Solution Overview
Problem
Existing digital printing systems face significant deviations in printed designs, requiring time-consuming and costly manual adjustments and quality control processes to ensure color accuracy, especially when producing panels from different batches that need to be indistinguishable.
Innovation Solution
A method that compares print measurement data with reference data to adjust print settings automatically, without modifying the digital template, using sensors and an AI model to ensure precise color matching across multiple prints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adaptation of digital print files is performed to correct color deviations, then color accuracy is improved, but time consumption and personnel costs increase significantly
Solution Approach 1:
The system measures the actual printed decor and compares it with the desired reference decor, then automatically feeds back adjustment parameters to the digital printing template. This closed-loop feedback mechanism eliminates manual intervention by continuously monitoring and correcting color deviations through automated parameter adjustment based on measured versus target values.
Solution Approach 2:
The printing system performs self-correction by automatically adjusting its own print parameters based on measured deviations. The system measures its own output, compares it with reference values, and autonomously modifies its printing parameters without requiring external human intervention, enabling the system to service and correct itself.
2Manufacturing precision
If manual adaptation of digital print files is performed to correct color deviations, then color accuracy is improved, but personnel costs and complexity increase
Solution Approach 1:
The system replaces manual mechanical processes (human operators using photo editing software) with an automated measurement and control system. Sensors measure printed colors, processors analyze deviations, and algorithms automatically adjust printing parameters, substituting human-operated mechanical processes with automated electronic control and computation.
Solution Approach 2:
The system introduces an automated measurement and control intermediary between the printing process and the final output. This intermediary consists of measurement devices, data processing units, and control algorithms that mediate between the printed decor and the desired reference, automatically determining and applying corrections without human intervention.
3Manufacturing precision
If quality control checks are performed to verify print file modifications, then print quality is improved, but time consumption and process complexity increase
Solution Approach 1:
The system performs preliminary measurement and adjustment actions before mass production begins. By measuring a test print, determining deviations, and pre-adjusting the digital printing template beforehand, the system ensures subsequent production runs are immediately correct, eliminating the need for repeated quality control checks during production and enabling continuous high-speed manufacturing.
