Print Inspection Time Prediction for Continuous Paper Speed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing systems face inefficiencies in inspection processes, leading to potential waste and reduced productivity due to incomplete inspection of continuous paper, which can result in suspended printing and user intervention for reprinting.
Innovation Solution
An information processing system that utilizes a neural network model to estimate inspection time based on input information about the print job, printer, and inspection apparatus, allowing for the determination of optimal printing speed to ensure timely completion of inspections before continuous paper reaches the stack position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inspection is performed on each sheet at the printer, then print quality can be verified, but printing speed is reduced and productivity decreases
Solution Approach 1:
The inspection process is initiated before the printing operation completes. The system predicts inspection completion timing in advance and compares it with the paper stack position timing, allowing the printer to prepare and continue operations without waiting for inspection to finish, thus maintaining high printing speed while ensuring quality verification
2Productivity
If printing speed is increased, then productivity improves, but inspection cannot be completed before paper reaches stack position, causing waste
Solution Approach 1:
The system continuously monitors and predicts the timing of inspection completion and paper stack position, using this feedback information to dynamically adjust printing speed. When inspection is predicted to complete before paper reaches the stack position, the system can safely increase speed; otherwise, it reduces speed to prevent waste, optimizing both productivity and material efficiency
3Measurement precision
If inspection time is extended to ensure complete inspection, then inspection accuracy improves, but printing is suspended and user intervention is required
Solution Approach 1:
The system performs preliminary prediction of inspection completion timing and compares it with paper stack position timing before printing suspension occurs. This allows the system to proactively adjust printing speed to ensure inspection completion without actual suspension, maintaining both inspection accuracy and continuous printing operation
