Print Inspection With Automatic Text Orientation Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print sheet inspection systems require manual registration of text string orientation information, which becomes laborious when dealing with varied orientations or large numbers of pages, leading to inefficiencies.
Innovation Solution
An inspection system that automatically extracts and transmits text string orientation information along with image data, allowing for accurate comparison between printed and reference images without reducing conveyance speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual registration of text string orientation information is performed, then inspection accuracy is improved, but user labor and time consumption increase significantly
Solution Approach 1:
The system performs self-service by automatically extracting text string orientation information from print data without requiring manual user input. The information processing apparatus autonomously analyzes the print job and determines text orientations, eliminating the need for manual registration while maintaining inspection accuracy.
Solution Approach 2:
The system performs preliminary action by extracting and storing text string orientation information during the print job processing stage, before the actual inspection occurs. This advance preparation ensures that orientation data is readily available when needed for inspection, eliminating the need for manual registration at inspection time.
2Measurement precision
If manual registration of text string orientation information is performed, then inspection accuracy is improved, but operation complexity increases for varied orientations and large print jobs
Solution Approach 1:
The system handles complex orientation analysis automatically through self-service mechanisms. The information processing apparatus independently processes print data to extract text string orientations, regardless of how varied or numerous they are, without requiring user intervention or complex manual configuration.
Solution Approach 2:
The system replaces the mechanical manual registration process with an automated information processing system. Instead of manually inputting orientation data, the system uses computational methods to automatically extract and process text string orientation information from digital print data, simplifying operation regardless of complexity.
3Productivity
If automated extraction of orientation information is implemented, then productivity is improved, but system complexity increases
Solution Approach 1:
The information processing apparatus performs multiple functions: it processes print jobs, extracts text string orientation information, and provides this data to the inspection apparatus. By consolidating these functions in a single multi-functional system, productivity improves without proportionally increasing overall system complexity.
Solution Approach 2:
The information processing apparatus serves as an intermediary between the print job data and the inspection apparatus. It automatically extracts and transmits necessary orientation information, bridging the gap between printing and inspection processes while maintaining system integration and managing complexity.
Data Source
AI summary
The information processing apparatus receives a print job from an external apparatus and generates, from print data included in the print job, image data for printing and image area attribute information related to content for each area included in an image to be printed. In addition, for an area in which the image area attribute information indicates a text string attribute, the information processing apparatus extracts, from the print data, direction information related to an orientation of a text string and transmits, to the printing apparatus, the image area attribute information and the direction information, together with the image data for printing. The inspection apparatus inspects a printed product according to the image data for printing, by comparing a read image of the printed product, and a reference image, which is received image data for printing, according to the image area attribute information and the direction information.
