Printing Device Detects Rendering Marks to Maintain Image Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing devices face significant cost disparities between full color and black-and-white printing due to the higher expense of cyan, magenta, and yellow print substances, leading to quality degradation in low cost or depletion color modes, where subsequent copies further reduce image quality.
Innovation Solution
A printing device that detects and decodes rendering information from a hidden mark in the source item, allowing it to adjust output settings to prevent further quality degradation by switching to full color mode when necessary, thereby maintaining image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If depletion color mode is used to reduce printing costs, then cost is reduced, but image quality deteriorates
Solution Approach 1:
The system performs preliminary detection of rendering information from the source document before printing. By reading hidden marks or metadata that indicate the original rendering mode, the system can proactively determine whether to use full color or depletion mode, preventing quality degradation before it occurs.
Solution Approach 2:
The system incorporates feedback by detecting rendering information from the source document and using this information to adjust printing parameters. The hidden mark or metadata provides feedback about the original document's color requirements, allowing the system to make informed decisions about print substance usage while maintaining quality where needed.
2Manufacturing precision
If full color mode is used to maintain image quality, then image quality is maintained, but cost increases
Solution Approach 1:
The system applies local quality by using full color printing only for specific regions or elements of the document that require it, while using depletion mode for other areas. By detecting rendering information, the system can identify which parts of the document were originally printed in full color and reproduce only those areas with full color, reducing overall print substance cost while maintaining necessary quality.
Solution Approach 2:
The system dynamically changes printing parameters based on detected rendering information. Instead of using a fixed printing mode for the entire document, the system adjusts color usage, print density, and substance application parameters according to the specific requirements identified in the source document's hidden mark or metadata.
3Quantity of substance
If subsequent copies are made in depletion color mode to save cost, then cost is reduced, but information content is lost
Solution Approach 1:
The system performs preliminary detection of rendering information from the source document before making copies. By identifying which areas contain critical information that requires full color representation, the system can proactively preserve that information in subsequent copies while using depletion mode only for non-critical areas, preventing information loss before it occurs.
Solution Approach 2:
The hidden mark or metadata in the source document serves as an intermediary that carries information about rendering requirements. This intermediary provides the system with guidance on which areas contain important information, allowing it to make intelligent decisions about where to maintain full color quality in copies while reducing costs in other areas.
