Print Inspection Reference Image Storage for Controlled Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for storing reference image data in print systems lead to storage capacity shortages due to the need to store data for reuse, and automatic deletion techniques may inadvertently delete data not intended for removal.
Innovation Solution
An inspection apparatus and method that generates and stores reference image data based on print data, allowing reuse without storing the data after inspection, and manages storage based on the inspection method to avoid capacity issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If reference image data is stored for reuse in print systems, then inspection efficiency is improved, but storage capacity is exhausted
Solution Approach 1:
The patent implements automatic deletion of reference image data after a predetermined period. The storage management unit deletes reference image data corresponding to print jobs that have not been executed within a set time frame, thereby freeing storage capacity while preserving recently used data for continued inspection efficiency.
Solution Approach 2:
The patent introduces a dynamic storage management mechanism that actively monitors and manages reference image data based on usage patterns. The system dynamically deletes outdated data and retains recently used data, transforming the static storage structure into a dynamic one that adapts to changing inspection needs over time.
2Quantity of substance
If automatic deletion of reference image data is implemented, then storage capacity is maintained, but unintended deletion occurs
Solution Approach 1:
The patent implements a feedback mechanism where the storage management unit monitors the execution status of print jobs and uses this information to determine which reference image data should be deleted. The system feedbacks based on actual usage patterns, deleting only data corresponding to unexecuted print jobs within the predetermined period, thus avoiding unintended deletion while maintaining storage capacity.

AI summary
The present disclosure makes it possible to avoid the shortage of the capacity of a storage device storing reference image data and maintain the convenience to a user in a case of the reuse of a print job. An inspection apparatus performing an inspection of printed material includes a setting unit configured to set reference image data generated based on print data on the printed material for the inspection and a storing unit configured to store the set reference image data according to an inspection method and hold the stored reference image data in order to reuse it for another inspection even after the inspection is performed.
