Print Data Inspection Region Extraction and Precision Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In digital printing, inspecting multiple pages with varying content is inefficient as it requires setting inspection information for each page, which is burdensome and time-consuming, especially when some objects require high precision while others do not.
Innovation Solution
An information processing apparatus that analyzes print data to automatically extract inspection regions and set precision levels, preparing inspection information including the position and precision level for each region, allowing for efficient inspection without user intervention for each page.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If inspection information is set for each page manually, then inspection precision can be customized for each page, but the operation becomes burdensome and time-consuming
Solution Approach 1:
The inspection device automatically analyzes print data to extract objects and determine inspection regions, then autonomously sets inspection information including precision levels without requiring manual user input for each page. The system serves itself by generating inspection configurations from the print data automatically.
Solution Approach 2:
The inspection device performs preliminary analysis of print data before inspection to extract objects, determine their types, and pre-set appropriate inspection regions and precision levels. This preliminary configuration is stored and automatically applied during subsequent inspection operations.
2Reliability
If inspection is performed on all pages, then complete coverage is achieved, but inspection efficiency decreases due to time consumption
Solution Approach 1:
The inspection device applies different inspection precision levels to different regions based on object types. High-precision inspection is applied only to regions containing objects requiring strict quality control, while other regions use standard or reduced inspection, optimizing the balance between coverage and efficiency.
Solution Approach 2:
The system performs inspection selectively on extracted objects and their surrounding regions rather than entire pages. By focusing inspection on specific objects and their immediate contexts, the system achieves adequate coverage with reduced time consumption.
3Measurement precision
If inspection region is defined for each object, then inspection precision is improved, but device complexity increases
Solution Approach 1:
The inspection device segments pages into multiple inspection regions based on extracted objects. Each object becomes a focal point for defining its own inspection region, allowing precise inspection of critical elements while simplifying the overall process through modular region-based handling.

AI summary
An information processing apparatus includes a processor configured to: analyze print data to be inspected, to extract a region including an object included in the print data as an inspection region, for which a print result of the print data is to be inspected; set a precision level of an inspection to be performed on the extracted inspection region; and prepare inspection information including a position of the extracted inspection region and the precision level of the inspection to be performed on the inspection region, to set inspection information to be used for an inspection of the print result to the print data.
