Imaging Data Stream Color Rendering Order
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Line Conditioned Data Stream (LCDS) imaging models in digital printing systems are limited to monochrome and highlight color, resulting in error messages and poor color quality when attempting to print with multiple non-monochrome colors, as they fail to approximate the user's intent in the color printing process.
Innovation Solution
Implementing an improved imaging data stream and color-imaging model that specifies an imaging order for rendering, where all fills, image data, text, logos, and variable data are called out in a specific order, allowing for actual specified colors to be used, enabling full-color rendering and overcoming the limitations of traditional LCDS systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional LCDS imaging model is used, then system compatibility and simplicity are maintained, but color quality and user intent approximation deteriorate
Solution Approach 1:
The patent changes the fundamental parameters of the imaging model from monochrome/highlight color to full color imaging. This involves modifying how color data is processed and rendered, allowing the system to output multiple non-monochrome colors while maintaining LCDS compatibility. The parameter change enables accurate color reproduction without requiring complete system redesign.
Solution Approach 2:
The patent segments the color imaging process into distinct components: color space conversion, imaging order determination, and separation rendering. By dividing the complex color imaging task into manageable segments, the system can handle full-color LCDS data streams while maintaining compatibility with existing print engine architecture.
2Adaptability or versatility
If multiple non-monochrome colors are specified, then color variety increases, but error messages and rendering failures occur
Solution Approach 1:
The patent introduces dynamic imaging order determination based on color specifications. Instead of a fixed rendering sequence, the system dynamically adjusts the imaging order according to the specific colors present in the data stream. This dynamic adaptation allows multiple non-monochrome colors to be rendered reliably without generating error messages.
Solution Approach 2:
The patent introduces an intermediary color management process that translates full-color LCDS specifications into renderable formats. This intermediary layer converts the color data and determines imaging order before passing to the print engine, acting as a mediator between the sophisticated color requirements and the print engine's capabilities, thereby ensuring reliable rendering.
3Manufacturing precision
If imaging order is applied to overlapping objects, then color quality and user intent approximation improve, but processing complexity increases
Solution Approach 1:
The patent performs preliminary determination of imaging order before actual rendering occurs. By analyzing all objects and their color properties in advance, the system establishes the correct imaging sequence upfront. This preliminary action ensures that overlapping objects are rendered in the correct order to match user intent, while the actual rendering process remains straightforward.
