Gloss-Based Surface Conditioning for Accurate Color Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for matching the color and appearance of damaged vehicle coatings are inefficient due to variations in atmospheric conditions and surface preparation, leading to unreliable selection of aftermarket refinish coatings that match the original equipment manufacturing (OEM) coatings.
Innovation Solution
A system and method that uses a gloss meter to determine if a surface is properly conditioned by comparing its gloss to a minimum gloss threshold, ensuring accurate characterization of the surface's color and appearance, which reduces measurement offsets and aids in selecting the correct matching coating composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If surface preparation procedures are implemented to ensure accurate color measurement, then measurement precision is improved, but device complexity and ease of operation deteriorate due to additional monitoring requirements
Solution Approach 1:
The system performs preliminary gloss measurement and surface conditioning assessment before the actual color measurement takes place. By evaluating surface gloss levels in advance and conditioning the surface to meet minimum thresholds, the system ensures that subsequent color measurements are taken on properly prepared surfaces, thereby improving measurement precision without requiring complex monitoring during the measurement process itself.
2Reliability
If multiple refinish coating compositions are tested to find the best match, then reliability of color matching is improved, but loss of time increases due to repeated testing
Solution Approach 1:
The system replaces the mechanical trial-and-error process of applying and visually inspecting multiple refinish coatings with an automated optical measurement system. The spectrophotometer objectively measures color properties and compares them against a database of OEM coatings, eliminating the need for repeated physical application and visual assessment, thereby significantly reducing time loss while maintaining or improving matching reliability.
3Measurement precision
If gloss measurement is used to verify surface conditioning, then measurement precision is improved, but device complexity increases due to additional measurement equipment
Solution Approach 1:
The system employs a multi-functional measurement approach where the same spectrophotometer or color measurement device is used to perform both gloss measurement and color characterization functions. By integrating multiple measurement capabilities into a single instrument, the system achieves precise surface conditioning assessment through gloss measurement without requiring separate dedicated gloss meters, thereby minimizing the increase in device complexity while maintaining measurement precision.

AI summary
Methods and systems for matching color and/or appearance of a surface of an object are provided. In one example, method includes determining a gloss of the surface of the object at one or more angles. The gloss is compared to a minimum gloss threshold to determine a condition of the surface of the object. If the gloss is at or exceeds the minimum gloss threshold, the surface is properly conditioned. If the gloss is less than the minimum gloss threshold, the surface is improperly conditioned. The color and/or appearance of the surface of the object is characterized if the surface is properly conditioned.
