Hyperspectral Decor Template Transfer for Accurate Color Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to achieve high color fidelity in digitizing and printing analog decorative templates, leading to significant chromatic differences between the original and the digital representation.
Innovation Solution
The method involves generating hyperspectral digital images of the analog decorative template, creating decor-specific reference and profile targets, and adjusting these targets to ensure accurate color reproduction by comparing them with actual images using a similarity index, ensuring the similarity index exceeds a predetermined target value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If digital printing is used for personalised invitations, then production costs and lead times are reduced, but the quality and texture of the printed material deteriorates
Solution Approach 1:
The patent uses an analogue template (photograph or artwork) as a copy reference to guide the digital printing process. The template is scanned or photographed and used to create a digital file that maintains the original quality and texture while enabling fast digital production. This copying approach resolves the contradiction by preserving aesthetic quality through template-based reproduction while achieving digital printing speed benefits.
2Manufacturing precision
If analogue templates are used for personalised invitations, then quality and texture are maintained, but production time and costs increase
Solution Approach 1:
The analogue template is prepared and scanned in advance before the actual printing process. By pre-processing the template creation and digitization steps, the system establishes high-quality reference data that can be rapidly reproduced through digital printing. This preliminary action separates the quality-assuring template creation from the fast digital production process, resolving the contradiction between quality maintenance and production speed.
3Adaptability or versatility
If personalised invitations are printed on demand, then inventory costs are reduced, but printing quality and consistency deteriorates
Solution Approach 1:
The system creates a digital copy of the analogue template that serves as a consistent reference for all printings. This digital copy maintains the original quality and texture while enabling reliable reproduction across multiple on-demand printings. The copying process ensures that each personalised invitation maintains consistent quality despite being produced individually, resolving the contradiction between on-demand adaptability and printing consistency.

AI summary
The invention provides a method and an apparatus for adopting analogue decor templates in decor printing, comprising the similarity comparison between at least one of (1) to n hyperspectral digital reference images of the analogue decor template and at least one of (1) to n hyperspectral digital actual images of a substrate with decor, wherein a decor-specific profile target is adjusted such that the digital template of the analogue decor template can be output on a substrate by way of an output medium in such a way that the colour deviation between at least one of (1) to n reference images of the analogue decor template and at least one of (1) to n actual images of the substrate with decor is below a specified target value.
