Image Inspection Apparatus Separating Proof and Final Print Area Designation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image inspection systems face complexity and productivity issues when setting and checking designated areas for image inspection, especially with multiple areas to be designated across numerous print pages, leading to complications and delays in final printing.
Innovation Solution
An image inspection apparatus and system that allows designated areas to be set separately in an application, enabling the combination of a read image from trial printing with designated area information to facilitate easier recognition and correction of errors, thereby simplifying the inspection process and reducing productivity losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If designated areas are set for each read image of proof mode printing, then image inspection accuracy is improved, but operation complexity and time consumption increase significantly
Solution Approach 1:
The patent divides the image inspection process into two distinct modes: proof mode printing where designated areas are not required, and final printing where designated areas are automatically applied. This segmentation allows the system to maintain inspection accuracy for final prints while avoiding the operational burden of manually designating areas for every proof print.
Solution Approach 2:
The system performs preliminary setup by storing designated area information in advance for final printing. During proof mode printing, this pre-stored information is not required, allowing quick operation. The designated areas are prepared beforehand and automatically applied when needed, eliminating the need for repetitive manual designation.
2Reliability
If designated areas are checked for numerous print pages, then inspection completeness is improved, but productivity deteriorates
Solution Approach 1:
The system dynamically adjusts the inspection process based on the printing mode. For proof mode printing with many pages, the system skips the time-consuming designated area checking step while maintaining the capability to perform complete inspection with pre-stored designated area information when final printing is executed.
Solution Approach 2:
The system uses pre-stored designated area information to automatically perform inspections without requiring real-time manual designation. This self-service approach maintains inspection completeness while significantly reducing the time required, as the system serves itself with previously prepared inspection parameters.
3Manufacturing precision
If manual designation of areas is performed for each proof print page, then area accuracy is improved, but time consumption increases
Solution Approach 1:
The system performs the time-consuming area designation task in advance during setup, storing the designated area information for later use. During actual proof printing operations, this pre-prepared information is automatically applied, eliminating the need for repetitive manual designation and significantly reducing time consumption while maintaining area accuracy.
4Reliability
If image inspection is performed on all print pages, then inspection thoroughness is improved, but processing time increases
Solution Approach 1:
The system dynamically adapts the inspection process to the printing stage. For proof mode printing, it performs simplified processing without detailed designated area checking to maintain speed. For final printing, it executes thorough inspection using pre-stored designated area information, ensuring completeness without sacrificing overall processing efficiency.

AI summary
An image inspection apparatus includes a designated area acquisition device that acquires information related to an area designated in a recording medium, wherein when trial printing is instructed, a read image of an image printed on the recording medium in the trial printing and an image of the area generated on the basis of the information related to the area acquired by the designated area acquisition device are combined.
