Document Data Stream Color Management Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the processing of resource-based document data streams, especially those containing color-related data, existing technologies face challenges in accurately reproducing colors across different output media due to variations in medium properties, leading to inconsistencies in color impression and requiring complex color management techniques.
Innovation Solution
The method involves logically linking resource reference data with medium reference data within the document data stream, allowing automatic changes in color management resources when the output medium changes, and utilizing indexed color management resources to simplify color data processing by associating colors with predetermined palettes, thereby ensuring accurate color reproduction across various media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If color management resources are manually selected and configured for each output medium, then color reproduction accuracy can be maintained, but the complexity of color management increases significantly
Solution Approach 1:
The system enables automatic selection of color management resources by linking them to output medium references in the document data stream. The processing system automatically retrieves and applies the appropriate color transformation table when an output medium change is detected, eliminating manual configuration requirements while maintaining color accuracy
Solution Approach 2:
The solution creates a universal color management mechanism that works across different output media types (paper, film, transparencies) through a common approach: embedding medium references in the document data stream that automatically resolve to appropriate color management resources, making the system adaptable to various media without requiring media-specific manual setup
2Adaptability or versatility
If color management resources are embedded in the document data stream, then automatic color adaptation to output medium changes is enabled, but the data transfer volume increases
Solution Approach 1:
The solution extracts only the essential color management resource references (identifiers) from the full color transformation tables and embeds these compact references in the document data stream. The actual color transformation data remains external, reducing embedded data volume while maintaining the ability to automatically adapt colors to different output media
Solution Approach 2:
The color management resource references are nested within the existing document data stream structure, specifically associated with output medium references. This integration allows the color management information to be carried along with the document data without requiring separate data streams or significant additional bandwidth
3Reliability
If established applications are configured for specific printing systems, then they produce consistent results on that system, but they fail to produce expected results when sent to different printing systems
Solution Approach 1:
The solution makes the color management configuration dynamic by linking it to output medium references rather than hardcoding it for specific printing systems. When a document is sent to a different printing system, the system dynamically resolves the color management resources based on the output medium specified in the document data stream, ensuring results are consistent across different printing systems
Solution Approach 2:
The output medium reference acts as an intermediary between the document and the printing system. Instead of directly configuring applications for specific printers, the system uses the medium reference as an intermediate layer that automatically resolves to the appropriate color management resources on any printing system, enabling cross-system compatibility while maintaining consistency
Data Source
AI summary
In a method or device to generate or process a resource-based document data stream with which an output of at least one document on an output medium can be controlled, the document data stream is provided with resource reference data related to at least one color management resource, and medium reference data related to the output medium. The resource reference data and the medium reference data are logically connected with one another such that when the medium reference data changes because the output medium has changed, then the resource reference data is automatically changed to another color management resource.
