Inspection Position Identification for Printed Matter Quality Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In commercial printing, customers face difficulties in flexibly designating inspection targets for print quality, as existing systems require re-designation of inspection positions even when image arrangements change, and lack flexibility in specifying inspection targets.
Innovation Solution
An information processing apparatus that acquires instruction information for quality inspection, determines whether the inspection target is designated by identification information or coordinate information, and identifies the inspection position accordingly, enabling flexible inspection target designation and quality inspection of printed matter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If inspection positions are designated by coordinates, then the inspection position can be precisely specified, but the system requires re-designation when image arrangement changes, reducing flexibility
Solution Approach 1:
The patent uses object identification information (object IDs) that copies or references the logical identity of image objects rather than their physical coordinate positions. This allows the inspection target to be identified by its object identity rather than its position, so when images are rearranged, the same object ID refers to the same logical target regardless of new coordinates
Solution Approach 2:
The patent introduces object identification information as an intermediary between the inspection requirements and the actual image data. Instead of directly linking inspection positions to coordinate systems, the object ID acts as a mediator that decouples the inspection target specification from the physical arrangement, enabling flexible repositioning without re-designation
2Measurement precision
If inspection targets are designated by coordinates, then the position can be accurately identified, but customers cannot flexibly designate inspection targets
Solution Approach 1:
The patent makes the inspection target designation dynamic by allowing switching between coordinate-based specification and object ID-based specification. The system can adapt to different user needs and scenarios, providing coordinate precision when position accuracy is critical and object ID flexibility when targets need to be easily selected or rearranged
Solution Approach 2:
The patent creates a universal inspection designation system that can handle multiple types of target specification (coordinates and object IDs) within a single framework. This multi-functional approach allows the same inspection system to accommodate both precise coordinate-based designation and flexible object-based designation, serving diverse customer needs
3Measurement precision
If coordinate information is used for inspection position, then position can be precisely specified, but errors occur when image arrangement changes
Solution Approach 1:
The patent copies the logical identity of image objects through object IDs rather than relying on coordinate positions. This creates a redundant reference system where the object ID preserves the identity of the target independent of its spatial coordinates, ensuring consistent identification even when arrangements change
Solution Approach 2:
The patent prepares for potential arrangement changes by using object IDs that are assigned beforehand and remain valid regardless of future repositioning. This proactive approach cushions against the reliability issues that would otherwise occur when coordinates become invalid after rearrangement

AI summary
Instruction information on quality inspection of a printed matter is acquired, and it is determined whether the instruction information identifies an inspection target by identification information of an object or by coordinate information. An inspection position is identified in accordance with the determination result, and quality inspection of the printed matter is performed by using the identified inspection position.
