the printed output.
- When applied to image data, the pattern is discernible in the printed output.
Potential Applications: - Printing industry for unique identification of printed materials - Anti-counterfeiting measures for documents and products
Problems Solved: - Providing a unique signature for printed outputs - Enhancing security and authenticity of printed materials
Benefits: - Improved security features for printed materials - Enhanced ability to track and identify printed items
Commercial Applications: Title: Unique Signature Printing Technology for Enhanced Security This technology can be used in industries such as printing, packaging, and document authentication to provide unique signatures for printed materials, enhancing security and authenticity. The market implications include increased demand for secure printing solutions in various sectors.
Prior Art: Readers can explore prior art related to halftone screening, signature encoding in printing, and anti-counterfeiting measures in the printing industry to gain a deeper understanding of the technology.
Frequently Updated Research: Researchers may be conducting studies on advanced encryption methods for signature patterns in halftone screens, as well as applications of this technology in digital printing processes.
Questions about the technology: 1. How does the encoding of signature patterns in halftone screens enhance security in printed materials? 2. What are the potential challenges in implementing this technology in large-scale printing operations?
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.
