Printing System Quality Verification via PRX Data Format
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current commercial printing systems lack a unified data format for interpreting quality requirements for each print job and executing quality verification processes at appropriate times, leading to inefficiencies and increased workload for operators.
Innovation Solution
The introduction of a unified data format, PRX (Print Requirement eXchange), and PQX (Print Quality eXchange) allows for the standardized transmission of quality requirements and reports, enabling the workflow management server to interpret these requirements and coordinate the appropriate quality verification processes within the production system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a unified data format (PRX/PQX) is introduced for quality requirements and reports, then the efficiency of interpreting and executing quality verification processes is improved, but the initial system complexity increases due to the need for standardized data format implementation
Solution Approach 1:
The patent introduces a universal data format (PRX/PQX) that can be used across different printing systems and devices to exchange quality requirements and reports. This standardized format allows various apparatuses to communicate quality information consistently, improving overall system efficiency despite the initial complexity of implementation.
Solution Approach 2:
The unified data format acts as an intermediary standard between different printing apparatuses and the workflow management system. By establishing this common language, the patent enables efficient interpretation and execution of quality verification processes without requiring complex custom integrations for each device.
2Reliability
If quality verification processes are executed at appropriate timings coordinated with print jobs, then the quality assurance is improved, but the process complexity increases due to timing coordination requirements
Solution Approach 1:
The patent determines the quality verification process and its timing in advance based on the print job requirements. By pre-planning when and how quality verification will be executed, the system ensures reliable quality assurance without adding complex real-time coordination requirements during actual printing operations.
Solution Approach 2:
The system executes quality verification processes at appropriate timings and uses the results to ensure quality requirements are met. The feedback from quality verification is integrated into the printing workflow, allowing for real-time quality assurance while maintaining coordinated timing through the standardized data format.
3Extent of automation
If the workflow management server coordinates quality verification processes, then the automation level is improved, but the centralization of control increases the server's operational complexity
Solution Approach 1:
The patent merges the quality verification coordination function into the workflow management server, consolidating control over the entire printing and quality verification process. This centralization improves automation by allowing the server to coordinate all quality verification processes based on the standardized PRX/PQX data formats, reducing the need for separate coordination mechanisms.

AI summary
A printing system comprises an order receiving system, an information processing apparatus, and one or more production systems. The order receiving system receives print data, generates quality requirement data, and sends the print data and the quality requirement data to the information processing apparatus. The information processing apparatus decides a production system to be used based on the received quality requirement data, and generates a print job having identification information of a quality verification process and submits the print job to the determined production system. The production system executes the quality verification process corresponding to the identification information, and if a condition set by the quality verification process is not met, executes an adjustment process for meeting the condition, and executes the print job when the adjustment process has been completed.
