Printing System Ink Usage Adjustment for Cost Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink usage estimation in printing operations often proves inaccurate due to discrepancies between the distribution of content in a production print run and the sample used for estimation, leading to potential financial losses for print shops, especially in large-scale jobs.
Innovation Solution
A method that actively monitors ink usage during printing by establishing a baseline average for a initial set of pages, comparing it to the estimated usage, and implementing corrective actions to adjust ink usage for subsequent pages to ensure costs align with estimates, using a printing system that dynamically adjusts ink use based on real-time data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ink usage is estimated based on a sample, then the estimation process is simple and quick, but the accuracy of ink usage estimation deteriorates due to distribution discrepancies between sample and production print run
Solution Approach 1:
The patent implements a feedback mechanism where actual ink usage from a baseline set of pages is measured and compared against estimated ink usage. Based on this comparison, the system automatically adjusts ink usage for subsequent pages to stay within budget constraints. This closed-loop feedback system resolves the contradiction by providing accurate real-time monitoring without requiring complex pre-analysis of the entire print run.
Solution Approach 2:
The system performs preliminary action by establishing a baseline ink usage rate from an initial set of pages before full production begins. This baseline measurement allows the system to proactively adjust ink usage for remaining pages, preventing budget overruns before they occur. The preliminary baseline establishment simplifies subsequent monitoring while maintaining high accuracy.
2Reliability
If ink usage is adjusted in real-time during printing, then cost control improves, but the operational complexity and monitoring requirements increase
Solution Approach 1:
The system implements self-service by automatically monitoring ink usage, comparing it against estimates, and adjusting ink application without human intervention. The printing system autonomously makes corrective adjustments to stay within budget, eliminating the need for manual monitoring and complex operational procedures while maintaining reliable cost control.
Solution Approach 2:
Real-time feedback loops continuously monitor actual ink consumption and automatically adjust subsequent pages' ink usage. This automated feedback mechanism maintains reliable cost control while keeping operations simple, as the system handles all adjustments autonomously without requiring complex manual intervention.
3Productivity
If the baseline average ink use is established from a small initial set of pages, then the monitoring process is efficient, but the representativeness of the baseline may be insufficient
Solution Approach 1:
The system applies dynamics by continuously adapting the ink usage rate based on real-time measurements. Rather than relying on a fixed baseline from a small sample, the system dynamically adjusts ink application for each subsequent page based on actual consumption patterns observed so far. This dynamic approach maintains monitoring efficiency while improving representativeness as more data becomes available during the print run.
Data Source
AI summary
A printing system includes a printing device, a color management server, and a client device. An estimated ink use is determined for a print job within printing system. After printing operations, a baseline average ink use is determined for a set of printed pages of the print job. If the baseline average ink use varies from the estimated ink use, then a corrective action is taken to adjust ink use to be closer to the estimated ink use. The corrective action is a global corrective action for the entire document of the print job or a targeted action that adjusts only specified features or pages of the document.
