Print Job Setting Conversion for Unknown Workflow Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In production printing, JDFs created by unknown workflow applications cannot be accurately analyzed by lower-level workflow applications and printing equipment units, leading to issues in determining the manufacturer and converting setting information, which results in suboptimal print quality and potential errors in rendering print jobs.
Innovation Solution
An information processing apparatus that converts print job setting information into apparatus setting information using multiple schemes, evaluates the converted settings based on comparison results, and creates rendering data using the scheme with the highest evaluation value to ensure optimal print quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the JDF is converted to apparatus setting information assuming an arbitrary manufacturer, then printing can be performed even when the manufacturer is unknown, but the difference between the quality of printing performed and the finished quality intended increases
Solution Approach 1:
The conversion process is segmented into multiple schemes, each corresponding to a different manufacturer. The system divides the conversion task into separate conversion schemes (first conversion scheme, second conversion scheme, third conversion scheme) and evaluates each one independently to determine which provides the best print quality match.
Solution Approach 2:
The system changes the conversion parameters by selecting different conversion schemes based on the detected workflow application manufacturer. When the manufacturer is known, the system applies the corresponding conversion scheme; when unknown, it evaluates multiple schemes to find the optimal parameter set that minimizes quality difference.
2Manufacturing precision
If the manufacturer of the workflow application is determined to select the appropriate conversion scheme, then print quality is improved, but the system complexity increases when dealing with unknown manufacturers
Solution Approach 1:
The system introduces an intermediary evaluation mechanism that compares conversion results against reference data. The evaluation unit acts as a mediator between the conversion process and the final rendering, assessing which conversion scheme produces the best results without requiring complex manufacturer identification algorithms.
Solution Approach 2:
The system creates copied conversion results for different manufacturers using the same JDF input. By generating multiple versions of the apparatus setting information through different conversion schemes and evaluating them, the system can select the best match without needing to accurately identify the original manufacturer.
3Manufacturing precision
If multiple conversion schemes are evaluated to find the optimal one, then the difference between intended and actual print quality is minimized, but the processing time increases
Solution Approach 1:
The system applies partial action by evaluating only the necessary conversion schemes based on the detected manufacturer. When the manufacturer is known, only the corresponding conversion scheme is applied. When unknown, the system evaluates multiple schemes but can stop early if a sufficient match is found, avoiding unnecessary processing of all possible schemes.
