Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current printer technologies consume significant amounts of ink or toner, leading to frequent cartridge replacements and high costs, with existing methods for reducing consumption either compromising print quality or being inefficient due to varying image types and paper types.
Innovation Solution
A system and method that includes a printer controller software loaded on a computer, which controls the deposition of printer colorant based on identifying printer, colorant, and medium characteristics, allowing users to select print image quality and colorant reduction criteria to optimize ink or toner usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If draft or economy mode is used to reduce ink/toner consumption, then printer colorant usage is reduced, but print quality deteriorates to the point where documents are only usable for quick checks
Solution Approach 1:
The patent applies local quality by analyzing different regions of the printed page and applying different ink reduction strategies. Text regions maintain full quality while image regions undergo more aggressive compression. This allows the system to reduce overall ink consumption while preserving print quality in critical areas where readability and professionalism matter most.
Solution Approach 2:
The system dynamically adjusts ink deposition based on real-time analysis of image characteristics, paper type, and user preferences. Rather than using a static reduction ratio, the patent modifies printing parameters on-the-fly for different sections of the document, optimizing the balance between ink savings and quality maintenance for each specific printing scenario.
2Loss of substance
If a fixed ink reduction amount is applied to all images, then ink consumption is reduced, but image quality deteriorates more than expected for photographic images
Solution Approach 1:
The patent changes multiple parameters simultaneously based on image type detection: for photographs, it uses higher reduction ratios with advanced compression algorithms; for text documents, it applies lower ratios with font smoothing; for line art, it uses threshold-based reduction. This multi-parameter adjustment ensures consistent quality across different image types while maximizing ink savings for each category.
Solution Approach 2:
The system incorporates feedback mechanisms where the quality analysis unit evaluates the impact of ink reduction in real-time and adjusts subsequent reduction levels. If quality degradation exceeds thresholds, the system automatically reduces the ink reduction ratio for that particular image or region, ensuring minimum quality standards are maintained while still achieving overall consumption reduction.
3Manufacturing precision
If economy mode is used to achieve better image output than draft mode, then print quality improves, but ink/toner consumption remains higher than necessary
Solution Approach 1:
The patent segments the printing process into distinct analysis and execution phases, and further segments the document into text regions, image regions, and mixed regions. Each segment is processed with optimized ink reduction parameters tailored to its specific requirements, allowing the system to maintain high quality in text areas while applying aggressive savings in image areas, thus breaking the trade-off between quality and consumption.
Solution Approach 2:
The patent introduces an intermediary processing layer between the document and the printer that analyzes image characteristics and applies intelligent compression algorithms. This intermediary unit acts as a mediator that transforms the original image data into an optimized representation that requires fewer ink deposits while preserving visual quality, thereby decoupling the relationship between ink consumption and perceived print quality.
