Printed Document Inspection Timing for Conveyance-Limit Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing systems face challenges in accurately determining the time required for inspecting printed sheets, leading to incomplete inspections and difficulty in ensuring all areas are inspected within a time limit, especially when varying conditions such as character string or barcode data affect inspection time.
Innovation Solution
An information processing apparatus that includes a recognition unit to recognize printed contents, an acquisition unit to acquire attribute values, and a notification unit to inform users whether the inspection can be completed within a time limit, allowing for precise planning and completion of inspections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If inspection is performed on all printed sheets within the conveyance time, then inspection completeness is improved, but inspection accuracy deteriorates due to insufficient time for thorough analysis
Solution Approach 1:
The system performs preliminary actions by calculating the inspection required time for each printed sheet before actual inspection based on object information (number of character strings, barcodes, images, etc.). This allows the system to plan inspection priorities in advance, ensuring that sheets with shorter required times are inspected first, thereby guaranteeing that all sheets can be inspected within the conveyance time limit while maintaining adequate inspection quality.
2Loss of time
If inspection time is reduced to meet conveyance time limits, then productivity is improved, but inspection quality deteriorates
Solution Approach 1:
The system calculates the inspection required time for each printed sheet in advance based on object information such as the number of character strings, barcodes, and images. This preliminary calculation enables the system to determine the minimum inspection time needed for each sheet, ensuring that inspection quality is maintained while optimizing the overall inspection time to meet conveyance time limits.
Solution Approach 2:
The system dynamically adjusts inspection priorities based on the calculated inspection required times. Sheets with shorter required times are assigned higher priorities and inspected first, while sheets with longer required times are inspected later. This dynamic priority adjustment ensures that inspection quality is maintained for all sheets while optimizing the use of available conveyance time.
3Productivity
If operator performs manual inspection setting to reduce inspection time, then productivity is improved, but operation complexity increases
Solution Approach 1:
The system performs self-service by automatically calculating the inspection required time for each printed sheet based on its object information (number of character strings, barcodes, images, etc.). This eliminates the need for operators to manually perform inspection setting, thereby improving productivity while reducing operation complexity. The system autonomously determines inspection priorities and allocates time resources without human intervention.
4Ease of operation
If inspection priority is calculated based on object information only, then ease of operation is improved, but calculation accuracy deteriorates due to varying inspection conditions
Solution Approach 1:
The system improves calculation accuracy by introducing additional parameters beyond basic object information. Specifically, it calculates inspection required time based on the number of character strings, barcodes, and images, as well as their data amounts and sizes. These parameter changes enable more accurate time estimation while maintaining ease of operation through automated calculation based on readily available print job information.

AI summary
An information processing apparatus inspecting printed contents of a printed sheet, the information processing apparatus includes a recognition unit configured to recognize the printed contents printed on the sheet, an acquisition unit configured to acquire an attribute value from information recognized by the recognition unit, a specification unit configured to specify a time required for inspection of the printed contents of the sheet by using the attribute value acquired by the acquisition unit, and a notification unit configured to issue a notification to a user based on a result of comparison between the required time specified by the specification unit and a time limit for inspection of the printed contents.
