Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital printing methods require manual separation of colors for each set of printing parameters, leading to increased production time and costs, and result in a loss of image quality when adapting to different printing installations or materials.
Innovation Solution
A method that generates digital decoration data in the RGB color space, processes it to create processed decoration raw data, calculates color-space-profiled production data and separation data for specific printing parameters, and outputs the image using a digital printer, allowing flexibility across various installations and materials without repeated retouching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual color separation is performed for each set of printing parameters, then color accuracy for specific printing conditions is improved, but production time and costs increase significantly
Solution Approach 1:
The patent performs color space profiling and separation data calculation in advance for multiple different printing parameter sets, storing them as pre-processed data. When a specific printing task arises, the corresponding pre-calculated separation data is retrieved and applied directly, eliminating the need for manual color separation at the time of printing. This preliminary processing of color data for various printing conditions resolves the contradiction by preparing accurate color separation data ahead of time without increasing actual production time during printing operations.
2Manufacturing precision
If color space profiling is performed for each printing parameter set, then color reproduction accuracy is improved, but the complexity of the processing system increases
Solution Approach 1:
The patent creates a library of pre-calculated color space profiles and separation data for different printing parameter sets, storing them as reusable data copies. Instead of performing complex color space profiling calculations in real-time for each printing task, the system retrieves appropriate pre-computed profiles from storage. This copying and reuse of pre-processed color data maintains high color reproduction accuracy while significantly reducing the computational complexity required during actual printing operations.
3Adaptability or versatility
If digital printing is used instead of gravure printing, then flexibility and variability in print design are improved, but manufacturing precision and color consistency deteriorate
Solution Approach 1:
The patent employs color space profiling that adapts digital printing parameters to match the color characteristics of the target carrier material and printing conditions. By calculating and storing separation data for multiple different printing parameter sets, the system can adjust color reproduction parameters to maintain consistency across different materials and conditions. This parameter adaptation allows digital printing to achieve gravure-like color consistency while preserving the flexibility and variability of digital printing processes.
