Variable-Content Document Forming With Physical Print Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital printing technologies face challenges in accurately forming electronic documents on physical media due to errors caused by unexpected events and device limitations, leading to discrepancies between the expected and actual images, especially when content depends on variable factors and access is restricted.
Innovation Solution
A method involving a first information processing apparatus that obtains identifiers and associated locations, sends document information to an image forming apparatus and a second processing apparatus, generates a second electronic document by retrieving corresponding content, and compares it with the formed physical document to detect and correct differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If digital printing is used to form electronic documents on physical medium, then document formation capability is improved, but errors and discrepancies between expected and actual images occur
Solution Approach 1:
The patent implements a feedback mechanism where the formed physical document is scanned to obtain an actual image, which is then compared with the expected electronic document image. The comparison results are fed back to identify discrepancies and enable corrective actions, thereby improving image accuracy while maintaining digital printing capabilities.
Solution Approach 2:
The system performs preliminary actions by generating an expected image from the electronic document before the actual formation process. This expected image serves as a reference for subsequent comparison with the actual formed document, allowing proactive identification and correction of potential errors.
2Loss of information
If content is retrieved from various devices to create complete electronic documents, then document completeness is improved, but access restrictions and security issues arise
Solution Approach 1:
The patent introduces an intermediary system that manages content retrieval from various devices. This intermediary handles authentication, authorization, and secure transfer of content, enabling complete document assembly while respecting access restrictions and security requirements through controlled intermediary operations.
3Measurement precision
If comparison between electronic document and formed physical document is performed, then error detection capability is improved, but processing time and resource consumption increase
Solution Approach 1:
The patent extracts only the necessary comparison operations from the overall document formation process. By focusing comparison efforts on critical elements and using efficient image processing techniques, the system achieves high error detection capability while minimizing unnecessary processing time and resource consumption.

AI summary
A method comprising obtaining, by a first information processing apparatus, a first electronic document to be formed: obtaining, by said first information processing apparatus, at least one identifier, each of said at least one identifier corresponding to a respective content to be formed as part of said first electronic document, and each of said at least one identifier having one or more associated locations indicating where on said first electronic document said corresponding content is to be formed: sending document information, by said first information processing apparatus, to an image forming apparatus and a second information processing apparatus, said document information comprising: said first electronic document, for each of said at least one identifier, said one or more associated locations, and, for each of said at least one identifier, said corresponding content or said identifier: obtaining, by said image forming apparatus and said second information processing apparatus, based on said document information, a second electronic document, said second electronic document being generated by, for each of said at least one identifier, retrieving said corresponding content, and including into said first electronic document, said corresponding content in association with said one or more associated locations: forming, by said image forming apparatus, a physical document from said second electronic document: obtaining, by said second information processing apparatus, an image of said physical document: comparing, by said second information processing apparatus, said second electronic document and said image to detect whether a difference exist: and sending, by said second information processing apparatus, a comparison result to said image forming apparatus, said comparison result including, if a difference is detected, information for causing said image forming apparatus to interrupt an operation and display said comparison result on a display unit. A computer program, an information processing apparatus, a system are also disclosed.
